This guide lists some of the applications that use attestations.

Ethereum Attestation Service

These are some of the applications that use the attestations:

• EAS Scan (opens in a new tab): This no-code interface lets you build schemas, query, and submit attestations.
• Citizen Attestations (opens in a new tab): An attestation explorer for Optimism focusing on attestations that are relevant for the OP Citizens eligibility process.
• Attest Fest (opens in a new tab): Create multiple EAS attestations using the power of CSV and Safe multisig wallets. It's an attest fest, yay!
• Optimist Profile (opens in a new tab): The Optimist Profile allows contributors to share the contributions and impact they've made to the Optimism Collective.
• Ethereum Ecosystem onchain reviews (opens in a new tab): The goal of this Attestation-Based Dapp Rating web app is to allow anyone to review dApps and tools 100% onchain.
