Bitcoin Cash P2PKH input -> P2MS output example w/ BITBOX

p2ms-output.js

let mnemonic = '';

// root seed buffer
let rootSeed = BITBOX.Mnemonic.toSeed(mnemonic);

// master HDNode
let masterHDNode = BITBOX.HDNode.fromSeed(rootSeed, 'bitcoincash');

// HDNode of BIP44 account
let account = BITBOX.HDNode.derivePath(masterHDNode, "m/44'/145'/0'");

// derive the first HDNode
let node = BITBOX.HDNode.derivePath(account, "432/123");
// derive the second HDNode
let node2 = BITBOX.HDNode.derivePath(account, "432/124");

// create instance of Transaction Builder class
let transactionBuilder = new BITBOX.TransactionBuilder();

// set original amount, txid and vout
let originalAmount = 18602;
let txid = 'afa0dfb9ba45658da8a247a1ad58c35486077d2139cb0d4d7f0e69864c3e6626';
let vout = 0;

// add input
transactionBuilder.addInput(txid, vout);

// set fee and send amount
let fee = 250;
let sendAmount = originalAmount - fee;

// first HDNode to pubkey
let pubKey1 = BITBOX.HDNode.toPublicKey(node);
// second HDNode to pubkey
let pubKey2 = BITBOX.HDNode.toPublicKey(node2);

// encode pubkeys as 1-of-2 P2MS output
let buf = BITBOX.Script.multisig.output.encode(1, [pubKey1, pubKey2]);

// add output
transactionBuilder.addOutput(buf, sendAmount);

// HDNode to keypair
let keyPair = BITBOX.HDNode.toKeyPair(node);

// empty redeemScript var
let redeemScript;

// sign input
transactionBuilder.sign(0, keyPair, redeemScript, transactionBuilder.hashTypes.SIGHASH_ALL, originalAmount);

// build to hex
let tx = transactionBuilder.build();
let hex = tx.toHex();

// POST tx to BCH network
BITBOX.RawTransactions.sendRawTransaction(hex).then((result) => { console.log(result); }, (err) => { console.log(err); });
