Cronos Shield

Intelligent security for AI agents with x402 monetization

Platform combining real-time risk analysis, protected vaults and pay-per-use monetization for AI agents operating directly on blockchain.

Project pitch & demo
01

Overview

Protection and monetization layer for autonomous AI agents operating on blockchain. Evaluates the risk of each operation in real time, holds assets in vaults with configurable rules, and automatically charges per use through the x402 protocol.

02

The problem

Autonomous AI agents need native means to pay for services and protect themselves from attacks in blockchain environments. Today no unified layer offers both functions with transparency and low operational overhead.

03

Approach

Gives AI agents three essential functions: traceability of every decision, protection against abuse through price validation and spending rules, and automated pay-per-use billing. Enables a real economic model for agents that need to transact without constant human supervision.
