There are many dApps supporting Binance Chain wallet:
dApps need to ask permission to view users’ accounts. Users could see “Login” or “Connect” buttons on Binance Smart Chain dApps. These buttons will prompt a popup from Binance Extension wallet asking if the user wants to grant the site access to their public account information. For example:
https://www.binance.org/en is the official website for Binance Smart Chain. This is a default and cannot be removed.
Binance extension will remember which sites have been approved until the user wish to change their list. Once you wish to edit the connected sites list: You need to:
Select the account you’d like to change
On the Account page, click on the menu (three dots) and lick “Manage Connected Sites”
If you wish to replace MetaMask with Binance Chain extension wallet when trading on dApps, just go to "Settings" >> "Conflicts". Then, enable the option of "Avoid conflict with MetaMask". In this way, BEW will pop up instead of MetaMask
