# BestMeme V3 **BestMeme V3** **2025.01** Uniswap V4, set to launch in January 2025, introduces a groundbreaking new feature: the hook function. This allows for direct interaction with external smart contracts, enabling a wide range of customizable functionalities within the protocol. **Solution:** The PoolManager will call the hook,then the hook will call the minting function and push the minted tokens to liquidity in the beforeSwap hook. **Step 1: Meme Coin Creation** Users spend 50 USDT to purchase 0.01% of the total supply, equivalent to 100,000 tokens. At the same time, users need to set an Auction Duration, ranging from 1 hour to 100,000 hours. **Step 2: Adding Initial Liquidity** The smart contract mints an additional 100,000 Meme Tokens(0.01%) and pairs them with 50 USDT to create an initial liquidity pool on Uniswap V4. **Step 3: Trade on Uniswap V4 and Dutch Auction** After creation,users can buy and sell on Uniswap V4 immediately. Whenever a user initiates a trade, the PoolManager will invoke the auction smart contract via the beforeSwap hook. This triggers the distribution of tokens into the liquidity pool until 99.98% of the total token supply has been minted. **Step 4:Trading fee Allocation** A 1% fee applies to all trades. Half of this fee supports the creator, while the remaining 50% funds the protocol. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
