 ### Environment Variables
 
-The project comes with a `.env.example` file. You should rename it to `.env` and fill the variables with your values. Most RPC providers offer free testnet nodes. You can use [Alchemy](https://www.alchemy.com/) or [Infura](https://infura.io/) to get a free node.

You can use [Alchemy](https://www.alchemy.com/) or [Infura](https://infura.io/) to get a free node. We are currently using Sepolia for testing purposes but you can use any other provider and evm chains to test the application.
+
+Alchemy has two types of keys, one for the HTTP provider and another for the Alchemy SDK. You should use the HTTP key for the `NEXT_PUBLIC_ALCHEMY_SEPOLIA_HTTP` variable and the SDK key for the `NEXT_PUBLIC_ALCHEMY_SEPOLIA_KEY` variable.
+
+The HTTP key is used to connect to the blockchain and the SDK key is used to connect to the Alchemy API, which allows us to get the user custody tokens easily.
