The OP Stack is becoming the standard. Standards win because they compound. More OP Stack chains mean more experiments, faster iteration, and unstoppable momentum. The OP Stack powers more L2 transactions than any other framework - 69.9% of all L2 transaction fees are on the Superchain, as is 49% of L2 TVL. From Base, Unichain, and World Chain to Soneium, OP Mainnet, Celo, and Ink, the most serious teams are building on Optimism’s open and modular stack. Together, they are laying the foundation for the Superchain by contributing a portion of their revenue to the Optimism Collective and helping grow a thriving ecosystem of builders.

The OP Stack was built to support innovation. It gives teams the flexibility to try new proof systems, customize data availability, and explore alternative approaches to governance and economics. That openness is by design. We believe the fastest way to innovate is by building in the open, making our work free to use, fork, and improve. As a result, we are seeing an incredible range of teams use the OP Stack in different ways—from consumer-focused apps to ZK research to institutional infrastructure. Through the over 850 million OP tokens allocated towards ecosystem support through Retro Funding, the Optimism Collective has supported teams like O(1), Risc0, and Succinct to bring that vision closer to reality. Because of efforts like these, the OP Stack became ZK-ready in early 2023. Although these systems are still maturing, they are already pushing the possibilities of the OP Stack in exciting directions.

Today, Conduit is introducing a new path for teams to launch OP Stack chains that connect to the AggLayer. It confirms what we’re already seeing today: The OP Stack is becoming the default foundation for new chains, regardless of the ecosystem’s go-to-market approach. While these new models may appeal to teams looking to experiment with new architectures, the Superchain remains focused on building Stage 1 rollups with shared upgrades, credible neutrality, and interoperability. As innovation with the OP Stack continues across the ecosystem, we look forward to upstreaming the most promising advances, like ZK proofs, into the Superchain over time.

The Superchain remains the most credible and battle-tested path for teams building serious, long-term chain solutions. At the same time, continued open experimentation across the OP Stack strengthens the broader ecosystem. Together, this creates a powerful dynamic that is driving the OP Stack to become the shared standard for scaling Ethereum.

While the OP Stack has made it easier than ever to launch new chains, we agree with what many in the ecosystem are saying — the real opportunity right now is not just more chains, but more great apps. Beyond just more ways to launch an OP Stack chain, we’re excited for apps that use crypto as a tool to solve real-world problems, not just apps built for crypto. With native interoperability, shared liquidity, and seamless user experiences across chains, the Superchain will unlock new kinds of applications that simply aren't possible anywhere else.

That’s where we believe the next wave of value will come from, and we’re focused on supporting the people who are ready to innovate.

Nerdsniped on the Superchain? Come help build it.

• Retro Funding Onchain Builders rewards projects that drive cross-chain asset transfers, enabled through interop, by growing the Superchain across eligible OP Chains. Dev Tooling rewards toolchain software, such as compilers, libraries and debuggers, that support builders in developing onchain applications on the Superchain.

• Build interoperable apps on Superchain devnet

• Building a Superchain app? Apply for a grant to cover your audit

Throughout the summer, we’ll unveil new Superchain native apps, showcase the interop set in action, and launch new rewards opportunities for developers. The pace of innovation is accelerating, and the Superchain is where it’s all coming together.
