Seal

Receipts

Every decision through Seal, signed and verifiable

Each row is a signed ATTESTATION-v1 envelope. Outcome is shown as stored on the receipt, not rewritten. Open a row for the signature and the public key it verifies against.

Sample workspace

An operator screen, shown without an account. The records are real signed envelopes from a sample workspace, not production traffic.

A blocked row was signed without the call ever reaching the provider. That is the evidence the policy ran, not a note that it was supposed to.

Now taking pilots.

A free 30-minute evidence review first, then up to five working days on one workflow: one review path, one evidence pack, judged against your reviewer’s own criteria.
