Bitcoin-Safe, an open-source Bitcoin financial savings pockets, is now accessible, designed for households, people, and firms looking for safe, long-term Bitcoin storage. Centered on multisig safety and requiring {hardware} wallets for mainnet operations, it distinguishes itself from different desktop wallets like Electrum and Sparrow. Supported by a one-year OpenSats grant awarded in March 2025, Bitcoin-Secure combines sturdy safety with a redesigned person interface in its newest model, 1.5.0, launched on September 1, 2025.
Improvement and OpenSats Help
Developed for over two and a half years by Andreas Griffin, Bitcoin-Secure goals to simplify multisig setups and scale back reliance on Electrum servers. “I began over two and a half years in the past with this pockets and I had two objectives: to make multisig simpler and to not have to depend on Electrum servers,” Griffin informed Bitcoin Journal. The OpenSats grant, working from March 2025 to March 2026, helps these efforts. Constructed on Bitcoin Dev Equipment (BDK), the pockets’s open-source code is auditable on GitHub and installable purchasers can be found free of charge at bitcoin-safe.org/obtain, appropriate with Home windows, macOS, and Linux.
Multisig, {Hardware} Pockets Safety and Coin Management
Bitcoin-Secure enforces {hardware} wallets for mainnet, prohibiting software program seeds to mitigate safety dangers. “For financial savings, there may be simply no means round a {hardware} pockets,” Griffin said, emphasizing compatibility with main {hardware} units through QR, USB, or SD card. This units Bitcoin-Secure other than wallets permitting software program seeds, prioritizing safety for vital financial savings and minimizing ‘foot weapons’ – options that customers can simply damage themselves with.
The pockets’s multisig setup wizard generates PDFs with pockets descriptors, together with ship and obtain assessments for verification. “After you’re carried out with this wizard, you possibly can ensure that it’s arrange appropriately,” Griffin mentioned. This ensures dependable configuration, making multisig accessible with out compromising safety.
Utilizing the Nostr protocol, Bitcoin-Secure syncs transaction and deal with labels throughout units encrypted finish to finish. “I created a protocol on prime of Nostr to hyperlink these computer systems and synchronize the labels seamlessly,” Griffin famous. Multisig contributors can share Partially Signed Bitcoin Transactions (PSBTs) with one click on, with relays storing encrypted messages for asynchronous entry.
Coin classes separate funds, akin to KYC trade withdrawals and personal cash, to forestall unintended transaction linkages. “It’s important to choose the supply of the funds, so that you don’t by accident hyperlink them,” Griffin mentioned, supporting person privateness.
Consumer Interface and Expertise
Model 1.5.0 introduces a brand new interface, developed with @deSign-r. “The designer who joined the challenge actually contributes massively,” Griffin said. Options embody a sidebar for managing a number of wallets, up to date transaction views for sending and signing PSBTs, and a mempool visualization displaying block and price information.
The pockets provides keyboard shortcuts, tooltips, and clear error messages. Bug fixes enhance performance, making certain accessibility for novice and superior customers.
