Zerion Policy Engine v1.0

Gustack

The create-react-app for secure, autonomous Web3 agents.

Colosseum Frontier Hackathon 2026

The Problem

AI agents are getting wallet access — but who guards the guards?

  • 🚨 No spending limits — A single hallucination can drain a wallet
  • 🔓 No chain restrictions — Agents freely bridge to unaudited chains
  • ⏳ No session expiry — Permissions persist indefinitely, expanding attack surface

$2.1B lost to autonomous agent exploits in 2025 alone.

The Solution

Three policy guardrails. One forkable starter kit. Zero trust assumptions.

🔒

Chain-Lock

Whitelist-only network access. Agent can never bridge to unapproved chains.

💰

Spend-Limit

Hard caps per-transaction and daily maximums. AI auto-corrects violations.

⏱️

Session Expiry

Cryptographic TTL bounds. Permissions auto-revoke after configurable windows.
