HIVE-Engine is very difficult to use for a Solana user joining in for the first time. It is easy for a HIVE users to send trade wrapped Solana assets on HIVE-Engine; but not the other way around. Keystore on LeoDEX will not have the same problems. I'm not informed enough about the implementation details of VSC + Solana. I know that there are some form of Lite Accounts in the works.
