Swap Fee

A swap fee is a small percentage charged on every trade executed through a decentralized exchange or liquidity pool. These fees are collected and distributed to the liquidity providers as compensation for their service and the risks they undertake, such as impermanent loss.

The fee structure is a key component of the protocol's incentive model. It must be high enough to attract liquidity but low enough to remain competitive for traders.

Some protocols use dynamic fee structures that adjust based on market volatility or trading volume. These fees represent the primary revenue stream for many liquidity providers.

They are an essential part of the ecosystem's economic sustainability. Without these fees, there would be no incentive for users to provide the necessary liquidity.
