πŸš€ Today we’re supporting nostr:npub1q67f4d7qdja237us384ryeekxsz88lz5kaawrcynwe4hqsnufr6s27up0e

from Bitcoin-Safe.Org with 1,000,000 satoshis for his work on Bitcoin Safe – a beginner-friendly multisig wallet for Mac, Windows, Linux, or anywhere Python runs. Why this matters πŸ§΅πŸ‘‡

πŸ”§ Development of Specter Desktop is no longer a priority at Swan. A vital open-source wallet has essentially become abandonware – leaving a painful gap in the Bitcoin ecosystem.

πŸ’‘ Andreas, a former Specter developer himself, recognized this gap – and with Bitcoin Safe created a brand-new solution that already goes beyond what Specter offered.

πŸ”’ What makes Bitcoin Safe special:

An open-source wallet focused on multisig and hardware wallet integration. It combines the strengths of Electrum, Specter, and @mempool – with Nostr functionality added in.

πŸ§™ The beginner-friendly multisig wizard makes secure Bitcoin self-custody accessible – even for non-technical users.

πŸ–ΌοΈ The graphical transaction display isn’t just functional, it’s beautiful. Even better than Sparrow! For Bitcoin artists like Fractal_Encrypt and nostr:npub1yp7wfa7msdpusf4vupzttttu2mx3cns7whx5cgkt4yr9pkpvujus2mzys7 it can be exported as vector graphics.

🌐 But the real gamechanger is the Nostr integration – enabling secure, decentralized PSBT exchange between cosigners.

🌐 It’s comparable to Electrum’s Cosigner Pool or nunchuk's proprietary chat – but here: fully open source, set up in seconds, and run via encrypted Nostr DMs.

πŸ”— Not just PSBTs – UTXO labels can be shared via Nostr too. A key building block for collaboration in multisig setups.

🌍 We’d love to see other wallet clients adopt this Nostr sync functionality as well – to increase client diversity, especially for organizations with varying needs.

πŸ› οΈ Bitcoin Safe delivers this critical workflow entirely open source – built on the decentralized Nostr protocol. A milestone for sovereignty in the Bitcoin ecosystem.

🀝 Open-source Bitcoin projects are chronically underfunded. That’s why it’s so important to support developers like Andreas who push boundaries and define new standards. Bitcoin Safe πŸ’ͺ

πŸ“£ Our support of 1,000,000 satoshis is meant to send a message:

High-quality open-source development deserves funding.

2 out of 5 cosigners signed this transaction using Bitcoin Safe. Who’s next?

Thanks so much guysπŸ™

Lots of cool stuff in development, like

- Compact Block Filters! Fast and much more private than electrum servers .

Big thanks also to the nostr:nprofile1qqsgkmgkmv63djkxmwvdlyaxx0xtsytvkyyg5fwzmp48pwd30f3jtxspzemhxue69uhhyetvv9ujuurjd9kkzmpwdejhgqg5waehxw309aex2mrp0yhxgctdw4eju6t0qyt8wumn8ghj7un9d3shjtnwdaehgu3wvfskueqr8vuet

team, who are the reliable basis for http://Bitcoin-Safe.org

Compact Block Filters?

Another thing on my learning to doπŸ˜…

Very cool. Well done :)

Thanks for hhjs public service announcement

Very much appreciate the new option to Electrum & Sparrow! Choices are good. Thank you πŸ™ Personally though, I would be cautious of trusting the encryption of Nostr DMs to protect the privacy of sensitive PSBTs.

You can set your own relay if you'd like.

Thank you for this information! I'm glad to hear Nostr integration is opt in. I look forward to Nostr DM encryption becoming more robust in the future. Thank you again for all you're doing in support of bitcoin πŸ™

It's off by default

Congrats, Andreas! Thank you for all of your hard work πŸ™

Just had a longer conversation with Andreas, solving a problem with the 1.1 version and OSX (14.1) - solved now, he told me he will bring out 1.2 anytime soon.

Great to work with true bitcoiners all over the world.

No te metas con mi marido Sparrow 😑

FYI, our group wallet + chat is not proprietary.

It is open source and built on BIP129 (which we co-authored). More information in this blog: https://nunchuk.io/blog/group-wallet
