< How to use Token Bridge (ERC-20 🡪 BEP-20) >

Currently, the Microtuber Coin supports two networks, the ERC-20 and the BEP-20 network. Microtuber’s cross chain bridge allows you to convert your Microtuber Coins from one network to the other.
In order to use bridge, you need a Metamask wallet.

★ Using bridge and transferring coins incurs a gas fee (transaction fee).This gas fee is paid in Ethereum when the ERC-20 Network is used, and in BNB tokens when the BEP-20 is used.
