You need run 3 app, using 3 terminals:

1. Frontend
2. Blockchain local (anvil)
3. Deploy your smartcontracts into blockchain

1. Install frontend

cd ui
npm install # or yarn or pnpm install

2. Run application

npm run dev # or yarn dev or pnpm dev

anvil -b 1 # Mining blocks every 1 second

cd smartcontracts
./deploy-on-local.sh

Explain:

• The contracts folder contains everything you need to build smartcontracts.
• The ui folder contains everything you need to interact with your smartcontract using frontend.

• deploy-on-local.sh: just call it to deploy, it makes deployment simple without copying and pasting things.
• src/*: the folder where we will write our contracts.
• test/*: the folder where we will write our tests.
• lib/*: the folder where the foundry stores the libraries.
• script/deploy.local.s.sol: the solidity script responsible for actually doing the deployment.
• test/BaseSetup.t.sol: is the contract where we are going to configure the tests.

• contracts/deployedContracts.ts: ABI of the contract that will be ‘auto-magically’ copied by the smartcontracts/deploy.py script.
• package.json: list of dependencies and commands to run the frontend.
