Built for Mode
DeFi protocols and yield apps building on Mode. Every request routes to the nearest healthy node, with automatic failover and no per-request throttling — the gaps public endpoints leave.
Dedicated Mode RPC node — your own path, not a shared pool
NodeFlare runs its own dedicated Mode 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 Mode RPC without running the node yourself.

What is the Mode RPC URL?
NodeFlare's public Mode RPC URL is https://rpc.nodeflare.app/mode/public over HTTPS. No API key is required for the public endpoint.
Is the Mode RPC free?
Yes. The public Mode 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 Mode 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 Mode RPC provider?
NodeFlare is an independent Mode 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, and heavy methods (eth_getLogs, trace_*, debug_*) — 2,000,000 compute units per month, no credit card.
Is there a dedicated Mode RPC node?
Yes. NodeFlare runs its own dedicated Mode 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.
