GoPlus SafeToken Locker for Uni V4

What is a Liquidity Locker?

In Uniswap V4, when developers create a liquidity pool, they receive an NFT representing their LP position. This NFT can be transferred like any other token on the blockchain or bridged to another chain.

The liquidity locker service allows developers to store their NFT in a smart contract, revoking their permission to move the NFT from a start date to an end date. This provides additional security and transparency for projects, demonstrating to investors that the project's liquidity is locked.
