 question: "dRPC vs PublicNode vs 1RPC, which no-key public RPC is fastest?"
 short_answer: |
-  OpenChainBench ranks dRPC, PublicNode and 1RPC alongside 12 other no-key public RPCs on identical eth_getBlockByNumber probes from three regions across 10 EVM chains. Aggregate leaders on the full 15-provider board are often chain-official gateways (Binance, Base, Avalanche) rather than the multi-chain trio, and 1RPC was delisted from the leaderboard 2026-07-09 for a sustained sub-13 percent success rate. Live per chain and per region ranking at openchainbench.com/benchmarks/rpc-capabilities.
+  Between the three providers, dRPC and PublicNode trade the top two spots by chain and region; 1RPC was delisted 2026-07-09 for a sustained sub-13% success rate and is pinned below the ranked table. On the wider 15-provider board, chain-official gateways (Binance, Base, Avalanche) often post faster aggregate p50.

-  {{best_name}} currently relays Polymarket trades the fastest at {{best_p50}} (p50, 24h) versus Polymarket's own CLOB WebSocket gateway, measured by cross correlating trade events on Polymarket and Codex on the same rotating basket of top 20 markets by 24 hour volume.
+  Polymarket's own CLOB WebSocket gateway is the canonical fastest source by definition (T0, sub-50ms from EU West) and is not a competing data provider. Among third-party data providers, Codex currently leads at {{p50:codex}} (p50, 24h) on the Polymarket tab, measured as lag from venue publish to provider relay; Codex indexes the onchain Polygon confirmation so its structural floor is roughly 2 seconds of block time. Live per-venue ranking at openchainbench.com/benchmarks/pm-data-freshness.

-  {{best_name}} currently posts the lowest warm book endpoint latency at {{best_p50}} (p50, 24h) across Polymarket, Kalshi, Limitless, Manifold and Myriad, measured live by OpenChainBench with a daily throttle ramp from 3 regions.
+  Myriad documents the tightest published rate limit in the cohort at 30 requests per 10 seconds. Polymarket has no hard 429 threshold at polite rates — its Cloudflare front queues bursts and adds latency instead of returning errors. Kalshi runs a documented token bucket per access tier. Live warm-book p50 latency and daily throttle-ramp results for all five venues at openchainbench.com/benchmarks/pm-rate-limits.
