Free to prove. Pay to publish.

Sealing records, chaining them and signing agreements cost nothing. You only pay to publish a fingerprint to Bitcoin — one credit per anchor. Reading a proof is always free, for anyone, forever.

  • Bilateral agreements, signed with browser-held keys
  • Portable, self-verifying proof bundles

One credit publishes one tip (a table state, or a completed agreement) to Bitcoin via OpenTimestamps. Prices in CAD; taxes added at checkout where applicable. No subscription, no metered API billing.

What you never pay for: reading a proof. Verification is offline, open, and free for anyone you hand a bundle to — forever.
