Code related to PSBT parsing and serialization.

Documentation

data PartiallySignedTransaction

PSBT data type as specified in BIP-174. This contains an unsigned transaction, inputs and outputs, and unspecified extra data. There is one input per input in the unsigned transaction, and one output per output in the unsigned transaction. The inputs and outputs in the PartiallySignedTransaction line up by index with the inputs and outputs in the unsigned transaction.

merge :: PartiallySignedTransaction -> PartiallySignedTransaction -> Maybe PartiallySignedTransaction

Take two PartiallySignedTransactions and merge them. The unsignedTransaction field in both must be the same.
