SIGN · 2 of 10

An MSA gets signed with cryptographic human proof.

A Master Services Agreement worth $2M/year is queued for signature. The signing ceremony binds Asha's passkey to the exact contract text. A public proof page anyone can verify is generated - offline, forever, even if Manav no longer exists.

Privacy posture for this scene

The contract carries its own proof - no third-party trust needed.

The signature is bound to sha256(canonical_json(contract_body)) - tampering invalidates it.
The receipt is Ed25519-signed - verifiable offline forever, even if Manav no longer exists.
DocuSign-compatible - drops into existing signature workflows as a higher-assurance option.
