I see, so ICP can't store in wallets like trustwallet, metamask or safepal? so currently there are only a few wallets that support such as "Fido U2F" does it only support hardware wallets?
As I understand it
https://nns.ic0.app/ is the only official app and you need a dedicated security key to transact with it.
the Fido U2F acts a key using the ledger
