EAS is an open standard for making onchain and offchain attestations about anything.

Attestations?

Attestations are digital signatures on structured data, enabling entities like smart contracts, individuals, or businesses to verifiably state facts about anything and allow others to rely on it, i.e. "I attest this information is valid". The docs will help you quickly learn more about the core concepts of EAS and attestations.

Attestations serve as a primitive for building more trustful experiences in online and onchain products. With nearly 8 million attestations made by 439k attesters, EAS is empowering developers to create reliable and transparent applications. Since you can attest to almost anything, the use cases and ideas to build are virtually limitless.

EAS Adoption Highlights

• Coinbase built their Coinbase Verifications product using EAS. This further powers their newly launched Verified Pools product.
• Coinbase Wallet uses EAS to allow builders to more easily attest and manage their token metadata.
• Optimism natively integrated EAS into the OP Stack. Every chain leverages the same EAS predeploy addresses. OP attests to various governance-related needs, like retro funding applications and metadata.
• The Arbitrum Arcade used EAS as a way to attest to profiles and achievements in the gaming campaign via Clique.
• Scroll reinvented how attestations can be used as a replacement for NFT badges in their Scroll Canvas product.

Developer tools and resources

• Open-Source SDK: easily integrate EAS into your projects.
• Open-Source Indexer: efficiently index attestations.
• GraphQL API: for querying attestation data
• EAS Attestation Explorer: a no-code explorer to make and verify attestations
• EAS Metamask Snap: decode onchain attestation data before signing
• Transitive Trust is an open-source algorithm for propagating and computing trust in a relative way. It's an alternative to EigenTrust built for more p2p decentralized networks with high-stakes use cases.
