Nunchuk Wallet:
Cutting-edge security meets user-centric design
the problems
A multi-signature Bitcoin wallet, or “multisig” for short, is the safest way to own bitcoins. Traditional multisig wallets on the market are difficult to use, often accessible to only the most tech-savvy Bitcoin users.
The complexity of these traditional multisig wallet breeds another problem: how to pass on your bitcoins to your loved ones. The more secure a wallet, the harder it will be for your family to access it after you are gone.
Nunchuk was created to solve exactly these problems. To bring down the barrier of entry to multisig, and to create an easy way for Bitcoiners to pass on their wealth.
The starting point of our design is a multisig wallet. The majority of bitcoins lost has been due to the owners' mismanagement of their own keys, not external factors. Multisig significantly improves on this status quo.
A multisig wallet is both more robust — you can lose one or more keys and still be able to access your funds — and more secure — spending requires more than one key. A multisig wallet is a must when it comes to storing bitcoins for the long term.
Most Bitcoin wallets treat inheritance as an afterthought. By contrast, inheritance planning is an essential element of our design.
Nunchuk pioneers the use of a dedicated inheritance key — separated from the other keys in your wallet. This key is not intended for daily use, and can only be activated on a future date chosen by you. Our design ensures that your wallet remains highly secure day-to-day, while providing an easy mechanism for your Beneficiary to access your bitcoins in the future.
From easy onboarding to assisted recovery, you will be in good hands.
Setting up a multisig wallet has never been easier. Our onboarding wizard will guide you through every step of the way, all directly from your phone.
Sleep easy at night knowing that your wallet and key backups are automatically encrypted and securely stored in the cloud.
Multisig already mitigates the risk of key loss, but fret not if you ever lose your key. Our assisted recovery will make recovering your key a breeze.
A wallet, no matter how secure, is incomplete without an inheritance plan. Our innovative solution makes it easy to pass on your bitcoins without compromising on security.
If you ever need more help, rest assured that you'll be able to talk to one of our experts. All accessible directly within the app using our built-in messenger.
Nunchuk is a lot more than just multisig and is packed with an expanding list of powerful features. Here are a few of them.
Lock down your wallet if you face an imminent threat, or simply need to go off-the-grid for a while.
Get granular security control by configuring how the platform key behaves.
A spending limit restricts the platform key to only co-sign transactions that don't exceed the spending limit for a given period. Use one of your hardware keys when spending small amounts, and require two for large amounts.
A co-signing delay gives you time to detect errors or unauthorized access before a transaction is broadcast.
Nunchuk is proud to be the first Bitcoin wallet to offer scheduled payments. Schedule transactions up to a year in advance.
We go out of our way to ensure that you have the utmost privacy.
Sign in using your private key, communicate via encrypted messaging, or set up an inheritance plan that does not rely on proofs of identity.
Nunchuk makes it super easy to pair your wallet with a personal full node, so that you can verify your own transactions on the blockchain.
