ForkedTxAssembler class

TxAssembler subclass for SIGHASH_FORKID chains (BCH / BSV).

Reuses the parent's signing/attachment flow (TxAssembler.build / TxAssembler.buildAsync) and only swaps in the fork-id sighash algorithm. Like the parent, it now attaches the produced signatures and returns a transaction with complete == true.

Methods

build(SignerCallback signer) → Tx
Builds and signs the transaction synchronously.
inherited
buildAsync(AsyncSignerCallback signer) → Future<Tx>
Async variant of build for hardware wallets / remote signers.
inherited
buildSignedInput(AssemblerInput meta, Uint8List derSig) → TxInput
Builds the concrete signed TxInput for meta from the DER signature bytes returned by the signer (no sighash flag appended yet).
inherited
compareBytes(Uint8List a, Uint8List b) → int
inherited
computeDigest(Tx tx, int index, AssemblerInput meta) → Uint8List
Computes the sighash digest for the input, choosing the algorithm and - for segwit - the BIP-143 scriptCode based on AssemblerInput.type.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
orderedInputs() → List<AssemblerInput>
inherited
orderedOutputs() → List<TxOutput>
inherited
p2wpkhScriptCode(AssemblerInput meta) → Uint8List
BIP-143 scriptCode for P2WPKH / nested P2WPKH: OP_DUP OP_HASH160 <20-byte keyhash> OP_EQUALVERIFY OP_CHECKSIG.
inherited
toString() → String
A string representation of this object.
inherited
unsignedTx(List<AssemblerInput> ins, List<TxOutput> outs) → Tx
