Legacy platforms require you to trust them. Zero-custody signing eliminates that requirement entirely.
One vendor holds your documents AND your proof. Single point of trust.
Your contracts, signed PDFs, and metadata live on their servers
If they're acquired, breached, or go dark, the audit trail goes with them
One vendor breach can expose every customer's documents
To prove a signature is genuine, you must query their database — no independent path
Storage, orchestration, and proof are three independent parties. No single point of trust.
Documents stay in your S3, Drive, Box, Dropbox, or OneDrive — never ours
Client-side encryption before any byte leaves your device
Solana mainnet anchor + RFC 3161 timestamps — provable without us
Hash-chained log: any change to any row breaks the chain mathematically
No vendor lock-in. No trust assumptions. Just math.
Documents are encrypted in your browser before any byte reaches us. We destroy our working copy after every signer confirms delivery.
Every event — view, consent, OTP, signature, anchor — is a hash-chained row. Any change anywhere breaks the chain mathematically.
Each signature is anchored to Solana mainnet and witnessed by two independent RFC 3161 timestamp authorities. Anyone can verify offline.
Outdated platforms.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 charge $25–65 per user per month. Scale your team from 10 to 50 people? Your costs just jumped $30,000/year.
✗ 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.
Save $20-50K/year

Your branding
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.
