Branch Info

Author: Austin Griffith Source code: https://github.com/scaffold-eth/scaffold-eth-examples/tree/uniswapper Intended audience: Intermediate Topics: Scaffold-eth basics, DEX

🏃‍♀️ Quick Start

git clone -b uniswapper https://github.com/scaffold-eth/scaffold-eth-examples.git uniswapper-scaffold
cd uniswapper-scaffold
yarn install
yarn start
  • In a second terminal window run:
yarn fork
This branch uses a local fork of mainnet, which is easy to do with Hardhat (see here to learn more). The template configuration uses an Infura node, however this is not a full archive node, so it will only work for an hour or so. To get a long-lasting fork...
  • Go to alchemyapi.io and get an API key for mainnet
  • Replace the Infura URL with an Alchemy URL with your API key (i.e. https://eth-mainnet.alchemyapi.io/v2/<API_KEY_HERE>) into the fork script on line 28 of /packages/hardhat/package.json
📱 Open http://localhost:3000 to see the app
  • This widget uses tokenlists to import the erc20s of your choice
