About this app

Nunchuk is the safest and most advanced self-custody solution for your bitcoin. Nunchuk is your bitcoin’s best defense against theft, fraud, loss of private keys or forgotten passwords. 

Compared with normal Bitcoin wallets, Nunchuk’s multi-user multisig wallet gives you two extra levels of protection. First, the use of multisig technology means that losing any one key will not compromise your bitcoin. Second, our multi-user features allow you to co-manage your bitcoin with your trusted ones, effectively reducing the burden of key management. Millions of bitcoin have been lost forever due to individuals mishandling their own keys. Crucially, Nunchuk helps protect you from yourself.

Besides security, strong privacy is our other core design principle. We believe that privacy is non-negotiable and must be built-in from day one. Our obsession with privacy ensures that you have total control of your wallets and all your data.

Highlights:

NO SINGLE POINTS OF FAILURE
A Nunchuk multisig wallet protects your bitcoin with multiple keys: at least two keys are required for spending. The loss of any one key will not compromise your funds.

EXTRA SECURITY WITH GROUP CUSTODY
Nunchuk boosts your bitcoin defense through collaborative custody. Co-manage your bitcoin with your trusted ones. Communicate and transact. All in one place.

TOTAL PRIVACY
The more people involved, the higher the risk of data leaks. Nunchuk’s end-to-end encryption (E2EE) ensures that all your communication and transactions stay within your group. No one else can know. Not even Nunchuk.

FULL DATA CONTROL
All data is stored on your local devices. With the provided backup, your wallet could be safely recovered anytime, anywhere. You have complete control over your keys, your funds, your data.

HARDWARE KEY COMPATIBILITY
Nunchuk supports all major hardware keys, including but not limited to: Trezor, COLDCARD, Keystone, Ledger, and BitBox02.

SOFTWARE KEY
No hardware keys? No problem. Just use Nunchuk software keys.

ADDITIONAL FEATURES
We go the extra mile to build the safest and most seamless Bitcoin wallet:
* Available on all major platforms: Android, iOS, Windows, Mac, Linux.
* Multi-device sync: Nunchuk is the only Bitcoin wallet that allows you to manage your bitcoin securely from multiple devices.
* Native applications: We take no shortcuts when it comes to security. Native applications like Nunchuk take longer to develop but are significantly more secure than non-native ones because they have a smaller attack surface.
* Air-gapped signing: Keep your keys completely disconnected from the Internet with air-gapped mode.
* Extensibility: Want advanced smart contract capabilities? Nunchuk reuses Bitcoin Core code directly and is designed to be easily extensible. Reach out if you have a feature request!
* Open-source: Nunchuk core library is open-source.
* Personal blockchain server: Validate your own transactions. Nunchuk makes it super easy to pair your wallet with a personal full node, be it Electrum or Bitcoin Core (optionally over Tor).

I came to need to use Bitcoin to make a purchase. When the need arose there was only one option for me and that was the company that told the authoritarians where they could go. I'm not gonna lie, I just downloaded it and will be using it within the next week or so. I'll update the review after I do BUT based on reviews here and what I searched and read on line before finalizing the decision to use their wallet I expect there to be NO issues.

I made a key, then a wallet. When restored the wallet, its a different key in the wallet so i cant withdraw my funds! 0.03 btc stuck with no chance of getting it. I followed the steps, and now my bitcoins are stuck. It is not okay.

Asked for an email address on the start screen. I expected a Decentralized solution. On the description it was told all my data stays on the device. This doesn't match with asking an email address, because by creating a remote account at least my email address isn't local anymore. Hope to see just a solution with providing key/seed.

Hi, Nunchuk allows a group of people to co-manage their bitcoin. For inter-personal (encrypted) messaging to work & to have a way for users to 2FA, we use email as ID. We chose email because it is much more anonymous compared to say, Signal phone numbers. There is also a stand-alone Guest mode on desktop, which doesn’t require email signup at all.
