User reviews

Does not sync transactions

The phone app and the desktop app work independently. Fine if you have a single signature wallet. But the whole reason anyone uses Nunchuk is for the multisig capability. And for that purpose you want transactions that need to be signed to be synced to the other participating members. So the only way is to save a PSBT to a file, email or text the file to another participating user(s). Then the participating user(s) need to import the PSBT file then sign the transaction. Then it can be broadcast. Far too cumbersome.

Personal Node

I’m updating my review of Nunchuk because their support team responded extremely quickly and clearly explained the issue I was experiencing.

I was unable to connect my personal Start9 node on iOS using an SSL onion address on port 50002 with Nunchuk version 2.7.3. Support explained that version 2.7.3 introduced a new SSL certificate requirement and that they are already reverting that change in version 2.7.4.

What impressed me most was how fast Nunchuk support responded and that they were already working on a solution. That kind of communication and responsiveness is very important, especially with a Bitcoin wallet focused on self-custody.

I can currently connect to my node using TCP over Tor on port 50001, and I look forward to testing SSL again once 2.7.4 is released.

Based on my experience with their support and their quick response to the issue, I would recommend Nunchuk. It’s good to see a development team that listens to users and moves quickly to address problems.

Best multisig

Great hot wallet for paying bills and also for teaching friends about multisig.

Bitcoin price.

Nunchuk Bitcoin Wallet earns a solid 9.0 stars for its masterful balance of security and usability in the crypto wallet space.

First impression & onboarding: A lean 15MB download, it skips unnecessary sign-ups, requiring only a seed phrase backup—GDPR-compliant and refreshingly transparent.

Core functionality & daily use: Executes Bitcoin transactions with military-grade multisig, offline signing support, and Lightning Network integration. Syncs reliably across devices; CPU usage stays negligible during operations.

Design & UX: Spartan yet functional; clear navigation without clutter. Dark mode respects battery life, though accessibility options could be expanded.

Privacy & data handling: Impeccable. No third-party tracking, local data storage only, and easy account deletion. Open-source codebase invites scrutiny.

Monetization: Free, with optional donations. No hidden fees or aggressive upsells—a rare ethical stance in finance apps.

Battery, storage, and system impact: Minimal footprint; background processes are strictly limited.

Standout strengths: Unrivaled security features, privacy focus, and developer transparency.

Overall verdict + score: Best-in-class for security-conscious users. A permanent fixture for those prioritizing privacy. Power users and long-term holders, keep it. Casuals might find it overkill. Alternatives: BlueWallet for simplicity.
