# Fee types

We charge gas fees and fixed fees. 

### [Gas fees](/layerakira-documentation/integration/trading/fees.md)

The gas fee covers the cost for deploying actions on-chain. Some actions on the Exchange will require the user to specify the maximum they are willing to spend on Gas. 

The semantics of the gas fee work the same way as transaction fees:

* The gas fee is an absolute value and represents the cost required to perform the transaction. 
* The gas fee covers on-chain actions that our Exchange performs on behalf of the user
* This amount may also be paid in whitelisted cryptocurrencies such as USDC / USDT via paymaster

On the LayerAkira spot DEX, the token the user pays gas with will depend on if the user specifies the "spend" or "receive" field:

* If an amount is specified in the **spend field**, gas is paid in the **receive currency**.
* If an amount is specified in the **receive field**, gas is paid in the **spend currency**.

This flexible system ensures gas fees are intuitive and align with the user’s chosen transaction parameters.

### [Fixed fees](/layerakira-documentation/integration/trading/fees.md)

This will be calculated as a percentage relative to the order size.

When orders remove liquidity from the order book, they will incur a **taker fee** of 10bps**.**
