EAS.getAttestation
getAttestation(bytes32 uid) external view returns (Attestation memory) Returns the full Attestation struct for a given UID, or an Attestation with uid == 0x00.. if the UID is unknown. This is the canonical read on the EAS contract preinstall — every other surface (@ethereum-attestation-service/eas-sdk, the Indexer, PCL's EAS_POLICY evaluator) ultimately calls this. dApp code should validate revocationTime == 0 and (expirationTime == 0 || expirationTime > now) before treating an attestation as valid.
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
uid | bytes32 | ✓ | The 32-byte unique identifier of the attestation. |
Returns
Attestation Struct fields: uid (bytes32), schema (bytes32), time (uint64, attestation timestamp), expirationTime (uint64, 0 = never), revocationTime (uint64, 0 = not revoked), refUID (bytes32, optional reference to another attestation), recipient (address), attester (address), revocable (bool), data (bytes, schema-encoded payload).
