Open-source SDK that creates tamper-evident, cryptographically signed receipts for every tool call an AI agent makes.

Signed Receipts: Records every tool call and seals it with an ECDSA P-256 signature backed by KMS.
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.

Agent Auditing: Keep a verifiable record of exactly what an agent did and when.
High-Stakes Actions: Prove execution of sensitive operations such as payments or refunds.
Compliance Evidence: Provide tamper-evident logs for regulated or accountable workflows.
Debugging Agents: Inspect tool inputs, outputs, timing, and errors for each call.
