That's actually a good point when it comes to hotwallets too that come in the form of apps, extensions, you name it:

Recommended desktop wallets: BitPay, Exodus, Electrum.
Recommended web wallets: Coinbase, Metamask, Guarda.
Recommended mobile wallets: BitPay, Edge, Trust, Electrum, Blockchain.com.



Also, the question "why cram so much into the phone", has been asked so many times for the last 20 years. Humanity doesn't seem to care, and seems to constantly deviate towards innovation when it comes to smartphones.

I've read into the Saga phone the other post mentioned, and it does seem to service the market of people who want all four of security reliability convenience and mobility when it comes to hotwallets.

They have this thing called a "seed vault" https://github.com/solana-mobile/seed-vault-sdk
It's part of an open source software collection called the SMS or Solana Mobile Stack.

Anyone here that's good at reading code have any input on if something like this is good or not?
