Token transfers
某个 SPL 或 Token-2022 代币在任意钱包之间的所有转账。房间：transfer:{mint}。balances 列出该代币在此交易中的余额变化。不支持 SOL：请使用钱包房间或 transfer:So11111111111111111111111111111111111111112:{wallet}。添加 :enriched 获取代币元数据、美元价值和钱包身份。事件处于 processed 状态，尚未确认。

WebSocket example
const mint = "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"; // USDC
const room = `transfer:${mint}`; // or `${...}:enriched` for token metadata, USD values and wallet identities
const ws = new WebSocket("wss://datastream.solanatracker.io/YOUR_API_KEY");
ws.addEventListener("open", () => {
ws.send(JSON.stringify({ type: "join", room }));
});
ws.addEventListener("message", (event) => {
const msg = JSON.parse(event.data);
if (msg.type === "ping") return ws.send(JSON.stringify({ type: "pong" }));
if (msg.type !== "message") return;
const { signature, transfers, balances } = msg.data;
for (const t of transfers) {
console.log(signature, t.direction ?? "", t.uiAmount, t.mint, t.from.owner, "->", t.to.owner);
}
});
uiAmount。已在交易房间中推送的兑换中的转账不会再次发送；兑换的剩余部分（平台手续费、小费、付款）会带 swapTx: true 推送。历史加实时更新的用法请参阅转账指南。
