uniswap

Project to discover and master Uniswap V2 and V3

Installation:

First install uniswap dependencies

yarn add @uniswap/v2-core @uniswap/v2-periphery
yarn add @uniswap/v3-periphery @uniswap/v3-core

For our tests we fork the ETH mainnet, add the following lines in hardhat.config.ts

networks: {
    hardhat: {
      forking: {
        url: ALCHEMY_MAINNET,
      }
    }
}

To test if it works and get the latest block:

curl --location --request POST 'localhost:8545/' --header 'Content-Type: application/json' --data-raw '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

Now the fork is active when you launch a node and test

npx hardhat node
npx hardhat test
