Why Migrate to the Superchain?

NFT collections are more than just a set of digital assets — they’re a vibrant community.

Digital collectibles consistently engage new collectors and fans, who collectively contribute towards a shared vision. This is how NFT communities thrive, but once-thriving communities are seeing a slowdown in activity and engagement. It's becoming harder to onboard new members, and even the most dedicated supporters are struggling to stay involved with rising gas costs making it impractical to engage further.

By layering up your NFT collection to the Superchain, you can:

1. Supercharge Trading Activity: By layering up to the Superchain, you'll tap into a network with significantly lower transaction fees, enabling your community to trade, collect, and engage with your NFTs like never before. No more prohibitive gas costs dampening your transaction volume.

2. Expand Your Collector Base: The Superchain has become the forefront of NFT activity. It’s a thriving ecosystem of users, with new collectors joining every day thanks to seamless onboarding from platforms like Coinbase and Zora. By layering up, you'll gain exposure to this rapidly growing audience, forging new connections and attracting a diverse range of collectors to your community.

3. Grow Your Impact & Reputation: As an early adopter on the Superchain, your collection will be well-positioned to benefit from upcoming retroactive public goods initiatives led by Optimism. By contributing to the growth and vitality of the ecosystem, you'll have the chance to not only be rewarded financially but also cement your reputation as a leader in Superchain.

4. Strengthen Community: The Superchain isn't just about enhancing your collection's features – it's about providing your community with a powerful new space to connect, collaborate, and grow together. Farcaster, Zora, Base, and OP are web3 native spaces for your community to thrive. Whether it's through cross-community events, shared creative projects, or simply the joy of exploring a new frontier together, the Superchain offers countless opportunities to strengthen the bonds within your community and beyond.

The Based Bridge: Your Path to the Superchain

The Emerald Based Bridge, built on Optimism's native ERC721 bridging smart contracts, makes creating and migrating your NFTs to the Superchain a seamless process:

1. Trustless and Open Source: The Based Bridge is a trustless system, ensuring your NFTs remain fully under your control without hidden fees or restrictions.

2. Flexibility: Users can move their NFTs between Ethereum and the Superchain at any point in time, and in the future easily migrate collections between the Superchain network if needed.

3. Verified for Trust: To maintain a thriving and trusted ecosystem, NFT collections can receive "verified" status by attesting the provenance of their new L2 smart contract address. Teams can expedite this process by connecting with the Based Bridge development team at District Labs. This process helps us prevents scams and phishing attempts, ensuring a safe environment for creators and collectors.

Getting Started

Ready to layer up your NFT collection? Getting started is simple:

1) Deploy: Create a new smart contract address for your collection on the chain of your choice

Before an Ethereum NFT can be bridged to the Superchain, a new L2 NFT must be created, with a direct connection to the original collection address.

You can deploy the new L2 NFT here.

2) Attest: Verify provenance of the new smart contract address as the canonical address for migrated NFTs

The bridge is open and permissionless, so it's important to verify the provenance of the collection using a public social channel, before it's given verified status.

You can verify the collection by creating and sharing an attestation using Ethereum Attestation Station (EAS) or sharing a Twitter/Farcaster post from a verified account stating the mainnet address and the L2 address.

Once the collection has been verified, the NFT collection address will be added to the Emerald Superchain NFT token list and automatically displayed in the application frontend.

3) Bridge: Each NFT holder can bridge their NFT to the new network

Every NFT holder will now be able to see the verified collection in the Based Bridge and will be able to bridge their NFT to the new chain.

And that's it! Your community is now ready to migrate to the Superchain and start experiencing better accessibility, affordability, and endless possibilities.
