Create a MetaMask Wallet or Import One
I’d suggest creating a new one if you haven’t done so.
Click import wallet if you have an existing wallet.
Set up your password and secret recovery phrase somewhere safe.
Setup MetaMask to connect to BSC Mainnet
Switch the connected blockchain by clicking on the tab saying Main Ethereum Network, we need to add the Binance Smart Chain network.
Scroll down until you find Custom RPC.
Enter in the BSC mainnet details as follows:
Network Name: BSC Mainnet
New RPC URL: https://bsc-dataseed1.binance.org/ or https://bsc-dataseed2.binance.org/
ChainID: 56, or 0x38 if 56 doesn’t work
Block Explorer URL: https://bscscan.com/
You have now connected to the BSC mainnet with your Metamask Wallet.
