You can add funds like ETH to your Element wallet by:
- Log in at app.elementunited.com
- Select Wallet from the left-hand navigation menu
- Click the Receive tab
- The QR code displayed contains your wallet address, or you can copy and paste the alphanumeric text.
This is your wallet address and will be what is entered into the "TO" field when sending funds from your external wallet such as a Coinbase or MetaMask wallet.
