What is Nunchuk?
Nunchuk is a bitcoin wallet app for do-it-yourself single-sig and multisig wallets, free of charge. Paid plans add assisted multisig: Iron Hand ($120/year) sets up a 2-of-3 wallet, and Honey Badger ($480/year) adds 2-of-4 wallets with an inheritance key and an on-chain or off-chain timelock. Its Android app code is public under GPL-3.0.
How Nunchuk works
Nunchuk's apps are built on libnunchuk, a C++ multisig library that reuses Bitcoin Core code.
On the free tier you assemble your own single-sig or multisig wallet from signers you choose. Paid plans add assisted wallets with a key health check, automated key replacement and wallet rollover, a configurable broadcast delay and an emergency lockdown.
Honey Badger adds an inheritance key and makes you pick one of two protocols at setup. Autonomous recovery uses an on-chain timelock enforced by the Bitcoin network, needs Miniscript-compatible keys and still works if Nunchuk is unavailable. Flexible recovery uses an off-chain timelock with Nunchuk's assisted claim process, and lets you split an inheritance across beneficiaries and dates.
How to start with Nunchuk
- Install Nunchuk on iPhone, Android or desktop.
- The App Store listing says it asks for no personal data beyond an email and no KYC.
- Paid plans can be tried on testnet for free first.
- Iron Hand needs two hardware keys, such as TAPSIGNER, Jade, SeedSigner, Trezor, Ledger, BitBox02, Passport, Keystone or Coldcard.
- Honey Badger needs three, one of them an inheritance key.
- Buy hardware directly from the vendor to reduce tampering risk, as Nunchuk advises.
Nunchuk fees and limits
- Iron Hand is $120 a year for a 2-of-3 assisted wallet.
- Honey Badger is $480 a year for two 2-of-4 wallets with inheritance planning and spending limits.
- Honey Badger Premier is $2,100 a year for three 3-of-5 wallets with two inheritance keys and multi-person roles.
- Hardware is extra, though subscribers get 15% off Blockstream Jade and Portal.
The free plan covers DIY wallets with community support. Changing the inheritance protocol later means migrating funds to a new wallet, which costs network fees.
Risks to know before using Nunchuk
- Nunchuk says it never custodies funds, so key backups are your responsibility.
- Switching inheritance protocol or timelock type later means creating a new assisted wallet and moving coins.
- The autonomous option requires every hardware key to be Miniscript-compatible, and the flexible option relies on Nunchuk's assisted recovery process.
