WETH Guardian

As Large Language Models (LLMs) and autonomous AI copilots evolve into active economic agents managing on-chain assets, they encounter a critical vulnerability: Direct AI or human execution on EVM chains without pre-broadcast simulation and multi-hop threat graph intelligence leads to catastrophic wallet drains.

WETH Guardian ASP transforms raw blockchain infrastructure into an Agentic Security Service Provider (ASP) runtime specifically engineered for the OKX AI ecosystem. It bridges zero-dependency local semantic intent routing, Neo4j AuraDB multi-hop threat graph traversal, and deterministic EVM eth_call state simulation to deliver instant guardrails [CRITICAL_RISK], [MODERATE_RISK], [VERIFIED_SAFE]) with < 45ms latency.

### Core Features:

1. Zero-Key Intent Routing: Natural language AI copilot router that classifies user intent without external LLM API latency.

2. Neo4j Threat Graph Traversal: Evaluates multi-hop graph connectivity across known drainers, phishing clusters, and proxy delegation chains.

3. Deterministic EVM Simulation: Intercepts hex calldata 0x095ea...), simulates state transition traces against live RPC nodes, and estimates gas before signing.

4. Institutional Terminal UI: A monochromatic Next.js dashboard built for institutional operators to review AI-generated security metrics.

During the OKX.AI Genesis Hackathon, we built the entire WETH Guardian platform from scratch:

- Engineered the Agentic Security Service Provider (ASP) backend using Fastify.

- Implemented the Zero-Key Local Semantic Intent Router for <2ms natural language intent classification.

- Built the Neo4j Multi-hop Threat Graph Traversal system for evaluating risk.

- Integrated deterministic EVM simulations to parse and simulate hex calldata before broadcasting.

- Designed and developed the monochromatic Next.js Terminal UI Security Dashboard.

- Wrote a comprehensive test suite (37 passing tests) across 13 test files to ensure infrastructure integrity.
