Attestation

Attestation

This struct represents an on-chain attestation record. This record is not deleted after revocation.

schemaId: The Schema that this Attestation is based on. It must exist.

linkedAttestationId: Useful if the current Attestation references a previous Attestation. It can either be 0 or an existing attestation ID.

attestTimestamp: When the attestation was made. This is automatically populated by _attest(...).

revokeTimestamp: When the attestation was revoked. This is automatically populated by _revoke(...).

attester: The attester. At this time, the attester must be the caller of attest().

validUntil: The expiration timestamp of the Attestation. Must respect Schema.maxValidFor. 0 indicates no expiration date.

dataLocation: Where Attestation.data is stored. See DataLocation.DataLocation.

revoked: If the Attestation has been revoked. It is possible to make a revoked Attestation.

recipients: The intended ABI-encoded recipients of this Attestation. This is of type bytes to support non-EVM repicients.

data: The raw data of the Attestation based on Schema.schema. There is no enforcement here, however. Recommended to use abi.encode.

OffchainAttestation

This struct represents an off-chain attestation record. This record is not deleted after revocation.

attester: The attester. At this time, the attester must be the caller of attestOffchain().

timestamp: The block.timestamp of the function call.

  address attester;
  uint64 timestamp;
