# Fee Management Contracts

The **ClankerFeeLocker** and **IClankerLpLocker** contracts are used to manage the fees generated from the tokens. The **IClankerLpLocker** is on its second implementation, **ClankerLpLockerFeeConversion,** which is used to manage the LP fees for a token's deployment liquidity.
