Case Study: Black-box Precision Audit (GT Protocol)

📌 Overview

This research documents a "black-box" security analysis of a major trading protocol interface. By performing network forensics and API response analysis, I identified critical inconsistencies in decimal precision handling.

🔍 Vulnerability Details

• Issue: Inconsistent decimal normalization across API endpoints.
• Finding: The profit field returns 8 decimal places (raw data), while total_profit is truncated to 2 decimals within the same object.
• Risk: In DeFi, lack of unified math libraries for rounding can lead to cumulative "Precision Loss" or "Ghost Debt" vulnerabilities.

🛠️ Methodology

1. Network Interception: Analyzing Fetch/XHR traffic via Chrome DevTools.
2. Data Mapping: Tracing UI display bugs back to raw JSON backend responses.
3. Logic Verification: Comparing rounding directions between different data modules.
