It’s open-source, permissionless, and token-free.\n\nAttestations are simply digital signatures on structured data used to build more trust online and onchain. EAS is an open standard where any entity can make attestations about anything. You simply register a schema (or use an existing one) about any topic and make attestations referencing that schema. Additional utilities extend the functionality while making the protocol highly composable and easy to build upon. \n\nThis primitive and ledger of attestations will help us decentralize more than just money and assets. We'll be able to coordinate and build reputation systems, voting systems, governance systems, decentralized social media, provenance of goods, knowledge and social graphs, content authenticity platforms, and much much more.\n\n## Available Mainnets:\nEthereum, Optimism, Base, Arbitrum, Polygon, Linea, Celo, Scroll\n\n## Attestation Examples:\n- Optimism natively integrated EAS into the OP Stack linked by two predeploy addresses. It was used for retropgf3 and other governance use cases.\n- Coinbase uses EAS for their Coinbase Verifications product\n- Gitcoin Passport uses EAS to attest to passport scores and stamps onchain", "logoImgData": {}, "bannerImgData": {}, "projectGithub": "ethereum-attestation-service", "projectTwitter": "eas_eth"}
