Electronic signatures backed by independently verifiable evidence to give you lasting confidence in every agreement.
SignaTrust stores your documents while they're being signed and keeps an evidence record for every envelope. Connect your own cloud storage and completed, signed PDFs are exported there automatically. Each completed document's fingerprint is anchored to the Solana blockchain, and the audit trail is timestamped by an independent authority under RFC 3161. Anyone can check a signed document's record on our public verification page without a SignaTrust account. When you use AI contract review, the document is sent to our AI provider for analysis.

A Solana anchor and RFC 3161 timestamps, checkable without a SignaTrust account.
AI contract review and field detection send the document to our AI provider.
No vendor lock-in. No trust assumptions. Just math.
Every event — view, consent, OTP, signature, anchor — is a hash-chained row, and stamped rows carry an RFC 3161 token from an independent authority. Any change anywhere breaks the chain mathematically.
Each signature is anchored to Solana mainnet, and stamped audit events carry an RFC 3161 token from an independent authority. Two independent trust roots — both travel in the bundle, verifiable without a SignaTrust account.
Outdated platforms. Priced like it's cutting edge.
Your audit trails live in their database. If they go bankrupt or change terms, you lose verification history. You're trapped.
✗ No independent verification
Legacy e-signature platforms price by the user, so every hire raises the bill — whether or not that person sends anything.
✗ Costs scale with headcount
Legacy tools just route documents. No AI analysis, no risk detection, no help understanding what you're signing.
✗ Sign blindly, regret later
Legacy per-seat platforms explode in cost as you hire. SignaTrust stays flat.
Priced per team
Independently verifiable evidence for every envelope. AI flags risky clauses.

Legacy e-signature providers built their technology 20+ years ago and are coasting on market share. They charge per-user because they can, lock you into their verification databases because you have no choice, and offer zero intelligence because they never innovated.
SignaTrust is different. We're building the e-signature platform that should exist in 2026: blockchain-verified, AI-powered, API-first, and priced for modern businesses.
