Edge Tier

Production GoldRush JSON-RPC with archive depth, debug and trace, sub-100ms p50 latency, and an SLA.

The Edge tier is the production endpoint for GoldRush JSON-RPC. It runs from regional edge POPs in front of an analytics-driven multi-provider router, with archive depth, the debug_* and trace_* namespaces, and an SLA.

The Edge layer:

1. Authenticates the request, so invalid keys never hit the upstream.
2. Caches safe-to-cache reads (e.g. eth_getBlockByNumber for finalized blocks) at the edge.
3. Routes the call to whichever upstream provider currently scores highest on cost and performance for that specific (chain, method) route. Scores are continuously updated from rolling-window success rate, latency, error class, and cost analytics.
4. Re-routes on failure to the next-best provider, and feeds the failure back into the score so the routing table self-corrects in seconds.

The result: lower p99 latency than any single provider, and no single-vendor dependency.

Archive depth

Edge serves historical state and traces back to the chain’s earliest available archive block. Depth varies by chain. See debug and trace for the per-chain matrix.

SLA and rate limits

• Uptime SLA: 99.9% per calendar month
• Rate limit: configurable per account; defaults to 1,000 RPS
• Burst: 2× the configured RPS for up to 60 seconds
