Cronos zkEVM (chain 388) is Crypto.com's zkEVM Layer 2 built on the zkSync Era stack, distinct from Cronos EVM. CRO is the bridged gas token. Three keyless endpoints are probed continuously: the Cronos official mainnet gateway (mainnet.zkevm.cronos.org), dRPC (cronos-zkevm.drpc.org), and Blast API.
Methodology
Per-chain member of the RPC latency cluster, extended to Cronos zkEVM. We measure the round-trip latency of a single, identical RPC call (`eth_getBlockByNumber`) against every no-key public Cronos zkEVM endpoint that sustains continuous probing, 3 providers at launch, every 60 seconds, from us-east, eu-west and Singapore. The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the Cronos zkEVM-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Cronos zkEVM RPC right now?
Cronos (Crypto.com) currently leads at 228 ms (`eth_getBlockByNumber` p50 over the last 24h), measured against 3 no-key providers probed every 60 seconds from us-east, eu-west and Singapore.
Which Cronos zkEVM RPCs work without an API key?
3 endpoints sustain continuous keyless probing: Cronos official, dRPC, and Blast API. Every endpoint was live-verified before inclusion.
Does the fastest Cronos zkEVM RPC change by region?
Often. The region tabs at the top of the page re-scope every number to a single origin.
How is Cronos zkEVM RPC latency measured here?
One identical JSON-RPC POST (`eth_getBlockByNumber`) every 60 seconds against each provider from each of 3 regions.
