The just recently released Bitcoin-Safe, an open-source Bitcoin cost savings wallet, deals with households, people, and business looking for secure, long-lasting storage services. Emphasizing multisignature (multisig) security and mandating the usage of hardware wallets for mainnet operations, Bitcoin-Safe sets itself apart from other desktop wallets, such as Electrum and Sparrow. Backed by a one-year OpenSats grant awarded in March 2025, Bitcoin-Safe combines robust security functions with a revamped interface in its newest variation, 1.5.0, which was launched on September 1, 2025.
Development and OpenSats Support
Developed over a period of more than 2 and a half years by Andreas Griffin, Bitcoin-Safe looks for to streamline the multisig setup procedure while reducing reliance on Electrum servers. Griffin articulated his vision for the wallet: “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.” The continuous OpenSats grant, which ranges from March 2025 to March 2026, reinforces these developmental efforts. Built on the Bitcoin Development Kit (BDK), the wallet’s open-source code is auditable on GitHub, and customers are readily available free of charge at bitcoin-safe.org/download, suitable with Windows, macOS, and Linux.
Multisig, Hardware Wallet Security, and Coin Control
Bitcoin-Safe mandates the usage of hardware wallets for mainnet operations, consequently restricting software application seeds to alleviate security threats. Griffin stressed the need of this technique, specifying, “For savings, there is just no way around a hardware wallet.” The wallet works with significant hardware gadgets through QR, USB, or SD card connections, which improves its security posture for considerable cost savings while reducing the capacity for user mistakes.
The wallet’s multisig setup wizard creates PDFs consisting of wallet descriptors, along with send out and get tests for confirmation. “After you’re done with this wizard, you can be sure that it’s set up correctly,” Griffin verified, guaranteeing that users can dependably set up the multisig function without jeopardizing security.
Utilizing the Nostr procedure, Bitcoin-Safe offers integrated deal and address labels throughout gadgets with end-to-end file encryption. Griffin kept in mind, “I created a protocol on top of Nostr to link these computers and synchronize the labels seamlessly.” This performance allows multisig individuals to share Partially Signed Bitcoin Transactions (PSBTs) with a single click, while relays keep encrypted messages for asynchronous gain access to.
Coin classifications help in separating funds for different functions, such as KYC exchange withdrawals and personal coins, consequently avoiding unintentional deal linkages. “You have to select the source of the funds, so you don’t accidentally link them,” Griffin mentioned, highlighting the significance of user personal privacy.

This upgrade also presents keyboard faster ways, tooltips, and clearer mistake messages. Various bug repairs improve general performance, making the wallet more available to both amateur and advanced users.
Bitcoin-Safe helps with real-time conversion throughout 123 fiat currencies, which is incorporated straight into the interface. Additionally, it permits the conversion of Bitcoin into silver or gold worths in ounces and grams. Real-time mempool signals keep users notified about deal proliferation, explained by Griffin as “an opt-in feature for existing users, opt-out for new installations,” along with adjustable network settings.
Users can open several wallets utilizing a single file encryption password, as discussed by Griffin: “When multiple wallets share the same encryption password, users need to enter it only once.” The combination of Nostr’s Chat&Sync function also permits remote PSBT coordination amongst multisig individuals.

Future Development: Compact Block Filters
Looking ahead, Bitcoin-Safe prepares to carry out compact block filters in 2025 to change Electrum servers. Griffin mentioned, “My plans are to replace [Electrum servers] with compact block filters to fetch blockchain data directly from Bitcoin Core nodes,” with an objective to improve user personal privacy and decrease reliance on external servers.
