- Hash-Chained Logs: Links each receipt to the previous one so tampering or skipped steps are detectable.
- Independent Verification: Confirms signatures via a public API or explorer using only a reference ID.
- Drop-In SDK: Installs with pip and wraps existing tools without changing them.
- Framework Auto-Detection: Automatically integrates with LangChain and MCP-based agents.
- Open Source: Released as fetchai/AEVS-sdk for Python 3.10–3.13.
