Use this tag for questions related to BIP 174 - Partially Signed Bitcoin Transactions (PSBT).

BIP 174 proposes a format for partially signed bitcoin transactions. It is designed to be standardized and extensible, allowing different wallet implementations to pass messages around to collaboratively build transactions in a trustless manner. It also works well in situations of offline signing.
