Bitcoin-Protected, an open-source Bitcoin financial savings pockets, is now out there, designed for households, people, and firms in search of safe, long-term Bitcoin storage. Targeted on multisig safety and requiring {hardware} wallets for mainnet operations, it distinguishes itself from different desktop wallets like Electrum and Sparrow. Supported by a one-year OpenSats grant awarded in March 2025, Bitcoin-Protected combines strong safety with a redesigned consumer interface in its newest model, 1.5.0, launched on September 1, 2025.
Growth and OpenSats Assist
Developed for over two and a half years by Andreas Griffin, Bitcoin-Protected goals to simplify multisig setups and scale back reliance on Electrum servers. “I began over two and a half years in the past with this pockets and I had two targets: to make multisig simpler and to not must depend on Electrum servers,” Griffin informed Bitcoin Journal. The OpenSats grant, working from March 2025 to March 2026, helps these efforts. Constructed on Bitcoin Dev Package (BDK), the pockets’s open-source code is auditable on GitHub and installable shoppers can be found totally free at bitcoin-safe.org/obtain, suitable with Home windows, macOS, and Linux.
Multisig, {Hardware} Pockets Safety and Coin Management
Bitcoin-Protected enforces {hardware} wallets for mainnet, prohibiting software program seeds to mitigate safety dangers. “For financial savings, there may be simply no method round a {hardware} pockets,” Griffin acknowledged, emphasizing compatibility with main {hardware} units by way of QR, USB, or SD card. This units Bitcoin-Protected other than wallets permitting software program seeds, prioritizing safety for important financial savings and minimizing ‘foot weapons’ – options that customers can simply damage themselves with.
The pockets’s multisig setup wizard generates PDFs with pockets descriptors, together with ship and obtain assessments for verification. “After you’re achieved with this wizard, you may make sure that it’s arrange appropriately,” Griffin mentioned. This ensures dependable configuration, making multisig accessible with out compromising safety.
Utilizing the Nostr protocol, Bitcoin-Protected syncs transaction and handle labels throughout units encrypted finish to finish. “I created a protocol on high of Nostr to hyperlink these computer systems and synchronize the labels seamlessly,” Griffin famous. Multisig contributors can share Partially Signed Bitcoin Transactions (PSBTs) with one click on, with relays storing encrypted messages for asynchronous entry.
Coin classes separate funds, equivalent to KYC alternate withdrawals and personal cash, to stop unintended transaction linkages. “You need to choose the supply of the funds, so that you don’t unintentionally hyperlink them,” Griffin mentioned, supporting consumer privateness.
Consumer Interface and Expertise
Model 1.5.0 introduces a brand new interface, developed with @deSign-r. “The designer who joined the challenge actually contributes massively,” Griffin acknowledged. Options embody a sidebar for managing a number of wallets, up to date transaction views for sending and signing PSBTs, and a mempool visualization exhibiting block and charge knowledge.
The pockets provides keyboard shortcuts, tooltips, and clear error messages. Bug fixes enhance performance, guaranteeing accessibility for novice and superior customers.
Bitcoin-Protected helps real-time conversion for 123 fiat currencies, built-in into the interface. It additionally converts Bitcoin to gold or silver values in ounces and grams. Actual-time mempool alerts notify customers of transaction propagation. “It’s an opt-in function for present customers, opt-out for brand spanking new installations,” Griffin mentioned, with customizable community settings.
