Overview
Most failures trace back to latency variance, configuration gaps, or invalid assumptions.
Checklist
- Verify relay reachability and fallback.
- Confirm triggering transaction reference.
- Tighten or loosen caps where appropriate.
- Compare private vs public outcomes on a small sample.
Logs & metrics
- Record arrival deltas and inclusion percent. Iterate conservatively.

Backrun example clarified a lot for me.
Please cover bundle failure modes and retries.
Could you compare relay options in more detail?
Clear and concise—thanks for the safety notes!
Could you share recommended WSS providers?
Any tips for tuning slippage caps on volatile pairs?
I set tighter caps and avoided a big loss—thanks!
Inclusion rate improved after moving to private bundles.
Hope to see more examples on Polygon.
Adding a “pitfalls” section was a nice touch.
Great primer on private bundles and risks.
Would love a follow-up on simulation best practices.
Please cover bundle failure modes and retries.
Benchmarks vs public PGA would be amazing.
The checklist was super helpful—please add a section on reorgs.
Would love a video walkthrough for setup.
Latency figures would be nice to benchmark against.
