It is though, and definitely better than using a HWW that has so much supply chain risk like your trezor.
SeedSigner uses generic non BTC related parts.

A sandboxed phone w graphene is more secure than pretty much any Linux setup a normal person will execute.
What supply chain risk? The Trezor has tamper evident packaging.
Say that again to yourself AFTER you build a seedsigner
Ancap - the graphene device substitutes your computer. The internet connected device must always also be secure. Not just the HWW.
The trezor is subject to supply chain attack. No matter what bag it comes in. All the centralized HWW's are. So, do multi vendor on your multi-sig.
I’m sorry dude but the idea that a smartphone is more secure than an airgapped hardware wallet like a Passport is the most retarded thing I’ve ever heard a bitcoiner say.
These wallets have checks that prove they were not tampered with. How do you think a supply chain attack is more likely than a security vulnerability in GrapheneOS
Dude you're being a fucking regard
The phone is in place of your computer, not a hardware wallet.
You use the hardware wallet, airgapped preferably, with an internet connected device.
That's either a computer, tablet, or phone.
You literally said your setup is better than a HWW. If you are using an airgapped wallet, then the security of the internet connected device literally does not matter.
No I didn't, I said it's better than using Linux on your computer.
Go re read the thread my guy.
Phone or Computer x Blue Wallet x SeedSigner
Airgapped = SeedSigner.
Get it now?
Phone or computer x foundation passport
SeedSigner was the reference point for that take
