Input

sealed class Input

A PSBT input. A valid PSBT must contain one such input per input of the [Global.tx].

Types

FinalizedInputWithoutUtxo

data class FinalizedInputWithoutUtxo( val scriptWitness: ScriptWitness?, val scriptSig: List<ScriptElt>?, val ripemd160: Set<ByteVector>, val sha256: Set<ByteVector>, val hash160: Set<ByteVector>, val hash256: Set<ByteVector>, val unknown: List<DataEntry>) : Input

A fully signed input without details about the utxo. Input finalizers should keep the utxo to allow transaction extractors to verify the final network serialized transaction, but it's not mandatory, so we may not have it available when parsing psbt inputs.

NonWitnessInput

sealed class NonWitnessInput : Input

An input spending a non-segwit output.

PartiallySignedInputWithoutUtxo

data class PartiallySignedInputWithoutUtxo( val sighashType: Int?, val derivationPaths: Map<PublicKey, KeyPathWithMaster>, val ripemd160: Set<ByteVector>, val sha256: Set<ByteVector>, val hash160: Set<ByteVector>, val hash256: Set<ByteVector>, val unknown: List<DataEntry>) : Input

A partially signed input without details about the utxo. More signatures may need to be added before it can be finalized.

sealed class WitnessInput : Input

An input spending a segwit output.

Properties

derivationPaths

abstract val derivationPaths: Map<PublicKey, KeyPathWithMaster>

Derivation paths used for the signatures.

abstract val hash160: Set<ByteVector>

Hash160 preimages (e.g. for miniscript hash challenges).

abstract val hash256: Set<ByteVector>

Hash256 preimages (e.g. for miniscript hash challenges).

abstract val nonWitnessUtxo: Transaction?

Non-witness utxo, used when spending non-segwit outputs (may also be included when spending segwit outputs).

abstract val partialSigs: Map<PublicKey, ByteVector>

Signatures as would be pushed to the stack from a scriptSig or witness.

abstract val redeemScript: List<ScriptElt>?

Redeem script for this input (when using p2sh).

abstract val ripemd160: Set<ByteVector>

RipeMD160 preimages (e.g. for miniscript hash challenges).

abstract val scriptSig: List<ScriptElt>?

Fully constructed scriptSig with signatures and any other scripts necessary for the input to pass validation.

abstract val scriptWitness: ScriptWitness?

Fully constructed scriptWitness with signatures and any other scripts necessary for the input to pass validation.

abstract val sha256: Set<ByteVector>

Sha256 preimages (e.g. for miniscript hash challenges).

abstract val sighashType: Int?

Sighash type to be used when producing signatures for this output.

abstract val unknown: List<DataEntry>

(optional) Unknown global entries.

abstract val witnessScript: List<ScriptElt>?

Witness script for this input (when using p2wsh).

abstract val witnessUtxo: TxOut?

Witness utxo, used when spending segwit outputs.
