Binance smart chain metamask: Here is a detailed course on binance smartchain on metamask. this contains all you need to know on this topic:
Installing and configuring MetaMask
MetaMask can be downloaded on Chrome and Firefox, or iOS and Android if you’re a mobile user. For the purposes of this tutorial, we’ll be using the Firefox version, but the instructions will be more or less the same for each platform.

First, you’ll want to head to the MetaMask download page. From there, select the platform you are using and follow the steps to install it on your device. Easy!
Then follow the configuration indicated by the application. Go ahead and click Create Wallet. Write down the backup seed phrase in a secret location (preferably not on an internet-connected device). Without this phrase, your funds cannot be recovered if your device is damaged or lost. Confirm that you have noted them on the next page.
And that’s all! You should now see your wallet, ready to send and receive funds.
