Node.js 如何发送比特币BTC使用发送加密使用WIF密钥在 node ，js

这就是最终起作用的代码. 注意，根据版本的不同，比特币代码看起来需要有所不同，根本不是向后兼容的，该代码正在运行2023年10月的最新版本.

// npm install --save send-crypto
// npm install --save bitcoinjs-lib
// npm install --save ecpair
// npm install --save tiny-secp256k1

const bitcoin = require('bitcoinjs-lib');
const ECPairFactory = require('ecpair');
const ecc = require('tiny-secp256k1');
const CryptoAccount = require("send-crypto");

const network = bitcoin.networks.bitcoin;

// Load your private key (WIF)
const ECPair = ECPairFactory.ECPairFactory(ecc);
const privateKeyWIF = 'L3fK...';
const keyPair = ECPair.fromWIF(privateKeyWIF, network);

/* Load account from private key */
//const privateKey = process.env.PRIVATE_KEY || CryptoAccount.newPrivateKey();
const privateKey = keyPair.privateKey;
console.log(privateKey);
const account = new CryptoAccount(privateKey);

async function start() {
    console.log(await account.address("BTC"));

    console.log(await account.getBalance("BTC"));
    console.log(await account.getBalance("BTC", {address:"bc1q..."}));

    const balance = await account.getBalance("BTC");
    await account.send("bc1q...", balance, "BTC", {
            subtractFee: true,
    });

    /*const txHash = await account
            .send("bc1q...", 0.01, "BTC")
            .on("transactionHash", console.log)
            .on("confirmation", console.log);*/


    console.log(await account.getBalance("BTC"));
    console.log(await account.getBalance("BTC", {address:"bc1q..."}));

};
start();
