Bitcoin-SafeOpen-source Bitcoin wallets are now available for individuals, families and businesses who want to store Bitcoins securely over a long period of time. It is different from desktop wallets such as Electrum or Sparrow because it focuses on multisignature security. Bitcoin-Safe, which was awarded a year-long OpenSats grant in March 2025 and released its 1.5.0 version on September 1 2025, combines robust encryption with an improved user interface.
OpenSats Development Support
Bitcoin-Safe, developed by Andreas Griffin for more than two years and a half, aims to reduce reliance on Electrum server and simplify multisig settings. “I started over two and a half years ago with this wallet and I had two goals: to make multisig easier and to not need to rely on Electrum servers,” Griffin spoke to Bitcoin Magazine. The Bitcoin Magazine reported that Griffin. OpenSats The grant will run from March 20, 2025 until March 20, 2026. The wallet is built on Bitcoin Dev Kit. Its code can be audited on GitHub and installable clients are available for free at bitcoin-safe.org/download, compatible with Windows, macOS, and Linux.
Secure Hardware Wallet with Multisignature and Coin Control
Bitcoin-Safe prohibits the use of software seeds and enforces only hardware wallets in mainnet. “For savings, there is just no way around a hardware wallet,” Griffin emphasized compatibility via USB or SD cards, QR codes, and major hardware devices. This sets Bitcoin-Safe apart from wallets allowing software seeds, prioritizing security for significant savings and minimizing ‘foot guns’ – features that users can easily hurt themselves with.
The multisig wallet setup wizard creates PDFs that include wallet descriptions, as well as send and receive test for verification. “After you’re done with this wizard, you can be sure that it’s set up correctly,” Griffin added. The configuration is reliable, allowing multisig to be accessible while maintaining security.
Bitcoin-Safe synchronizes address and transaction labels encrypted from end-to-end across multiple devices using the Nostr protocols. “I created a protocol on top of Nostr to link these computers and synchronize the labels seamlessly,” Griffin stated. Griffin noted.
To prevent accidental transaction linking, coin categories should be separated from funds such as KYC withdrawals, private coins and exchange withdrawals. “You have to select the source of the funds, so you don’t accidentally link them,” Griffin Says Supporting User Privacy
User Experience and Interface
Version 1.5.0 brings a brand new user interface developed in conjunction with @deSign-r. “The designer who joined the project really contributes massively,” Griffin explained. The sidebar allows users to manage multiple wallets. It also includes updated views of transactions for signing and sending PSBTs and mempool data visualization.
This wallet now includes keyboard shortcuts and tooltips. It also has clear error messages. This version includes bug fixes that improve the functionality of both novice and advanced users.
Integrated into the interface, Bitcoin-Safe offers real-time exchange rates for 123 fiat currencys. Also, it converts Bitcoins to the equivalent in gold or silver in terms of ounces or grams. Users are notified of the propagation of transactions by real-time alerts from mempools. “It’s an opt-in feature for existing users, opt-out for new installations,” Griffin, with network configurations that can be customized.
With a single password, users can open multiple wallets. “When multiple wallets share the same encryption password, users need to enter it only once,” Griffin explained. Nostr’s Chat&Sync feature enables remote PSBT coordination for multisig participants.

They can also report bugs or test the software with tBTC. Users can engage with Chorus.community, X (@BitcoinSafeCN and @BitcoinSafeCN) accounts. Documentation is available at bitcoin-safe.org.
Compact Block Filters: Future Development
Bitcoin-Safe will replace Electrum servers with compact block filters by 2025. “My plans are to replace [Electrum servers] with compact block filters to fetch blockchain data directly from Bitcoin Core nodes,” Griffin’s goal was to enhance privacy while maintaining server independence.
