# FluxRPC > FluxRPC is a high-performance RPC infrastructure provider for Solana and Fogo blockchains, offering ultra-low latency JSON-RPC endpoints, WebSocket subscriptions, and edge caching via Lantern. FluxRPC supports two networks: - **Solana** — Full Solana JSON-RPC 2.0 with sub-100ms global latency - **Fogo** — 100% SVM-compatible chain with 40ms block times, powered by the Firedancer client All standard Solana RPC methods work identically on both networks. The only difference is the endpoint URL. ## Endpoints - [Solana HTTP RPC](https://fluxrpc.com/docs/rpc): `https://eu.fluxrpc.com?key=` - [Solana WebSocket](https://fluxrpc.com/docs/websocket): `wss://ws.eu.fluxrpc.com` -
