Bitcoin-SAFE, an open source bitcoin savings wallet, is now available, designed for families, individuals and companies that seek safe long-term storage of Bitcoin. Focused on multisig safety and requires hardware wallets for Mainnet operations, it is distinguished from other desktop wallets such as Electrum and Sparrow. With the support of a one-year OpenSats subsidy granted in March 2025, Bitcoin-SAfe combines robust security with a redesigned user interface in its latest version, 1.5.0, launched on September 1, 2025.
Development and Opening Support
Developed for more than two and a half years by Andreas Griffin, Bitcoin-SAfe aims to simplify Multisig settings and reduce the dependence of electrum servers. “I started more than two and a half years ago with this wallet and had two objectives: making Multisgig easier and not having to trust electrum servers,” Griffin told Bitcoin magazine. The Opensats subsidy, which extends from March 2025 to March 2026, supports these efforts. Built in Bitcoin Dev Kit (BDK), the open wallet’s open source code is auditable in Github and installation customers are available for free in Bitcoin-safe.org/download, compatible with Windows, Macos and Linux.
Multisig, hardware and currency control wallet
Bitcoin-Safe Applies Hardware wallets for Mainnet, which prohibits software seeds to mitigate safety risks. “For savings, there is no way to avoid a hardware wallet,” Griffin said, emphasizing compatibility with the main hardware devices through the QR card, USB or SD. This distinguishes Bitcoin Safe from wallets that allow software seeds, prioritize security for significant savings and minimize ‘floors’ guns’, features with which users can easily be damaged.
The Wallet Multisig configuration assistant generates PDF with wallet descriptors, including shipping and reception tests for verification. “After this assistant is over, he may be sure that he is configured correctly,” Griffin said. This guarantees a reliable configuration, which makes Multisig accessible without compromising security.
Using the Nostr protocol, transaction labels and safe synchronization of Bitcoins through end -to -end devices. “I created a protocol in addition to Nostr to link these computers and synchronize labels without problems,” Griffin said. Multisig participants can share bitcoin transactions (PSBT) partially signed with a single click, with relays storing encrypted messages for asynchronous access.
The categories of currencies separate the funds, such as KYC exchange withdrawals and private currencies, to avoid unwanted transaction links. “You must select the source of the funds, so that you do not accidentally link them,” said Griffin, admitting user privacy.
User and experience interface
Version 1.5.0 presents a new interface, developed with @Design-R. “The designer who joined the project really contributes massively,” Griffin said. The features include a sidebar to administer multiple wallets, updated transactions views to send and sign PSBTS, and a mempool display that shows block data and rates.
The wallet adds direct keyboard accesses, information on tools and deleted error messages. Errors corrections improve functionality, ensuring accessibility for rookie and advanced users.
Bitcoin-SAFE admits real-time conversion for 123 fiduciary currencies, integrated into the interface. It also converts Bitcoin’s values into gold or silver into ounces and grams. Mempool alerts in real time notifies users of transactions spread. “It is a subscription function for existing users, opting for new facilities,” said Griffin, with customizable network settings.
Users can unlock multiple wallets with a single encryption password. “When multiple wallets share the same encryption password, users must enter it only once,” Griffin explained. The chat and synchronization function of Nostr allows PSBT’s remote coordination for Multisig participants.
Community and accessibility
Bitcoin-Safe admits languages such as English, Chinese and Spanish, with translations through weblate. Users can try TBTC, inform errors or donate through Lightning or Ochain. The commitment occurs through chorus.community and x accounts (@bitcoinsafe, @bitcoinfecn), with documentation in Bitcoin-safe.org.
Future Development: Compact Block Filters
Bitcoin-SAFE plans to integrate compact block filters in 2025 to replace electrum servers. “My plans are replacing [Electrum servers] With compact block filters to obtain blockchain data directly from Bitcoin nodes, “said Griffin, with the aim of greater privacy and independence of the server.
