Custom web UI for the forked Uniswap V2 smart contract

This project uses create-react-app, ethers.js, and hardhat.

This project uses forked Uniswap V2 repos for the core and periphery.

All local development was done using VSCode Docker-Remote plugin to ensure consistent development setup. See .devcontainer directory for the configuration of the containerised local development environment.

It should be possible to build this project on any machine that can run node.js and npm, but it's not guaranteed.

The following assumes the use of node@>=10.

This project has dependencies that are hosted in GitHub npm registry. In order to install all dependencies you need to create a personal access token (PAT) and use it to log into the GitHub registry:

$ npm login --scope=@lobanov --registry=https://npm.pkg.github.com

> Username: GITHUB USERNAME
> Password: GITHUB TOKEN
> Email: PUBLIC-EMAIL-ADDRESS

npm install

Harthat network is used for local development and testing. Start it with the following command.

npx hardhat node

This is required when working locally as Hardhat network will be empty. The following command will deploy uniswap core and periphery contracts, WETH contract, and a TEST ERC-20 token.

npx hardhat run --network localhost scripts/local-bootstrap.js

This command will write contract details into .env.development.local file, which will be picked up by the webapp.

npm start

Configure MetaMask to connect to the network at http://localhost:8545.

Note there are 20 test accounts with privates keys printed in the log when Harthat network starts. You will need to Account #0 to MetaMask or other compatible wallet. This account is the owner of the Uniswap factory, the WETH-TEST liquidity pool, and a balance of TEST tokens.

You will need PROJECT_ID and PROJECT_SECRET values.

INFURA_PROJECT_ID=<<PROJECT_ID>>
INFURA_PROJECT_SECRET=<<PROJECT_SECRET>
ROPSTEN_DEPLOYMENT_ACCOUNT_PRIVATE_KEY=<<PRIVATE KEY OF THE DEPLOYMENT ACCOUNT>>
WETH9_CONTRACT_ADDRESS=0xc778417E063141139Fce010982780140Aa0cD5Ab

npx hardhat run --network ropsten ./scripts/deploy-contract.js

Don't forget to change .env.production to point at the newly deployed contracts.
