BTW, are you an official representative of Frostsnap Frontier or are you just someone who likes their products?
I am a Co-Founder of Frostsnap! So feel free to ask any questions.
Thanks for the info, long time lurker first time poster on bitcointalk.
Overcharge price around $150 for a single hardware signer. Dropping it closer to $100 would make the whole set much more attractive.
Could we get the detailed overview of the key features planned for relevant mobile app?
Will the app allow to pair Frostsnap signers with other clients like Sparrow, Electrum, or similar?
The comfort of self-sovereign multisignature in a seamless UX with understandable recovery requirements is well worthwhile.
Costs of other products in a 2-of-3 or collaborative setups can quickly add up to a similar cost.
We've spent spent years engineering, designing and iterating these tools. Early adopters are strongly supporting our mission and we'll look after you well!
Here's a demo video of the app:
https://frostsnap.com/demo.mp4The key features as of now are: distributed key generation, receive, send, verify addresses, PSBT signing, and recovery.
Many more to come including remote signing (shared multisig), inheritance access pathways, limited spending devices.
We'll have more to share on the recovery process soon.
Currently you can only sign with the devices through our app, since FROST is quite an evolution in the integration between signers and coordinators.
But you can export your descriptor to other wallets, craft custom PSBTs (i.e. coin selection) and sign them within our app.
Getting a coordinator into Sparrow or other wallets is certainly a longer-term goal, and crucially our core libraries (as well as other software) is all FOSS.
