# Fee Management Contracts

The fee management contracts collect, split and hold the fees generated by Clanker v4 tokens until recipients claim them.

* [**ClankerFeeLocker**](/documentation/references/core-contracts/v4/fee-management-contracts/clankerfeelocker.md): The user-facing contract where recipients view and claim their accumulated fees.
* **IClankerLpLocker**: The interface for lockers that manage the LP fees for a token's deployment liquidity. It is on its second implementation, [**ClankerLpLockerFeeConversion**](/documentation/references/core-contracts/v4/fee-management-contracts/clankerlplockerfeeconversion.md), which replaced [**ClankerLpLockerMultiple**](/documentation/references/core-contracts/v4/fee-management-contracts/clankerlplockermultiple-deprecated.md).
