# Wallet Extension

Note:

1. It's not possible to make transfers if your wallet only contains ARC-20 and lacks BTC or if your BTC balance is insufficient to cover gas fees. When your BTC balance is insufficient, you will receive a wallet prompt indicating 'Insufficient Balance.' 
2. To ensure the safety of your assets during transfers, the wallet has identified Ordinals and Atomicals assets to prevent them from being mistaken for gas consumption. \
   Therefore, **no need to worry about accidentally sending ARC-20 as a transaction fee** when using the Atomicals wallet.

Atom Wallet extension has been listed on the Chrome Web Store. There is two ways to install Atom Wallet extension: 

1. Chrome Web Store: <https://chromewebstore.google.com/detail/wizz-walletformerly-atom/ghlmndacnhlaekppcllcpcjjjomjkjpg>
