Fastest free Fantom RPC, live no-key endpoint latency
HTTP round-trip latency for eth_getBlockByNumber against every free, no-key public Fantom EVM endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , Fantom Foundation leads rpc latency at 194 ms (p50, 24h) on Fastest free Fantom RPC, live no-key endpoint latency. Source: OpenChainBench, https://openchainbench.com/benchmarks/fantom-rpc.

Fantom Opera (chain 250) is a DAG-based EVM-compatible L1 using Lachesis aBFT consensus, delivering ~1-2 second finality with FTM as the gas token. Five keyless endpoints are probed continuously: the Fantom Foundation official gateway (rpcapi.fantom.network), dRPC (fantom.drpc.org), Ankr (rpc.ankr.com/fantom), Thirdweb (250.rpc.thirdweb.com), and Blast API (fantom-mainnet.public.blastapi.io).
Methodology
Per-chain member of the RPC latency cluster, extended to Fantom. We measure the round-trip latency of a single, identical RPC call (`eth_getBlockByNumber`) against every no-key public Fantom endpoint that sustains continuous probing, 5 providers at launch, every 60 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 availability rather than fast error messages. The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the Fantom-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Fantom RPC right now?
Fantom Foundation currently leads at 194 ms (`eth_getBlockByNumber` p50 over the last 24h), measured against 5 no-key providers probed every 60 seconds from us-east, eu-west and Singapore. The leaderboard re-sorts continuously against fresh Prometheus samples.
Which Fantom RPCs work without an API key?
5 endpoints sustain continuous keyless probing at launch: Fantom Foundation, dRPC, Ankr, Thirdweb, Blast API. Every listed endpoint was live-verified before inclusion.
Does the fastest Fantom RPC change by region?
Often. The region tabs at the top of the page re-scope every number to a single origin; pick the one closest to where your requests originate.
How is Fantom RPC latency measured here?
One identical JSON-RPC POST (`eth_getBlockByNumber`) every 60 seconds against each provider from each of 3 regions. Responses are classified so an endpoint stuck on an old head or returning errors is never ranked as fastest.
