Hardhat with TypeChain integration https://github.com/ethereum-ts/TypeChain/tree/master/packages/hardhat

Develop

Step 1: Deploy smart contract on local node

Open 1st terminal, then run below command

npx hardhat node
# or
bun run local-node

For example, below is my result.

npx hardhat node
Started HTTP and WebSocket JSON-RPC server at http://127.0.0.1:8545/

Accounts
========
Account #0: 0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266 (10000 ETH)
Private Key: 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

Next, compile and deploy to local node

# Compile smart contract and generate types for typescript
npx hardhat compile
# Deploy localhost
npx hardhat run scripts/deploy.js --network localhost
# Or
bun run compile-node

You will get the deploy address from CLI. For example:

npx hardhat run scripts/deploy.js --network localhost
Generating typings for: 0 artifacts in dir: src/types for target: ethers-v5

Successfully generated 3 typings for external artifacts!
Greeter deployed to: 0x9fE46736679d2D9a65F0992F2272dE9f3c7fa6e0
Token deployed to: 0xCf7Ed3AccA5a467e9e704C703E8D87F634fB0Fc9

Step 2: Run react app

Create .env from .env.example from root directory. Remember to fill the value for deployed addresses.

# .env
VITE_GREETER_ADDRESS=
VITE_TOKEN_ADDRESS=

# Fill below information if you want to deploy to Mainnet/Testnet
ROPSTEN_PROVIDER_URL=
RINKEBY_PROVIDER_URL=
MNEMONIC=

# Verify smart contract on EtherScan
ETHERSCAN_API=

Then run below command

bun run dev

Deploy to Ropsten Testnet

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

Verify contract

npx hardhat verify --network ropsten VITE_GREETER_ADDRESS 'Hello, Hardhat!'

You might have something similar

npx hardhat verify --network ropsten 0x0608Cc0b2970729f4577Eae89403cAE3049C1525  'Hello, Hardhat!'
