Building on bitcoin and nostr

Here is a 2-min video that shows how to create a simple miniscript collaborative custody vault using Smart Vaults

https://youtu.be/wSBMlDqrfaQ

Is there a web nostr client that supports NIP-46 Nostr Connect?

Yes, and built by the same team. We only recently renamed it to “Smart Vaults” because “Coinstr” was too niche and hard to spell.

Why do you think?

The people building it (us) do use nostr. I will create an npub for Smart Vaults specifically. Good call. 👌

We have been building on Nostr for many months now. The signature requests and PSBTs are encrypted and orchestrated over Nostr.

It is open source: https://github.com/coinstr

Smart vaults is built on the Coinstr protocol (uses nostr to orchestrate spending signature requests). Launching soon- sign up for the waiting list here:

https://smartvaults.io

With Coinstr, users encrypt an xpub to share with contacts on Nostr, and then they build spending policies with those keys. Collaborative custody powered by Nostr.

Coinstr is soliciting 10-minute market research calls with any business that owns Bitcoin. Just a few simple questions, and we are offering 100,000 sats for your time.

Your input will be used to refine our open source platform for spending policies and signature orchestration over Nostr.

Please re-post for visibility or DM. Thank you nostriches!!

Highly recommend hledger or other plaint text accounting tools:

Would it make sense to have a standalone site/tool that verified PoR proofs and balances?

If the proof was published as a Nostr note that could be read by the site, or even allow the proof to be pasted in?

Or a Nostr bot that reads them and verifies them.. 🤔

Coinstr implements this library to allow Proof of Reserves to be generated and validated nostr:note13fnw6z2xpvv4a5wwdq85j94fm60kpl7g0q339tk4dgyehxe6p0rqxlg69d

Currently set to a 10 sat admission. No traffic yet but running high perf / high availability. Are you testing or launching?

Bitcoin social recovery policy from my Nostr contacts built with Coinstr

https://void.cat/d/6ZvSwoxFeE6nirBXCgbuNu.webp

Coinstr enables users to build bitcoin Multisig spending policies (miniscript/Tapscript) with their Nostr contacts, then uses Nostr for orchestrating signature requests on proposals.

Nostr uses the same crypto as bitcoin so every client is also a wallet.

See screenshots of or try the policy builder here: https://coinstr.io/articles/coinstr-app-launch/

Build your Bitcoin spending policies from your Nostr contacts. The Coinstr policy builder POC is available at https://coinstr.app.
