Brave Wallet

Brave Wallet was created as part of the Brave browser in order to bring cryptocurrency and web 3 access to Brave's users.

Users can access the Brave Wallet by navigating to brave://wallet or from the wallet icon at the top of the browser.

Ethereum provider global object

The window.ethereum object is provided by Brave's wallet to web pages. You can read about it here: https://github.com/brave/brave-browser/wiki/Ethereum-Provider-API

Brave Wallet settings can be accessed from: brave://settings/wallet

The default wallet setting can be set to one of the following values:

Brave Wallet (Prefer extensions): This is the default setting. With this setting, window.ethereum is exposed by Brave Wallet; however, extensions such as MetaMask are still allowed to overwrite window.ethereum.
Brave Wallet: With this setting window.ethereum is exposed by Brave Wallet and extensions do not have access to overwrite window.ethereum.
Crypto Wallets (Deprecated): This setting only shows up for existing users that have used Crypto Wallets in the past. Crypto Wallets was Brave's old cryptocurrency wallet and it was a MetaMask fork. If this setting is selected, navigating to brave://wallet will load Crypto Wallets instead of Brave Wallet. New users can access this setting only if they have brave://flags/#ethereum_remote-client_new-installs set to true manually.
None: With this setting users can still navigate to brave://wallet, however no window.ethereum object is exposed.
