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?

Open source stays alive – with your help.

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
