Built for Soneium
Consumer, gaming, and IP/entertainment apps on Soneium. Every request routes to the nearest healthy node, with automatic failover and no per-request throttling — the gaps public endpoints leave.
Dedicated Soneium RPC node — your own path, not a shared pool
NodeFlare runs its own dedicated Soneium 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 Soneium RPC without running the node yourself.
