Question 1

What is AEVS?

Accepted Answer

AEVS (Agent Execution Verification System) is a drop-in SDK that produces tamper-evident proof of execution for AI agent actions. It sits between an agent and its tools and captures every invocation — tool name, inputs, output, timing, and errors — then seals each record as an ECDSA (P-256) signed receipt linked to the previous one in a hash chain, so any alteration or skipped step is detectable. Receipts can be verified independently through a public API or explorer using a reference ID, without access to the original codebase. AEVS auto-detects frameworks like LangChain and MCP, installs via pip, and is open source under fetchai/AEVS-sdk, currently in beta.

Question 2

How much does AEVS cost?

Accepted Answer

AEVS is completely free to use.

Question 3

Who developed AEVS?

Accepted Answer

AEVS was developed by Fetch.ai. Fetch.ai is a platform company building infrastructure to connect services, APIs and autonomous agents. Its stack includes uAgents (agent SDK), the AI Engine (agent orchestration and human input bridge), the Fetch Network (decentralized trust and traceability) and platforms for deploying and discovering agents.

Question 4

What are the key features of AEVS?

Accepted Answer

AEVS offers the following key features: 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..

Question 5

What is AEVS?

Accepted Answer

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

Question 6

How does AEVS work?

Accepted Answer

AEVS works by combining 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. to help users with 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., Third-Party Verification: Let external parties confirm an action occurred without sharing source code..
