# 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 :rocket:

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 :scales:

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<br>

***

### 3. Max Profit Mode :money\_mouth:

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
