💵Web3 Wallets

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.
