Class

TransactionInput

A transaction input — a reference to a previous output (TransactionOutPoint) plus the scriptSig and witness data that unlock it.

final class TransactionInput

Overview

Inputs are obtained from a Transaction via input(at:); there is no public create initializer because inputs are only meaningful in the context of a signed transaction.

Wraps the opaque btck_TransactionInput type; deinit calls btck_transaction_input_destroy when the last Swift reference drops.

Instance Properties

var outPoint: TransactionOutPoint
The outpoint this input spends — the (txid, output-index) pair identifying the previous output being consumed. For coinbase inputs, the outpoint’s txid is all zeros and index is 0xFFFFFFFF. Returns an owned copy that outlives this input.
