Nunchuk has introduced a new set of open-source tools designed to enable artificial intelligence agents to manage Bitcoin wallets within strictly defined limits. The initiative reflects a growing effort to combine automation with robust security practices in cryptocurrency custody. By implementing a concept described as bounded authority, the tools ensure that AI agents can execute financial tasks without gaining unrestricted control over wallet assets.
The release builds on Nunchuk’s established reputation as a flexible Bitcoin wallet provider known for supporting multisignature configurations and collaborative custody models. These capabilities have historically allowed individuals and groups to manage Bitcoin holdings securely, whether for personal use or shared financial management.
AI Integration Without Compromising Control
The newly launched Agent Skills repository introduces command-line interface capabilities that allow AI systems to perform tasks such as wallet creation, participant invitations, and policy enforcement. This approach enables automation of wallet operations while maintaining human oversight for critical decisions.
Developers involved in the initiative indicated that traditional AI wallet models often rely on granting agents direct access to funds with minimal safeguards. In contrast, Nunchuk’s framework prioritizes shared control, where AI assists with execution but does not hold ultimate authority over assets. This model ensures that ownership and key control remain firmly with the user, reducing the risk of misuse or unintended transactions.
The system operates through a structure that includes a user key, an agent key, and a policy co-signer within a shared Bitcoin wallet. The AI agent can perform tasks such as authentication, network selection, wallet setup, and participant onboarding. However, any action exceeding predefined policy limits requires explicit user approval, reinforcing a layered security approach.
Two-Tier Architecture Enhances Security
Nunchuk’s solution separates wallet custody from automation policies, creating a dual-layer framework. At the custody level, users maintain control through a group wallet structure. At the automation level, policy-driven co-signing determines which transactions can be executed automatically and which require additional authorization.
This separation is particularly significant in distinguishing between receiving and spending funds. While receiving Bitcoin remains a standard wallet function, spending permissions are governed independently through configurable policies such as transaction limits, approval workflows, and time delays. As a result, funding a wallet does not automatically expand an AI agent’s authority to spend those funds.
AI agents shouldn't get the full key to your kingdom.
Today we're releasing Nunchuk CLI: create a shared Bitcoin wallet with your agent, give it a spending budget, and keep the final say.

Comprehensive Toolset for Developers
The command-line interface provides a wide range of functionalities, including authentication, key generation, wallet creation, transaction management, and policy configuration. It also supports exporting wallet descriptors and backup files, ensuring portability and recovery options for users.
Complementing this, the Agent Skills repository offers prebuilt workflows that guide AI systems in executing tasks across the entire wallet lifecycle. These include setup, administration, policy management, and transaction handling. By separating the execution layer from the AI interface, Nunchuk allows developers to maintain a streamlined core system while enabling continuous improvements to AI-driven capabilities.
Expanding Possibilities for AI-Driven Finance
The introduction of bounded authority opens the door to several advanced use cases in cryptocurrency management. Potential applications include hybrid human-AI wallets, multi-agent financial systems, automated bill payments, treasury management, and privacy-focused transaction flows. Additionally, the framework could support agent-to-agent payment systems, further expanding the role of AI in decentralized finance.
Although these applications are still in exploratory stages, the underlying infrastructure provides a foundation for innovation without compromising security. The tools are also compatible with advanced scripting mechanisms such as Miniscript, allowing for more sophisticated wallet configurations and approval processes over time.
Open-Source Approach Promotes Transparency
Nunchuk emphasized portability and transparency by making the tools open source and supporting standard backup formats. This ensures that users are not locked into proprietary systems and can migrate or recover their wallets as needed.
To utilize the tools, developers are required to obtain an API key and follow a structured setup process that includes installing the command-line interface, configuring the network, generating keys, and defining policies. Once configured, users can begin transacting while maintaining strict oversight of AI-driven actions.
Strengthening the Future of Secure Automation
The release highlights a broader shift toward integrating AI into financial systems in a controlled and secure manner. By enabling AI agents to perform meaningful tasks within clearly defined boundaries, Nunchuk is contributing to a more balanced approach to automation in cryptocurrency management. The model underscores the importance of preserving human authority while leveraging AI to improve efficiency and scalability in digital asset operations.
