# LaserStream WebSocket Methods

> Complete reference for LaserStream WebSocket subscription methods. Standard Solana subscriptions plus Helius extensions for real-time account, program, signature, slot, and log monitoring.

This is a comprehensive list of all WebSocket methods available through [LaserStream WebSocket](/rpc/websocket) — the standard Solana subscription methods plus Helius-specific extensions.

For detailed information on each method including parameters, results, and examples, please refer to the individual API reference pages.

<Tip>
  LaserStream WebSocket serves all Solana subscription methods on the same backend that powers [LaserStream gRPC](/laserstream), delivering up to 200 ms faster responses than the standard Agave RPC-based WebSocket implementation.
