WebSocket RPC

Litecoin WebSocket RPC

Stream Litecoin data in real time over a WebSocket connection — new blocks, pending transactions, and contract events — instead of polling. Every SwiftNodes plan includes a Litecoin WebSocket endpoint alongside HTTP, with flat-rate pricing and no KYC.

Endpoint

wss://rpc.swiftnodes.io/ws/ltc?key=YOUR_API_KEY

The HTTP endpoint for Litecoin is https://rpc.swiftnodes.io/rpc/ltc?key=YOUR_API_KEY. One API key works for both, and across all 75+ supported chains.

Subscribe to Litecoin in real time

import { Connection } from "@solana/web3.js";

const conn = new Connection("https://rpc.swiftnodes.io/rpc/ltc?key=YOUR_API_KEY", {
  wsEndpoint: "wss://rpc.swiftnodes.io/ws/ltc?key=YOUR_API_KEY",
});

// Subscribe to new slots on Litecoin
const subId = conn.onSlotChange((slot) => console.log("slot", slot.slot));

What you can subscribe to

  • Slot and root updates — track chain progress in real time
  • Account changes — get notified when an account's data updates
  • Program and signature subscriptions for live app state

Litecoin is a Layer 1 (UTXO, Scrypt proof-of-work), with ~~2.5 minutes block times and probabilistic — ~15 minutes (6 confirmations) for high-value settlement finality. That cadence sets how frequently new-block subscriptions fire.

Frequently asked questions

Does SwiftNodes support Litecoin WebSocket?

Yes. Every Litecoin plan includes a WebSocket (wss://) endpoint alongside HTTP, with no separate add-on. Connect to wss://rpc.swiftnodes.io/ws/ltc?key=<key> and open subscriptions immediately.

What is the Litecoin WebSocket URL?

wss://rpc.swiftnodes.io/ws/ltc?key=YOUR_API_KEY — replace YOUR_API_KEY with the key from your dashboard. The matching HTTP endpoint is https://rpc.swiftnodes.io/rpc/ltc?key=YOUR_API_KEY.

Is there a message rate limit on the WebSocket?

Yes — WebSocket throughput scales with your plan (1 msg/s on Free up to 250 msg/s on Pro), with concurrent-connection limits per plan. Within those limits, subscriptions stream in real time.

See the full Litecoin RPC page for chain details, or the WebSocket docs for the complete method list.
