How this service works

Reads Ethereum Attestation Service records for an address and sorts them by what they are actually worth. Each attestation carries its issuer, schema, decoded field values, issue time and expiry. The result separates four states that look identical in a raw list: currently valid, revoked by the issuer, expired, and self-issued — an attestation someone wrote about themselves proves nothing and is counted apart rather than mixed into the total.

Output

A structured list of EAS attestation records for the queried address, each with issuer address, schema identifier, decoded field values, issue time, and expiry. Records are partitioned into four named categories: currently valid, revoked by issuer, expired, and self-issued — making the trust value of each attestation immediately interpretable rather than requiring manual filtering of a raw list.

Example use cases

Onchain identity audit for DeFi access

“Before we let this wallet join our protocol, check its EAS attestations at 0x742d35Cc6634C0532925a3b844Bc454e4438f44e — I need to see which ones are actually valid right now versus revoked or self-signed.”

Credential verification for DAO membership

“Can you fetch the EAS attestation records for 0x1f9090aaE28b8a3dCeaDf281B0F12828e676c326 and tell me if they have any non-self-issued valid attestations? I want to know if their onchain identity holds up.”

Investigating suspicious wallet attestation history

“Look up the Ethereum Attestation Service history for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — I'm specifically interested in how many attestations have been revoked versus how many are still active, and which ones they wrote about themselves.”

When to prefer

Choose this endpoint when you need to assess the onchain identity credibility of an Ethereum address based on EAS attestations, especially when the distinction between valid, revoked, expired, and self-issued attestations matters. It is preferable to raw EAS queries because it pre-categorizes attestation states and decodes schema fields, saving the agent from doing that processing. Useful for DeFi access control, DAO membership checks, reputation scoring, and due diligence on wallets.

Side effects

Invalid or malformed Ethereum address returns a validation error
Address with zero attestations returns empty categorized lists
Network or RPC issues may cause timeouts when fetching onchain data
Schema decoding may fail for non-standard or deprecated EAS schemas
Rate limiting or payment failure prevents the call from executing
