Wish there were better airgapped open-source software wallets to participate in your multisig quorum? I've just released a CLI tool built for this purpose.

Demo: https://mf-tmp.s3.amazonaws.com/multiwallet-20201028.html

Feedback welcome!

This is alpha software, testnet is highly recommended.

Once it's stable, I'd still only recommend this for <m of your seeds. It's also a great emergency recovery tool.

You'll notice that it doesn't support single-sig.

Here's an insecure address if you want to send me your testnet bitcoins (not needed, and no promises I'll send them back!): tb1q8whyruu7cq5hekyg7v5fqg6r9e54zq56zwcurdzzgrnfvg0l9euq2l30hf

Thanks to @jimmysong for the early feedback and also for letting me release the amazing buidl library (mostly his code) to buidl this on top of.

Very cool that you can create something so powerful in <1k LOC (mostly presentation). https://github.com/buidl-bitcoin/buidl-python/

Also, if anyone has tips for better ways to record/share your terminal I'd be interested. terminalizer and ttygif are painfully slow and produce enormous file sizes. I used TermRecord for this but it produces (strange) html files, though I do like that you can copy-paste from it.

For CLI ninjas, this is all you need to do to fire it up:

$ git clone [email protected]:buidl-bitcoin/buidl-python.git && cd buidl-python && python http://multiwallet.py 

Notice that installation/dependencies are not needed! Although it's ~100x faster at elliptical curve magic if you install libsecp256k1 (see readme for instructions).
