Attest by DataHubz is document signing and verifiable records. The Attest connector brings your Attest records into your assistant. What you can do: - See your agreements: the ones you sent and the ones waiting for your signature, with their status, signers, whose turn it is and the audit trail up to completion. - Remind signers of an agreement you sent: the signing link goes again to those whose turn it is, at most once a day each. - Prepare a new agreement: give the title, signers, order, a note and an expiry date, and get a link to Attest's New agreement form, filled in. You attach the PDF and send it in Attest, where your browser encrypts it. - Verify a signed document: give the code on its signature stamp (ATT-XXXX-XXXX), an agreement, receipt or proof ID, or the file's SHA-256 fingerprint. Attest reports who signed, whether every passkey signature checks out, and the record's anchor on the Base blockchain. Anyone can run this check, without an account. - Prove you signed an agreement without revealing it: a Share proof is a zero-knowledge proof that shows your email address (and a co-signer's, if you name one) and the day the agreement was completed, never the document, its terms or its title. Each proof is submitted to zkVerify for independent verification. - Record a receipt: anchor a SHA-256 fingerprint on Base as proof that the content existed, unchanged, at that time. What it can't do, by design: - It can't read your documents. They are end-to-end encrypted in the sender's browser and stored only as ciphertext Attest can't read, so no tool returns a document. - It can't sign. Each signer signs in Attest with their own passkey (Face ID, Touch ID, Windows Hello or the device PIN). - It doesn't send documents. You send them from Attest. You sign in to Attest when you connect and choose what the assistant may do: check records, read your records, or act on them. You can disconnect it at any time from Attest's Security page.
