Fastest free BOB RPC, live no-key EVM endpoint latency
HTTP round-trip latency for the `eth_getBlockByNumber(\"latest\", false)` method against every free, no-key public BOB EVM endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , dRPC leads rpc latency at 302 ms (p50, 24h) on Fastest free BOB RPC, live no-key EVM endpoint latency. Source: OpenChainBench, https://openchainbench.com/benchmarks/bob-rpc.

BOB (Build on Bitcoin) is an OP Stack hybrid L2 (chain 60808) that bridges Bitcoin and Ethereum, enabling Bitcoin DeFi with EVM smart contracts and native BTC collateral, ETH gas token, ~2 s block cadence, settlement on Ethereum. Integrated with Babylon BTC staking and leading Bitcoin LSTs. The 2026-08-03 audit confirms 4 clean keyless providers: the BOB official endpoint (rpc.gobob.xyz), Tenderly Gateway (bob.gateway.tenderly.co), dRPC (bob.drpc.org), and Thirdweb (60808.rpc.thirdweb.com). Excluded: Ankr (no bob route), Alchemy (key required), QuickNode (key required).
Methodology
Per-chain member of the RPC latency cluster, extended to BOB. We measure the round-trip latency of a single, identical JSON-RPC call (`eth_getBlockByNumber(\"latest\", false)`) against every no-key public BOB endpoint that sustains continuous probing, 4 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 a BOB-scaled staleness gap (20 blocks at BOB's ~2 s block time). The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the BOB-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free BOB RPC right now?
dRPC currently leads at 302 ms (`eth_getBlockByNumber("latest", false)` p50 over the last 24h), measured against 4 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 BOB RPCs work without an API key?
4 endpoints sustain continuous keyless probing: the BOB official endpoint (rpc.gobob.xyz), Tenderly Gateway (bob.gateway.tenderly.co), dRPC (bob.drpc.org), and Thirdweb (60808.rpc.thirdweb.com). Every listed endpoint was live-verified with a `eth_getBlockByNumber` POST returning a parsable response before inclusion.
Does the fastest BOB 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 BOB 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.
