# Liquidity Lockers V4

To understand what liquidity lockers are, first you have to be familiar with concepts of liquidity pools.

If you are not, we recommend watching [this video](https://youtu.be/cizLhxSKrAc).

## What is a liquidity locker?

Developers listing their tokens on Uniswap V4 are granted an NFT when they initiate a pool. This NFT representing the LP position, once in their possession, can be transferred like any other tokens on the blockchain they have been minted on, or bridged to another one.

A liquidity locker allows the developer to store the NFT in a smart contract, revoking their permission to move the NFT from a start date to an end date. <br>
