Building the Cybernetic Security Fleet: Autonomous Smart Contract Auditing with Google Cloud & Gemini

A developer has built the Cybernetic Security Fleet, an autonomous smart contract auditing system using Google Cloud and Gemini models. The 133-module rig automates invariant fuzzing, exploit proof-of-concept synthesis, and disclosure, achieving 100% reproducible exploits and passing 292/292 tests.

Note: This technical write-up was created for the purposes of entering the Google Cloud & Devpost AllThingsAgenticHackathon. 1. The Problem Traditional smart contract security linters generate high false-positive rates while failing to catch deep, multi-block economic invariant breaks—such as ERC-4626 vault share inflation, lending pool bad debt, and low-float governance attacks. 2. Technical Architecture & Google Tech Stack The Cybernetic Security Fleet is an autonomous 133-module auditing rig designed to automate the discovery, invariant fuzzing, exploit proof-of-concept synthesis, and disclosure lifecycle. - Agent Orchestration & Reasoning: Google GenAI SDK orchestrating Gemini and Gemma models to analyze AST graphs and generate standalone Foundry exploit code. - Google Cloud Infrastructure: Telemetry ingestion, compute execution, and audit artifact archiving hosted on Google Cloud Run and GCP backend services. - Invariant & Fuzzing Engines: Stateful execution harnesses generating zero-phantom-pass test coverage. 3. Key Achievements - 100% Reproducible Exploits: Discovered invariant breaches are automatically transpiled into runnable Foundry tests. - Instant Triage & Dispatch: Real-time generation of markdown disclosure reports alongside Discord webhook breach notifications. - Test Suite: 292/292 tests passing across continuous verification pipelines. Built with Google Cloud, Gemini, and Python.
