In a rapidly evolving blockchain landscape characterized by a proliferation of multi-chain ecosystems, maintaining a seamless user experience is paramount. The challenge of non-matching addresses across chains hampers efforts to abstract away the complexities of the multichain paradigm.

Introducing our innovative infrastructure solution, we combine the power of ERC-721 NFTs with the predictability of CREATE3 deployments. Each NFT token ID serves as a unique salt, enabling precise calculation of the deployment address. Ownership of the NFT grants permission for deployment at this specific address.

Across various EVM chains, our smart contract consistently deploys smart contracts to the same address, leveraging CREATE3 for deployment uniformity. To bridge these unified vanity addresses across chains, we harness the decentralized bridging technology offered by Hyperlane, ensuring address consistency and user trust.

Our solution simplifies the deployment of any contract to a harmonized vanity address across chains, effectively abstracting the complexities of the multichain landscape. The result is an enhanced user experience characterized by address uniformity and heightened security, fostering greater user trust.

As we chart the course for the multi-chain future, we extend an invitation to collaborate with us. Our solution pioneers innovative techniques such as NFT-based permissions and bridged CREATE3 deployments, making blockchain more user-friendly and seamless for all.

One of the core components of our infrastructure is the Hyperlane bridge, known for its exceptional permissionless interoperability technology. This technology allows NFT owners to deploy contracts at their vanity addresses across any EVM chain, even those that may not yet be officially supported by our platform. This flexibility is pivotal in ensuring that users can seamlessly extend the benefits of our infrastructure to a wide array of blockchain networks.

In our demonstration, we took the initiative to create a bespoke Remix IDE plugin, streamlining the user experience and providing a user-friendly interface for deploying contracts to vanity addresses. This customization enhances the accessibility and usability of our solution, making it more intuitive for both developers and end-users.

Furthermore, we integrated Vectorized's Solady library into our project, leveraging its capabilities for managing ERC721 tokens and facilitating CREATE3 deployments. This integration not only streamlined our development process but also ensured that we adhered to industry best practices in using efficient smart contract code.
