The custodian
A proof of reserves is a signed statement: we control these addresses, and here is what we owe. Anyone can verify the signatures and re-add the on-chain balances. No account, no server — the statement is a tamper-evident bundle you can publish anywhere.
The addresses
Paste every prl1p… address the custodian claims to control — one per line
(up to 250). Each must be a v1 Taproot address on the selected network. Duplicates are merged silently;
anything else is rejected loudly.
The proof
For each address, enter the private key that controls it — WIF, 64-hex, or a 12/24-word mnemonic (BIP-86 account 0). The page derives the keypath address and refuses any key that does not reproduce the listed address exactly, then signs the canonical challenge with the tweaked key. Keys are wiped from memory the moment signing finishes.
Air-gap (sign on a cold device)
Export the unsigned challenge bundle, sign each challenge offline (this same page works offline once loaded), then import the signatures below.
The statement
The tamper-evident proof bundle. The 64-bit fingerprint commits to the custodian name, liabilities, date, nonce, and every signature — editing any field breaks the fingerprint. Publish this JSON anywhere: a website, a tweet, an IPFS pin.
- Bundle fingerprint
- Signed addresses
- Declared liabilities
The verdict
Paste any pearl-solvency:v1 bundle — yours or someone else's. The page
re-validates the fingerprint, checks every challenge signature, then reads each address's
confirmed UTXOs from Blockbook (GET-only), byte-comparing every funding output script against the address.
Foreign-script UTXOs are excluded, never trusted.
