Document Signing Privacy
Multi-party contracts share the entire document — Polymonial gives each signatory only the slice they need to see.
The problem to solve
Multi-party contracts (MSAs, SaaS agreements, lease deals, employment contracts) get signed via e-signature workflows. Every signatory receives the complete document — including pricing, payment terms, indemnity caps, party identities. The notary, the witness, the KYC verifier, the lawyer all see the lot. Confidentiality is policy + NDA, not technical.
The solution it enables
Schema-wrap the contract. Each clause / field has its own access list. The signatory signs over their own slice's seal. Witness verifies signature presence without seeing payment terms. KYC verifier confirms identity without seeing pricing. The contract is one document, but each role sees only their slice.
What it looks like
A commercial-property lease involves landlord, tenant, lawyer, surveyor, two witnesses, and the lender. The contract carries the rent, deposit, indemnity cap, surveyed valuation, and party identities. Today: every party signs the full document; every party sees the lot. After Polymonial: schema defines who reads what. Witnesses verify signature presence on the relevant signature block; lender unseals the financial terms; surveyor unseals only the valuation; tenant + landlord unseal everything (their contract). Same e-signature envelope; selective slices.
“Sign the contract. The witness witnesses the signature. They don't read the deal.”
