# Refuel ## **How Refuel Works on BIM Exchange** Refuel would be integrated directly into the BIM Exchange bridging flow as an optional feature. Users would simply activate the **Refuel** option in the interface before confirming their swap or bridge. The goal is to make sure that, once the transaction is completed, the user arrives on the destination chain with enough gas to continue using BIM Exchange or other DeFi applications immediately. #### **How Refuel Works** Refuel operates in two possible modes: **Manual Mode**\ A small amount of native token from the source chain is sent alongside the bridged asset and delivered as native gas on the destination chain, even if the native tokens are different across the two chains. **Auto Mode**\ No additional native token is required from the user on the source chain. Instead, a small portion of the input amount is automatically allocated to provide native gas on the destination chain. #### **Fees** Refuel does **not charge any additional protocol fee**. The only deducted amount corresponds to the gas costs incurred on the destination chain in order to provide the user with native gas. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
