如何使用JavaScript生成Ton钱包

Question

我在使用 tonweb 库创建 Ton 钱包时遇到问题。 我尝试先生成私钥并从私钥获取公钥，然后从公钥获取地址钱包。 但地址钱包并不依赖于私钥！

const TonWeb = require("tonweb");
const nacl = require("tweetnacl");

(async () => {
  const tonwebInstance = new TonWeb();

  // Generate a random 32-byte private key
  const privateKey = nacl.randomBytes(32);
  const privateKeyHex = Buffer.from(privateKey).toString("hex");

  // Create a key pair from the private key
  const keyPair = nacl.sign.keyPair.fromSeed(privateKey);

  // Extract the public key from the key pair
  const publicKey = keyPair.publicKey;
  const publicKeyHex = Buffer.from(publicKey).toString("hex");

  // Create a wallet using the public key as Uint8Array
  const wallet = tonwebInstance.wallet.create({
    publicKey: publicKey,
  });

  // Get the wallet address
  const walletAddress = (await wallet.getAddress()).toString(true, true, true);

  console.log("Private key (hex):", privateKeyHex);
  console.log("Public key (hex):", publicKeyHex);
  console.log("Wallet address:", walletAddress);
})();

Answer 1

根据

tweetnacl

文档，不建议使用

fromSeed

函数。我已更改您的代码以仅使用推荐的

nacl.sign.keyPair()

函数，并且它可以按预期工作：

const TonWeb = require("tonweb");
const nacl = require("tweetnacl");

(async () => {
  const tonwebInstance = new TonWeb();

  // Create a key pair
  const keyPair = nacl.sign.keyPair();

  // Extract the public key from the key pair
  const publicKey = keyPair.publicKey;
  const publicKeyHex = Buffer.from(publicKey).toString("hex");

  // Extract the private key from the key pair
  const privateKey = keyPair.secretKey;
  const privateKeyHex = Buffer.from(privateKey).toString("hex");

  // Create a wallet using the public key as Uint8Array
  const wallet = tonwebInstance.wallet.create({publicKey});

  // Get the wallet address
  const walletAddress = (await wallet.getAddress()).toString(true, true, true);

  console.log("Wallet address:", walletAddress);
  console.log("Public key (hex):", publicKeyHex);
  console.log("Private key (hex):", privateKeyHex);
})();

输出是 64 字节私钥，而不是之前的 32 字节私钥实现。

Answer 2

@Aaron Meese的答案是正确的👍.

但是我添加这个是因为您特别要求您需要

32-byte

或

privateKey

。默认情况下，

nacl.sign.keyPair()

生成

组合私钥

的64-byte。

组合私钥（64 字节）= 种子（32 字节）+ 公钥（32 字节）

如果您真的想坚持使用

32-byte

中的

privateKey

，您必须从

组合私钥

中slice。

const combinedPrivateKey = keyPair.secretKey; // Seed + Public Key

// Sling first 32 bytes which is Seed that can be used as Private Key
const privateKey = combinedPrivateKey.slice(0, 32);
const privateKeyHex = Buffer.from(privateKey).toString("hex");

你也可以尝试用助记词生成

const createWallet = async () => {
    const tonweb = new TonWeb();
    const words = await generateMnemonic();
    const seed = await mnemonicToSeed(words);
    const keyPair = TonWeb.utils.nacl.sign.keyPair.fromSeed(seed);
    console.log(TonWeb.utils.bytesToHex(keyPair.secretKey));

    const WalletClass = tonweb.wallet.all.v3R2;
    const wallet = new WalletClass(tonweb.provider, {
        publicKey: keyPair.publicKey
    });
    const address = await wallet.getAddress();
    console.log(address.toString(true, true, false)); // print address in format to display in UI
}
