In order for you to see the ATTR balance in your crypto wallet, you need to add the contract address.
ATTR ERC20 Contract address: 0x44e2deC86B9F0e0266E9AA66e10323A2bd69CF9A
Testnet (Rinkeby): 0x926362b451A012F72b34240F36C3bDc163d462e0

1. Open the extension, scroll down and hit the ‘Add Token’ button
2. Select the ‘Custom Token’ tab, and paste in the ATTR contract address
