Deploy Uniswap

Overview

Uniswap is a decentralized exchange (DEX) protocol built on the Ethereum blockchain. Uniswap allows users to trade Ethereum-based tokens without the need for an intermediary or a centralized exchange. It uses a unique automated market maker (AMM) system to facilitate trades and provide liquidity to the platform.

Uniswap operates on a set of smart contracts that are open-source and decentralized, meaning they are not controlled by any centralized authority or entity. Instead, users interact directly with the smart contracts using their Ethereum wallets, and participate in the platform's liquidity provision and trading features.

A key feature of Uniswap is its unique AMM system, which uses a constant product formula to determine the price of tokens on the platform. This means that the price of a token is determined by the ratio of the token's supply to the supply of another token in a trading pair. This system allows users to trade tokens without relying on order books or centralized matching engines.

Another important feature of Uniswap is its liquidity provision system, which allows users to provide liquidity to the platform in exchange for a share of trading fees. This allows users to earn a passive income by contributing to the platform's liquidity and helping to facilitate trades between different tokens.

Uniswap has become one of the most popular decentralized exchanges on the Ethereum network, with a wide range of tokens and trading pairs available for users to trade. Its decentralized and open-source nature makes Uniswap a popular choice among cryptocurrency enthusiasts who value the principles of decentralization, transparency, and community governance.

Add Waterfall Network to hardhat.config.js file

networks: {
  ...
  waterfall: {
    url: "https://rpc.testnet8.waterfall.network",
    chainId: 8601152,
    accounts: ['07201008f00b31de405a0af22ff04871044e027878929b7b47569ca76555ff09'], // Private key from your account

  }
}

Create scripts directory
```
mkdir scripts
```

Create deploy.js file in scripts directory and past next code:

async function main() {
  const UniswapV3Factory = await ethers.getContractFactory('UniswapV3Factory')

  // Start deployment, returning a promise that resolves to a contract object
  const uniswapV3Factory = await UniswapV3Factory.deploy()
  console.log('Contract deployed to address:', uniswapV3Factory.address);//0x61F5cC6C2792d7409FEC7ED4E798135e8fc26fD2
