Bitcoin-Secure, an open-source Bitcoin financial savings pockets, is now obtainable, designed for households, people, and corporations in search of 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 strong safety with a redesigned person interface in its newest model, 1.5.0, launched on September 1, 2025.
Improvement and OpenSats Assist
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 instructed Bitcoin Journal. The OpenSats grant, working from March 2025 to March 2026, helps these efforts. Constructed on Bitcoin Dev Package (BDK), the pockets’s open-source code is auditable on GitHub and installable purchasers can be found at no cost 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’s simply no means round a {hardware} pockets,” Griffin acknowledged, 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 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 completed with this wizard, you may ensure that it’s arrange accurately,” Griffin stated. 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 members can share Partially Signed Bitcoin Transactions (PSBTs) with one click on, with relays storing encrypted messages for asynchronous entry.
Coin classes separate funds, resembling KYC trade withdrawals and personal cash, to forestall unintended transaction linkages. “You need to choose the supply of the funds, so that you don’t by accident hyperlink them,” Griffin stated, 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 undertaking actually contributes massively,” Griffin acknowledged. Options embrace 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 knowledge.
The pockets provides keyboard shortcuts, tooltips, and clear error messages. Bug fixes enhance performance, guaranteeing 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 characteristic for current customers, opt-out for brand spanking new installations,” Griffin stated, 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 have to enter it solely as soon as,” Griffin defined. Nostr’s Chat&Sync characteristic permits distant PSBT coordination for multisig members.

Engagement happens by means of Refrain.neighborhood 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 exchange Electrum servers. “My plans are to exchange [Electrum servers] with compact block filters to fetch blockchain knowledge immediately from Bitcoin Core nodes,” Griffin stated, aiming for enhanced privateness and server independence.
