An MSA gets signed with cryptographic human proof.
A Master Services Agreement worth $2M/year is queued for signature. The signature ceremony binds Asha's passkey to the exact contract text. A public proof page anyone can verify is generated and linked into the document.
Privacy posture for this scene
The contract carries its own proof, no third-party trust needed.
- The signature is bound to the hash of the contract's canonical content; tampering invalidates it.
- The proof page is verifiable by counterparty counsel without calling Manav.
- DocuSign-compatible, drops into existing signature workflows as a higher-assurance option.
