Best WSS Endpoints for Polygon (2025)

Why it matters

Polygon is sensitive to latency variance; consistent endpoints improve inclusion probability.

How to test

Run WSS Latency Test at different hours and compare variance, not just median.

Benchmark checklist

• Capture connection setup time, p50/p95 latency, and jitter.
• Note throttling, dropped subscriptions, or slow status updates.
• Repeat the same test weekly and after each major Polygon upgrade.

Rotation & documentation

1. Alert at variance > 50 ms or median > 180 ms.
2. Switch to standby endpoint and log the time plus reason in Ops Pulse.
3. Update the Knowledge Base so new operators know which providers are healthy.

Endpoint mini-leaderboard

Post this snapshot next to your liquidity tracker so rotations remain data-driven.

Integrate with FRB guard rails

• Tie endpoint health to refund thresholds—pause routes when latency correlates with failed bundles.
• Link benchmarks from the Polygon MEV guide so strategy notes stay current.
• Share weekly snapshots with compliance as part of your diligence pack.

FAQ

Do I need more than two providers?
Ideally yes—keep a tertiary provider on ice for backup.

Should I use region-specific endpoints?
If you run infra in multiple regions, benchmark from each region separately and match nodes to local endpoints.

Can I automate the test?
Yes. Pair the browser benchmark with scripted checks feeding into your monitoring stack for 24/7 coverage.

What if variance stays high even after rotation?
Pause the route, run benchmarks from a different POP, and verify relay health. Resume only when both endpoint and builder metrics stabilize.
