Bitcoin Safe, an open-source Bitcoin savings wallet, is now available, offering a secure long-term storage solution for families, individuals, and companies. The wallet emphasizes multi-signature security and requires hardware wallets for mainnet operations, distinguishing it from other desktop wallets like Electrum and Sparrow. Supported by a one-year Open Sets grant awarded in March 2025, Bitcoin Safe released its latest version 1.5.0 on September 1, 2025, featuring enhanced security and a redesigned user interface. Developed over two years by Andreas Grafen, the wallet aims to simplify multi-sig setups while reducing reliance on Electrum servers. The Open Sets grant supports development from March 2025 to March 2026. Built on the Bitcoin Development Kit (BDK), the wallet is fully open source with code available on GitHub and free clients for Windows, macOS, and Linux.
Bitcoin Safe mandates hardware wallets on the mainnet to mitigate security risks and does not permit software seeds. It supports hardware devices via QR codes, USB, or SD cards. Additionally, the wallet generates PDF wallet descriptors through a multi-sig setup wizard, enabling users to verify wallets easily and securely. Using the Nostr protocol, Bitcoin Safe synchronizes transactions and address labels across devices with end-to-end encryption. Multi-sig participants can share partially signed Bitcoin transactions (PSBTs) with one click, while release-encrypted messages remain protected. Coin categories segregate funds to preserve user privacy and prevent unwanted transaction linking.
The new update improves the user interface with features such as multi-wallet management, transaction views, mempool visualization, keyboard shortcuts, and clear error messages. It also supports real-time conversion for 123 fiat currencies and allows users to convert Bitcoin into equivalent gold or silver amounts. Bitcoin Safe offers community support in English, Chinese, and Spanish, enabling users to report bugs, test features, and contribute via Lightning or on-chain donations. Future plans include replacing Electrum servers with compact block filters to fetch blockchain data directly from Bitcoin Core nodes, enhancing privacy and reducing server dependency.
