Dice rolling only begins to start making sense when you:
(1) Verify entropy → seedphrase on an independent device, to check the device actually used it.
(2) Verify seedphrase → root private key → public key conversions on an independent device.
(3) Roll dice to generate nonces every time you want to spend bitcoin, since nonces are another random number that the device could create poorly or maliciously...
.. Or because no one realistically does this, verify that the device correctly signed using deterministic nonces (no one does this either). Both methods requiring verification on an independent device if you don't want to trust.
You'll notice that there's a pattern of:
- Don't trust a single device to generate randomness
- Verify on another device
And that's exactly what FROST's Distributed Key Generation and signing achieve; but it's automated and not completely insane.
Each device participating in key generation contributes a random secret a group secret key. So long as one of them has good entropy, so does the the entire multisignature.
Crucially, the devices do not trust that their entropy was utilized, they mathematically verify that their entropy was included in the wallet secret. And furthermore, every participating device agrees upon the public keys and addresses by default at the end of the protocol.
Distributed Key Generation validates everything, all you need to do is confirm that a short security check code matches on all device screens, which verifies that every device saw the same sequence of events within this ceremony. Frosty.

The phone has a different entropy source with different inputs. The devices each have a multitude of unique entropy inputs too!

The only hardware wallet never trusted to generate its own entropy. https://blossom.primal.net/3e01e1f6cc9b7c4f995bbd5d2bdcde05df246832de93335b7dbd4e6b68110d0a.png

Gold bars have to exist somewhere. Bitcoin does not.

We're getting this one reviewed and through!
https://github.com/frostsnap/frostsnap/pull/511
In the meantime you can use another device as a coordinator if you have one available.
We ourselves really want subaccounts! So expect to see progress on them soon.

No: your choice of electrum server will determine the chain your wallet syncs to. The defaults are non-BIP110 servers. In any case it is best to connect the app to your own node.

The full private key never exists. Not at creation, not at signing, not ever.
In case you missed it, Sovereign Money gave the most thorough breakdown of Frostsnap yet:

Three years ago we attended @nprofile…py4c, jumping booth-to-booth to share our early prototype with friendly faces we'd only ever interacted with online.

This year we're back with the real thing: Frostsnap. Multisig made simple, with no single point of failure.

Should be fixed now, you might need to open in different browser / with clear cache.

You can export your wallet descriptor into other wallets such as Sparrow Wallet, build transactions as PSBTs, and sign them on your Frostsnap devices
