Who this is for: You’ve deployed — or your client has deployed — an AI agent that can move money, sign transactions, or commit an organization. When that agent acts, no court will hold it responsible. A human will be: the founder, GP, or officer who turned it on. FAF is the legal wrapper that bounds that liability; the enforcement mechanics that make the wrapper binding live in OEE. The rest of this page explains how the two connect.
AI agents are not legal entities. They cannot sign term sheets, act as fiduciaries, or be held liable in a court of law. Handing an AI execution authority over a treasury without a legal wrapper is an unquantifiable liability for human operators. The Fiduciary Agent Framework (FAF) is the legal governance layer of the Sigil Open Framework — the counterpart to OEE’s technical enforcement. FAF does not attempt to grant an AI legal personhood. Instead, it creates a legal governance wrapper around OEE’s enforcement infrastructure:
  1. The Agent as Property: Utilizing ERC-6551 (Token Bound Accounts), the AI agent exists on-chain as a tokenized asset (an NFT).
  2. The Legal Anchor: That NFT is legally owned by a recognized, real-world entity — an LLC, DAO LLC, or human General Partner.
  3. Bounded Liability: Because OEE mathematically guarantees the agent cannot break its hard-coded policy, human partners can safely wrap that code in a legal entity without assuming infinite risk.
OEE enforcement closes the execution gap. FAF closes the legal gap. View the Repository: github.com/Sigil-Core/faf
