custodial = account. It's not a wallet at all in my mind. (I suppose you can argue it's a wallet because the custodian can send transactions on your behalf, but I still don't think we should call custodial accounts wallets).

if Sorted Wallet uses Breeze SDK, that means users have keys to their bitcoin. the altcoin parts of the wallet expand the attack surface, but if I have to choose between the two, I'd prefer to have my keys, even in a wallet with extra shit.

As an interesting note, the Sorted wallet website hasn't updated their FAQs yet to reflect the integration of the Breeze SDK: > Sorted Wallet currently supports 3 blockchain networks; Ethereum Main Network, Polygon Mainnet and Tron Mainnet. source
