I’m using the bitcoin rust crate to build my own CLI wallet.
In my function where I’m constructing the TxIn‘s for my Transaction, is the actual script_sig required at the below step? Or does it populate when I go and sign the transaction in a later step?
let txins: Vec = selected_utxos
.iter()
.map(|utxo| TxIn {
previous_output: bitcoin::OutPoint {
txid: bitcoin::Txid::from_str(&utxo.txid).expect("Invalid txid format"),
vout: utxo.vout,
},
script_sig: ScriptBuf::new(),
sequence: Sequence::MAX,
witness: Witness::new(),
})
.collect();
Is it ok to put ScriptBuf::new() as a placeholder?
