Audit Summary
The system users should acknowledge all the risks summed up in the risks section of the report
System Overview
The NonKYC iOS Progressive Web Application (PWA) provides a mobile-first interface for account creation, balance management, deposits/withdrawals, and spot trading. It runs in Safari/WebKit with a lightweight app-shell, uses REST APIs for data and actions, and integrates Cloudflare for bot/challenge protections.
Key Capabilities
Account: Email signup/login, OTP/PIN, profile & password reset, basic 2FA.
Wallet: Balances (available/held/pending), deposit addresses, withdrawals, history.
Trading: Market data (tickers/orderbook/trades), place market/limit orders, open orders & history.
Support & Settings: Tickets/alerts, language/preferences, security options.
Findings
Code ― | Title | Status | Severity | |
|---|---|---|---|---|
| F-2025-1341 | Lack of Rate Limiting on Verification Endpoint | fixed | Medium | |
| F-2025-1354 | Arbitrary Input Accepted as Wallet Address | accepted | Low | |
| F-2025-1349 | Verbose Error Disclosure (Stack Trace & Paths Leaked) | fixed | Low |
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. |

Appendix 3. Additional Valuables
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.
