Free HyperEVM RPC Endpoint
Chain ID 999 · HYPE · multi-region with automatic failover
HyperEVM (Chain ID 999) is Hyperliquid's EVM execution layer for on-chain perps and DeFi primitives. NodeFlare runs managed HyperEVM nodes — a chain most RPC providers don't support yet.

Built for HyperEVM
Perp DEXs, vaults, and DeFi primitives on Hyperliquid. Every request routes to the nearest healthy node, with automatic failover and no per-request throttling — the gaps public endpoints leave.
Dedicated HyperEVM RPC node — your own path, not a shared pool
NodeFlare runs its own dedicated HyperEVM node on bare-metal — not a reseller of Alchemy or Infura, and not a shared free-for-all pool. A free or paid key gives you a dedicated endpoint path with your own rate limits, no per-request throttling, and full access to heavy methods (eth_getLogs, trace_*, debug_*) — your own HyperEVM RPC without running the node yourself.
HyperEVM RPC — FAQ
What is HyperEVM's chain ID?
HyperEVM's chain ID is 999 (hex 0x3e7). Its native currency is HYPE and its block explorer is purrsec.com. You can connect with NodeFlare's free public RPC at https://rpc.nodeflare.app/hl/public — no API key required.
How do I add HyperEVM to MetaMask?
In MetaMask, open the network menu → "Add a network" → "Add a network manually", then enter — Network name: HyperEVM; New RPC URL: https://rpc.nodeflare.app/hl/public; Chain ID: 999; Currency symbol: HYPE; Block explorer URL: https://purrsec.com. Save, then switch to HyperEVM. The endpoint is free and needs no account.
What is the HyperEVM RPC URL?
NodeFlare's public HyperEVM RPC URL is https://rpc.nodeflare.app/hl/public over HTTPS and wss://rpc.nodeflare.app/hl/ws/public over WSS. No API key is required for the public endpoint.
Is the HyperEVM RPC free?
Yes. The public HyperEVM endpoint is free with no sign-up. A free API key unlocks higher rate limits, heavy methods, and a dedicated path — 2,000,000 compute units per month, no credit card.
What are the HyperEVM RPC rate limits?
The public endpoint is limited to 2 requests/second per IP. A free key gives 10 requests/second; paid plans scale to 500 req/s. Every plan includes all 22 supported chains.
Is NodeFlare a good HyperEVM RPC provider?
NodeFlare is an independent HyperEVM RPC provider that runs its own nodes — not a reseller or aggregator of third-party backends. The public endpoint is free with no sign-up; a free API key adds higher rate limits, WebSocket, and heavy methods (eth_getLogs, trace_*, debug_*) — 2,000,000 compute units per month, no credit card.
Is there a dedicated HyperEVM RPC node?
Yes. NodeFlare runs its own dedicated HyperEVM node(s), and every request is routed to the nearest healthy node with automatic failover. A free or paid key gives you a dedicated endpoint path with your own rate limits and full access to archive methods like eth_getLogs and debug_traceTransaction.
