选项 1: LaserStream gRPC

最可靠的选项，具有24小时历史重播和多节点故障转移。最适合关键任务后端和索引器。 
npm install helius-laserstream

import { subscribe, CommitmentLevel, LaserstreamConfig, SubscribeRequest } from 'helius-laserstream';

async function main() {
  const subscriptionRequest: SubscribeRequest = {
    transactions: {
      "token-filter": { // user-defined label for this filter
        accountInclude: ['TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA'],
        accountExclude: [],
        accountRequired: [],
        vote: false,
        failed: false
      }
    },
    commitment: CommitmentLevel.CONFIRMED,
    accounts: {},
    slots: {},
    transactionsStatus: {},
    blocks: {},
    blocksMeta: {},
    entry: {},
    accountsDataSlice: [],
  };

  const config: LaserstreamConfig = {
    apiKey: 'YOUR_API_KEY',
    endpoint: 'https://laserstream-mainnet-ewr.helius-rpc.com',
  }

  await subscribe(config, subscriptionRequest, async (data) => {
    console.log(data);
  }, async (error) => {
    console.error(error);
  });
}

main().catch(console.error);

选项 2: LaserStream WebSocket

LaserStream WebSocket 提供 标准 Solana 订阅方法 和 Helius 扩展，比如 transactionSubscribe，在一个统一的端点上。非常适合浏览器/UI 客户端和广泛的生态系统兼容性。 
const WebSocket = require('ws');

const ws = new WebSocket('wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY');

ws.on('open', () => {
  console.log('WebSocket connected');

  // Helius extension: transactionSubscribe with rich filtering
  ws.send(JSON.stringify({
    jsonrpc: "2.0",
    id: 1,
    method: "transactionSubscribe",
    params: [
      {
        accountInclude: ["TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA"],
        vote: false,
        failed: false
      },
      {
        commitment: "confirmed",
        encoding: "jsonParsed",
        transactionDetails: "full"
      }
    ]
  }));

  // Keep connection alive
  setInterval(() => ws.ping(), 30000);
});

ws.on('message', (data) => {
  const message = JSON.parse(data);
  console.log('Transaction:', message);
});
替换 YOUR_API_KEY 使用您在 dashboard.helius.dev 的密钥。

选项 3: Webhooks

适用于无需保持持续连接需要事件通知的服务器端应用程序。 
# Create a webhook
curl -X POST "https://api-mainnet.helius-rpc.com/v0/webhooks" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "webhookURL": "https://your-server.com/webhook",
    "transactionTypes": ["Any"],
    "accountAddresses": ["YOUR_ACCOUNT_ADDRESS"],
    "webhookType": "enhanced"
  }'

// Handle webhook events (Express.js example)
app.post('/webhook', (req, res) => {
  req.body.forEach(event => {
    console.log('Blockchain event:', event);
  });
  res.status(200).send('OK');
});
