I built an AI agent that charges $0.001 to protect other AI agents — and every blocked attack is permanently recorded onchain. Built solo in 5 days from Burkina Faso.

An AI agent named ArcWarden was developed to secure autonomous AI agents managing USDC wallets on blockchain by charging $0.001 per transaction evaluation. It uses onchain recording of blocked attacks via a Vyper smart contract and operates autonomously with multiple security layers, achieving 99.7% cost savings compared to traditional solutions.
