About Oobit
Oobit is pioneering the future of global crypto payments, enabling users to pay with cryptocurrency everywhere—in-store, online, or on the go—using their own wallet. Their platform bridges the gap between digital assets and everyday commerce, making crypto spending as seamless as traditional payments. Built on Solana for speed and low transaction costs, Oobit's infrastructure includes sophisticated smart contracts that power their payment ecosystem and user rewards mechanisms.
Security Requirements
As Oobit scales their crypto payment infrastructure to serve a global user base, ensuring the security of their smart contracts is paramount. Payment systems require the highest level of trust and reliability—any vulnerability could impact user funds and undermine confidence in the platform.
The engagement scope encompassed Oobit's Solana-based program built with the Anchor framework, covering authentication and authorization, mathematical correctness in financial calculations, economic attack vectors, state management, and emergency controls.
Audit Methodology
FailSafe's security team conducted a comprehensive audit combining manual code review with automated analysis, targeting the full attack surface of Oobit's payment infrastructure:
Mathematical Correctness Analysis
Rigorous verification of reward calculations, APY computation, and financial arithmetic to prevent inflation attacks, rounding errors, and precision loss in payment operations.
Economic Attack Vector Assessment
Deep analysis of potential manipulation vectors including dust attacks, timing exploits, and denial-of-service scenarios that could impact payment processing or drain funds.
Access Control & Authorization Review
Comprehensive review of authentication mechanisms, authority transfer patterns, and privilege escalation risks to ensure only authorized operations can be executed.
State Management & Safety Controls
Validation of account handling, reentrancy protection, pause functionality, and emergency controls critical for payment infrastructure resilience.
Confidential Partnership
In accordance with Oobit's security and business requirements, the detailed findings and specific vulnerabilities identified during this audit remain confidential. Our partnership focused on addressing security considerations across multiple severity levels, with the development team demonstrating excellent responsiveness in implementing fixes.
The audit identified findings across multiple severity levels related to financial calculations, input handling, and security controls. The majority of findings have been successfully remediated with FailSafe providing verification testing.
Partnership Impact
Through close collaboration with Oobit's development team, FailSafe provided comprehensive security guidance that strengthened the platform's payment infrastructure. The engagement covered:
- Input validation and bounds checking to prevent parameter manipulation and ensure safe initialization of payment contracts
- Integer overflow protection and precision handling in all financial calculations to prevent fund drainage attacks
- Reentrancy guards and CPI security measures to protect against cross-program invocation exploits
- Authority transfer mechanisms and emergency pause functionality for robust operational security controls
