PSBT
A standard format for exchanging unsigned or partially-signed transactions between wallets and signers.
- Also known as
- Partially Signed Bitcoin Transaction
PSBT standardizes how unsigned or partially signed Bitcoin-family transactions are shared between wallets, coordinators, and signing devices. It keeps transaction details, previous-output data, and signatures in a portable format until the transaction is complete.
PSBT is especially useful for air-gapped signing and multisig because each participant can review the same transaction and add only their own signature. Support and exact formats can vary by wallet and chain, so signers should confirm compatibility before relying on a PSBT workflow.
