This is mobile wallet app. I needed blockchain for further developments with tokenization/micropayments as I have worked with this for a long time already.
I could use straightly for example a token created with Solana or XNO for micropayments but then my platforms are based to other blockchains.
With own blockchain the success rate is bigger than using for example Solana token.
I can not not use Solana/eth/btc or tokens with fees with user authenticator as the way I want. There are many reasons why own blockchain is smarter.
