Security audit

Gasless stop-loss, limit, TWAP, take-profit & market swaps across 8 EVM chains. Zero fees.

Security checks for vulnerabilities and agentic risk

Overview

This skill is a clearly disclosed DeFi order-building guide that submits signed swap orders to its stated relay, with no hidden code execution or persistence.

Before installing, understand that this skill can help prepare and submit real token swap orders. Review every chain, token, amount, limit, deadline, recipient, allowance, and relay destination before approving or signing, and do not reuse signatures after changing order fields.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The examples explicitly tell users to copy a complete relay payload shape and replace fields, while showing a populated signature field and offering no warning that signatures are bound to exact order parameters and must never be reused or mixed across modified payloads. In a swap-order skill, this can lead users or downstream agents to mishandle signed data, accidentally submit invalid or unintended orders, or leak reusable signing artifacts into logs and automation flows.

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Vague Triggers

Low
Category
Not specified by scanner
Confidence
81% confidence
Finding

This is a manifest file, so vague-trigger review applies. The description 'Use for gasless non-custodial EVM market, limit, TWAP, stop-loss, take-profit, delayed-start swaps' reads like a broad activation instruction but does not specify concrete trigger phrases, scope boundaries, or negative examples, which could lead to overbroad skill matching.
