Built for Mantle
DeFi, restaking-adjacent apps, and yield products on Mantle. Every request routes to the nearest healthy node, with automatic failover and no per-request throttling — the gaps public endpoints leave.
Dedicated Mantle RPC node — your own path, not a shared pool
NodeFlare runs its own dedicated Mantle 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 Mantle RPC without running the node yourself.
Mantle RPC — FAQ
What is Mantle's chain ID?
Mantle's chain ID is 5000 (hex 0x1388). Its native currency is MNT and its block explorer is mantlescan.xyz. You can connect with NodeFlare's free public RPC at https://rpc.nodeflare.app/mantle/public — no API key required.
How do I add Mantle to MetaMask?
In MetaMask, open the network menu → "Add a network" → "Add a network manually", then enter — Network name: Mantle; New RPC URL: https://rpc.nodeflare.app/mantle/public; Chain ID: 5000; Currency symbol: MNT; Block explorer URL: https://mantlescan.xyz. Save, then switch to Mantle. The endpoint is free and needs no account.
What is the Mantle RPC URL?
NodeFlare's public Mantle RPC URL is https://rpc.nodeflare.app/mantle/public over HTTPS. No API key is required for the public endpoint.
Is the Mantle RPC free?
Yes. The public Mantle 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 Mantle 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 Mantle RPC provider?
NodeFlare is an independent Mantle 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 Mantle RPC node?
Yes. NodeFlare runs its own dedicated Mantle 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.
