Attestation Registry

Signed, expiring eligibility attestations that contracts can check.

What it does

Smart contracts cannot read a passport, but they can check a signature. The Attestation Registry records eligibility attestations signed by an authorised policy service, such as investor class, jurisdiction and expiry, each tied to the version of the rules that produced it. Contracts verify the signature, freshness and policy before a protected action, and an attestation can be revoked the moment a status changes, for example after a sanctions update.

How it works

The Attestation Registry is where identity meets contracts. It records what Verifiable Credentials and the Compliance Engine decide, Data Oracles relay fresh attestations, and any protected action, from investing to voting, can check it.
