Setting .env

The .env file is a configuration file.

In the hedera-nft-scripts folder, rename .env.example for .env

Open .env with your favorite code editor.

Fill the required fields inside the .env file and save it.

Not all values are required for each script, that's why inside the .env file itself you will find sections to highlight the use.

We encourage to reset the .env after use of our scripts. Especially private keys/keys values to not leave any sensitive value on your computer. Be sure to have these infos saved safely somewhere though.
