You right. AT first, we will use erc-20 tokens and in Q1 then mainnet will be checked and start we will exchange erc-20 tokens 1:1.
An interesting solution. I think hurrying with it is not worth it, if the ETH network will work normally, then why not continue to use it.
Any financial platform should be as safe as possible. By using its own blockchain number of potential vulnerabilities will be reduced.
