Launched in 2020, the app provides customers a feature-rich toolkit to arrange high-security bitcoin wallets, with little competitors on the cell app market, as most different cell wallets don’t assist multi-signature performance in any respect.
Most wallets require a single personal key to signal a sound Bitcoin transaction.

Nunchuk instructed Bitcoin Journal they assist safe over a billion {dollars} value of bitcoin right now, “it’s our (paid) assisted companies which have helped customers safe +$1B in BTC to date.”, however that was not at all times the case. Born out of Bitcoin idealism within the thick of the COVID pandemic, Nunchuk was constructed to facilitate superior safety wallets that use multi-signature within the protection of self-custody. In 2022, as a younger start-up, these beliefs have been put to the take a look at, as activists of the Canadian Freedom Convoy Protests determined to make use of Nunchuk to safe bitcoins donated to the protest towards COVID repression.
The turmoil noticed over one million {dollars} value of Bitcoin donated to Honk Honk Hodl, a bunch of respected activists within the nation, to assist fund the prices of Truckers who have been gathering in Ottawa.

Over 20 bitcoins have been obtained right into a Nunchuk multi-signature pockets below the banner of Honk Honk Hodl. Nunchuk multi-sig was chosen to mitigate the danger of placing all that cash within the fingers of only one individual.
Hugo Nguyen, founding father of Nunchuk, instructed Bitcoin Journal that the Honk Honk Hodl pockets obtained so many particular person donations that it really broke the pockets. The app was not designed to signal transactions with so many bitcoin inputs, and the start-up needed to push an replace to let the activists simply transfer their funds.
The protests have been so efficient and gained such a optimistic reception internationally that Trudeau’s authorities panicked and invoked the Emergencies Act, a uncommon use of federal powers, which he used to attempt to shut down all sources of funding coming to the protesters, in an effort to scare them off the capital. This included 10 million {dollars} in donations from Canadians to a GoFundMe marketing campaign, which have been in the end returned to contributors after the fee processor confronted authorized motion from the Canadian authorities.
When it got here to the bitcoin donations, the digital foreign money’s alleged censorship resistance was put to the take a look at. Canada despatched a Mareva injunction to Nunchuk Inc., demanding the corporate freeze person funds and disclose person knowledge to the federal government. Nunchuk, as a privacy-oriented, non-custodial pockets, had no energy to conform. Nunchuk was simply two months outdated on the time, a self-funded startup. This was their response:
“Pricey Ontario Superior Court docket of Justice,
