The receiver validates the transaction, and pays himself. The receiver then adds one or more of his own inputs (known as the ''contributed inputs'') and (optionally) increases the output that pays himself (generally by the sum of the ''contributed inputs''). Doing so creates a ''partial transaction'', which the receiver returns to the sender. It is called such as it requires the sender to re-sign his own inputs.

The receiver MUST validate the ''partial transaction'' was changed correctly and non-maliciously (to allow using potentially untrusted communication channels), re-sign its original inputs and propagate the final transaction over the bitcoin network.
