Overview
Polygon latency gotchas and WSS recommendations.
Key points
- Clear definitions and when this topic matters for MEV practitioners.
- Step-by-step guidance you can apply inside FRB today.
- Risk notes and guardrails (no profitability guarantees).
Walkthrough
- Setup — ensure reliable RPC/WSS endpoints and time-sync.
- Configuration — start with simulation/canary, set slippage and budget caps.
- Execution — prefer private bundles when available; monitor inclusion and adjust.
- Review — log outcomes, tweak filters, and iterate conservatively.
Risk & compliance
MEV is experimental and high-risk. Slippage, inclusion uncertainty and reorgs can cause losses. You are responsible for legality in your jurisdiction.
Next steps
Use the FRB agent to scan mempools and submit private bundles with custody preserved.

Comments
Hope to see more examples on Polygon.
This helped me fix my inclusion issues last week.
Any tips for tuning slippage caps on volatile pairs?
The checklist was super helpful—please add a section on reorgs.
Clear and concise—thanks for the safety notes!
Please cover bundle failure modes and retries.
Great primer on private bundles and risks.
Adding a “pitfalls” section was a nice touch.
I tried this with a canary size and it worked as expected.
Inclusion rate improved after moving to private bundles.
Could you compare relay options in more detail?
Would love a follow-up on simulation best practices.
Would love a video walkthrough for setup.
Could you share recommended WSS providers?
Could you compare relay options in more detail?
Could you compare relay options in more detail?
The TL;DR makes it easy to share with teammates.
