title: Fastest free Abstract RPC, live no-key EVM endpoint latency
seo_title: "Fastest free Abstract RPC 2026"
seo_description: "{{best_name}} leads free Abstract RPC at {{best_p50}} (`eth_getBlockByNumber` p50, 24h). 3 no-key providers measured every 60s from 3 regions."
subtitle: HTTP round-trip latency for the `eth_getBlockByNumber(\"latest\", false)` method against every free, no-key public Abstract EVM endpoint, audited every 60 seconds from 3 regions.

seo_intro: |
Abstract is a ZK Stack validium L2 (chain 2741) built by the Abstract Foundation, optimised for consumer applications and NFTs, ETH gas token, ~2 s block cadence, ZK proof settlement onto Ethereum. The 2026-08-02 audit confirms 3 clean keyless providers: the Abstract Foundation official endpoint (api.mainnet.abs.xyz), dRPC (abstract.drpc.org), and Thirdweb (abstract.rpc.thirdweb.com). Excluded: Ankr (no abstract route on public tier), Alchemy (key required), Infura (key required), QuickNode (key required).

abstract: |
Per-chain member of the RPC latency cluster, extended to Abstract.
We measure the round-trip latency of a single, identical JSON-RPC call
(`eth_getBlockByNumber(\"latest\", false)`) against every no-key public
Abstract 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 an Abstract-scaled staleness gap (20 blocks
at Abstract's ~2 s block time). The cross-chain view
lives on the parent `rpc-capabilities` benchmark; this page is the
Abstract-scoped answer with per-region breakdowns as a first-class
dimension.

methodology:
- "Cadence: every 60 seconds per provider, from each of 3 probe regions (us-east Virginia, eu-west Amsterdam, sgp Singapore). Headline p50/p90/p99 aggregate across all 3 regions via Prometheus `avg(quantile_over_time(...))`; per-region breakdowns are first-class on this page via the region tabs."
- "Payload: `{\"jsonrpc\":\"2.0\",\"id\":<rotating>,\"method\":\"eth_getBlockByNumber\",\"params\":[\"latest\", false]}`. Plain HTTP POST, identical for every endpoint, no API key in any request. Non-cacheable by design: the rotating id defeats edge caches that would answer a bare head query without touching a node."
- "Latency: client-side round-trip delta in milliseconds, exposed as both a gauge and a histogram (buckets 50 ms → 10 s), so percentiles are computed via Prometheus `quantile_over_time` over the last 24 hours."
- "Call-result classification: `ok` (HTTP 200 + non-empty result with a parsable hex block number), `http_err`, `jsonrpc_err` (HTTP 200 carrying an error body), `stale` (more than 20 blocks behind the cross-provider tip), `timeout`. Latency without reliability is a misleading ranking signal."
- "This page is part of the per-chain RPC cluster derived from the cross-chain [rpc-capabilities](https://openchainbench.com/benchmarks/rpc-capabilities) benchmark; the identical harness, cadence and exclusion rules apply on every chain."
- "Chain scope: every query on this page is pinned to `chain=\"abstract\"`. Provider coverage at launch: 3 no-key endpoints."

findings:
- "{{best_name}} currently leads free Abstract RPC at {{best_p50}} (`eth_getBlockByNumber` p50, 24h) across 3 measured providers."

faq:
- q: "What is the fastest free Abstract RPC right now?"
a: "{{best_name}} currently leads at {{best_p50}} (`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."
- q: "Which Abstract RPCs work without an API key?"
a: "3 endpoints sustain continuous keyless probing at launch: the Abstract Foundation official endpoint (api.mainnet.abs.xyz), dRPC (abstract.drpc.org), and Thirdweb (abstract.rpc.thirdweb.com). Every listed endpoint was live-verified with a `eth_getBlockByNumber` POST returning a parsable response before inclusion."
- q: "Does the fastest Abstract RPC change by region?"
a: "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."
- q: "How is Abstract RPC latency measured here, technically?"
a: "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."
