Say hello to Igloo Web - the easiest and most lightweight way to run a Frostr signer!


https://iglooweb.app

Here's a diagram I made for NIP-46 signing flow with Frostr...
- nostr client sends nip46 request to relay
- igloo server listens for nip46 request
- approves
- passes to other signer (igloo-cli) for partial sig
- gets response from cli and completes sig
- passes back to relay
- nostr client receives signed note and publishes to relays

All of thise happens within like 2 seconds wtf

Yes they are! - @nevent1qvz...

Key rotation is done manually still - you need the threshold of shares within that keyset (2/3 for example) locally in order to recover the nsec, this does not happen over nostr in some fancy protocol manner (only signing does)

shares are only valid within a keyset meaning that if you have a 2/3 and you lose a share IF you destroy the other 2 shares than the third stolen share is ORPHANED.

So to rotate at this time the steps are:
- Recover nsec with threshold of shares
- Use that nsec to generate a new keyset (can be any threshold)
- DESTROY the shares in the old keyset

TLDR; DESTROY AND OPRHAN

Legend! TY 🤝

Here is our demo from Bitcoin 2025 this might help! https://www.youtube.com/watch?v=J1WG_InBsHg

Split your nsec into a multisig
The keys of that multisig talk to each other over nostr to sign notes

Rumors that first version of Frostr android signer will be released next week!?!?! Can't trust what you hear nowadays though...

Happy Friday - Frostr can now run on Umbrel ❄️ 🤝 ☂️

Version 1.1.0 of igloo-server can now be added as an easy to run app on your Umbrel through the Community App Stores feature.

Just click on the ... in the top right of app store and add https://github.com/frostr-org/igloo-server-store as the url - then install and you'll be up and running in no time!

Gotta have that dawg in you

Also yes, frostr uses frostr for nostr. We eating our dogfood now!
