Bitcoin Magazine OpenSats Grant Fuels Bitcoin-Safe’s Secure Multisig Wallet Launch with Hardware Focus Bitcoin-Safe, an open-source Bitcoin savings wallet, is now available, designed for families, individuals, and companies seeking secure, long-term Bitcoin storage. Focused on multisig security and requiring hardware wallets for mainnet operations, it distinguishes itself from other desktop wallets like Electrum and Sparrow. Supported by a one-year OpenSats grant awarded in March 2025, Bitcoin-Safe combines robust security with a redesigned user interface in its latest version, 1.5.0, released on September 1, 2025. Development and OpenSats Support Developed for over two and a half years by Andreas Griffin, Bitcoin-Safe aims to simplify multisig setups and reduce reliance on Electrum servers. “I started over two and a half years ago with this wallet and I had two goals: to make multisig easier and to not need to rely on Electrum servers,” Griffin told Bitcoin Magazine. The OpenSats grant, running from March 2025 to March 2026, supports these efforts. Built on Bitcoin Dev Kit (BDK), the wallet’s open-source code is auditable on GitHub and installable clients are available for free at bitcoin-safe.org/download, compatible with Windows, macOS, and Linux. Multisig, Hardware Wallet Security and Coin Control Bitcoin-Safe enforces hardware wallets for mainnet, prohibiting software seeds to mitigate security risks. “For savings, there is just no way around a hardware wallet,” Griffin stated, emphasizing compatibility with major hardware devices via QR, USB, or SD card. This sets Bitcoin-Safe apart from wallets allowing software seeds, prioritizing security for significant savings and minimizing ‘foot guns’ – features that users can easily hurt themselves with. The wallet’s multisig setup wizard generates PDFs with wallet descriptors, including send and receive tests for verification. “After you’re done with this wizard, you can be sure that it’s set up correctly,” Griffin said. This ensures reliable configuration, making multisig accessible without compromising security. Using the Nostr protocol, Bitcoin-Safe syncs transaction and address labels across devices encrypted end to end. “I created a protocol on top of Nostr to link these computers and synchronize the labels seamlessly,” Griffin noted. Multisig participants can share Partially Signed Bitcoin Transactions (PSBTs) with one click, with relays storing encrypted messages for asynchronous access. Coin categories separate funds, such as KYC exchange withdrawals and private coins, to prevent unintended transaction linkages. “You have to select the source of the funds, so you don’t accidentally link them,” Griffin said, supporting user privacy.
