Built by the community for the community. Live on mainnet, several L2s, & testnets.\n\n> **Attestations are digital signatures on structured data used to build more trust online & onchain.**\n\nHow 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](https://docs.attest.sh/docs/purpose/eas-purpose).\n\n## How It Works\nEAS runs on [two smart contracts](https://github.com/ethereum-attestation-service) — 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:\n\n- An [attestation explorer](https://docs.attest.sh/docs/easscan/overview) to discover and create schemas + attestations\n- [EAS SDK](https://docs.attest.sh/docs/developer-tools/eas-sdk) to easily start building\n- [GraphQL API](https://docs.attest.sh/docs/developer-tools/api) for each chain\n- [Endless Docs](https://docs.attest.sh/docs/welcome) for technical & non-technical builders\n\n## Who Uses It\nWe've already seen a few amazing use cases from the community such as:\n\n- [Gitcoin Passport](https://optimism.easscan.org/schema/view/0x6ab5d34260fca0cfcf0e76e96d439cace6aa7c3c019d7c4580ed52c6845e9c89) stamps & scores can be attested to onchain\n- [Optimism RetroPGF](https://optimism.easscan.org/schema/view/0xebbf697d5d3ca4b53579917ffc3597fb8d1a85b8c6ca10ec10039709903b9277) applications & approvals are attestations (EAS is natively integrated into the OP Stack)\n- [Coinbase](https://base.easscan.org/address/0x357458739F90461b99789350868CD7CF330Dd7EE) attesting to verified accounts\n- [Devfolio's](https://arbitrum.easscan.org/schema/view/0x951fa7e07d6e852eb4535331db373786f5ab7249bb31d94cc4bd05250ebb6500) quadratic voting for hackathons\n- [Guild](https://x.com/guildxyz/status/1699085302281671124?s=20) using attestations to gate communities & chat groups\n- and many more...\n\nCheck out some of the [Gitcoin Passport Score](https://optimism.easscan.org/schema/view/0x6ab5d34260fca0cfcf0e76e96d439cace6aa7c3c019d7c4580ed52c6845e9c89) attestations coming in.\n![Gitcoin Passport Score Attestations](https://docs.attest.sh/assets/images/explorer-landing-a0b436a39afc04734034e3c8ee396ce3.png)\n\n## What We're Excited About\n- [The Vision](https://docs.attest.sh/docs/purpose/the-vision)\n- The diversity in projects people are building with EAS (identity and beyond)\n- The impact attestations will make on public goods funding strategies and decentralized governance\n- Sybil resistance use cases \n- Attesting to the authenticity of content\n- Machine to machine attestations\n- more [ideas to build](https://docs.attest.sh/docs/category/ideas-to-build)\n\n## Where We're Focused\n- We're actively building out improvements to the attestation explorer experience\n- Continued builder education, awareness, and adoption\n- Building unique integrations such as (zkps generated from attestations)\n\n## Get In Touch With Us & Check Out Some Community Content\n\nCommunity Content:\n- [Ethereum Attestation Service - Unlocking Decentralized Identity - Bankless Podcast](https://www.youtube.com/watch?v=RsIBqExwsT8)\n- [Ethereum Attestation Service (EAS) - Explainer Video - Vaibhav Saini](https://www.youtube.com/watch?v=8bbkI5MIWm8&)\n- [ELI5 Ethereum Attestation Service (EAS) - Why You Should Care - Ryan Yi](https://mirror.xyz/ryanyyi.eth/Q0NMTOpazMUeXuifPmxebxnyVJuUExEH7K8Qbu7HLy0)\n- [Onchain Attestation Stats - Dune Dashboard - Ryan Yi](https://dune.com/ryanyyi/eas)\n\nEAS Channels:\n- [EAS Twitter (@eas_eth)](https://twitter.com/eas_eth)\n- [Mirror Articles](https://mirror.xyz/0xeee68aECeB4A9e9f328a46c39F50d83fA0239cDF)\n- [Builder Telegram](https://t.me/+EcynOr0iFu03MTYx)\n- [EAS GitHub](https://github.com/ethereum-attestation-service)", "logoImgData": {}, "bannerImgData": {}, "projectGithub": "ethereum-attestation-service", "projectTwitter": "eas_eth"}
