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.
These issues are usually addressed in more detail in the whitepaper or yellow paper. I seem to remember someone from the team posting somewhere in this thread some technical version of the document - I don't know why they didn't additionally put it on the first page along with other important info though...
They should as everyone that comes first to the project looks at that first page for the essential info. Everything should be present there.
