# Swap

## Overview

The `UniswapSwapAndLiquidity` contract is designed to interact with the Uniswap V2 decentralized exchange platform. 

It facilitates two primary DeFi activities: swapping tokens and adding liquidity to Uniswap pools. 

By integrating with the Uniswap V2 Router, this contract provides users with the ability to engage in token swaps and liquidity provision directly through the contract, simplifying and streamlining these processes.
