Ethereum Attestation Service (EAS) is an infrastructure public good for making attestations onchain or offchain about anything. Open-source, permissionless, token-free. Built by the community for the community. Live on mainnet, several L2s, & testnets.
Attestations are digital signatures on structured data used to build more trust online & onchain.
How do you decide who and what to trust? Our online and onchain worlds are filled with both genuine and deceptive information. We need a common way we can trust the authenticity of information and the safety of our interactions. Anytime you need to prove or verify something, attestations will play a critical role. Learn more about why we exist.
How It Works
EAS runs on two smart contracts — one for registering a schema and the other for making attestations with schemas. We've also created several dev tools to help builders build faster:
- An attestation explorer to discover and create schemas + attestations
- EAS SDK to easily start building
- GraphQL API for each chain
- Endless Docs for technical & non-technical builders
Who Uses It
We've already seen a few amazing use cases from the community such as:
- Gitcoin Passport stamps & scores can be attested to onchain
- Optimism RetroPGF applications & approvals are attestations (EAS is natively integrated into the OP Stack)
- Coinbase attesting to verified accounts
- Devfolio's quadratic voting for hackathons
- Guild using attestations to gate communities & chat groups
- and many more...
Check out some of the Gitcoin Passport Score attestations coming in.
What We're Excited About
- The Vision
- The diversity in projects people are building with EAS (identity and beyond)
- The impact attestations will make on public goods funding strategies and decentralized governance
- Sybil resistance use cases
- Attesting to the authenticity of content
- Machine to machine attestations
- more ideas to build
Where We're Focused
- We're actively building out improvements to the attestation explorer experience
- Continued builder education, awareness, and adoption
- Building unique integrations such as (zkps generated from attestations)
