Binance Smart Chain Wallet
With the Binance Smart Chain wallet, you can send and receive funds on Binance Chain, Binance Smart Chain and Ethereum, and cross-chain transfers between both of Binance’s blockchains.
The app can also integrate with other Binance Chain products for authentication and transaction signing without providing access to your private keys, which are stored securely within the extension’s storage space and encrypted with your password.
To make this integration possible, the app needs to add code to handle the communication between web apps you open in your tabs and the extension itself. This is why the app requires the permission to access any webpage.
