Nunchuk released two open source repositories that aim to reshape how AI agents interacted with Bitcoin wallets. The model introduced limits the agent’s control, while maintaining human oversight.
It is important to note that the word “you” means “you”. release Nunchuk CLI is a command-line tool for managing Bitcoin wallets. It also includes a companion app. “Agent Skills” The repository is designed to assist AI systems in operating the CLI through common workflows. Nunchuk explained that the tools, which are both licensed under MIT licenses, target developers creating automated financial systems based on Bitcoin.
This core concept challenges an emerging trend in AI wallet designs. Instead of granting agents full control Nunchuk offers a model of shared custody whereby agents are bound by strict policies and have access to funds. The final decision is made by the human user over any transactions above predefined thresholds.
Wallets can be configured to work as multiple-key group wallets. To authorize transactions, a user key, an agency key and a co-signer of the policy work in conjunction. The agent is able to initiate certain actions, such as inviting participants or creating transactions. But the spending authority of an agent remains limited due to rules established at the policy-level.

The policies set limits, such as the daily limit of spending, requirements for approval, and delays in signing. Transactions falling within parameters are allowed to proceed with no intervention. Larger or more sensitive actions, however, require user approval.
Nunchuk is a device that separates automation from custody. The wallet controls ownership of money, while the policy layer defines what agents can do. The distinction between the wallet structure and policy layers ensures that agents do not gain more authority by funding their wallet.
CLI offers a variety of functionality, such as key generation and wallet creation. It also supports transaction workflows and policy configuration. The CLI allows users to export backups, wallet descriptors in standard formats. This facilitates portability outside of the Nunchuk eco-system.
It is an interface layer that AI systems use. This repository contains predefined instructions and prompts to guide agents in tasks, such as managing wallets, setting up participants and performing transactions. The need for integrations is reduced and there are fewer barriers to entry. developers experimenting with Bitcoin-based automation.
Nunchuk positions its dual-repository solution as an answer to two separate challenges: usability and execution. The CLI is the execution layer that’s tied into the Nunchuk API. Meanwhile, the Skills layer looks at how AI systems interact with the infrastructure.
This release is part of a larger effort to establish safe AI design patterns in financial contexts. Nunchuk’s goal is to automate practical tasks without taking on full custody risk by enforcing bound authority.
Some examples of possible use cases are shared wallets between humans and agents, automated payment systems for bills, Treasury management tools, or multi-agent co-ordination. Although these applications are in their early stages, they provide a model for controlled experimentation.
Control becomes a central issue as AI systems have access to more financial instruments. Nunchuk’s method suggests that a better way forward is to structure authority rather than restrict capability.
