nunchuk_io

Most agentic wallets give the agent a standalone wallet or delegated signer.
Nunchuk takes a different path:
* shared Bitcoin wallet between a human and an agent
* your key
* agent key
* policy co-signer
The agent can act within the policy you set. Above the limit, your signature is required.
Funding a wallet and authorizing an agent are not the same decision.
The wallet can receive funds without automatically increasing what the agent can spend. Receiving is a normal wallet operation. Spending authority is configured separately through Platform key policies — limits, delays, approval flows.
What ships today:
* local key generation + encrypted key storage
* group wallets (m-of-n multisig); Miniscript support is WIP
* sandboxes, invites, joins, finalize
* fresh receive addresses
* create / sign / broadcast txs
* descriptor/BSMS export + recovery
* platform-key policies + dummy-tx approvals
We're publishing two MIT-licensed repos:
1. nunchuk-io/nunchuk-cli — the CLI
2. nunchuk-io/agent-skills — a skill pack that teaches AI agents how to use the CLI
Agent Skills currently covers:
* setup, login, network, config
* wallet creation
* invitations
* Platform key policies
* wallet management
* tx create / sign / inspect / list / broadcast
You install the skills pack and CLI separately.
What builders can layer on top:
* human+agent wallets
* multi-agent wallets
* bill pay agents
* treasury / UTXO management
* privacy-aware spend flows
* agent-to-agent payment flows
Both repos are MIT. You'll need a Nunchuk API key to use the CLI — get one at developer.nunchuk.io.
CLI: github.com/nunchuk-io/nunchuk-cli
Skills: github.com/nunchuk-io/agent-skills
AI should help with financial execution — not get unconstrained control over your money.
Automate what you want. Keep human approval where it matters. Build on Bitcoin.

"When the Canadian dollar becomes worthless, we will be here to serve you, too."
That was our closing reply to the Ontario Superior Court of Justice in 2022, when they ordered us to freeze and disclose information about the bitcoin involved in the Freedom Convoy protest.
The story of how that email came about has never been told. Today, we’re sharing that story, and how that event forged our DNA & mission.
***
February 2022. The Freedom Convoy protest was paralyzing Ottawa. Two years of lockdowns and mandates had created incredible social tension.
On Feb 14, Justin Trudeau invoked the Emergencies Act for the first time in Canadian history. It was designed for wars or terrorism; it was now being used against protesters.
Protesters’ bank accounts were frozen without due process. GoFundMe seized $10M in donations at the government’s request. The RCMP demanded that financial firms blacklist Bitcoin addresses.
The Ontario Securities Commission flagged tweets by Coinbase CEO Brian Armstrong and Kraken CEO Jesse Powell criticizing the use of the Emergencies Act to law enforcement. Balaji Srinivasan questioned whether Canada was still a “democracy”. Police began mobilizing in Canada’s capital.
The authorities seemed willing to use everything, even extraordinary measures, to quash the protest.
Many Bitcoin companies backed away, despite having millions in funding.
Jesse Powell, having previously donated one bitcoin to the protest, warned users that Kraken “cannot protect you” from the Canadian government. Elon Musk, who voiced support for the protesters, tweeted “I wish I could help. At this point, it seems that voting at the next election is the remedy.” Even powerful CEOs seemed powerless in the situation.
Then, we received the Mareva injunction.
Nunchuk, a tiny startup still in its infancy, was ordered to freeze assets and disclose information. We are self-custodial and technically unable to comply. But the threat was serious.
The pressure was immense. We had no idea how far the Canadian government was willing to go. And judging by what they had done: very far.
Concerned about the risks to their families, two members of our team decided to quit.
It was an existential crisis.
To complicate the situation, my own personal life was in upheaval.
Around the time the Emergencies Act was invoked, I learned that I would soon become a father.
I went from pure joy to total distress within a week. I thought about the world my child was going to grow up in.
I thought about why I started a Bitcoin company in the first place.
If Bitcoin couldn’t matter in a situation where people needed it most, what good is it? How is it any different from the corrupt, permissioned financial system we grew up with? The one that brought the world to its knees in the Great Financial Crisis, along with many other social woes that we’ve only begun to understand since the shift in 1971? What’s the point of it all?
What will I tell my son about what happened in February 2022?
Then I sat down and wrote the reply.
That email became our North Star. It clarified our mission: to build tools that maximize individual financial freedom and privacy, minimizing reliance on any third party.
"Trusted third parties are security holes", as the great Nick Szabo once said.
This event taught us that true sovereignty requires technologies designed to withstand pressure. Not just from governments, but from time itself.
If we are to secure wealth for generations, our solutions must eliminate ALL single points of failure. They must be designed to outlive us.
Today we announce the next major step in that mission: the realization of our commitment to trust-minimized generational security.
Today we introduce the first assisted Bitcoin inheritance solution, designed to outlive the company that created it. It’s the culmination of all the work we’ve done since that fateful day in 2022. You can read about it here:

Nunchuk apps are NOT vulnerable to the recent NPM security exploit.
Our apps are fully native, with no Javascript or NPM dependencies. This was a conscious decision to reduce our supply chain to the bare minimum.
We believe that for mission-critical software like a Bitcoin wallet, avoiding Javascript and the web-based ecosystems is a fundamental security principle.

Bitcoin will dwarf the internet's economic impact.
The internet moves information. Bitcoin moves value (info with 1,000× weight).
Today we're shipping the UX to make that real: Miniscript + E2EE group wallets.
These tools combined will make programmable Bitcoin for everyone.
https://blossom.primal.net/4cb897919731f1fe7ad90cef80fb1964524eeef9e77d6d7b032c9f03cac8bf38.png
Bitcoin has always supported spending rules (multisig, time delays), but they were complex and risky to implement.
Miniscript structures these rules like Lego blocks, making advanced custody safe, simple, and verifiable.
We didn't just add a few pre-baked scripts.
Nunchuk now supports *generalized* Miniscript. You can create any policy supported under standard Bitcoin rules.
Use our friendly templates, or craft custom spending rules if you're advanced.
https://blossom.primal.net/d44e020faf66d7bd9a884ca4e21b2c8c3cbe60d31d73afd908e2d35c16bacb38.png
Complex policies involving multiple parties require coordination. Doing this over insecure channels (email, messengers) is a major security risk.
Nunchuk solves this. Our E2EE Group Wallets now support Miniscript out of the box.
The entire setup is encrypted, with built-in chat for secure coordination.
https://blossom.primal.net/6d23c265366999d99cb37a8d7053545c697024207f629766836da5c1af0d6f88.png
This combination lets you build wallets that adapt to real life needs, such as:
🧊 Timelocked inheritance plan
🏛️ Business treasuries with layered approvals & fallbacks
🤝 Non-custodial escrow for OTC trades
👻 Private multi-party wallets that look like single-sig on-chain
https://blossom.primal.net/81544cae4356a9c0c6c0eabb0bb1e77ce5e2610b9077b25daa703bb66a5c93cd.png
You have options.
Prefer simple and widely compatible? Use Native SegWit.
Want advanced privacy and efficiency?
• Taproot hides unused spending branches.
• MuSig2 aggregates multiple signers into one signature (key path or script path).
The choice is yours.
We support major hardware vendors today:
Native SegWit Miniscript: COLDCARD, Tapsigner, Blockstream Jade, Ledger, Specter DIY
Taproot Miniscript: COLDCARD, Ledger, Specter DIY
MuSig2: Software keys only (for now).
More coming as vendors ship support.
Zooming out: These tools (verifiable policies, secure collaboration, advanced scripting) are the primitives of a new financial system.
Fair, open, and anchored to sound money.

Agreed. Bitcoind was never designed to be a server. And RPC over HTTP is insecure.
That’s why we have things like the Electrum protocol, which was designed to be a proper backend server for syncing. (You can design a different protocol, but that’s another story).

Hey Vitor, just to let you know you can connect to your own (Electrum) node in several mobile wallets, including Nunchuk. Tor is possible too.

That's a valid point. Finding the right balance in our messaging is a constant challenge, and we take the responsibility to avoid creating that anxiety very seriously.
But for us, putting up a paywall isn't the answer, because 1Password, as great as they are, don’t solve the same existential threat we're focused on.
Bitcoin self-custody is already seen as "hard" by most people, and the massive push towards ETFs and custodial services makes it worse every day. Our core mission is to fight that trend. From day one.
What use are our services if the foundation itself gets destroyed? If 90% of Bitcoin ends up with custodians in 20 years, the project will have failed, and everything we've been building (which, btw, include networks like Nostr) will have been for nothing.
To win this battle, the best and most secure tools for self-custody must be free and accessible to the largest number of people possible. That's why the Nunchuk base app will always be free. It’s non-negotiable for us.

How do you build a truly independent, self-sustaining Bitcoin company?
Here’s our philosophy and North Star:
* Build best-in-class self-custody tools. Make them free.
* Offer premium services for advanced needs.
* Use revenue from (2) to fund (1).
This keeps us independent and 100% aligned with our users and Bitcoin ethos. The full context from a recent discussion is below.

No worries at all, and thanks for the clarification. Finding the right way to present our paid services without being intrusive is a tough balance. It’s something we always try to improve on. Appreciate the feedback.
The idea of a paid base app is interesting, but we're committed to keeping the core tools free for all, for reason we highlighted above: we need as many people as possible to have access to safe and easy to use self-custody tools. If the base app is paid, we wouldn’t be able to achieve that goal.

2025-08-07 15:24:01 UTC

- reply

Respectfully, the claim that we 'only exist to get users to join premium bullshit services' is the opposite of reality.
Since day one, we have been pouring huge resources into building and maintaining a professional-grade Bitcoin wallet and offer it for free. We led the way with standards like BIP129, advanced coin control and were first with features like encrypted group wallet and Taproot/MuSig2 support. We do this because we believe that if the majority of Bitcoin is not in self-custody, the project will fail. In fact, the vast majority of our users are free users, and we dedicate about 80% of our development efforts each year to free features.
Calling our premium services 'bullshit' is a mischaracterization. They solve critical, high-stakes problems for people who need them, and the revenue from those services is precisely what allows us to keep the core wallet free, private, and independent.
The alternative is VC funding, ads, or tracking users. We're committed to building a sustainable business on a Bitcoin standard, and we believe our model is the right one for our users and for Bitcoin itself.

Correct, Tapsigner doesn’t use BIP39 seed phrases, but raw master private key (XPRV), which is a level lower than seed phrase (a seed phrase is an abstraction over XPRV).

New mobile release!
• Taproot multisig wallets: manual and automatic fee selection
• Show saved address labels in transaction details
• Option to rebroadcast rejected transactions
• Update default signet server
• Add guest wallets notice
• Assisted wallets: option to manually save BSMS in Setup Wizard
• Bug fixes and improvements
Taproot fee selection: what’s that about?
Taproot lets one wallet hide many spend paths.
Different path → different weight on-chain → different fee required.
So we added two ways to handle it:
• Manual: see every path and its fee. Tap the one you want.
•Automatic: if cheap-vs-costly is ≤ 10 % or $0.20, we default to the pricier path. Tweak the thresholds or turn them off any time.
As Bitcoin smart contracts get more complex and the subsidy era fades, fee variability will keep growing, both within a single path and across multiple paths, even before you factor in fee-bumping tools like RBF or CPFP.
We’re building a solution that’s easy to use and puts you in control.

Yes, for cold storage you might not want to only use Tapsigners (although, even a Tapsigner-only multisig would still be better than something like Bitkey, which is a closed system). As long as you have at least one hardware in your multisig quorum that has a display and can verify transactions independently, it’s a solid setup.

We also have a Decoy Wallet feature that gives you plausible deniability. Check it out here:

2025-05-21 16:38:58 UTC

- reply

You can pair a hardware signing device with Nunchuk that does have a display (like a Coldcard or Blockstream Jade), and verify the details of the transaction before signing. You can also pair multiple hardware with Nunchukm and create a multisig wallet, which offers superior security and robustness compared to a singlesig wallet.
In the above setup, Nunchuk only acts as a watch-only wallet coordinator. So yes, 100% Nunchuk can be used for cold storage. And many of our users have done so.

KYC is a disaster waiting to happen.
If data leaks can happen to Coinbase, it can happen to anyone.
Related: never use a Bitcoin inheritance service that requires KYC.
You’re not just endangering yourself — you’re putting your family at risk too.
They’re even less equipped than you to defend against attackers.
Nunchuk’s inheritance protocol is non-KYC. That’s by design.

2) Updated fee estimates
Our app now shows fee estimates for both key path and script path, so you’ll know exactly what each transaction costs—or how much to bump via RBF. https://m.primal.net/QJkX.png

1) Disable key path spending
https://m.primal.net/QJkW.png
By default, key path spends reveal a public key on-chain—great for privacy and lower fees. Theoretically, future quantum computers could target these keys (though that’s still many years away). If you prefer extra caution, you can now stay quantum-resistant by disabling key path spends.

Taproot multisig wallets are a game-changer for superior privacy and lower fees.
If you’re new to Taproot or need a refresher, check out our previous announcement and blog post: https://nunchuk.io/blog/taproot-multisig

TARIFFS ARE INFLATIONARY. STACK HARDER.
With the US–China trade war heating up, there’s no better time to double down on self-custody.
Here’s what’s new in Nunchuk’s latest release:
• Option to disable key path spending in Taproot multisig wallets
• Fee estimates for key path vs. script path
• Export transaction history to CSV
• Bug fixes & improvements for group wallets

We couldn’t reproduce the issue. Were able to successfully add a Coldcard Q key via QR. Are you sure you scan the correct QR?

They are completely different wallets. NativeSegwit and Taproot wallets are defined differently. They don't even use the same derivation path for the XPUBs. Sounds like Stack Wallet implement it in a non-standard way.
BIP84 describes a NativeSegwit singlesig wallet.
BIP86 describes a Taproot singlesig wallet.

They are completely different wallets. Without the seed phrase on testnet4, we can’t reproduce the issue.

Careful, we don’t have a Telegram group!

FYI, our group wallet + chat is not proprietary.
It is open source and built on BIP129 (which we co-authored). More information in this blog: https://nunchuk.io/blog/group-wallet

It does work with Start9 over Tor. You'd need a Tor proxy (Orbot or Tailscale) on your phone.

The ByBit hack essentially boils down to three things:
• Users failing to verify all transaction/contract details
• Users relying on a browser-based wallet that’s easy to spoof
• Ethereum contracts being fundamentally complex and mutable (“upgradable”)
Stick to Bitcoin and natively written wallets for serious money.
