Gas Kickback Modes on ETH
Kolibrio supports multiple kickback modes for Ethereum transactions. Each mode changes how your priority fee is handled between transaction inclusion and gas rebates.

1. Solver Mode 🚀
This mode guarantees the best in-block position for your transactions.
100% of the priority fee is used to maximize in-block placement.
Ideal for traders, sniper bots, market makers, searchers, solvers who care about being placed as high as possible inside the block.
You may still receive a priority gas kickback as a bonus, but it is not the main goal.
Properties:
Highest in-block position
Not guaranteed to generate high priority gas kickback
2. Balanced Mode ⚖️
The default mode recommended for most users.
Ensures next block inclusion with high reliability.
A fixed portion of the priority fee is saved and distributed back as priority gas kickback.
Best choice for wallets and dApps that need resilient inclusion without extreme fee spending.
Properties:
Next block inclusion
Balanced priority gas kickback
3. Max Profit Mode 🤑
This mode maximizes revenue sharing for the orderflow provider.
The majority of the priority fee is saved and returned as priority gas kickback.
Best for non–time-sensitive transactions where monetization is more important than instant inclusion.
Expect slightly slower confirmation compared to Solver mode.
Properties:
Next or +1 block inclusion
Highest priority gas kickback
