# Fees The Joint Protocol collects a fee when a swap is completed. 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. --- # 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.
