Solana RPC URLs and Endpoints - Helius Docs

Solana RPC Endpoints

High-performance RPC endpoints providing full Solana API compatibility with enhanced reliability and throughput. These endpoints support all Solana JSON-RPC methods and now use staked connections by default for all paid plans, providing optimal transaction landing rates:

• Mainnet: https://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY
• Mainnet (Gatekeeper Beta): https://beta.helius-rpc.com/?api-key=YOUR_API_KEY
• Devnet: https://devnet.helius-rpc.com/?api-key=YOUR_API_KEY

Want the fastest experience? Try our Gatekeeper (Beta) endpoint for significantly lower latency. Your API key works on both standard and beta endpoints without any changes.

Secure RPC Endpoints

Secure RPC URLs are specifically masked and IP rate-limited at 5 TPS, making them safe to use directly from frontend applications while protecting your API keys:

• Mainnet: https://abc-456-fast-mainnet.helius-rpc.com
• Devnet: https://123-xyz-fast-devnet.helius-rpc.com

LaserStream WebSocket Endpoints

LaserStream WebSocket serves both the standard Solana WebSocket subscription methods and Helius’s extensions (transactionSubscribe, enhanced accountSubscribe) on a single unified endpoint per network:

• Mainnet: wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY
• Mainnet (Gatekeeper Beta): wss://beta.helius-rpc.com/?api-key=YOUR_API_KEY
• Devnet: wss://devnet.helius-rpc.com/?api-key=YOUR_API_KEY

LaserStream WebSocket reduces latency by ~200 ms compared to standard Agave RPC-based WebSockets. Standard Solana methods are available on all plans; the Helius extensions require a Developer, Business, or Professional plan. No code changes required.

Key Features

• Backed by LaserStream: shares its backend with LaserStream gRPC, delivering data up to 200 ms faster than standard Agave RPC-based WebSockets
• Standard Solana subscriptions (all plans): accountSubscribe, programSubscribe, signatureSubscribe, slotSubscribe, logsSubscribe, and more — fully compatible with Solana’s WebSocket API
• Helius extensions (Developer, Business, Professional plans): transactionSubscribe and an enhanced accountSubscribe with advanced filtering
• Connection management: WebSockets have a 10-minute inactivity timer; implement health checks and send pings every minute to keep connections alive
• Best for: apps that need to monitor account changes, track transactions, or get real-time updates on Solana activity

Staked Connection Endpoints (Deprecated)

The staked endpoint (staked.helius-rpc.com) is deprecated. Use the regular endpoint (mainnet.helius-rpc.com), which uses staked connections by default for all paid plans.

• Cost: 1 credit per sendTransaction request (reduced from 10 credits)
• Automatic optimization: All transactions are sent over optimized network infrastructure (Asia, Europe, and North America)
• Higher landing rates: Guaranteed access to staked connections during congestion
• No code changes: Existing apps automatically benefit from staked connections
