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.
No Single Point of Failure
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.
