Bitcoin Cash P2PK input -> P2PKH output example w/ BITBOX

p2pk-input.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 HDNode
let node = BITBOX.HDNode.derivePath(account, "432/123");

// cashAddress from HDNode
let cashAddress = BITBOX.HDNode.toCashAddress(node);

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

// set original amount, txid and vout
let originalAmount = 19352;
let txid = '72c2b807e3c9a009ec515bfa86e0fa95a36255f67f7ddda831d4dd1bba313678';
let vout = 0;

// pubkey from HDNode
let pubKey = BITBOX.HDNode.toPublicKey(node);

// encode pubkey as P2PK output
let buf = BITBOX.Script.pubKey.output.encode(pubKey);

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

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

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

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

// empty redeemScript var
let redeemScript;

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

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

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