I've read that your platform will be integrated with MetaWallet, isnt it called Metamask instead of MetaWallet?
Metawallet means that they will support many kinds of tokens.
So it wont support only erc20,right?
It says it will. And it makes sense because ERC-20 is the most used by projects. Neglecting that could cause problems in the future. And ERC20 can be stored on hardware wallets and more and more people are using those for security reasons.
Its a general standard, but it still supports all kinds of tokens.
