Development

Install dependencies

npm i

Set up environment variables

Copy the .env.local.example file in this directory to .env.local (which will be ignored by Git): Then, open .env.local and add the missing environment variables:

• REACT_APP_INFURA_PROJECT_ID - Infura project id (get it from infura.io).
• REACT_APP_CHAINNODE_PROJECT_ID - Chainnodes project id (get it from chainnodes.org).
• REACT_APP_ANKR_PROJECT_ID - Ankr project id (get it from ankr.com).
• REACT_APP_IPFS_DEPLOYMENT - Is dApp in the mode for deployment on IPFS. Set to false.
• REACT_APP_BUNGEE_API_KEY - Bungee API key.
• REACT_APP_WALLET_CONNECT_PROJECT_ID - WalletConnect project id (get it from WalletConnect Cloud).

Set up Google Translate API

This step is needed only if you wish to contribute to the project.

On every commit a pre-commit hook is triggered to translate missing values from the en.json located in src/i18n.

In order for this to work a Google Cloud account is needed and a system environment variable needs to be set pointing to a locally stored json provided by Google.

The translation script is located in check_translations.js.example. Create a new file called check_translations.js identical to check_translations.js.example and set the projectId variable to the project id provided by Google.
