SOL 钱包开发

账户生成

• 公钥私钥

const solanaWeb3 = require("@solana/web3.js");

// 生成新的密钥对
const keypair = solanaWeb3.Keypair.generate();

console.log("公钥:", keypair.publicKey.toBase58());
console.log("私钥:", keypair.secretKey);

• 助记词

const solanaWeb3 = require('@solana/web3.js');
const bip39 = require('bip39');
const { derivePath } = require('ed25519-hd-key');

// 生成助记词
const mnemonic = bip39.generateMnemonic();
console.log("助记词:", mnemonic);

// 从助记词生成种子
const seed = bip39.mnemonicToSeedSync(mnemonic);

// 使用 Solana 的派生路径 m/44'/501'/0'/0'
const path = "m/44'/501'/0'/0'";
const { key } = derivePath(path, seed.toString('hex'));

// 根据派生的 seed 生成密钥对
const keypair = solanaWeb3.Keypair.fromSeed(key);

console.log("公钥:", keypair.publicKey.toBase58());
console.log("私钥:", keypair.secretKey);

交易信息

• 获取资金

const solanaWeb3 = require("@solana/web3.js");

// 连接到 Solana 的主网
const connection = new solanaWeb3.Connection(
  solanaWeb3.clusterApiUrl("mainnet-beta"),
  "confirmed"
);

// 使用你的公钥创建一个公钥对象
const publicKey = new solanaWeb3.PublicKey(
  "So11111111111111111111111111111111111111112"
);

// 查询账户余额
connection.getBalance(publicKey).then((balance) => {
  console.log("余额:", balance / solanaWeb3.LAMPORTS_PER_SOL, "SOL");
});

• 发送交易

const solanaWeb3 = require("@solana/web3.js");

// 连接到 Solana 的主网
const connection = new solanaWeb3.Connection(
  solanaWeb3.clusterApiUrl("mainnet-beta"),
  "confirmed"
);

// 从密钥创建一个 Keypair（假设你已有私钥）
const secretKey = Uint8Array.from([
  154, 35, 110, 47, 158, 126, 70, 105, 3, 100, 41, 146, 66, 47, 35, 193, 147,

]);
const senderKeypair = solanaWeb3.Keypair.fromSecretKey(secretKey);

// 接收者公钥（将 SOL 发送到的地址）
const recipientPublicKey = new solanaWeb3.PublicKey(
  "Gm14JyqRqPqMr8go2myLbvB4nSX4y3toqmv1kpJCR1A6"
);

// 创建一笔交易
const transaction = new solanaWeb3.Transaction().add(
  solanaWeb3.SystemProgram.transfer({
    fromPubkey: senderKeypair.publicKey,
    toPubkey: recipientPublicKey,
    lamports: 1000000, // 发送的金额，单位是 lamports，1 SOL = 1,000,000,000 lamports
  })
);

// 签署并发送交易
(async () => {
  try {
    const signature = await solanaWeb3.sendAndConfirmTransaction(
      connection,
      transaction,
      [senderKeypair]
    );
    console.log("交易成功，签名:", signature);
  } catch (err) {
    console.error("交易失败:", err);
  }
})();

账户恢复

• 私钥恢复

const solanaWeb3 = require("@solana/web3.js");

// 假设你有一个现有的私钥
const secretKey = Uint8Array.from([
  65, 86, 171, 59, 137, 44, 233, 114, 136, 154, 240, 5, 135, 32, 11, 89, 202,

]);

// 根据私钥还原 Keypair
const keypair = solanaWeb3.Keypair.fromSecretKey(secretKey);

console.log("公钥:", keypair.publicKey.toBase58());
console.log("私钥:", keypair.secretKey);

• 助记词恢复

const bip39 = require("bip39");
const solanaWeb3 = require("@solana/web3.js");
const { derivePath } = require("ed25519-hd-key");

// 假设这是你的助记词
const mnemonic =
  "chunk view deal hen horse visual cook below dish recall awesome upgrade";

// 从助记词生成种子
const seed = bip39.mnemonicToSeedSync(mnemonic);

// 使用 Solana 的派生路径 m/44'/501'/0'/0'
const path = "m/44'/501'/0'/0'";
const { key } = derivePath(path, seed.toString("hex"));

// 通过种子还原密钥对
const keypair = solanaWeb3.Keypair.fromSeed(key);

console.log("还原的公钥:", keypair.publicKey.toBase58());
console.log("还原的私钥:", keypair.secretKey);
