Scroll runs the same 4-gateway field as Linea (PublicNode, dRPC, 1RPC, Tenderly), making the two chains a natural controlled experiment: same providers, same probe, different chain infrastructure. The differences you see between this page and the Linea leaderboard are the chains, not the gateways. Probes every 15 seconds, three regions, stale-head detection against the cross-provider tip.
Methodology
Per-chain member of the RPC latency cluster. We measure the round-trip latency of a single, identical RPC call (`eth_blockNumber`) against every no-key public Scroll endpoint that sustains continuous probing, 4 providers, every 15 seconds, from us-east, eu-west and Singapore. The harness also classifies every response (ok / http_err / jsonrpc_err / stale / timeout) and audits archive depth every 5 minutes, 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 Scroll-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Scroll RPC right now?
dRPC currently leads at 24 ms (`eth_blockNumber` p50 over the last 24h), measured against 4 no-key providers probed every 15 seconds from us-east, eu-west and Singapore. The leaderboard re-sorts continuously against fresh Prometheus samples, so the answer on this page is the answer right now, not a quarterly snapshot. Use the region tabs to see the leader from the origin closest to your deployment.
Which Scroll RPCs work without an API key?
The 4 providers on this page: PublicNode, dRPC, 1RPC, Tenderly. Every (provider, chain) pair was live-verified no-key before inclusion, and anything that key-gates, region-blocks or rate-limits below our 15-second cadence is excluded rather than listed with an asterisk.
Does the fastest Scroll RPC change by region?
Frequently. The headline number averages three probe origins (us-east, eu-west, Singapore), but per-region leaders regularly diverge, a gateway that wins from Virginia can lose from Singapore by multiples. The region tabs at the top of the page re-scope every number on the page to a single origin; pick the one closest to where your requests actually originate.
How is Scroll RPC latency measured here?
One identical JSON-RPC POST (`eth_blockNumber`) every 15 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 (`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. The harness is open source and every number on this page is a public Prometheus query you can run yourself.
Which free RPC should I default to on Scroll?
Start from the current leader above, then check its per-region row for the origin closest to your deployment. With a 4-provider field the honest answer changes more often than on Ethereum, so a primary-plus-fallback pair (the top two on this page) is the resilient configuration rather than any single hardcoded URL.
