Most e-signature platforms ask you to trust their servers. AdaptDoc gives you independently verifiable proof.
Every completed document is hashed using SHA-256. If a single character is altered after signing, the hash won't match. Proof of tampering is mathematical, not just a claim.
Every signed document gets a unique verification code and QR stamp on every page. Anyone — a judge, a bank, a landlord — can verify authenticity at doc.adaptensor.com/verify without creating an account.
Documents are stored in private Vercel Blob storage. Every access — preview, download, email — requires a cryptographic Bearer token. No document is ever publicly accessible by URL alone.
Every action is logged: IP address, timestamp, browser/device, geographic location, and signing method. The audit trail is immutable and exported as a PDF with every completed document.
The Signing Certificate — with verification code, integrity hash, signer table, and QR code — is appended as the final page of every completed document. No separate file to lose.
AdaptDoc signatures meet all four ESIGN Act requirements, full UETA adoption, and eIDAS advanced electronic signature standards. Legally binding in all 50 US states and internationally.
No hidden fees. No per-envelope charges. Cancel anytime.
