are the wallets generated from the elrond wallet? any idea where i could find these details?

The wallet seeds from webwallet are able to restore maias, defi wallet, ledger, metamask, trustwallet etc, so if you happen to send Erc20 or bep20 to your Maiar eth address you would be able to recover them, in the future I image more options in Maiar will be available in terms of token choice

Actually kinda beyond me ?. Maybe @margaritapaws can answer that.
