Methods
-
addScripts(
{required UtxoWithAddress utxo, required TxInput input, required List< String> signatures}) → void -
buildInputs(
) → List< TxInput> -
buildInputScriptPubKeys(
UtxoWithAddress utxo) → Script - It is used to make the appropriate scriptSig
-
buildMiltisigUnlockingScript(
List< String> signedDigest, UtxoWithAddress utx) → List<String> - buildP2wshOrP2shScriptSig constructs and returns a script signature (represented as a List of strings) for a Pay-to-Witness-Script-Hash (P2WSH) or Pay-to-Script-Hash (P2SH) input. The function combines the signed transaction digest with the script details of the multi-signature address owned by the UTXO owner. Parameters:
-
buildOutputs(
) → List< TxOutput> -
buildOutputScriptPubKey(
BitcoinOutput addr) → Script -
buildTransaction(
BitcoinSignerCallBack sign) → BtcTransaction -
buildUnlockingScript(
String signedDigest, UtxoWithAddress utx) → List< String> -
generateTransactionDigest(
Script scriptPubKeys, int input, UtxoWithAddress utox, BtcTransaction transaction) → List< int> - generateTransactionDigest generates and returns a transaction digest for a given input in the context of a Bitcoin transaction. The digest is used for signing the transaction input. The function takes into account whether the associated UTXO is Segregated Witness (SegWit) or Pay-to-Taproot (P2TR), and it computes the appropriate digest based on these conditions. Parameters:
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
opReturn(
String message) → Script -
sumOutputAmounts(
) → BigInt - Total amount to spend excluding fees
-
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.

Static Methods
-
estimateTransactionSize(
{required List< UtxoWithAddress> utxos, required List<BitcoinAddress> outputs, required BitcoinNetwork network, String? memo, bool enableRBF = false}) → int - This method is used to create a dummy transaction, allowing us to obtain the size of the original transaction before conducting the actual transaction. This helps us estimate the transaction cost
