# Swapping Explained

The swap feature is used when traders want to exchange tokens within trading pairs. 

On Camelot, users are charged a [trading fee](/tokenomics/protocol-earnings.md) when they make a token swap.\
[Liquidity](/get-started/castle-tutorials/providing-liquidity-explained.md) is provided to the exchange by liquidity providers, who add their tokens to liquidity pools.

### Swap modes

* V3 - This mode exclusively uses the V3 AMM
