Open-Source. Token Free. Permissionless.**\n\n## Attestations?\nAttestations are digital signatures on structured data, enabling entities like smart contracts, individuals, or businesses to verifiably state facts about anything, i.e. \"I attest this information is valid\". They are foundational for building trust in both online and onchain experiences. We've provided extensive documentation to help you quickly [**learn more about the core concepts**](https://docs.attest.org/docs/category/core-concepts) of EAS and attestations.\n\nWith over **2 million attestations** made, EAS is empowering developers to create reliable and transparent applications. Since you can attest to almost anything, the [**use cases and ideas to build**](https://docs.attest.org/docs/category/ideas-to-build) are virtually limitless.\n\n## Enabling Real World Impact\nReal-world applications on Ethereum often face challenges in bridging the gap between smart contracts and tangible impacts in physical communities. There's a primitive that's been missing. How do we actually decentralize more than just money and assets? \n\nThere have been use cases that have been talked about for a decade like Land Registries, Voting Systems, Supply Chain Provenance, and much more. But how do you actually know who or what data to trust? It needs to be verifiable and signed by an entity that matters. Imagine a world where:\n\n- **Land Registries** are secured by governments or local authorities attesting to land ownership, creating immutable records that reduce fraud and simplify property transfers.\n- **Voting Systems** ensure transparency and security by allowing citizens to attest to their votes.\n- **Supply Chains** are made trustworthy by manufacturers attesting to the origin and authenticity of goods, enhancing traceability.\n- **Healthcare Data** remains secure and private as medical professionals attest to patient information, ensuring only authorized access.\n- **Financial Inclusion** is expanded as organizations attest to micro-loans, savings, and other financial services, helping underbanked communities access essential resources.\n\n### Land registry example on Sepolia:\nThis is an example of a parcel of land being attested to by defining the property type and polygon area.\nhttps://sepolia.easscan.org/attestation/view/0x345567560b051a78d17cdc2669ddc5b859bc6c388b10110f05bb848e7d32655a\n\n\n## Celo Attestation Use Cases\nAttestations provide a straightforward yet powerful way to create digital signatures on data, enabling others to trust and build upon that information. Here’s how attestations can power impactful projects in the Celo ecosystem:\n\n- **Eco Credits:** Validate the origin of carbon credits or other ecological assets, ensuring transparency in environmental projects.\n- **DePIN Infrastructure:** Verify the deployment and maintenance of decentralized infrastructure like solar panels or community wifi, creating trusted records.\n- **RWA Verifications:** Securely attest to the ownership and transfer of physical assets onchain, adding liquidity and security to markets such as real estate.\n\nEAS is also natively integrated into the OP Stack, and with Celo’s upcoming migration to this stack, EAS will be seamlessly available to all Celo developers. In the meantime, EAS is already deployed on [**Celo mainnet**](https://docs.attest.org/docs/quick--start/contracts#celo), ready for immediate use.\n\n\n## Developer tools available\n- [**Open-Source SDK:**](https://github.com/ethereum-attestation-service/eas-sdk) easily integrate EAS into your projects.\n- [**Open-Source Indexer:**](https://github.com/ethereum-attestation-service/eas-indexing-service) efficiently index attestations.\n- [**GraphQL API:**](https://docs.attest.org/docs/developer-tools/api) for querying attestation data\n- [**Celo Attestation Explorer:**](https://celo.easscan.org/) a no-code explorer to make and verify attestations\n- [**EAS Metamask Snap:**](https://docs.attest.org/docs/developer-tools/metamask-snap/) decode onchain attestation data before.\n\n\n## Where we're going next\nOur mantra and focus is simple: **\"Help builders build faster\"**. We are continuously working to improve the developer experience by expanding the protocol's functionality, offering new tools, and creating more comprehensive examples and tutorials. As we grow, your support accelerates the development of EAS and the broader attestation ecosystem, helping to build a more trustful internet.", "logoImgData": {}, "bannerImgData": {}, "projectGithub": "ethereum-attestation-service", "projectTwitter": "eas_eth"}
