通过 WebSocket 订阅 Solana 兑换交易

订阅 transaction:{tokenAddress} 获取代币兑换交易。可按池或钱包缩小范围；流动性增减使用单独的房间。

同时追踪流动性。 订阅 liquidity:{mint} 接收流动性增减，或在代币交易 API 中使用 events=all 合并兑换交易与流动性活动。查看流动性指南。在交易或流动性房间后添加 :enriched 可获取钱包身份。

URL: wss://datastream.solanatracker.io/{apiKey}
适用于 Premium、Business 和 Enterprise 方案。

订阅某代币的交易

加入 transaction:{tokenAddress} room 以接收代币的所有兑换:

const token = "6p6xgHyF7AeE6TZkSmFsko444wqoP15icUSqi2jfGiPN";
const ws = new WebSocket("wss://datastream.solanatracker.io/YOUR_API_KEY");

ws.onopen = () => {
  ws.send(JSON.stringify({ type: "join", room: `transaction:${token}` }));
};

ws.onmessage = (event) => {
  const msg = JSON.parse(event.data);
  if (msg.type !== "message") return;

  // msg.data is an array of transactions
  msg.data.forEach(tx => {
    const side  = tx.type === "buy" ? "BUY " : "SELL";
    const usd   = tx.volume.toFixed(2);
    const price = tx.priceUsd.toFixed(6);
    console.log(`${side} $${usd} @ $${price} — ${tx.wallet.slice(0, 8)}... via ${tx.program}`);
  });
};

交易 payload:

{
  "tx": "5V4apVkgHf49J5acYPiuh5rB89EGsF8ocSysgnD9vFfZsTtDamhN3MFDKJSq7Dn7Z6Y5XhjghuVYuvvYWnSFpnvW",
  "amount": 90,
  "priceUsd": 6.002467911111111,
  "solVolume": 2.956,
  "volume": 540.22,
  "type": "sell",
  "wallet": "F7R61te4Ac8xZ4pfkJUdF6iaaHy9tnM8nVRUPv8H8EMi",
  "time": 1760201288835,
  "program": "raydium",
  "token": {
    "from": { "name": "OFFICIAL TRUMP", "symbol": "TRUMP", "amount": 90 },
    "to":   { "name": "USD Coin",        "symbol": "USDC",  "amount": 540.22 }
  }
}

巨鲸提醒

按美元成交量过滤接收的交易,当大额买入或卖出发生时触发巨鲸提醒:

const WHALE_THRESHOLD_USD = 10000; // $10k+

ws.onmessage = (event) => {
  const msg = JSON.parse(event.data);
  if (msg.type !== "message") return;

  msg.data.forEach(tx => {
    if (tx.volume >= WHALE_THRESHOLD_USD) {
      const side = tx.type === "buy" ? "🟢 WHALE BUY" : "🔴 WHALE SELL";
      console.log(`${side} — $${tx.volume.toLocaleString()} by ${tx.wallet}`);
      // trigger your alert: push notification, Discord webhook, etc.
    }
  });
};

在上线时检测狙击买入

结合交易时间、代币创建时间和交易金额筛选早期买入。这是活动筛选条件，不能单独证明钱包由机器人控制：

let launchTime = null; // First message sets the starting time.
const SNIPER_WINDOW_MS = 10_000; // first 10 seconds

ws.onmessage = (event) => {
  const msg = JSON.parse(event.data);
  if (msg.type !== "message") return;

  msg.data.forEach(tx => {
    if (!launchTime) launchTime = tx.time;

    const ageMs = tx.time - launchTime;
    const isEarly = ageMs < SNIPER_WINDOW_MS;

    if (isEarly && tx.type === "buy") {
      console.log(`🎯 Early buy (${(ageMs / 1000).toFixed(1)}s after launch)`);
      console.log(`   Wallet: ${tx.wallet}`);
      console.log(`   Amount: $${tx.volume.toFixed(2)}`);
    }
  });
};

跟单触发器

按钱包地址筛选交易，并将匹配的活动发送到告警处理器：

// Wallets you want to copy-trade
const WATCHED_WALLETS = new Set([
  "FV1r15rbNKkJanXLheoJA7fXEq6NDuMJ3bukXuhJWyV1",
  "4Rz5xqikxtZ2s7wE9uQ6n2oLXQi6K65XGoYpKxf24Hqo"
]);

ws.onmessage = (event) => {
  const msg = JSON.parse(event.data);
  if (msg.type !== "message") return;

  msg.data.forEach(tx => {
    if (WATCHED_WALLETS.has(tx.wallet) && tx.type === "buy") {
      console.log(`📡 Copy-trade trigger: ${tx.wallet.slice(0, 8)}... bought $${tx.volume.toFixed(2)}`);
      // → call your swap API here
    }
  });
};

完整的实时交易推送(带重连)

此示例演示断线重连和重新加入房间。心跳及认证处理见连接指南：

function startTradeFeed(token, onTrade) {
  let ws;
  let reconnectTimeout;

  function connect() {
    ws = new WebSocket("wss://datastream.solanatracker.io/YOUR_API_KEY");

    ws.onopen = () => {
      console.log(`Subscribed to trades for ${token}`);
      ws.send(JSON.stringify({ type: "join", room: `transaction:${token}` }));
    };

    ws.onmessage = (event) => {
      const msg = JSON.parse(event.data);
      if (msg.type === "message") {
        msg.data.forEach(onTrade);
      }
    };

    ws.onclose = () => {
      console.log("Disconnected — reconnecting in 3s");
      reconnectTimeout = setTimeout(connect, 3000);
    };

    ws.onerror = (err) => {
      console.error("Stream error:", err.message);
      ws.close();
    };
  }

  connect();

  return () => {
    clearTimeout(reconnectTimeout);
    ws?.close();
  };
}

// Usage
const stop = startTradeFeed(
  "6p6xgHyF7AeE6TZkSmFsko444wqoP15icUSqi2jfGiPN",
  (tx) => {
    const side = tx.type === "buy" ? "BUY " : "SELL";
    console.log(`${side} $${tx.volume.toFixed(2)} — ${tx.wallet.slice(0, 8)}...`);
  }
);

// Stop later: stop()
