OpenSats Grant Fuels Bitcoin-Safe’s Secure Multisig Wallet Launch With Hardware Focus
Bitcoin-Safe, a cutting-edge open-source Bitcoin savings wallet, has hit the market, catering to the needs of families, individuals, and businesses looking for a secure and long-term storage solution for their Bitcoin holdings. This wallet stands out from the crowd with its emphasis on multisig security and the requirement of hardware wallets for mainnet operations, setting it apart from traditional desktop wallets like Electrum and Sparrow. Thanks to the generous support of a one-year OpenSats grant that was awarded in March 2025, Bitcoin-Safe has been able to enhance its security features and revamp its user interface in the latest version, 1.5.0, which was rolled out on September 1, 2025.
Development and OpenSats Support
Andreas Griffin, the mastermind behind Bitcoin-Safe, has been working tirelessly for over two and a half years to bring this innovative wallet to life. His primary goals were to streamline the multisig setup process and reduce dependence on Electrum servers. “I embarked on this wallet journey over two and a half years ago with two main objectives: to simplify multisig setups and eliminate the need for reliance on Electrum servers,” Griffin shared with Bitcoin Magazine. The OpenSats grant, active from March 2025 to March 2026, has been instrumental in supporting Griffin’s vision. Leveraging the Bitcoin Dev Kit (BDK), the wallet’s open-source code is available for auditing on GitHub, and users can download the client for free at bitcoin-safe.org/download, with compatibility across Windows, macOS, and Linux operating systems.
Multisig, Hardware Wallet Security, and Coin Control
Bitcoin-Safe takes security to the next level by enforcing the use of hardware wallets for mainnet operations, thereby disallowing software seeds to mitigate potential security vulnerabilities. Griffin emphasized the importance of hardware wallets for savings, stating that “there is just no way around a hardware wallet.” The wallet is compatible with major hardware devices, allowing for seamless connectivity via QR codes, USB, or SD cards. By prioritizing security for significant savings and minimizing potential risks, Bitcoin-Safe ensures a secure environment for users to store their funds.
The wallet’s multisig setup wizard simplifies the process by generating PDFs containing wallet descriptors and conducting send and receive tests for verification purposes. This meticulous approach guarantees a correctly configured multisig setup without compromising on security. Through the use of the Nostr protocol, Bitcoin-Safe enables the synchronization of transaction and address labels across devices, ensuring end-to-end encryption for enhanced privacy. Participants in a multisig arrangement can effortlessly share Partially Signed Bitcoin Transactions (PSBTs) with a single click, with encrypted messages stored securely for asynchronous access.
To prevent inadvertent transaction linkages, Bitcoin-Safe categorizes funds into different groups, such as KYC exchange withdrawals and private coins. This feature ensures that users select the appropriate fund source to avoid unintentional associations, thereby safeguarding user privacy.
User Interface and Experience
Version 1.5.0 of Bitcoin-Safe introduces a fresh user interface that has been developed in collaboration with @deSign-r. The new interface boasts a sidebar for managing multiple wallets, updated transaction views for sending and signing PSBTs, and a mempool visualization that provides block and fee data at a glance. The addition of keyboard shortcuts, tooltips, and clear error messages enhances the overall user experience. Bug fixes have been implemented to improve functionality and ensure that both novice and advanced users can navigate the wallet with ease.
Bitcoin-Safe offers real-time conversion for 123 fiat currencies, seamlessly integrated into the interface. Users can also convert their Bitcoin holdings into gold or silver values in ounces and grams. Real-time mempool alerts notify users about transaction propagation, with the feature being optional for existing users and opt-out for new installations. Customizable network settings provide users with the flexibility to tailor their experience according to their preferences.
Users can conveniently unlock multiple wallets with a single encryption password, streamlining the authentication process. The Nostr Chat&Sync feature enables remote coordination of PSBTs for multisig participants, further enhancing the collaborative aspect of the wallet.
Community and Accessibility
Bitcoin-Safe is committed to supporting a diverse range of languages, including English, Chinese, and Spanish, with translations facilitated through Weblate. Users are encouraged to participate in testing with tBTC, report any bugs they encounter, and contribute via Lightning or onchain donations. Engagement with the community takes place through platforms like Chorus.community and X accounts (@BitcoinSafe, @BitcoinSafeCN), with comprehensive documentation available at bitcoin-safe.org.
Future Development: Compact Block Filters
Looking ahead, Bitcoin-Safe has ambitious plans to integrate compact block filters in 2025, with the aim of replacing Electrum servers. Griffin envisions a future where blockchain data can be fetched directly from Bitcoin Core nodes, thereby enhancing privacy and reducing dependence on external servers. This strategic move underscores Bitcoin-Safe’s commitment to staying at the forefront of technological advancements in the cryptocurrency space.
In conclusion, Bitcoin-Safe represents a significant leap forward in the realm of Bitcoin savings wallets, offering unparalleled security, user-friendly features, and a robust infrastructure that caters to the diverse needs of individuals, families, and businesses alike. With a relentless focus on innovation and a commitment to excellence, Bitcoin-Safe is poised to revolutionize the way users store and manage their Bitcoin holdings. The Importance of Mental Health Awareness
Mental health is just as important as physical health, yet it is often overlooked and stigmatized in society. It is crucial to raise awareness about mental health in order to break down these barriers and ensure that individuals receive the support and resources they need to thrive.
One of the key reasons why mental health awareness is so important is because mental health issues are extremely common. According to the World Health Organization, one in four people will experience a mental health condition at some point in their lives. This means that mental health issues affect a significant portion of the population, and it is essential that we address these issues in order to prevent them from escalating and causing further harm.
Furthermore, mental health issues can have a profound impact on a person’s overall well-being. Depression, anxiety, and other mental health conditions can affect a person’s ability to function in their daily lives, impacting their relationships, work, and overall quality of life. By raising awareness about mental health, we can help individuals recognize the signs and symptoms of mental health issues and seek the help they need to recover.
Another reason why mental health awareness is important is because it can help reduce the stigma surrounding mental health. Many people are hesitant to seek help for mental health issues due to fear of judgment or discrimination. By promoting awareness and education about mental health, we can help break down these barriers and create a more supportive and inclusive environment for those struggling with mental health issues.
In addition, mental health awareness can also help promote early intervention and prevention strategies. By educating individuals about the importance of mental health and providing them with the tools and resources to maintain their mental well-being, we can help prevent mental health issues from escalating and becoming more severe.
Overall, mental health awareness is crucial for promoting the well-being of individuals and communities. By raising awareness about mental health, we can help reduce stigma, promote early intervention, and ensure that individuals receive the support and resources they need to thrive. It is important that we continue to prioritize mental health awareness and work towards creating a more supportive and compassionate society for all.
