使用 Helius SDK 进行编程化 Solana 质押

零佣金验证器：使用 Helius 验证器进行质押，享受 0% 佣金率，保留 100% 的质押奖励。

快速概览

Helius SDK 提供简单的方法以编程方式处理完整的 SOL 质押生命周期。非常适合构建质押界面、DeFi 协议或自动化质押策略。

创建与委托

在一次交易中设置新的质押账户并委托给验证器

监控与管理

跟踪奖励、检查状态并管理现有质押账户

提现与赎回

在冷却期后停用质押并提取 SOL

安装与设置

npm install helius-sdk @solana/web3.js bs58

import { Helius } from 'helius-sdk';
import { Keypair, Transaction } from '@solana/web3.js';
import bs58 from 'bs58';

// Initialize Helius client
const helius = new Helius('YOUR_API_KEY');

// Your wallet keypair (load from your secure storage)
const payer = Keypair.fromSecretKey(/* your secret key */);

质押基础

Solana 质押如何运作

质押账户：一种特殊账户，用于锁定 SOL 并将其委托给验证器。每个质押账户仅指向一个验证器。奖励：验证器通过保障网络安全获得奖励。这些奖励分配给所有委托给该验证器的质押账户。生命周期：创建 → 委托 → 获得奖励 → 停用 → 提现

为何选择 Helius 验证器

0% 佣金：保留 100% 的质押奖励
高性能：可靠的区块生产和最小的停机时间
易于集成：针对 Helius SDK 优化，内置辅助工具

时间与周期

激活：质押在下一个周期开始时生效（约 2 天）
停用：在当前周期结束时生效
冷却：停用的质押可在周期结束后立即提取

入门指南

快速开始
完整示例

仅需三行代码即可质押 SOL：

// 1. Create the staking transaction
const { serializedTx, stakeAccountPubkey } = 
  await helius.rpc.createStakeTransaction(payer.publicKey, 1.5);

// 2. Sign and send
const tx = Transaction.from(bs58.decode(serializedTx));
tx.partialSign(payer);
const signature = await helius.connection.sendRawTransaction(tx.serialize());

console.log(`Staked! Transaction: ${signature}`);
console.log(`Stake Account: ${stakeAccountPubkey}`);

SDK 会自动处理租金计算和质押账户创建。1.5 参数是您想要质押的 SOL 数量。

包含错误处理的完整质押实现：

async function stakeSOL(amountInSol: number) {
  try {
    // Create staking transaction
    const { serializedTx, stakeAccountPubkey } = 
      await helius.rpc.createStakeTransaction(payer.publicKey, amountInSol);
    
    // Deserialize and sign transaction
    const transaction = Transaction.from(bs58.decode(serializedTx));
    transaction.partialSign(payer);
    
    // Send transaction
    const signature = await helius.connection.sendRawTransaction(
      transaction.serialize(),
      { 
        skipPreflight: false,
        preflightCommitment: 'confirmed'
      }
    );
    
    // Wait for confirmation
    await helius.connection.confirmTransaction(signature, 'confirmed');
    
    return {
      signature,
      stakeAccount: stakeAccountPubkey,
      amount: amountInSol
    };
    
  } catch (error) {
    console.error('Staking failed:', error);
    throw error;
  }
}

// Usage
const result = await stakeSOL(2.5);
console.log(`Successfully staked ${result.amount} SOL`);

SDK 方法参考

createStakeTransaction(owner, amount)

创建一个可以签名和发送的完整质押交易。参数：

owner (PublicKey): 将拥有质押账户的钱包
amount (number): 要质押的 SOL 数量

返回：

{
  serializedTx: string,        // Base58 encoded transaction
  stakeAccountPubkey: string   // New stake account address
}

示例：

const result = await helius.rpc.createStakeTransaction(
  payer.publicKey, 
  1.5  // 1.5 SOL
);

getStakeInstructions(owner, amount)

返回质押指令（对于自定义交易构建很有用）。返回：

{
  instructions: TransactionInstruction[],
  stakeAccount: Keypair
}

示例：

const { instructions } = await helius.rpc.getStakeInstructions(
  payer.publicKey, 
  1.5
);

// Use with Smart Transactions
const signature = await helius.rpc.sendSmartTransaction(
  instructions, 
  [payer]
);

getHeliusStakeAccounts(wallet)

检索委托给 Helius 验证器的钱包的所有质押账户。示例：

const accounts = await helius.rpc.getHeliusStakeAccounts(
  payer.publicKey.toBase58()
);

accounts.forEach(account => {
  const delegation = account.account.data.parsed.info.stake.delegation;
  console.log(`Account: ${account.pubkey}`);
  console.log(`Stake: ${delegation.stake / LAMPORTS_PER_SOL} SOL`);
});

createUnstakeTransaction(owner, stakeAccount)

创建一个交易以停用（开始取消质押）质押账户。示例：

const tx = await helius.rpc.createUnstakeTransaction(
  payer.publicKey,
  stakeAccountPubkey
);

const transaction = Transaction.from(bs58.decode(tx));
transaction.partialSign(payer);
await helius.connection.sendRawTransaction(transaction.serialize());

getWithdrawableAmount(stakeAccount, includeRent?)

检查可以从已停用的质押账户中提取多少 SOL。参数：

includeRent (boolean): 是否包括免租金额

示例：

const available = await helius.rpc.getWithdrawableAmount(stakeAccountPubkey);
const total = await helius.rpc.getWithdrawableAmount(stakeAccountPubkey, true);

console.log(`Available now: ${available / LAMPORTS_PER_SOL} SOL`);
console.log(`Total balance: ${total / LAMPORTS_PER_SOL} SOL`);

createWithdrawTransaction(owner, stakeAccount, destination, amount)

创建一个交易以从已停用的质押账户中提取 SOL。示例：

const tx = await helius.rpc.createWithdrawTransaction(
  payer.publicKey,
  stakeAccountPubkey,
  destinationPubkey,
  withdrawAmount  // in lamports
);

完整质押工作流程

创建和委托

// Stake 2 SOL to Helius validator
const { serializedTx, stakeAccountPubkey } = 
  await helius.rpc.createStakeTransaction(payer.publicKey, 2.0);

const tx = Transaction.from(bs58.decode(serializedTx));
tx.partialSign(payer);

const signature = await helius.connection.sendRawTransaction(tx.serialize());
console.log(`Stake created: ${stakeAccountPubkey}`);

监控您的质押

// Get all your Helius stake accounts
const accounts = await helius.rpc.getHeliusStakeAccounts(
  payer.publicKey.toBase58()
);

console.log(`You have ${accounts.length} active stake accounts`);

accounts.forEach((account, index) => {
  const info = account.account.data.parsed.info;
  const delegation = info.stake.delegation;
  
  console.log(`Stake ${index + 1}:`);
  console.log(`  Amount: ${delegation.stake / LAMPORTS_PER_SOL} SOL`);
  console.log(`  Activated: Epoch ${delegation.activationEpoch}`);
  console.log(`  Status: ${info.meta.lockup.unixTimestamp === 0 ? 'Active' : 'Locked'}`);
});

停用（开始解除质押）

// Begin the unstaking process
const unstakeTx = await helius.rpc.createUnstakeTransaction(
  payer.publicKey,
  stakeAccountPubkey
);

const tx = Transaction.from(bs58.decode(unstakeTx));
tx.partialSign(payer);

await helius.connection.sendRawTransaction(tx.serialize());
console.log('Deactivation started. Will be withdrawable next epoch.');

提取 SOL

// Check withdrawable amount
const withdrawable = await helius.rpc.getWithdrawableAmount(
  stakeAccountPubkey, 
  true  // include rent
);

if (withdrawable > 0) {
  // Create withdrawal instruction
  const withdrawInstruction = helius.rpc.getWithdrawInstruction(
    payer.publicKey,
    stakeAccountPubkey,
    payer.publicKey,  // withdraw to same wallet
    withdrawable
  );
  
  // Send using Smart Transactions for better reliability
  const signature = await helius.rpc.sendSmartTransaction(
    [withdrawInstruction], 
    [payer]
  );
  
  console.log(`Withdrawn ${withdrawable / LAMPORTS_PER_SOL} SOL`);
}

智能交易

对于使用钱包适配器的浏览器应用程序：

// Get instructions instead of full transaction
const { instructions, stakeAccount } = await helius.rpc.getStakeInstructions(
  wallet.publicKey,
  stakeAmount
);

// Let the wallet handle transaction building and signing
const transaction = new Transaction().add(...instructions);

// Sign with wallet adapter
const signature = await wallet.sendTransaction(transaction, connection);

console.log(`Stake account: ${stakeAccount.publicKey.toBase58()}`);

高效地为多个钱包进行质押：

async function batchStake(wallets: Keypair[], amount: number) {
  const promises = wallets.map(async (wallet) => {
    try {
      const { serializedTx, stakeAccountPubkey } = 
        await helius.rpc.createStakeTransaction(wallet.publicKey, amount);
      
      const tx = Transaction.from(bs58.decode(serializedTx));
      tx.partialSign(wallet);
      
      return helius.connection.sendRawTransaction(tx.serialize());
    } catch (error) {
      console.error(`Failed to stake for ${wallet.publicKey.toBase58()}:`, error);
      return null;
    }
  });
  
  const results = await Promise.allSettled(promises);
  const successful = results.filter(r => r.status === 'fulfilled').length;
  
  console.log(`Successfully staked for ${successful}/${wallets.length} wallets`);
}

使用智能交易以提高可靠性和优化：

// Get individual instructions
const { instructions } = await helius.rpc.getStakeInstructions(
  payer.publicKey,
  2.5
);

// Send with Smart Transaction features:
// - Automatic priority fee optimization
// - Retry logic with backoff
// - Better error handling
const signature = await helius.rpc.sendSmartTransaction(
  instructions,
  [payer],
  {
    skipPreflight: false,
    maxRetries: 3
  }
);

console.log(`Smart transaction sent: ${signature}`);

重要提示

Epoch 时间：Solana 的 epoch 大约持续 2 天。质押在下一个 epoch 开始时激活，停用在当前 epoch 结束时生效。

租金考虑：质押账户需要租金豁免储备（约 0.00228 SOL）。提取全部余额将关闭账户。

硬件钱包：用户将看到两个签名提示 - 一个用于质押账户（预签名），另一个用于费用支付者。请相应设计您的用户体验。

快速参考

需要快速提醒吗？以下是基本方法：

// Stake SOL
await helius.rpc.createStakeTransaction(owner, amountInSol);

// Check your stakes  
await helius.rpc.getHeliusStakeAccounts(ownerAddress);

// Start unstaking
await helius.rpc.createUnstakeTransaction(owner, stakeAccount);

// Check withdrawable amount
await helius.rpc.getWithdrawableAmount(stakeAccount, includeRent);

// Withdraw SOL
helius.rpc.getWithdrawInstruction(owner, stakeAccount, destination, amount);
