Haskoin.Transaction.Partial

Code related to PSBT parsing and serialization.

Partially-Signed Transactions

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.

mergeOutput :: Output -> Output -> Output

complete :: PartiallySignedTransaction -> PartiallySignedTransaction

Take partial signatures from all of the Inputs and finalize the signature.

finalTransaction :: PartiallySignedTransaction -> Tx

Take a finalized PartiallySignedTransaction and produce the signed final transaction. You may need to call complete on the PartiallySignedTransaction before producing the final transaction.

emptyPSBT :: Tx -> PartiallySignedTransaction

Take an unsigned transaction and produce an empty PartiallySignedTransaction

emptyInput :: Input

emptyOutput :: Output
