Encryption cases for Binance Chain, Binance Sensitive Chain, and Ethereum use the Binance Chain browser extension. You can send and receive funds on Binance Chain, Binance Sensitive Chain, and Ethereum, as well as cross-chain transfers between Binance blockchains. Binance Chain products are used for identity verification and sign language transactions without authorization to access your non-public keys. These non-public keys are permanently stored together with your password between the storage and the encrypted extension room. In order to achieve this integration, the extension needs to add code to handle the interaction between the Web applications it opens in its tabs, and thus interact with the extension itself. This may be why the extension needs permission to access any page on the Internet.
