the only way lite accounts works fine is use a EVM chain as proxy. Not for transactions. But for log in into hive.
So a "mother wallet with multi sig" can make transactions for those EVM chain lite wallets.
Unlimited wallets but no connection was needed to the chain. Only verify via metamask.
Easy.
A Custom Json could look like that: Wallet-adress/transaction(buy splinterlandscard xyz).
So everyone knows EVM wallet xyz owns Splinterlands card XYZ on hive.
Something I started working on it, but because of technical problems ( no skills in deep programming), I stop.
Was for a front end idea i had for mass onboarding. I mean i would need cheap wallets for onboarding, otherwise, marketing would become to expensive for my idea :)
