Arbitrum Nova is an AnyTrust chain (chain 42170) built on the Nitro stack, optimised for high-throughput gaming and social applications with ultra-low transaction costs. Unlike Arbitrum One's full rollup model, Nova posts minimal data on-chain via a Data Availability Committee, achieving sub-cent fees. The 2026-08-04 audit confirms 3 clean keyless providers: PublicNode (arbitrum-nova-rpc.publicnode.com), dRPC (arbitrum-nova.drpc.org), and Thirdweb (42170.rpc.thirdweb.com). Excluded: Ankr (no Nova route), Alchemy (key required).
Methodology
Per-chain member of the RPC latency cluster, extended to Arbitrum Nova. We measure the round-trip latency of a single, identical JSON-RPC call (`eth_getBlockByNumber("latest", false)`) against every no-key public Arbitrum Nova endpoint that sustains continuous probing, 3 providers measured, every 60 seconds, from us-east, eu-west and Singapore. The harness classifies every response (ok / http_err / jsonrpc_err / stale / timeout) with an Arbitrum Nova-scaled staleness gap (20 blocks at Arbitrum Nova's ~1 s block time). The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the Arbitrum Nova-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Arbitrum Nova RPC right now?
PublicNode currently leads at 146 ms (`eth_getBlockByNumber("latest", false)` p50 over the last 24h), measured against 3 no-key providers probed every 60 seconds from us-east, eu-west and Singapore. The leaderboard re-sorts continuously against fresh Prometheus samples. Use the region tabs to see the leader from the origin closest to your deployment.
Which Arbitrum Nova RPCs work without an API key?
3 endpoints sustain continuous keyless probing: PublicNode (https://arbitrum-nova-rpc.publicnode.com), dRPC (https://arbitrum-nova.drpc.org), and Thirdweb (https://42170.rpc.thirdweb.com). Every listed endpoint was live-verified with a `eth_getBlockByNumber` POST returning a parsable response before inclusion.
Does the fastest Arbitrum Nova RPC change by region?
Often. Public infra concentrates in specific regions; a gateway that wins from Amsterdam can lose from Singapore by multiples. 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 Arbitrum Nova RPC latency measured here, technically?
One identical `eth_getBlockByNumber("latest", false)` POST every 60 seconds against each provider from each of 3 regions, using the same plain HTTP client the rest of the RPC cluster uses. 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 (`ok` / `http_err` / `jsonrpc_err` / `stale` / `timeout`) so an endpoint stuck on an old head or returning errors behind HTTP 200 is never ranked as fastest.
