Signing

Real contracts. Real signatures. Real enforceability.

Most influencer agreements are three-paragraph emails with a thumbs-up emoji. PROOF generates a proper PDF with typed-name signatures from both parties, captures the full signing ceremony (IP, timestamp, geo, intent-to-sign clickwrap), and hashes every event onto an append-only audit chain that breaks if tampered with.

The signing ceremony

Everything a court would want to see.

ETA 1999, ESIGN, and eIDAS SES each set out three conditions for an electronic signature: the signer is identified, their intent to sign is explicit, and the record is reliable. PROOF is designed to satisfy all three on every contract.

  • Typed legal name (this is the signature under every modern e-sig law)
  • Explicit intent-to-sign clickwrap — checkbox that locks the typed name to the contract
  • Agreement to terms — separate checkbox confirming the full terms were reviewed
  • Server-side capture: IP address, user-agent, ISO country code, UTC timestamp
  • Consent version — which version of the PROOF electronic-signing notice the signer agreed to

Audit chain

A hash chain that breaks if anything's tampered with.

Every signing event writes to an append-only database table. Each event hashes the previous event's ID + content — so altering any past event would invalidate the chain from that point forward. A database trigger prevents updates and deletes entirely. You can prove the original contract wasn't changed after signature, years later.
