I've seen a lot of hype over Anonero from the amazing #Monero community, and it reminded me a lot of #SeedSigner.

One of the most noticeable differences, of course, is that you could simply use two phones instead of needing to assemble a separate device entirely (RaspPi or the like).

Has anyone built anything similar for #Bitcoin? A pair of apps on two separate devices (one online, one offline) that can securely sign transactions?

Samourai Wallet + "Sentinel" watch-only wallet combo

Samourai can hold your private keys on a completely offline device (disable internet connection with GrapheneOS or rip out the wifi chip), yet you can still sign transactions created on another device that has Sentinel (similar to how you do with SeedSigner)

Sounds like a great combination. Thanks for the tip. Hope to mess around with that soon!
