    Solidity Code Snippets

    The Uniswap V2 Core contracts provide functionality for interacting with Uniswap smart contracts. This contract interface has an Approval and Transfer event function that allow for sending and receiving Uniswap V2 ERC20 tokens. Additionally, the contract has a name(), symbol(), decimals(), and totalSupply() functions to store data.
