Metamask is a decentralized wallet. It can be installed on your Web Browser (e.g. Chrome), IOS or Android mobile phone. If you would like to download Metamask, kindly go to the Download Page.
For the following demo, we are using the Metamask IOS app. Don’t worry, the steps for all platforms are similar.
After you create or log in your account, you may check the Network on the top. It shows which blockchain network you are on. Click and it will show all the networks you have.
As we can see, there is no BSC network. In this case, we need to add BSC to your Metamask：
1. Go to Settings;
2. Find Networks;
3. Click [Add Networks] and filling in the following information:
Network Name: Binance Smart Chain
New RPC URL: https://bsc-dataseed.binance.org/
Block Explorer URL: https://bscscan.com
4. After you add the BSC network, you will be able to shift from ERC20 to BSC.
