Fastest free Cyber RPC, live no-key EVM endpoint latency
HTTP round-trip latency for the `eth_getBlockByNumber(\"latest\", false)` method against every free, no-key public Cyber Network EVM endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , Cyber Network leads rpc latency at 167 ms (p50, 24h) on Fastest free Cyber RPC, live no-key EVM endpoint latency. Source: OpenChainBench, https://openchainbench.com/benchmarks/cyber-rpc.

Cyber Network is an OP Stack L2 (chain 7560) operated by Cyber, a social-layer chain for SocialFi and Web3 social graphs, ETH gas token, ~2 s block cadence, blob calldata settlement on Ethereum. The 2026-08-02 audit confirms 3 clean keyless providers: Cyber official (rpc.cyber.co), AltLayer (cyber.alt.technology), and Thirdweb (7560.rpc.thirdweb.com). Excluded: dRPC (no cyber route), Blast API (no listing), Alchemy (key required).
Methodology
Per-chain member of the RPC latency cluster, extended to Cyber Network. We measure the round-trip latency of a single, identical JSON-RPC call (`eth_getBlockByNumber(\"latest\", false)`) against every no-key public Cyber Network endpoint that sustains continuous probing, 3 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) with a Cyber-scaled staleness gap (20 blocks at Cyber's ~2 s block time). The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the Cyber-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Cyber Network RPC right now?
Cyber Network currently leads at 167 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 Cyber Network RPCs work without an API key?
3 endpoints sustain continuous keyless probing at launch: Cyber official (rpc.cyber.co), AltLayer (cyber.alt.technology), and Thirdweb (7560.rpc.thirdweb.com, chain-ID URL). Every listed endpoint was live-verified with a `eth_getBlockByNumber` POST returning a parsable response before inclusion.
Does the fastest Cyber Network 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 Cyber Network 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.
