Polymarket Sniper Bot (Standalone)

• Outcome: Review
• Latest audit: May 29, 2026 · 9:28 PM UTC
• Version: 1.0.1

Overview

This is a real-money autonomous trading bot whose financial authority is disclosed, but its live-trading safeguards, credential handling, install flow, and fallback trading logic need careful review before use.

Install only after reviewing the code and running it in simulation first. Use a burner wallet with limited funds, avoid storing private keys in plaintext config files, do not expose the dashboard publicly, pin dependencies inside a virtual environment, verify any license server is trusted HTTPS, and add an explicit live-trading opt-in with spend limits and a stop procedure before enabling the scheduled scans.

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• Taint Tracking: Direct Taint Flow, Variable-Mediated Taint Flow, Credential Exfiltration Chain
• MCP Tool Poisoning: Hidden Instructions, Unicode Deception, Parameter Description Injection
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands

if not PRO_LICENSE_KEY:

Intent-Code Divergence

Medium

• Confidence: 93% confidence
• Finding: When real market data is unavailable, the code fabricates a positive 3% momentum signal that can trigger trading logic. In a trading agent with live execution capability, this is dangerous because failures or API disruption can cause false buy decisions and real financial loss without any genuine market signal.

Context-Inappropriate Capability

Medium

• Confidence: 95% confidence
• Finding: The script uses `pip3 install ... --break-system-packages`, which intentionally bypasses Python environment protections and modifies the system-managed interpreter environment. This can corrupt OS-managed Python packages, create dependency conflicts, and increase supply-chain risk if unpinned or compromised dependencies are installed globally. In the context of an autonomous trading bot that may be deployed on a host with wallet keys and live execution capability, destabilizing the system Python environment or pulling unsafe packages is more dangerous than in a disposable development container.

Missing User Warnings

Medium

• Confidence: 88% confidence
• Finding: The deployment guide instructs users to place a raw wallet private key directly into config.yaml and does not provide explicit guidance on secret storage, file permissions, or safer alternatives such as environment variables or a secrets manager. In the context of an autonomous live-trading bot that controls real funds, this increases the likelihood of accidental key exposure through source control, backups, logs, screenshots, or multi-user server access.

Missing User Warnings

Medium

• Confidence: 90% confidence
• Finding: The skill promotes autonomous live trading and a one-command bootstrap flow without prominent warnings that it can place real trades and affect funds. In a financial-trading context, missing safety disclosures materially increases the risk of accidental loss, misuse of credentials, and operators enabling live execution without understanding the consequences.

Missing User Warnings

Medium

• Confidence: 90% confidence
• Finding: The README explicitly promotes autonomous live trading and quick-start execution, but it does not warn users about real financial loss, market volatility, configuration mistakes, or the difference between simulation and production behavior. In the context of an agent skill that can place real trades on Polymarket, this omission increases the chance that users will run it against live funds without understanding the risks or needed safeguards.

Missing User Warnings

Medium

• Confidence: 95% confidence
• Finding: The task description explicitly states that the agent will execute trades automatically every 5 minutes, but the configuration provides no user-facing warning, confirmation gate, or disclosure that live market actions may be irreversible and financially risky. In the context of an autonomous Polymarket trading bot, this omission is dangerous because users may enable or deploy the skill without understanding that it can place real trades on a schedule with direct monetary consequences.
