PSBT

Partially Signed Bitcoin Transaction: a format for passing transaction data between wallets and signing devices.

PLAIN-ENGLISH DEFINITION

In more detail

A PSBT lets one tool prepare a payment and another supply the required signatures. That is useful for offline signing, hardware wallets and arrangements with several signers. The format carries the information needed for the workflow; a partly signed file isn't automatically ready to broadcast or safe to approve.

How you might use it

You prepare a PSBT on your computer, sign it on an offline device, then return the signed data to the computer for broadcasting.

PSBT: a transaction-data file with one abstract signature and two empty slots passes between a computer and separate signing device.
