Bitcoin-Secure, an open-source Bitcoin financial savings pockets, is now out there, designed for households, people, and firms in search of safe, long-term Bitcoin storage. Targeted 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 consumer 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 targets: to make multisig simpler and to not must depend on Electrum servers,” Griffin informed Bitcoin Journal. The OpenSats grant, operating 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 totally free at bitcoin-safe.org/obtain, suitable 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 approach round a {hardware} pockets,” Griffin acknowledged, emphasizing compatibility with main {hardware} gadgets through QR, USB, or SD card. This units Bitcoin-Secure other than wallets permitting software program seeds, prioritizing safety for important financial savings and minimizing ‘foot weapons’ – options that customers can simply harm themselves with.
The pockets’s multisig setup wizard generates PDFs with pockets descriptors, together with ship and obtain checks for verification. “After you’re executed with this wizard, you possibly can make sure 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 tackle labels throughout gadgets 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 members can share Partially Signed Bitcoin Transactions (PSBTs) with one click on, with relays storing encrypted messages for asynchronous entry.
Coin classes separate funds, reminiscent of KYC trade withdrawals and personal cash, to forestall unintended transaction linkages. “It’s a must to choose the supply of the funds, so that you don’t by accident hyperlink them,” Griffin mentioned, supporting consumer 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 acknowledged. 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 payment information.
The pockets provides keyboard shortcuts, tooltips, and clear error messages. Bug fixes enhance performance, making certain accessibility for novice and superior customers.
Bitcoin-Secure helps real-time conversion for 123 fiat currencies, built-in into the interface. It additionally converts Bitcoin to gold or silver values in ounces and grams. Actual-time mempool alerts notify customers of transaction propagation. “It’s an opt-in function for current customers, opt-out for brand new installations,” Griffin mentioned, with customizable community settings.
Customers can unlock a number of wallets with a single encryption password. “When a number of wallets share the identical encryption password, customers must enter it solely as soon as,” Griffin defined. Nostr’s Chat&Sync function allows distant PSBT coordination for multisig members.
Group and Accessibility
Bitcoin-Secure helps languages like English, Chinese language, and Spanish, with translations through Weblate. Customers can check with tBTC, report bugs, or donate through Lightning or onchain. Engagement happens via Refrain.group and X accounts (@BitcoinSafe, @BitcoinSafeCN), with documentation at bitcoin-safe.org.
Future Improvement: Compact Block Filters
Bitcoin-Secure plans to combine compact block filters in 2025 to interchange Electrum servers. “My plans are to interchange [Electrum servers] with compact block filters to fetch blockchain information straight from Bitcoin Core nodes,” Griffin mentioned, aiming for enhanced privateness and server independence.
