The BRC-181 standard for Bitcoin SV wallets introduces owner-signed spending limits on AI agents' transaction requests, ensuring autonomous transactions stay within set policies. Each AI agent operates from a separate capped account, preventing unauthorized or excessive spending even if the agent is manipulated. The standard allows owners to set spending budgets, restrict recipients, and revoke access, enhancing security. Its adoption depends on wallet providers implementing the standard, which currently has a private reference implementation.
