What decentralization means for Base

Base’s mission is to build a global onchain economy that increases innovation, creativity, and freedom. We believe this is only possible on a decentralized platform. This is why Base is (1) built on Ethereum, the most secure and decentralized L1, (2) built on the open and permissionless OP Stack, and (3) upholds key Neutrality Principles.

We've been focused on continuously decentralizing, and today we're excited to announce that Base is now at Stage 1 Decentralization.

Achieving Stage 1 Decentralization means Base now has stronger security guarantees and reduced trust assumptions. With fault proofs and a decentralized Security Council in place, network functionality and upgrades are in the hands of a broad set of diverse stakeholders. This creates a more resilient foundation for apps, assets, and the global onchain economy on Base, so that:

1. Builders have infrastructure certainty — the platform can't change the rules unexpectedly

2. The network becomes more resilient, with no single point of failure

3. Everyone can participate in securing and verifying the network

Decentralization stages

Vitalik Buterin's decentralization framework lays out a clear path for Layer-2 rollups on Ethereum, like Base, to progressively and safely decentralize. This framework describes three stages of decentralization:

• Stage 0, or "full training wheels", is a stage where all rollup transactions are posted onchain, but the validity checks of these transactions are done by the chain's operator. State verification is centralized and dependent upon the chain operator.

• Stage 1, or "limited training wheels", introduces a running fault proof or validity proof scheme with the practical authority to accept or reject state roots. It includes a decentralized override mechanism controlled by a diverse set of stakeholders, reducing dependence on chain operators alone.

• Stage 2, or "no training wheels", represents full decentralization, where no group of actors can, even unanimously, post a state root other than the output of the code (except in clearly defined bug scenarios).

How we got to Stage 1 decentralization

Our path to Stage 1 decentralization involved two key milestones:

1. Fault Proofs on Mainnet

In October 2024, we launched Fault Proofs on Base Mainnet after close collaboration with Optimism to bring the OP Stack Fault Proof System to Base. Fault Proofs enable:

• Permissionless proposals: Anyone can propose claims about the state of Base, removing reliance on a central party for state verification.

• Permissionless challenges: If a faulty or fraudulent claim is made, anyone can challenge it within 3.5 days by running the open-source challenger software, with economic incentives for successful challenges.

This dramatically increased the decentralization of Base by allowing anyone to permissionlessly withdraw their funds from Base L2 to Ethereum L1 without relying on centralized actors.

2. Decentralizing upgrades via a Security Council

The final requirement to achieve Stage 1 Decentralization was to further decentralize control of contract upgrades. To do this, Base contract upgrades must now be approved by a diverse group of stakeholders from across the Ethereum ecosystem.

The Security Council for Base consists of 10 independent entities from various jurisdictions. To achieve consensus, the Security Council, Optimism, and Base collectively must reach at least a 75% approval threshold to implement a Base upgrade. This setup ensures that no single entity has enough power to control the upgrade process on its own. As a result, the group responsible for implementing upgrades, which currently includes Base and Optimism, is larger and more decentralized.

What’s next?

While reaching Stage 1 Decentralization is a significant achievement, our journey toward full decentralization continues. Looking ahead, we're focused on:

• Additional proof systems — We're working towards having multiple active proof systems live on Base, to further enhance security and decentralization. A promising avenue we are exploring is ZK-based fault proof systems.

• Advancing toward Stage 2 — We’re committed to further decentralizing and achieving Stage 2. We will continue taking steps toward that goal, including enabling the Security Council to provably detect and adjudicate bugs via the multi-proof system.

Today's achievement of Stage 1 Decentralization fulfills one of our key strategic pillars for 2025: "Base is for everyone." By decentralizing Base, we're building the foundation needed to bring everyone, everywhere onchain and creating a truly global economy that increases innovation, creativity, and freedom.

We're excited to continue building on the Base and Ethereum vision of a more open, decentralized, global onchain economy that is accessible to all.

Base is building for the long-term

Base’s mission is to build a global onchain economy that increases innovation, creativity, and freedom. To further our mission, we need to continue making Base more powerful, easier to use, and faster than ever. We are focused on cultivating an ecosystem of long-term people playing long-term games. We want to support passionate builders who are creating products that solve real needs for real people.

Today, we’re introducing three new building blocks to empower everyone to build onchain: Flashblocks to make Base faster, Base Appchains to help Base scale, and Smart Wallet Sub Accounts to make Base simpler to use.

• Making Base faster: Flashblocks make Base 10x faster by bringing effective block times from 2 seconds to 200 milliseconds; the fastest EVM chain to date. We’re inviting builders to start testing Flashblocks on Base Sepolia testnet today.

• Making Base more powerful: Base Appchains are Layer-3 chains on Base to help apps scale through dedicated blockspace, powered by the op-enclave framework. Appchains are a natural evolution for apps spending significant amounts on gas credits for their end users.

• Making Base simpler: Smart Wallet Sub Accounts are now live on Base testnet — simplifying the UX on Base by reducing wallet pop-ups, improving security, and removing the need to manually manage different onchain accounts.

Base is fast: Flashblocks are now live on testnet

People expect near-instant responses when interacting with apps, and a snappy user experience is key to enabling the global onchain economy.

With Flashblocks, a technology built by Flashbots, Base chain will have 200-millisecond “preconfirmation blocks”. This will make Base 10x faster than it is today, and the fastest EVM chain to date.

Flashblocks are partial blocks issued by the block builder and streamed to nodes every 200 milliseconds, allowing users to experience early confirmation times with native revert protection. This architecture draws inspiration from innovations in block propagation and execution — such as Solana’s shreds and Celestia's data squares — while introducing novel optimizations for the rollup context. Learn more about how Flashblocks work in Flashbots’ documentation.

Flashblocks are now live on Base Sepolia testnet, with a path to mainnet in Q2. See the demo and start building with Flashblocks today.

Base is powerful: Base Appchains are now live

Base Appchains are Layer-3 chains that provide dedicated blockspace for apps looking to scale further on Base. High traffic, mature apps can take advantage of dedicated infrastructure powered by Coinbase Developer Platform (CDP). Apps that are spending significant funds sponsoring gas (such as with CDP Paymaster) should consider launching an Appchain for a more customized experience to meet demand.

Base Appchains are:

• Built for scale: Using op-enclave, chain state is proven immediately using AWS S3 and AWS Nitro Enclaves. More technical details on how and why we built this can be found in our Engineering Blog. Each Appchain is supported by enterprise-grade infra, with a fully managed sequencer and nodes, maintenance and upgrades, and a ready-made block explorer.

• Customizable: Appchains offer a series of customization options, including custom gas tokens, permission allowlists, and custom fee logic.

• Builder-friendly: Appchains are managed through CDP with builder-friendly pricing and compatibility with Base builder tools like Smart Wallet and CDP Paymaster.

Blocklords, Super Champs, and Metacade are launching Appchains to meet the high demands of onchain gamers. Proof 8 and MVL offer real-world services that must operate at the scale Base Appchains are prepared to deliver. Decentralized Pictures is launching an Appchain on Base because of the throughput and scalability needed to distribute onchain cinematic art. Horizen’s Base Appchain will support real-world privacy applications, benefitting from Appchain programmability.

Base is simple: Smart Wallet Sub Accounts are now live on testnet

Over the past year, embedded app wallets have become popular because of their ease of use. However, they can also lead to disjointed experiences — forcing users to juggle multiple accounts, fund each separately, and keep track of assets spread across different accounts.

Smart Wallet Sub Accounts significantly improve UX for end users and DevX for builders. With fine-grained spend limits and the benefits of a single universal account, we are moving closer to a world where onchain apps “just work”. With Smart Wallet Sub Accounts:

• Users can manage all of their onchain accounts from one universal wallet, removing the need to manually manage assets across multiple apps.

• Users encounter less friction, with fewer signatures, fewer pop-ups, and a streamlined onchain experience.

• Users can securely fund new accounts directly from their universal wallet with spend permissions, helping solve the cold start problem for builders.

Smart Wallet Sub Accounts are powered by our new underlying accounts framework — combining spend permissions, hierarchical account ownership, and a new ERC developed by the Base team.

Smart Wallet Sub Accounts are ready for integration on Base testnet today, and will be live on mainnet in Q2.

Read our engineering blog to dive into the technical details of Sub Accounts.

Base is for builders

Since day one, Base’s goal has been to empower builders with the tools to create world-class onchain apps. With these new building blocks, we’re making Base faster, simpler, and more powerful than ever before.

And to bring it all together, we launched a new hub — featuring tools, guides, stories, and more — to serve as the home base for builders creating the onchain future:

• A new website with everything you need to build, scale, and monetize your onchain app. Start building today at base.org/builders.

• A new social handle to keep you in the loop on everything that’s happening in the Base builder community. Follow @buildonbase.

• A new GitHub for our open-source codebase, for those ready to roll up their sleeves and contribute directly to Base. Get involved at github.com/base.

What will you build?

Coinbase Wallet and Base are committed to building a global onchain economy that increases innovation, creativity, and freedom. To achieve this mission, we need to make getting onchain as easy as possible – in every country in the world. However, a common barrier in many countries is being able to purchase crypto with local currency. Verification processes can be long and conversion rates lead to high fees.

To solve this, Coinbase Wallet is integrating with Onboard, a global peer-to-peer cryptocurrency exchange. With Onboard P2P, Coinbase Wallet users can purchase crypto using local currency from a network of seller merchants in as little as 5 minutes, with no need for ID verification if you buy under $100 USD in total.

How Onboard Works

Onboard operates a decentralized peer-to-peer exchange protocol that connects local buyers and sellers of cryptocurrency in different markets. The process works like this:

• Buyers select the cryptocurrency and amount

• Onboard matches the buyer to a seller in their region

• An escrow is set up to facilitate a secure trade for both parties.

• Once funds are confirmed, the cryptocurrency is released to the buyer

If you’re in Nigeria, try out the Onboard experience in Coinbase Wallet today. Simply select Pay with Onboard P2P when buying crypto. You’ll be directed to a simple and secure experience with Onboard, where you can select local payment options and be connected to a seller. Once payment is made, you’ll receive your crypto in as little as 5 minutes.

Expansion to More Countries in 2025

Nigeria is the first of many countries where Coinbase Wallet is offering easier access to Onboard’s peer-to-peer exchange. Onboard is aiming to enable its payment option in over 50 countries in the coming year, with Argentina, India, Indonesia, Kenya, the Philippines, and Turkey support coming soon. Contact Onboard if you’d like to be a merchant in these countries.

Let's talk about the future of Coinbase Wallet.

1,705

11:02 AM • Feb 4, 2025

Last year, we made great progress with Coinbase Wallet by simplifying onboarding and transactions with Smart Wallet, building more options to buy crypto in over 140 countries, and rewarding people who bring their money onchain. We also announced that Coinbase Wallet and Base would join forces to help power the onchain flywheel.

Base supports developers who build onchain, Coinbase Wallet onboards people, and those people discover and experience great apps. This is the way the flywheel should work. But, the reality is that it’s not working as well as it should today.

We’re seeing all-time highs in downloads for Coinbase Wallet, but these people come onchain to buy a coin, and then stop there. Our goal is to take them further.

That’s what 2025 is all about — doing more than just getting people through the door by connecting them to the incredible products that builders are creating every day. It’s about helping builders go viral with their products, coins, and creativity.

To do this, we’re building the next evolution of Coinbase Wallet.

Coinbase Wallet’s big rocks for 2025

We’re rebuilding Coinbase Wallet into an open platform that anyone can build and grow into, and we’re going to help builders go viral. To do this, we’re focusing on:

• Helping apps get discovered. We’re adding a social graph to the Coinbase Wallet app by leveraging Farcaster, an open, social protocol that anyone can build on top of. We’ll use Farcaster to power a full social feed, as well as mini-apps with Frames v2. These are bite-sized onchain experiences — created in minutes — allowing users to take actions without leaving the feed.

• Making Coinbase Wallet 10x faster and easier to use. We’re rewriting everything from the ground up. We started this late last year, have made incredible progress, and will be rolling out the first beta in the coming months.

• Evolving our brand to represent more than Coinbase Wallet and Base.  Since 2023, we’ve seen an explosion of creativity from the community and feel that we need a brand that not only represents us, but something that the community can use and own themselves. It takes everyone working together to build a better internet.

Here’s what’s changing

As we work to carry out this vision, we’re excited about what this means for the onchain economy.

• First, we’re going to make Coinbase Wallet work incredibly well for payments. Crypto payments are a core use case and a key foundation for everything else, and today they’re still too hard. 2025 is the year we make payments just work.

• For builders, we’re going to help them reach millions of users coming onchain with mini-apps supported across the social feed. It’ll be the easiest way to get distribution and go viral.

• For traders, we’re going to accelerate the onchain network that makes viral token moments happen. We’re building a wallet that lets you follow, trade, and share with your social network, all in one place.

• For creators, we’re going to help you connect and earn from your creativity, with millions of people ready to join your community.

• And for everyone onchain, we’re going to make it incredibly easy for you to find the apps you want to use, the coins you want to buy, the projects you love, and the communities you want to be a part of.

2025 will be the year Coinbase Wallet becomes the place for distribution for builders, creators, and communities. We have a lot to do, and we can’t do this alone.

Want to be a part of it? Start bringing your content onchain, and start experimenting with mini-apps that can be part of the onchain social graph. The more people we have building on top of open standards like Farcaster, the faster we bring the world onchain.

Join us on Farcaster and X as we share how all this will unfold, and to be a part of the new beta experience soon.

Our mission

Our mission is to build a global onchain economy that increases innovation, creativity, and freedom. A new internet, built by the people, for the people.

Success looks like the whole world onchain — millions of builders and billions of people — and the only way we get there is by connecting people, builders, and businesses. By inviting the world to build alongside us and building in the open, we’re creating a new kind of internet that supports an open, thriving economy for everyone.

One of the biggest pieces of feedback we consistently hear is that it’s still too hard to join this new economy. This year, we’re focused on simplifying the message, making the products just work, and bringing the whole world onchain.

Our big, hairy, audacious goals for 2025

To bring a billion people onchain, we have to work hard and push ourselves beyond our comfort zones. If we’re hitting every milestone we set, we’re not aiming high enough. So, as we enter 2025, we set some big, hairy, audacious goals that both excite and scare us:

• 25 million people

• 25 thousand developers

• 250 Mgas/s blockspace capacity

• $100 billion assets on platform

• 1 billion transactions on Base in October

When we look back at the end of this year, we’ll know we’re on track if we reached for these goals and they challenged us to go above and beyond. With a bit of luck and a lot of determination, we have a shot at achieving them.

Our five strategic pillars for 2025

To achieve these goals, in 2025, we need to work together. And that means focusing our collective efforts on things that accelerate each other and help us be stronger, together. To help keep us all rowing in the same direction, we want to pull back the curtain and share what the Base core team is doing to make it happen. Our hope is that this inspires you to build with us.

#1 Base is for builders

We will build powerful and open tools that enable anyone to build world-class onchain apps. Whether you’re an advanced onchain developer, a web2 convert, or a total beginner, we want to enable you to build and make an impact.

1. Double down on OnchainKit and the building blocks for world-class apps

2. Ship new tools to help builders embrace AI agents and mini-apps

3. Enable gasless experiences and scale with Paymasters and L3s

#2 Base is for apps

We will nurture a vibrant ecosystem of connected, open onchain apps that grow the number of people using Base. More apps translate to more concrete reasons for every single person to get onchain.

1. Help apps, builders, and creators go viral by giving them more distribution

2. Build new tools to help creators earn more, tell the story of onchain, and grow

3. Make core onchain experiences across social, trading, payments, and messaging

#3 Base is for ownership

We will create a powerful onchain account with seamless funding, identity, and management. We’ll continue our work on Smart Wallet to eliminate complexity for developers and users, make apps just work, and put control back in your hands.

1. New user onboarding in <60s (with funding!) without creating siloed accounts

2. Make apps just work without popups or compromising user sovereignty

3. Enable users to easily leverage their full identity and assets in a secure, private way

#4 Base is for markets

We will make Base the center of the onchain economy with highly liquid, always-on, global capital markets. The more assets and liquidity we bring to Base, the faster the entire financial world will come onchain.

1. Bring Coinbase onchain and grow the number of assets on Base

2. Support 25+ local currency stablecoins to enable every country to come onchain

3. Enable on and offramps in every country around the world

#5 Base is for everyone

We will decentralize, scale, and accelerate Base to enable everyone, everywhere to come onchain. The only way we can build a truly global economy is by making sure it’s built on a decentralized, open platform — and we are proud to do this as part of Ethereum and the Superchain.

1. Achieve Stage 1 decentralization

2. Scale Base’s blockspace capacity to 250 Mgas/s

3. Speed up blocktimes and drive down fees to deliver <1s, <1¢ transactions

These five strategic pillars are what the Base team is focused on today — and we’re building and learning every day. As we do, we’ll continue to evolve our plans and together we’ll bring the world onchain.

How we build in a based way

At the end of the day, it’s not just about what we do in 2025 — it’s also about how we do it. And in 2025, we’re going to stay based. This means:

1. Doing the right thing

2. Working hard

3. Staying optimistic

4. Pushing boundaries with creativity

5. Putting the team over the individual

If all of us can build in a based way, we’ll be able to go faster and further.

The rest is up to us

We’ve shared the Base mission and strategy and how the Base core team is contributing to make it happen. But at the end of the day, we can only succeed if all Base builders step up to make it happen. We win, together.

Are you ready to build alongside us?

Join us on X, Farcaster, and Discord to get building — and follow the Base team and Base community leaders to stay up to day with the Base economy as it grows.

Builders are creating the onchain future, around the world

With Base Around the World, we saw firsthand the real-world power of onchain tools in action, and met with incredible builders who are shaping the vision of a global onchain economy.

Here’s what we learned:

1. Momentum is global. Builders around the world are pushing the limits, and we’re here to invest in their futures. In 2025, we're doubling down on global initiatives, offering more resources, support, and office hours across time zones. We're also hiring country leads for Kenya, Argentina, and the Philippines to ensure local support is as strong as it can be. If you or someone else could be a fit, apply here.

2. Stablecoins are key. To build a global onchain economy, stablecoins are a must. They power critical use cases, from cross-border remittances to local merchant payments to small business payroll. In 2025, we believe Base’s position as the leading L2 makes it uniquely positioned as the premier onchain destination for stablecoins.

3. Local solutions, global impact. Every region has its unique challenges, but there are common themes: control over financial lives, better access to credit, and fairer economics for creators. Builders can solve these problems locally and have a global impact.

Shout-out to our community builders and Buildathon participants

Africa (Kenya)

Our first IRL stop was Kenya, where we met builders tackling social and financial challenges.  We were inspired by grassroots heroes like Maeve, who translated Base docs to Swahili.  Builders like Yele, Njoku, and Elijah passionately and generously support, elevate and mentor builders across Africa. We heard from many builders working to improve cross-border payments, IRL and P2P commerce, and microlending, all through onchain solutions.

Based Africa buildathon had the highest number of projects submitted, and we’re proud to announce 23 winners: Base Sessions, Basepay, The Unbound Project, Flexclub, RideBase, Azza Defi, AfroBase, Lendbit, Delar, Kombat, Yield, learnOnchain, Legitify, Antugrow, Health Trove, baseEastAfrica, Maisha Care, MQR Pay, PayFlip, Base Tours, Data Bud, LearNova, and Element Pay.

Southeast Asia (Bangkok, Singapore, Johor Bahru, and Manila)

After Bangalore, we landed in Bangkok for Devcon and announced the Based SEA winners during our Bangkok Meetup. We opened up Home Base for Devcon, had an incredible breakfast with women+ building on Base, and Jesse Pollak participated in a panel with Vitalik, sharing how Base now passes the walk-away test. Following Devcon, we had meetups in Singapore and closed the tour in Manila, where we participated in the YGG Gaming Summit and announced the launch of Onchain Guilds. We also made a quick stop to visit Balaji and the builders at the Network School.

We can't wait to see more creativity and new use cases come out of SEA. Check out our Based SEA buildathon winners: Cube, AgroFund, Based Chula Students, AutoBase, Onchain Buster, Magnify Cash, StreamFund, Local Coins, Kaivest, Onchain Scholars, WhiteBlue Swap, and Coinbase Smart Passport.

If you’re a builder based in Southeast Asia and want to get involved, follow Based SEA on X and Warpcast.

LatAm (Argentina, virtual)

Although we couldn’t make it to Argentina in person, we’re excited to visit for a full LatAm tour in 2025. Thanks to the Based LatAm community (powered by Odisea) for hosting the virtual buildathon and making it a success.

We’re grateful to cush, Max, chaps, Fer, Juampi, João, Simoneth, Solange, Robert, sweetman, Losi, Carlos, and many more for making the Based Latam buildathon a success and bringing people onchain to Base.

We were excited to see projects across diverse use cases in LatAm, from stablecoins to access to credit and more. Check them out: CrediTalent, Bondi Finance, CLPD Stablecoin, BOBC Stablecoin, BuildMyEvent, Sembrando El Cambio, OpenVino, and AI Agent for Coinbase Wallet.

What’s next

Across the globe, builders have told us they want continuous support — and we’re listening. In 2025 we’re planning to:

• Mentorship and education: We’re launching office hours in Africa, India, and SEA time zones to provide faster support. Plus, we’ve teamed up with RareSkills to offer an intermediate smart contract development bootcamp focused on token standards.

• Hiring: We’re looking for country leads in Kenya, the Philippines, and Argentina, along with more global roles in dev rel, marketing, and engineering. We will continue to grow our country coverage to ensure all builders get the support they need. Check out open positions here.

• Product updates: Stablecoins remain a priority in 2025. Base believes its position as the leading L2 makes it uniquely positioned as the premier onchain destination for stablecoins.. We’re also rolling out new product features to make it even easier to get onchain.

The Base Around the World tour was a journey we’ll never forget, and we’re excited for what’s ahead. Builders, we’ll see you in 2025.

Building towards decentralization

From the beginning of Base, we have championed the belief that creating an open, global onchain economy is only possible on a decentralized platform. This is why Base is:

• Built on Ethereum — the most secure and decentralized L1.

• Built on Optimism’s open-source OP Stack — an open-source public good that serves as the foundation for a Superchain of L2s that will share interoperability, security, and governance.

• Committed to the Law of Chains with Optimism, which includes a commitment to neutrality, a decentralized security model, ecosystem protections, and community governance principles.

• Upholding the Base Neutrality Principles, including user autonomy, unbiased transaction sequencing, discretion with non-public data, and unrestricted withdrawals.

We’re laser-focused on making continuous advancements towards full decentralization. This is why, today, we’re taking the next important step in decentralizing the network: fault proofs are now live on Base Mainnet.

What fault proofs mean for Base

Vitalik’s decentralization framework lays out a path for Layer-2 rollups on Ethereum, like Base, to progressively and safely decentralize. Fault proofs are an essential component of going from Stage 0, in which a rollup has “full training wheels,” to Stage 1, which has “limited training wheels”.

This year, the Base core team collaborated closely with Optimism to bring the OP Stack Fault Proof System to Base. This enables a decentralized approach to proposing and validating L2 state, and paves the way towards more community participation.

Fault proofs have two important capabilities to improve decentralization:

• Permissionless proposals: Fault proofs help validate the state of Base in a decentralized way, allowing any participant to propose claims about the overall state of the chain, and the legitimacy of the transactions on it. This removes reliance on a central party to prove state. Permissionless output proposals go beyond what is required for Stage 1 decentralization.

• Permissionless challenges: If a faulty or fraudulent claim is made (e.g. a malicious attempt to withdraw ETH from the bridge), anyone can challenge it within 3.5 days by running the open-source challenger software included in the OP Stack. Participants who successfully challenge a claim receive the bonds of the invalid claim, creating an economic incentive to help secure the network. This fosters community-driven accountability and control, reducing the need to trust a centralized entity for state verification. With the Fault Proof System, the presence of even a single honest challenger ensures the network will remain secure. To maintain this safeguard, the Base team will operate a challenger continuously.

Together, these changes significantly increase the decentralization of Base and allow anyone to permissionlessly move their funds from Base L2 to Ethereum L1 without relying on any centralized actors.

Next up: Stage 1 decentralization and beyond

Fault proofs are a big step towards Stage 1 decentralization, but we have one more milestone to hit to get there. Today, smart contract upgrades on Base are reviewed and approved by several contributors from the Base and Optimism teams.

Getting to Stage 1 means expanding this set of approvers to a broader, decentralized group of stakeholders — a “security council” — ensuring that Base protocol upgrades are managed without centralized control. Base is on track to complete this final step and achieve Stage 1 decentralization in the coming months.

Looking towards 2025, we’re excited to continue progressing towards full decentralization by taking steps towards Stage 2. Our biggest priority is to support the development of multiple fault proof implementations, such as our recent contributions to standardize L2 state validation and improve compatibility of fault proofs with new execution clients.

With fault proofs now live, we’re excited to continue building on the Base, Superchain, and Ethereum vision of a more decentralized, better internet that is accessible to all.

Building Base with a security-first approach

From day one, Base has been built with a security-first approach — combining Coinbase's enterprise-grade practices with an open-source codebase. At the chain level:

• Base is built on the secure, open-source OP Stack with Optimism, benefiting from extensive audits and community security efforts.

• Coinbase's Protocol Security team thoroughly audited Base, enhancing security and ensuring no critical vulnerabilities before mainnet launch.

• Before mainnet launch, Base engaged over 100 security researchers in a public audit contest, strengthening Base's security through broad community input.

To bring the next billion users onchain, we’re now looking to empower builders with the tools they need to build secure, reliable apps and protocols for their users. A critical component of this is smart contract monitoring, enabling builders to detect potential threats to their app or protocol and take action. But onchain monitoring is expensive, time-consuming, and difficult for builders to set up.

Now, we're taking a major step towards this by offering access to free smart contract monitoring, detection, and analytics for every app or protocol on Base by partnering with Hexagate.

Empowering builders on Base with advanced security tools

For the past year, the Base core team has leveraged Hexagate’s solutions to improve security on Base — using its threat detection ML models, invariant monitoring, and risk intelligence to proactively enhance Base’s security.

These solutions monitor foundational assets, like cbBTC, as well as sophisticated smart contract systems like fault proofs, to deliver comprehensive, real-time insights. Earlier this year, we successfully completed a SEAL Wargame Simulation using the Hexagate platform to stress test our security protocols against incidents.

Through our collaboration with Hexagate, every builder on Base now has free access to tools that enable early threat detection and proactive risk mitigation.

How it works

Builders on Base can now use Hexagate’s enterprise-grade platform to secure their apps and protocols with:

• Hexagate Ecosystem Tier: Real-time, ML-based threat monitoring for up to 10 contracts on Base — plus 5 custom monitors for known threats for these contracts for free.

• Real-Time Alerts: Immediate notifications that can be forwarded through channels like Slack, Telegram, or email.

• Guidance and Support: Documentation and tutorials on setting up monitors, triage alerts, and responding to incidents.

Base is committed to building in the open, including public retrospectives to share learnings when issues arise.

On 09/21/2024 at 15:14 UTC, Base Mainnet experienced a 17 minute block building outage. The integrity of the chain was not affected, all funds on Base were safe, and block production resumed after we mitigated the incident. This retrospective dives into the root cause, the impact, how we mitigated, and what we plan to improve moving forward.

The root cause of the block building outage was a misconfiguration on our sequencer cluster. When the current block producer became unhealthy, it was unable to successfully start block building on another instance. The incident was mitigated by manually starting block production on a correctly configured instance.

Impact

Block Production

No blocks were produced for 17 minutes, beginning at 15:14 UTC. Blocks 20071146 to 20071691 contain no user transactions, as they were created by the protocol after sequencing resumed.

Transaction Processing

Transactions are submitted to Base through the `eth_sendRawTransaction` RPC call, which places them in the mempool. During the incident, the mempool instances continued to function correctly. However, fewer transactions were submitted in that time frame, which can be seen in the graph below.

There was an immediate drop in both successful and failed `eth_sendRawTransaction` requests after the outage started, followed by a slow rise in failed requests. Our current hypothesis is that less transactions were submitted because applications were impaired by the halt in block production.

Once block production resumed, many of the transactions that were submitted during the incident were included in the blocks immediately following 20071691.

Root Cause

Background

Over the past year, Base has designed and built op-conductor to improve the reliability of block production. Our goal with building op-conductor is to increase the overall availability of the system, with a target of achieving 99.99% availability. Prior to op-conductor, any failure of the sequencer would result in an outage. op-conductor enables us to operate multiple sequencers and upon a failure start block production on a healthy instance.

On 9/20/2024, we migrated block production from the single sequencer to the op-conductor cluster. However the op-conductor instances were in a misconfigured state, where op-node was not submitting new unsafe block payloads to op-conductor.

Trigger

On 9/21/2024 at 15:14 UTC, the currently active sequencer experienced delays in block production. op-conductor correctly detected the issue and began the process to transfer leadership to another instance. As part of the leadership transfer, op-conductor stopped the local op-node from building blocks.

Due to the misconfiguration, the new block producer was unable to start production as the start operation requires the unsafe payload from op-conductor, which the previous leader did not write. This caused the cluster to enter a state in which no instance was able to become an active block producer.

Below is a log snippet containing one sample of a failed leadership transfer:

Mitigation

The incident was mitigated by reverting to the single sequencer topology while the op-conductor cluster configuration was fixed.

What we’re fixing going forward

• We implemented a bidirectional handshake between op-node and op-conductor at startup to ensure proper communication configuration.

• Improve our internal configuration management process to prevent and detect misconfigurations.

Base’s mission is to increase innovation, creativity, and freedom, and we know we can't achieve this mission alone. This fall, we’re excited to meet with builders around the world.

To kick things off, we’re launching Base Around the World: a series of regional buildathons in Africa, India, Southeast Asia, and Latin America. Following the buildathons, Jesse Pollak and the Base team will meet in person with builders in Nairobi, Bangalore, Bangkok, Singapore, and Manila, and virtually in Buenos Aires. Dates for each event will be announced soon.

We’re focused on these regions for two main reasons:

1. We’re seeing tremendous energy: Today, 74% of onchain builders live outside the US and these four regions are seeing some of the fastest growth in onchain adoption. In each, there are growing onchain use cases and talented builders who are solving hard problems. We want to connect, find opportunities to build together, and empower them with resources and support.

2. We can use onchain to solve problems in local contexts: Every community has different challenges and contexts where onchain technology can be useful. Building a better internet starts by local communities solving local challenges, in ways just now becoming possible. That’s why we are taking a local focus for these buildathons. We want to zero in on the use cases that will bring people benefits in their everyday lives.

Base Around the World: Africa, India, Latin America, and Southeast Asia

The buildathons will run in parallel from September 27 to October 13. There is one simple prompt: Build an onchain app that solves a challenge in your community, or use existing onchain tools to create real-world impact in your community by bringing them onchain.

If you’re looking for ideas, here are a few places to start:

• Help people come together, connect, and collaborate more easily — onchain or IRL

• Unlock access to social and educational resources

• Build tools that provide easier access to the onchain economy

• Create localized social or e-commerce apps

• Create platforms that empower creators to share their work (or, if you're a creator yourself, share your own)

• Make a blog, write a blog post, create a YouTube or TikTok video, or other content showing how you're making an impact and bringing your community onchain

Registration is now open on Devfolio:

• Based Africa

• Based Southeast Asia

• Based LatAm

• Based India

We’re excited to co-present the buildathons with local builders who are already driving impact in their communities.

We built

In June, we hosted the Onchain Summer Buildathon with Stripe, Shopify, Zora, Farcaster, Aerodrome, Fleek, Thirdweb, Nouns, Synthetix, and Bountycaster — resulting in the largest-ever onchain hackathon with:

• 7,500+ participating builders from around the world

• 1,250+ final projects submitted

• 300+ ETH in prizes for builders

• $200k+ USDC in bounties via Bountycaster

The Buildathon showcased how diverse the onchain economy is, with builders creating innovative projects across commerce, payments, gaming, creator, social, and more—including onchain checkout systems, interactive content feeds, social gaming experiences, new DeFi protocols, and more. For example, For The Children: July 2024 was awarded 2.22 ETH for bringing together 40+ artists and 30+ communities to sponsor and sign a collaborative digital artwork to raise money for children in the Dominican Republic.

We created

Throughout Onchain Summer, thousands of projects brought the world onchain through dead-simple, built-for-everyone onchain experiences spanning art, music, sports, gaming, beauty, food, loyalty, advocacy, in-person events, and so much more — with a variety of activations including:

• Atari brought arcade classics like Asteroids and Breakout onchain — distributing 40+ ETH in mint proceeds to the developers, artists, and builders behind each game.

• Doodles launched Doodlesᵗᵛ to give fans first access to music releases by Pharrell, limited-edition collectibles, and the premiere of ‘Dullsville and the Doodleverse’ — featuring artists like Lil Wayne, Lil Yachty, Coi Leray, Swae Lee, and Kyle Rich.

• Team Liquid launched a gaming tournament series with Community Gaming — distributing $20K USDC in rewards, paid directly onchain.

• Coinbase teamed up with renowned artist Daniel Arsham to celebrate 50 years of USA Basketball — with four digital collectibles representing the seasons of hard work required to build a championship team.

• Daylight debuted with an edition that gives holders perks and discounts — decentralizing the grid and bringing the energy industry onchain to improve access to cheap, reliable power for everyone.

With thousands of participating projects across 3 months, Onchain Summer resulted in:

• $5M+ in mint revenue for builders, creators, and projects

• 2M+ unique wallets participating in onchain experiences on Base, and 8x more than last Onchain Summer

• 24M+ onchain assets minted

We connected

Last August, Base made its debut from an unlikely launchpad: a remote Starlink setup in the mountains of Idyllwild, California. We went live surrounded by the energy of onchain creators, visionaries, and the mountains.

One year later, we came full circle by bringing BaseCamp to Idyllwild. This summer we gathered the Base community together to connect, look towards the onchain future, and work together to accelerate progress.

Designed to ignite the builder spirit, BaseCamp consisted of vision-setting, lightning talks, live performances, interactive art-making, delicious food, and bonding activities — centered around the BaseCamp Summit with talks from guests including the Coinbase team, ecosystem builders, and a special virtual appearance from Vitalik Buterin, co-founder of Ethereum. In case you missed it, watch the Basecamp Summit to learn about Coinbase’s vision to bring the world onchain.

We onboarded

This summer, we brought local businesses onchain with Coffee Days and onboarded a dozen coffee shops around the world to onchain payments. As part of Onchain Summer, anyone could mint a coffee NFT to sponsor coffee at one of the participating shops. Then, customers at those shops could get a free cup of coffee by getting onchain via Coinbase Wallet. The first cup of coffee is free, and participating shops also offer $1 coffee all summer long to anyone paying with USDC on Base.

Coffee Days brought onchain payments into the real world and showed customers and businesses how crypto can simplify and enhance everyday transactions. Paying for coffee onchain is fast and easy, and helps local businesses save money on fees. Sending USDC with Coinbase Wallet means instant settlement and no middlemen fees.

What’s next: Onchain Daily

The sun is setting for Onchain Summer, but we’re excited to continue to spotlight onchain builders and creators year-round through Onchain Daily — our daily showcase of onchain creativity and innovation in the Base ecosystem. Coinbase Wallet will continue being a destination for people to discover onchain innovation — with new projects surfaced each day and features on Base’s X and Warpcast channels.

If you’re a creator, builder, or brand, we want to share what you’re building with millions of people across the world. Submit your apps, games, art, music, and dreams to the Onchain Registry for the chance to be featured across the Onchain Content Network. And if you want to create a feed or incorporate Onchain Daily content into your existing platform, learn how to integrate the Onchain Registry API.

Now, let’s keep bringing the world onchain

Onchain is better than it’s ever been before — with sub-cent transaction fees on Base, smart wallets to onboard people instantly, powerful social graphs that let you enter onchain apps with a fully-fledged identity, and so much more that makes it accessible for builders and users alike.

So keep building, creating, connecting, and dreaming.

Because summer never ends.

We’re showcasing our progress in this new blog series, Scaling Base, where we’ll share updates and our plan as we bring a billion people onchain. In this installment, we’re sharing our approach to increase data availability capacity as we look towards the integration of PeerDAS in the upcoming Pectra upgrade.

Scaling Base since launch

Ethereum introduced EIP-4844 in March of this year—an upgrade that resulted in a 100x reduction in L2 gas fees by decoupling them from Ethereum Mainnet fees. This decoupling is what allows the combined network to scale: If a Layer 2 gets congested, it can act independently to increase its target capacity and bring transaction fees back down.

As a result, we’ve scaled Base’s throughput by 4x since launching it a year ago, increasing the gas target per block from 2.5 Mgas/s to 10 Mgas/s to keep fees under one cent as activity grows. This has only been possible due to a huge amount of hard work from both the Base core team and the entire ecosystem of builders scaling the OP Stack, Ethereum clients, and the EVM.

Where we go from here: 1 Mgas/s increase per week

A few months ago, we set an ambitious goal: achieving 1 Ggas/s capacity for Base. We know that the journey to get there will require a lot of hard work and collaboration across many teams. Taking a step back, we realized that both for our internal team and for the broader ecosystem, the more predictability we can provide in our scaling journey, the easier it will be to plan and coordinate the necessary work.

To provide this clarity, we’re shifting the way we think about scaling Base: we are going to commit to an ongoing rate of gas target increase, then do the work to ensure we can achieve that increase by scaling across all the key properties.

To start, we are publicly committing to increasing the Base gas target by 1 Mgas/s each week, starting in late September. These increases will be subject to continued monitoring and testing—and if we need to change plans, we’ll communicate our key learnings and changes clearly. As we continue to scale the underlying infrastructure and build confidence, our goal is to then grow the rate of increase (e.g. 2 Mgas/s per week) to accelerate our progress towards 1 Ggas/s.

If you’re building on Base, or helping scale the infrastructure powering Base, our hope is that you can use this guidance as a north star for coordinating and planning your efforts. And if you have feedback on our approach, we’d love to hear it!

Pectra and PeerDAS

As Base continues to scale, we’re looking towards the Ethereum community to integrate the necessary mainnet upgrades to increase L1 data availability—ensuring that L2s can continue to bring the next billion users onchain.

For the past two years, we have collaborated with the Ethereum core developer community on this mission, beginning with EIP-4844. This upgrade—co-led by the Base team, OP Labs, and Ethereum Core Developers—significantly reduced costs on Base and other L2s by introducing blob space and providing a fixed amount of blob space for data availability.

But with increasing demand, our projections show that the current limits will not meet Base’s requirements in the coming year. This is where PeerDAS comes in.

PeerDAS (Peer Data Availability Sampling), a protocol change in the upcoming Pectra hard fork, addresses this by increasing total blob capacity without requiring every node to download every blob. It ensures Ethereum nodes can access all blob data while only downloading a fraction, significantly reducing network bandwidth requirements and unlocking substantial data availability capacity.

The Base core team has been actively working towards preparing PeerDAS for inclusion in the Pectra upgrade:

• We’re collaborating with ethPandaOps to conduct network analysis on PeerDAS devnets, providing essential data to inform recommendations.

• We’re contributing to the implementation within Prysm which is being used to drive the initial analyses.

PeerDAS blob capacity

Alongside these contributions, we’re advocating for a significant increase in blob capacity alongside activation of PeerDAS. This is crucial for scaling efforts, allowing more data to be processed without overloading individual nodes.

Any bandwidth-affecting protocol change should naturally face developer scrutiny, given the risks of introducing network instability and networking related denial-of-service attacks. Due to the complexity of PeerDAS, some have advocated for its inclusion while keeping the blob capacity unchanged at first. This approach would push any increase in data availability capacity to a subsequent upgrade, which could be many months (if not a year) after Pectra activates in 2025.

While the final details of PeerDAS are still being discussed, we believe its architecture allows for existing bandwidth-limited stakers to safely participate. Additionally, EIP-7251, also planned for Pectra, should reduce attestation and sync_committee p2p traffic, the main consumer of node bandwidth.

Imposing a higher minimum price for blob data

One argument against a capacity increase is that L1 nodes need to be fairly compensated for the compute, storage and bandwidth required for providing data availability. When demand for blobs is below target, prices fall to the bare minimum: 1 wei per byte of blob data. Demand exceeding target capacity allows for a market-based pricing mechanism to kick in, resulting in better recovery of the costs incurred on L1 nodes.

We think that addressing this problem by constraining DA capacity is a step in the wrong direction; instead, we suggest a different approach, ensuring a healthy market for blob space so that the network is fairly compensated while keeping it unconstrained. Some potential solutions are to raise minimum blob fees or implement a different fee mechanism for blob data.

Increasing the target to achieve positive-sum scaling

Post EIP-4844, L2 transaction fees will remain decoupled from Ethereum Mainnet fees as long as the average demand for blobs stays below the target (currently 3 per block).

So far, we've only seen a few instances where blob demand has exceeded this target for extended periods. Some may view below-target blob demand as a reason to proceed conservatively. However, with Base’s scaling plan and L2 demand growing, we expect the demand to consistently meet or exceed capacity within the coming months. Exceeding the target would end the decoupling of transaction fees—disallowing L2s to independently increase capacity and maintain low fees.

When data availability hits target capacity, scaling becomes a zero-sum game—one L2's increased throughput would negatively impact another. We aim to create a positive sum scaling environment. Implementing PeerDAS and increasing the blob count are crucial steps to achieving this goal.

L2 protocol improvements

L1 data availability can be indirectly scaled through L2 protocol improvements that reduce the required data. The OP Stack already features innovations like span batch data layout and Brotli compression from the Fjord upgrade, which improved Base’s data compression ratio by 25%. Future enhancements include stateful compression and aggregatable signatures for L2 transactions and UserOps. These improvements, while helpful, are the icing on the cake. Ultimately, the data availability capacity of mainnet must grow in order to support a healthy scaling roadmap.

Looking forward

As Ethereum continues to grow, any increase in data availability capacity will eventually be absorbed by organic demand. While a market-based pricing regime for data availability is inevitable, maintaining decoupled fees for as long as possible will allow Ethereum to scale more rapidly to its full potential.

As more and more people come onchain, wallet addresses aren't cutting it as a way to connect with each other. These long strings of numbers and text add friction to transactions, make it difficult for builders to spot superfans of their apps, and turn finding the right collaborators into a needle-in-a-haystack hunt.

Basenames are an onchain identity created by and for builders, solving some of the hardest problems that Base builders face every day: finding others to build with, getting access to the best resources, and enabling easy experiences for everyday people who use the apps they build.

This feature will be available for all Base profiles soon.

A new chapter for onchain identity on Base

In the early days of Base, Base Name Service (BNS) was started as an independent project by a team of builders, including Itgel Ganbold (aka JackJack), Sabit Bazar, and Gabit Bazar, at ETHDenver 2023. With the launch of Basenames, the BNS team has made the thoughtful decision to wind down their service to ensure a unified name service and onchain identity experience for everyone on Base.

We’re incredibly grateful to the BNS team for their support of Basenames, and for being early builders in the Base ecosystem. As a thank you, all BNS name holders are eligible for a special discount on Basenames when registering with the same wallet that contains your BNS name.

A better onchain experience to bring the next billion onchain

We can’t wait to see how you use Basenames to enhance your onchain journey and build a vibrant ecosystem on Base. If you’re a builder looking to integrate Basenames into your app, OnchainKit is the easiest way to get started.

Shout-outs

We’re grateful to our production partner Devfolio for helping steward the hackathon, and our track sponsors Stripe, Shopify, Farcaster, Zora, Fleek, Nouns, Thirdweb, Aerodrome, and Synthetix for the mentorship, commitment, and bounties they provided.

Bountycaster helped bring even more creativity and use cases onchain by running a decentralized, community-sponsored track alongside the Buildathon.

Above all, we’re grateful for everyone who built remarkable onchain experiences for the world.

We can’t wait to continue building with all of you.

Submit your apps, games, art, music, and dreams to the Onchain Registry — a community-driven database of projects — for the chance to be featured across our new Onchain Content Network: Coinbase, Coinbase Wallet, Cymbal, Daylight, Floor, Forage, Layer3, Magic Eden, Mintify, OpenSea, Rainbow Wallet, and Roam.

Together, our goal is to spotlight more of the builders and creators that are bringing the world onchain.

Submit your project → Get distribution

Creating a global economy that fosters innovation, creativity, and freedom cannot be done alone. That’s why the Onchain Content Network is crucial to our mission — bringing together a collection of the industry's best known and most loved platforms, generating more distribution for builders, and creating destinations for everyone to discover onchain innovation.

From the largest NFT marketplaces to the most active questing platforms, these partners will feature selected projects from the Onchain Registry to the millions of people that visit them every day — with dedicated feeds that surface projects directly from onchain builders and creators.

Let’s bring the world onchain together

Whether you’re a builder, creator, or brand, we want to help you by distributing your project as far and wide as possible via the Onchain Content Network. Here’s what we’re looking for:

• Do something that’s never been done before: Create captivating onchain experiences. The more innovative, the better.

• Keep it simple: Bringing a billion people onchain requires onboarding that feels like a warm welcome. Experiences should be frictionless for new users.

• Make something accessible to everyone: Whether it’s a game, social app, piece of art, or commerce flow, Onchain Summer is for everyone. Keep it low-cost and easy for anyone to use.

If you’re working on something that aligns with this vision, we invite you to share it with us. Submit your project to the Onchain Registry.

And if you want to create a feed or incorporate Onchain Summer content into your existing platform, learn how to integrate the Onchain Registry API.

Base launched with a vision to decentralize over time, and decentralization and scalability are some of our top priorities.

We’re now taking a step towards the next stage of decentralization: fault proofs are live on Base Sepolia testnet. Fault proofs enable anyone to make or challenge a proposal about the state of an L2 in a permissionless way. Today’s launch paves the way for bringing fault proofs securely to mainnet, and completing other milestones to reach Stage 1 Decentralization.

Fault proofs: A foundational step towards decentralization

Fault proofs improve decentralization in two major ways:

• Permissionless output proposals: In an L2 without fault proofs, only the centralized proposer (controlled by the chain operators) can create and submit claims about the state of the L2 to Ethereum. With fault proofs, anyone can make claims about an L2’s state instead of relying on a central party.

• Permissionless challenges to output proposals: If someone makes a faulty or fraudulent claim, anyone can challenge it.

Fault proofs are a foundational step towards more community-driven accountability and control, which reduces the need to place trust in a centralized party for state verification. As such, they are a key piece in a rollup’s progression towards decentralization.

Many rollups launch at Stage 0 (based on Vitalik’s definition) to balance security with decentralization, ensuring sufficient controls are in place as they grow and strengthen their infrastructure and ecosystems.

• Stage 0, or “full training wheels,” is a stage where all rollup transactions are posted on the L2, and the validity checks of these transactions are done by the chain’s operators. Therefore, state verification is centralized and dependent upon the chain operators.

• In Stage 1 decentralization, or “limited training wheels,” the chain state is verified with fault proofs but there is an override mechanism that can act in the event of a bug. The override mechanism requires consensus from both chain operators and a designated number of external stakeholders, which reduces the dependence on chain operators alone.

• In Stage 2 decentralization, changes to the L2 state only take place if a bug is uncovered, and any contract upgrades are subject to a 30 day delay (allowing those who disagree with an upgrade time to withdraw funds).

We’re super excited about the momentum in the L2 ecosystem towards decentralization (with most recently OP Mainnet reaching Stage 1). The evolution to Stage 1 highlights the importance of fault proofs in enhancing the transparency, security, and decentralization of Base by allowing broader participation in state verification and dispute resolution.

Getting to Stage 1 Decentralization

Launching fault proofs on Sepolia testnet provides an environment to run additional testing to help bring fault proofs to mainnet securely.

The other important step for Base to reach Stage 1 decentralization is to add the Security Council to our contract upgrade keys. This process further decentralizes the contract upgrade approval process we have today, extending it to a decentralized group of stakeholders beyond just Optimism and Base.

It also aligns us more closely with the Superchain vision: once this step is complete, Base can only make contract upgrades with actions taken by the Optimism Security Council, which only takes actions approved by Optimism Governance. We believe that the Optimism Security Council has the right controls and incentive structure in place to support the growth of the entire Superchain ecosystem and to continue building towards the vision of scaling Ethereum.

What’s next

Base’s commitment to decentralization and stability is a top priority, and this is a major next step in our decentralization journey. We’re excited to continue building on the Superchain vision of a more decentralized, better internet that’s accessible to everyone.

Back to where it all began

Last August, Base made its mainnet debut from an unlikely launchpad: a remote Starlink setup in the mountains of Idyllwild, California during FWB FEST 2023. Why'd we choose to go live from there? We wanted to be surrounded by the energy of onchain creators, visionaries, and the mountains underneath our feet.

Now, one year later, we're coming full circle by bringing BaseCamp to the same symbolic space. For two days in Idyllwild, we’re bringing the Base community together to connect, look towards our onchain future, and work together to accelerate progress.

Building the onchain future, offgrid

BaseCamp celebrates the projects and people at the forefront of building onchain. At its heart, this is a time for the Base community to connect, share ideas, and forge new collaborations that propel us toward a future where more people participate in a global, onchain economy.

The BaseCamp experience is designed to ignite the builder spirit through vision-setting, lightning talks, live performances, interactive art-making, delicious food, and bonding activities.

BaseCamp precedes FWB FEST 2024 and takes place from Wednesday July 31, to Thursday, August 1, including a welcome mixer and 1-day summit. Attendance at BaseCamp will include:

• A fully hosted experience, with complimentary lodging and dining. All we ask is that you cover your own travel to LAX or Palm Springs airport.

• A complimentary ticket to FWB FEST, so you can experience the broader onchain cultural context that Base was launched in.

“Our deeply held belief at FWB is that we are in a reciprocal relationship with our internet: as we build it, it in turn shapes us. FWB FEST provides a container for Base founders and builders to not only spend critical time IRL, but to integrate culture into crypto infrastructure and consumer products. This positive feedback loop will only build a better internet and bring more people into the onchain arena. BASECAMP at FWB FEST is a validation of our thesis that culture drives adoption of emerging tech.”

– Greg Bresnitz, CEO of FWB

Want to be a part of BaseCamp?

Because of the intimate setting, for its first year, BaseCamp will be by invitation or application only, with plans to broaden to more people in future years. Apply now to join us in Idyllwild this August. Note that spots are limited, and we will be prioritizing those who have previously received a Base grant or contributed to the Base ecosystem in a meaningful way. Please share what you’ve contributed and what you hope to get out of attending BaseCamp. Learn more and apply here.

Even if you can’t make it, we invite you to build with us during Onchain Summer.

To kickoff Onchain Summer, we’re sponsoring one of the largest global online hackathons ever, dedicated to bringing the world onchain. From May 31st - June 30th we want you to show us what’s possible across payments, commerce, gaming, social, and more.

200 ETH across 8 sponsored tracks and a bonus pool

The Buildathon (managed by Devfolio) has eight tracks covering some of the fastest-growing onchain use cases today. Each track offers 20 ETH in total rewards, with 2-10 winning teams selected from each track. We’re looking for experiences that make it easy for anyone to get onchain in the following categories:

1. PAYMENTS with Stripe: Build easy to use consumer payment experiences.

2. DISCOVERY with Fleek: Develop compelling apps using the Onchain Summer Registry that help people find things to do onchain.

3. CREATOR with Zora: Create new and imaginative ways for onchain creativity to thrive with projects that help people create, discover, curate, and collect.

4. SOCIAL with Farcaster: Bring people together with social experiences that harness the potential of being onchain.

5. GAMING with thirdweb: Build onchain games with a focus on fun and mainstream adoption.

6. COMMERCE with Shopify: Create compelling commerce experiences for merchants with URL<> IRL tie-ins, like affiliate or loyalty programs that come alive onchain.

7. UNPLUGGED with Nouns:  Make a real world impact by mixing the IRL<>URL, with a focus on community engagement and real-world impact.

8. TRADING with Aerodrome and Synthetix: Develop innovative trading and investing experiences like DeFi primitives with app interoperability.

In addition to the track rewards, we’re adding a bonus pool of 40 ETH for builders using the following tools to superpower their onchain apps: Coinbase Smart Wallet, Coinbase Verifications, Coinbase Paymaster, and OnchainKit.

Building a global onchain economy

By simplifying onchain transactions and making them accessible globally, we're unlocking the financial potential of the internet. Join us in bringing the next billion users onchain by making it easier to onramp.

Last summer, we came together with builders, brands, artists, and creators to showcase what's possible onchain. For 23 days, we celebrated the launch of Base’s mainnet with onchain music, gaming, advocacy, and art, from builders like Coca-Cola, Blackbird, Zora, FWB, Parallel, and a roster of others all working together to build an onchain future.

Onchain is already powering today’s financial system updates and Onchain Summer is an annual effort that brings us closer to the next chapter – where onchain is the next online. We’re calling on creators and builders everywhere to shape the next era of the internet and help bring the next billion users onchain by showing what’s possible.

It’s time for Onchain Summer II.

This year we’re inviting everyone to build all summer long, starting on June 3 and ending in August. To help enable this, Base and our ecosystem partners are offering over 600 ETH ($2 million) in prizes, grants, and gas credits.

Onchain Summer will kick off with a month-long online hackathon hosted by Base and partners. Then, during July and August, Coinbase will showcase daily experiences that make coming onchain easier and more fun than ever.

Are you ready to get building? Here’s the type of experiences we’re looking for:

• Do something that’s never been done before: Create captivating onchain experiences; the more innovative, the better.

• Make something accessible to everyone: Whether it’s a game, social app, piece of art, or commerce flow, Onchain Summer is for everyone. Keep it low-cost and easy for anyone to use.

• Keep it simple: Bringing a billion people onchain requires onboarding that feels like a warm welcome. Experiences should be frictionless for new users.

The best projects built during Onchain Summer will have the opportunity to reach millions of people, with the support of Base, Coinbase, and everyone else bringing the world onchain. Coinbase will offer an Onchain Summer destination, where builders and creators can launch their work, sell merchandise, distribute prizes and much more. If you’re working on something that matches this vision, we invite you to share it with us. Submit your project to participate in Onchain Summer.

Over 600 ETH worth of rewards for builders and creators

We want everyone to bring their creativity onchain this summer. Here’s how we’re helping you build and create:

• Onchain Summer Buildathon is a month-long global online hackathon through the month of June. Keep an eye out for more details in the coming weeks about the categories and how you can participate.

• Gas Credits will be available for anyone looking to sponsor transactions and offer gasless experiences. Claim 0.25 ETH by signing up for Coinbase Developer Platform (and you can apply for more here). You can also access gas credits through Safe, Alchemy, Biconomy, Syndicate, Pimlico, ZeroDev, and Stackup.

• Builder Grants are small retroactive grants for builders with early ideas or initial prototypes. In addition to Base grants, other ecosystem partners will be rewarding builders and creators throughout Onchain Summer, including Rounds and Optimism.

Tools to help you build

One of the biggest barriers to growing onchain adoption is the complexity of the user onboarding experience. Base is collaborating with teams across the ecosystem, including Coinbase, to enable tools for Onchain Summer builders.

• Easier Wallet Onboarding: Coinbase’s new smart wallet recently launched on Base Sepolia testnet for devs to start building with it, and will be available on mainnet for consumers later this quarter. Smart wallet allows users to create a new wallet instantly for any onchain app using just a passkey – no app downloads, extensions, or seed phrases required. We’re also excited by onchain user onboarding experiences from Dynamic and Privy.

• Seamless User Experiences: As developers build with account abstraction standards like EIP-4337, they need access to best in class tools for abstracting gas and enabling users to more easily transact. Builders looking to get started with account-abstracted experiences can use infrastructure from Alchemy, Biconomy, Coinbase Developer Platform, Pimlico, Safe, Sequence, Stackup, or ZeroDev. And if you’re new to building onchain apps, check out the open-source Build Onchain Apps Toolkit.
