Several networks of the blockchain are usable from your metamask. Let's take care of two important ones, ERC-20 and BEP-20.
ERC-20 corresponds to the main ethereum network.
The BEP-20 mainnet corresponds to the Binance Smart Chain network.
These two networks can be used via your browser thanks to methamask.
For those who wish to set up access to the BSC Mainnet network, I invite you to read this article.

These two networks do not work on the same protocol, you cannot send your ERC-20 tokens to the BEP-20 network.
A new solution :
Binance has just solved this issue and launched a bridge between the different networks.

Start by connecting your metamask wallet and select the network from which you wish to migrate your tokens.
Then select the asset you wish to transfer, the network from which tokens are to be migrated and the network to which they are to be migrated.
You just have to enter the amount and validate the transaction.
Your tokens have now been migrated from one network to another.
Note: you can transfer from many networks such as polkadot, atom, eos and many others.
