Built for Unichain
DEX integrations, MEV-aware trading, and liquidity tooling on Unichain. Every request routes to the nearest healthy node, with automatic failover and no per-request throttling — the gaps public endpoints leave.
Dedicated Unichain RPC node — your own path, not a shared pool
NodeFlare runs its own dedicated Unichain 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 Unichain RPC without running the node yourself.
