3. Ensure at least one AVD image is available for the emulator (unless using a physical device).

Developing

If you are new to React Native, this is a helpful introduction: https://reactnative.dev/docs/getting-started

Preflight

1. Run nvm use to force Node.js v16.

2. Set up your .env file, use our env.example as a guide.

   Note that some features are currently not accessible, we are working with our Data Providers in order to provide open source API Keys!

   Here are some resources to generate your own API keys:

   • Etherscan: https://etherscan.io/apis
   • Infura: https://infura.io/
   • ETH Gas Station: https://docs.ethgasstation.info/
   • Imgix: https://www.imgix.com/

3. Ensure a google-services.json has been added to the relevant project directory/directories so the compile will not fail.

   This can either be the live Google Services config (for internal development) or a self-provided config for a personal Firebase project (third-party contributors) registered under the package name me.rainbow.

MacOS
