Revoke an Attestation

Revocation is done through the portal that originally issued the attestation.

Portal interface​

AbstractPortalV2 exposes:

function revoke(bytes32 attestationId) public onlyPortalOwner;

function bulkRevoke(bytes32[] memory attestationIds) public onlyPortalOwner;

By default, only the portal owner can revoke.

Registry checks​

AttestationRegistry.revoke(...) checks:

  • the attestation exists;
  • it is not already revoked;
  • the calling portal is the original attesting portal;
  • the portal is marked revocable in PortalRegistry.

SDK​

await veraxSdk.portal.revoke("0xPortalAddress", "0xAttestationId", {
  waitForConfirmation: true,
});

await veraxSdk.portal.bulkRevoke("0xPortalAddress", ["0xAttestationId1", "0xAttestationId2"], {
  waitForConfirmation: true,
});

Custom portal logic​

You can add extra revocation logic in:

  • _onRevoke(attestationId)
  • _onBulkRevoke(attestationIds)

But the default owner-only protection is already present in AbstractPortalV2.
