Merlin Chain RPC endpoints: free public URLs by latency
HTTP round-trip latency for eth_getBlockByNumber against every available public Merlin Chain node, audited every 60 seconds from 3 regions.
TL;DR. As of , Merlin Official has the lowest median latency of the 2 free public Merlin Chain RPC endpoints measured, 148 ms (p50, 24h, 3 regions). Source: OpenChainBench, https://openchainbench.com/benchmarks/merlin-rpc. Chain ID 4200. 2 public endpoints, no key: rpc.merlinchain.io, merlin.drpc.org. Full URLs with their 24h median are listed below.

Merlin Chain is an EVM-compatible Bitcoin Layer 2 network (chain ID 4200) that uses ZK-Rollup technology to inherit Bitcoin security while enabling smart contracts and DeFi. It exposes a standard Ethereum JSON-RPC interface. Public EVM endpoints are available without an API key from Merlin Official, dRPC and BlockPI. Every provider was live-verified with consecutive eth_getBlockByNumber probes at launch.
Methodology
Merlin Chain: 2 free public RPC endpoints answering `eth_getBlockByNumber` every 60 seconds from us-east, eu-west and Singapore, ranked by 24h median. Merlin Official leads at 148 ms; the chain-official endpoint measures 148 ms. We measure the round-trip latency of a single eth_getBlockByNumber ("latest", false) call against every available public Merlin Chain node that sustains continuous probing: 2 providers live today, every 60 seconds, from us-east, eu-west and Singapore. The harness classifies every response (ok / http_err / jsonrpc_err / stale / timeout) with a standard EVM staleness gap. The cross-chain view lives on the parent rpc-capabilities benchmark; this page is the Merlin Chain-scoped answer with per-region breakdowns.

Frequently asked
Which Merlin Chain RPC endpoints work without an API key?
3 endpoints are probed on this chain: Merlin Official (rpc.merlinchain.io), dRPC (merlin.drpc.org) and BlockPI (merlin.blockpi.network). Every listed endpoint was live-verified with an eth_getBlockByNumber call returning a parsable block number before inclusion.
