Nunchuk

Nunchuk is a multi-signature, or multisig, cryptocurrency wallet. The multisig technology is intended to solve the problem of decentralized ownership and make cryptocurrency custody more resistant to accidents and attacks. The wallet offers a multi-user feature that allows users to co-manage cryptocurrency with trusted people, reducing the burden of key management. Further, Nunchuk offers users control of their data and communication.

Further, the wallet is a self-custodial cryptocurrency wallet, meaning it does not collect user identification information other than email addresses, and it does not hold users' private keys—meaning users maintain control over their assets, rather than having those assets in the custody of a financial third party.

The Nunchuk wallet offers multi-device sync, allowing users to manage their cryptocurrency from multiple devices. Air-gapped signing allows users to keep their keys disconnected from the internet with an air-gapped feature. Nunchuk enables users to validate their own transactions through a personal blockchain node, and users can pair their wallet with that node.

Further, the Nunchuk wallet develops native applications for increased security and control from Nunchuk and to reduce the attack surface of the cryptocurrency wallet. Nunchuck wallet does not require users to have hardware keys, but allows them to use Nunchuk's software keys. And it offers extensibility, with core code designed to be extensible.
