Key & network

Notary signs both transactions locally — your key never leaves this page. Generate a fresh key or import your own.

Network Blockbook endpoint Key source

Commit

The commit transaction locks funds to the Taproot address that commits to your envelope — without revealing it yet.

Funding UTXOs

Paste UTXOs instead (one txid:vout:value per line)

Fee rate 5 grains/vB

Reveal

Once the commit confirms, the reveal spends it via the script path and publishes your envelope on-chain.

Commit txid Commit vout

The seal

Your notarization is on-chain. This certificate is the audit trail — keep it with the document.

Verify a notarization

Give the verifier the document and the reveal txid. We re-hash the document, fetch the reveal from blockbook, parse its witness exactly like an indexer would, and compare.

Honest limits

Sealing costs real PRL on a live chain. A notarization is two on-chain transactions (commit, then reveal) — it needs a funded address and a reachable Blockbook endpoint. Nothing here broadcasts without your click, and nothing here can seal without funds.
The chain is the witness, not a lawyer. This is proof-of-existence timestamping — it proves a document existed at a time, not who wrote it or whether it is true. Nothing here is legal advice.
Your document never leaves this machine. Only its SHA-256 fingerprint is engraved on-chain; the file or text you drop here is hashed locally.
Confirmations matter. The reveal is only valid once the commit transaction confirms — revealing early burns the fee and seals nothing.
