Security audit

Market Tick

Security checks across malware telemetry and agentic risk

Overview

This is a simple paid market-data lookup skill that uses an EVM wallet for x402 payments, with no hidden code or unrelated behavior found.

Install only if you are comfortable letting an agent use a wallet private key to pay for market-data calls. Use a dedicated low-balance wallet, keep the private key out of chat and logs, and confirm expected call volume because repeated automatic calls can spend USDC.

Missing User Warnings

Medium
Confidence
97% confidence
Finding
The skill instructs the agent to make an x402-authenticated request using an EVM private key and states that payment authorization happens automatically, but it does not present a prominent user-facing warning that using the skill can spend wallet funds. Because the skill is tied to a blockchain wallet and per-call charges, a user or calling agent may invoke it without understanding that real monetary authorization and on-chain payment behavior are involved.
