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 objectives: to make multisig simpler and to not have to depend on Electrum servers,” Griffin advised Bitcoin Journal. The OpenSats grant, operating from March 2025 to March 2026, helps these efforts. Constructed on Bitcoin Dev Equipment (BDK), the pockets’s open-source code is auditable on GitHub and installable shoppers can be found at no cost at bitcoin-safe.org/obtain, appropriate with Home windows, macOS, and Linux.
Multisig, {Hardware} Pockets Safety and Coin Management

This units Bitcoin-Protected aside from wallets permitting software program seeds, prioritizing safety for vital 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 exams for verification. “After you’re finished with this wizard, you may ensure that it’s arrange accurately,” 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 prime of Nostr to hyperlink these computer systems and synchronize the labels seamlessly,” Griffin famous. Multisig individuals can share Partially Signed Bitcoin Transactions (PSBTs) with one click on, with relays storing encrypted messages for asynchronous entry.
Coin classes separate funds, corresponding to KYC trade withdrawals and personal cash, to stop unintended transaction linkages. “You must choose the supply of the funds, so that you don’t by chance hyperlink them,” Griffin mentioned, supporting consumer privateness.
