Module bch::transaction

Build and sign transactions

Examples

Sign a transaction:

use bch::messages::{Tx, TxIn};
use bch::transaction::generate_signature;
use bch::transaction::p2pkh::{create_pk_script, create_sig_script};
use bch::transaction::sighash::{sighash, SigHashCache, SIGHASH_FORKID, SIGHASH_NONE};
use bch::util::{hash160, Amount};

// Use real values here
let mut tx = Tx {
    inputs: vec![TxIn {
        ..Default::default()
    }],
    ..Default::default()
};
let private_key = [1; 32];
let public_key = [1; 33];

let pk_script = create_pk_script(&hash160(&public_key));
let mut cache = SigHashCache::new();
let sighash_type = SIGHASH_NONE | SIGHASH_FORKID;
let sighash = sighash(&tx, 0, &pk_script.0, Amount(0), sighash_type, &mut cache).unwrap();
let signature = generate_signature(&private_key, &sighash, sighash_type).unwrap();
tx.inputs[0].sig_script = create_sig_script(&signature, &public_key);
