Environment

Now that our installation is complete, let's configure the development environment for ETH Mobile.

1. Connect your device to your computer via WIFI-HOTSPOT​

2. Initialize a Local Blockchain:​

In the first terminal, run a local network from the project root folder:

yarn chain

This command starts a local Ethereum network hosted on your local IP address. The network runs on your local machine and can be used for testing and development. You can customize the network configuration in hardhat.config.ts.

Alternatively, you can use Ganache to persist the blockchain state during development

3. Deploy Your Smart Contract:​

In the second terminal, deploy the test contract:

yarn deploy

This command deploys a test smart contract to the local network. The contract is located in packages/hardhat/contracts and can be modified to suit your needs. The yarn deploy command uses the deploy script located in packages/hardhat/deploy to deploy the contract to the network. You can also customize the deploy script.

4. Configure the local provider:​

Set the ALCHEMY_KEY and localhost.provider(port 8545) variables in packages/reactnative/ethmobile.config.ts

To determine your local IP address:​

Mac:​

ipconfig getifaddr en0

Windows:​

ipconfig

5. Connect your device via USB or Run an emulator​

6. Launch your React Native Application:​

Android:​

yarn android

IOS:​

yarn ios

7. Import an account from your local blockchain into your wallet to have funds for testing​

What's Next:​

  • Interact with your smart contract in the DebugContracts tab.
  • Configure your supported networks in packages/reactnative/ethmobile.config.ts.
  • Run smart contract test with yarn hardhat:test
  • Edit your smart contract YourContract.sol in packages/hardhat/contracts
  • Edit your frontend in packages/reactnative/src/screens
  • Edit your deployment scripts in packages/hardhat/deploy
