Final on Nostr: Not technically perfect or exact to the topic but want to see a #GrapheneOS device ...
Not technically perfect or exact to the topic but want to see a #GrapheneOS device with a secondary display and secure element for hardware wallet functionality. It could just be a phone and a device like a Trezor Safe 5 separately in the same housing. Secondary touchscreen for transactions would be on the back next to camera.
Users could use their own official wallet app if it's just bundling an existing one but an app oriented around the device would be nice for it. Only disadvantage is that the HWW wouldn't fully be integrated with the OS (good and bad), like duress password wiping the wallet at the same time likely not possible because they should be isolated.
From technical aspects the wallet app should support privacy features like coinjoins, stealth addresses. Support for multisig and all the big external HWWs. App needs to be fully compatible with OS security features, unfortunately some still break with MTE. If the HWW and app had Nostr key management then it's a bonus. App developer could choose to bundle self-custodial Lightning. I really like how easy Phoenix is but there is dependence of their infrastructure for transactions.
I'd prefer the UI of neobank apps but less cluttered. All these apps use the same kind of UIs because they work. Cryptocurrencies need the same experience and feel as handling fiat currencies to succeed else "normies" don't onboard because their apps are unfamiliar. They don't get treated or developed to be used like currencies most of the time and that's a problem. Treat separate currencies like separate accounts, and the wallets of them like separate virtual cards, and
Other features or details need to be:
- Fast and easy swaps from L1 <-> L2 with support for other assets, purchasing from fiat. Cake does good with swaps.
- Reproducible builds
- Encrypting application data with a secure passphrase (optional).
- Privacy network integration (usually Tor)
- NFC tap-to-pay
- Fast and, I can't stress this enough, easy backups
- Device hardware attestation support, like what we do with Auditor. The app could design to have potential safeguards for attestation failure as an advanced feature.
- Home widgets.
- View-only support
