PSBT Analyzer

Understand what you're about to sign — privately.

PSBT stands for Partially Signed Bitcoin Transaction (BIP-174). It's the standard format wallets use when a transaction needs to be reviewed, passed between co-signers, or signed on a hardware device before it's broadcast. If you use a multisig setup, a hardware wallet, or any collaborative signing workflow, you've seen PSBTs — even if you didn't know the name.

Paste your PSBT here for a plain-English breakdown of every input, output, fee, and script. Signing a transaction you don't fully understand is how people lose funds.

Don't paste your PSBT into a big-tech tool that logs your data, fingerprints your wallet, and links your addresses. This runs privately — no account, no tracking, zero data retention.

Zero retention. Your transaction data is processed in memory and never stored. We want your sats, not your data.

Private by design

Your PSBT never leaves a temporary memory buffer. No logs, no training data.
