Audit Trail
Who signed, when, and what was attached. A complete history of every document interaction, accessible anytime.
Cryptographic Verification
Every signature carries a cryptographic stamp. Verifiable authenticity without exposing personal data onchain.
Premium Add-Ons
Our team builds and maintains your templates. Complex agreements, custom fields, specific workflows. We handle it.
Don't Just Sign, Actually Execute
Most signing tools collect a signature and stop. Then you chase wire instructions, log into a bank portal, and manually reconcile.
With Mezzanine, signing & paying are completed in same place. The deal is done when it's actually closed & executed. No follow-ups or manual reconciliation.
