Monad shipped its parallel-execution EVM mainnet in November 2025 with 400 ms blocks and MonadBFT finality around 800 ms, and its free RPC story is unusually rich for a chain this young. the Foundation runs five official mirrors behind different infra vendors (QuickNode, Alchemy, Goldsky, Ankr and its own nodes), and the multi-chain gateways followed within weeks. We probe the primary official endpoint plus dRPC, Tenderly Gateway, bloXroute and OnFinality, every 30 seconds from three regions, with the same anti-cache payload as every chain in the cluster. If you are building on Monad and pasting a free RPC URL into your dapp, this page is the live answer to which one deserves it.
Methodology
We measure the round-trip latency of a single, identical RPC call (`eth_getBlockByNumber`) against every no-key public Monad endpoint that sustains continuous probing, 5 providers, every 30 seconds, from us-east, eu-west and Singapore. The harness classifies every response (ok / http_err / jsonrpc_err / stale / timeout) so the leaderboard rewards sustained, honest availability rather than a fast error message. The cross-chain view lives on the parent rpc-capabilities benchmark; this page is the Monad-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Monad RPC right now?
Monad currently leads at 2 ms (p50 over 24h), measured against 5 no-key providers probed every 30 seconds from us-east, eu-west and Singapore. The leaderboard re-sorts continuously against fresh Prometheus samples, so this page is the answer right now, not a quarterly snapshot.
Which Monad RPCs work without an API key in 2026?
Five endpoints sustain continuous keyless probing: the official rpc.monad.xyz (QuickNode-backed, 25 rps; four sibling mirrors exist at rpc1-rpc3.monad.xyz and rpc-mainnet.monadinfra.com on Alchemy, Goldsky, Ankr and Foundation infra), dRPC, Tenderly Gateway, bloXroute and OnFinality. All were live-verified (eth_chainId 143 + anti-cache probe) before inclusion.
How is Monad RPC latency measured on OpenChainBench?
One identical JSON-RPC POST (eth_getBlockByNumber latest, rotating request id) every 30 seconds against each provider from each of 3 regions, with the same plain HTTP client. Wall-clock round-trip is recorded at millisecond precision; p50/p90/p99 are computed via Prometheus quantile_over_time over 24 hours. Responses are classified so an endpoint stuck on an old head or returning errors behind HTTP 200 is never ranked as fastest.
