GreenBTC requires users to have a Web3 wallet.
It is used to display a user's Digital Collections and Crypto Assets.
The wallet is a simple interface to connect a user to a blockchain via a secret passphrase which is known as a "seed phrase" (this is 12 randomly generated simple English words).
Against typical perceptions, nothing is ever stored on a wallet. The seed phrase is simply a key to tell a blockchain which assets the user has access to.
This means that you can take any seed phrase and import it into any wallet to view a user's assets. It's also why it's so important to guard it with the utmost security as most people who are hacked or scammed in Web3, have their seed phrase compromised at some level.
This is the industry standard Web3 wallet and available for both Browser Extension and also Mobile.
