# Fees

The Joint Protocol collects a fee when a swap is completed.&#x20;

Two types of fees exist in the protocol -- *market* and *protocol* fees.

### Market Fee

When a market creator creates a market, they can set a commission that will be deducted from every swap originating from their market. However, the market fee is optional; the creator can remove it.

### Protocol Fee

The protocol fee is a compulsory fee charged on all swaps across all markets.&#x20;
