# SwiftNodes

> SwiftNodes is a multi-chain blockchain RPC provider. Developers point their dApps, bots, and indexers at SwiftNodes HTTP and WebSocket endpoints instead of running their own nodes or using Alchemy/QuickNode/Infura. One API key works across 75+ EVM and non-EVM chains. Differentiators: flat-rate monthly pricing (no per-request fees, no compute units), crypto payments (ETH/BNB/USDT/USDC), no KYC at any tier, and broad chain coverage including Bitcoin family, Cosmos, Polkadot, Solana, Sui, Aptos, TRON, and Starknet.

## Endpoints

- HTTP: `https://rpc.swiftnodes.io/rpc/<chain>?key=<API_KEY>`
- WebSocket: `wss://rpc.swiftnodes.io/ws/<chain>?key=<API_KEY>`
- A public `demo` key works for evaluation: `https://rpc.swiftnodes.io/rpc/eth?key=demo` (free-tier rate limits, shared). Note: slugs are short codes — Ethereum is `eth`, not `ethereum`.
