USDT Swap Trading API: Allows users to trade perpetual contracts settled in USDT, offering similar features to the Spot Trading API but tailored for derivatives trading.
The application manages several critical asset categories:
User Data: Personal information, account balances, and transaction history.
Authentication Credentials: API keys, tokens, and secret keys used to access the APIs.
Financial Transactions: Order placements, cancellations, and trade executions.
Market Data: Real-time and historical price information.

Appendix 1. Severity Definitions
Findings are categorized based on their potential impact and assigned a severity level using the Common Vulnerability Scoring System (CVSS) version 4.0: →
Severity | Description |
|---|---|
Critical | These issues present a major security vulnerability that poses a severe risk to the system. They require immediate attention and must be resolved to prevent a potential security breach or other significant harm. |
High | These issues present a significant risk to the system, but may not require immediate attention. They should be addressed in a timely manner to reduce the risk of the potential security breach. |
Medium | These issues present a moderate risk to the system and cannot have a great impact on its function. They should be addressed in a reasonable time frame, but may not require immediate attention. |
Low | These issues present no risk to the system and typically relate to the code quality problems or general recommendations. They do not require immediate attention and should be viewed as a minor recommendation. |

Frameworks and Methodologies
This security assessment was conducted in alignment with recognised penetration testing standards, methodologies and guidelines, including the NIST SP 800-115 – Technical Guide to Information Security Testing and Assessment →, the Penetration Testing Execution Standard (PTES) →, and the OWASP Testing Guide →. These assets provide a structured foundation for planning, executing, and documenting technical evaluations such as vulnerability assessments, exploitation activities, and security code reviews. Hacken’s internal penetration testing methodology extends these principles to Web2 and Web3 environments to ensure consistency, repeatability, and verifiable outcomes.
