Growth and OpenSats Help
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 must depend on Electrum servers,” Griffin instructed Bitcoin Journal. The OpenSats grant, working 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, suitable with Home windows, macOS, and Linux.
Multisig, {Hardware} Pockets Safety and Coin Management

The pockets’s multisig setup wizard generates PDFs with pockets descriptors, together with ship and obtain checks for verification. “After you’re finished with this wizard, you possibly can make certain 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 high of Nostr to hyperlink these computer systems and synchronize the labels seamlessly,” Griffin famous. Multisig members 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 alternate withdrawals and personal cash, to forestall unintended transaction linkages. “It’s important to choose the supply of the funds, so that you don’t unintentionally hyperlink them,” Griffin mentioned, supporting person privateness.
