Real-Time Streaming with WebSockets 🚀

Nischit Pradhan

We’re thrilled to announce a powerful new addition to our RPC toolkit: native WebSocket support for Plume Mainnet (chain ID 98866) and Testnet (chain ID 98867). Now you can subscribe to live block events and react instantly as new blocks are produced—no polling required

• WebSocket Endpoints
  • Mainnet:
    wss://98866.rpc.thirdweb.com/ws/<client_id>
  • Testnet
    wss://98867.rpc.thirdweb.com/ws/<client_id>
    
• Real-Time Block Events
  Subscribe once and receive a continuous stream of block headers and payloads as they’re finalized on-chain.

1. Instant Data
   No more waiting for HTTP responses—get block notifications the moment they happen.
2. Lower Latency
   Maintain a persistent socket connection instead of hammering REST endpoints.
3. Scalability
   Stream to multiple clients or services without spinning up extra request handlers.

1. Generate or retrieve your <client_id> from your Thirdweb dashboard.
2. Connect via your favorite WebSocket library:

import WebSocket from "ws";
 
const chainId = "98866"; // or "98867" for Testnet
const clientId = "<your_client_id>";
const wsUrl = `wss://${chainId}.rpc.thirdweb.com/ws/${clientId}`;
 
const ws = new WebSocket(wsUrl);
 
ws.on("open", () => {
  console.log("Connected to Plume WebSocket!");
  // Subscribe to new block events
  ws.send(
    JSON.stringify({
      id: 1,
      jsonrpc: "2.0",
      method: "eth_subscribe",
      params: ["newHeads"],
    }),
  );
});
 
ws.on("message", (data) => {
  const event = JSON.parse(data);
  console.log("New block received:", event);
});

3. Handle Events
   Every newHeads message includes block number, hash, timestamp, and parent hash—ready for indexing, alerts, or analytics.

• More Chains Coming Soon!
  We’re actively working on extending WebSocket support across additional networks. Stay tuned for announcements!
