The most trusted Bitcoin multisig wallet now comes with the most complete Bitcoin desktop experience ever built. Every wallet, every layer, every key — in one private, locally-run terminal.
Everything a serious Bitcoin holder needs, in one private, offline-capable, open-source desktop application. No accounts. No cloud. No compromise.
Import any wallet — xpub, zpub, single address, hardware wallet, Sparrow or Electrum export. Your complete UTXO picture, built locally. No seed phrase ever enters the app. No address sent to any server.
New in v2.4.2Generate a signed, timestamped PDF — a cryptographically verifiable record of your total Bitcoin holdings. The document long-term holders have always needed for banks, lawyers, and estate planners, without exposing private keys.
New in v2.4.2A private visual timeline of your entire Bitcoin journey. Every wallet, every accumulation era, every price point — rendered as a beautiful chart that never leaves your machine. Your 10-year conviction story, visualized.
New in v2.4.2Base layer BTC, Ordinals inscriptions, Runes, BRC-20 tokens, and Stacks positions — all pulled in and displayed alongside your on-chain holdings. One complete picture across every Bitcoin layer you participate in.
New in v2.4.2Run a full Bitcoin Core node directly from the app with a single click. No command line, no configuration files. Become part of the Bitcoin network infrastructure — verifying transactions, supporting decentralization.
New in v2.4.2Point a small amount of hashrate toward a solo mining pool for a real chance at winning a full block reward. Framed honestly as a participation ticket, not a guaranteed income stream. A principled way to participate in Bitcoin's block production.
New in v2.4.2Full visibility and control over individual UTXOs — label them, freeze them, select specific coins for transactions. Essential for privacy, consolidation strategy, and avoiding address reuse.
Every transaction in your history gets a privacy score — flagging address reuse, change address exposure, and linkability risks. Actionable recommendations for improving your on-chain privacy posture.
Set price targets and net worth milestones. The app sends native system notifications when Bitcoin hits your target. No email, no account, no third-party tracking. Runs silently in the system tray.
For the first time, you can prove what you own to a bank, a lawyer, an estate planner, or your family — without revealing a single private key or connecting to any third-party service. Cryptographically signed, timestamped, and locally generated.
Download for WindowsEvery wallet, every accumulation period, every price point — rendered as a private chart that is stored and processed entirely on your own machine.
Download the installer for Windows, Mac, or Linux. No account required. No email. Just download and run.
Add any wallet via xpub, address, or hardware wallet. Watch-only — your keys never touch the app.
Optionally connect to your own Bitcoin node for fully trustless verification. Or use Tor-routed public nodes.
View your complete Bitcoin picture, generate your holdings certificate, run your node, and manage your security and inheritance planning.
Plug in your hardware wallet and sign transactions directly from the desktop app. No browser extension required.
With a single click, launch a full Bitcoin Core node directly from the application. Verify your own transactions, support network decentralisation, and connect your wallet dashboard to your own node for fully trustless balance verification — no third party required.

"I have held Bitcoin for over a decade and used nearly every wallet available. Nunchuk v2.4.2 is the first time I have had a single screen showing me everything I own — cold storage, Ordinals, Lightning — without trusting a single server. The Proof of Stack feature alone is worth the download."
"The one-click node feature changed how I use Bitcoin. I had been intending to run a node for years. Nunchuk made it a 30-second setup. My entire wallet view is now verified by my own node. This is what genuine self-custody looks like."
"My attorney asked me to document my Bitcoin holdings for an estate plan. Before Nunchuk v2.4.2, there was no clean way to do that without exposing private keys or relying on a third-party service. The holdings certificate resolved a long-standing problem in a single step."
Nunchuk v2.4.2 is free, open source, and available for Windows, Mac, and Linux. No account required. No KYC. No cloud dependency. The most complete Bitcoin desktop application available today.
