Real-World Smart Contract Vulnerabilities we identified and resolved
Don’t let a single line of code vulnerability jeopardize your project’s success. Here are some real-world examples of critical issues our smart contract audits have identified and helped mitigate:

Forced Retention Of User Funds in Multi-Tier Locking Dynamics

We recently identified a bug in a client’s staking platform that could have unintentionally frozen user funds due to mismatched lock-in periods across different tiers. A smart contract audit can help expose these complexities and ensure your platform functions as intended.

Misapplied Flag Leading to Unintended Fees After Bond Maturity

Our team identified a vulnerability in a bond program that could have incorrectly charged users early redemption fees even after their bonds matured. This highlights the importance of a smart contract auditor’s expertise in identifying potential logic errors that could impact user finances.

Bridge Bug Exposed Users with Special Tokens

Another audit of the bridge revealed a critical issue where it treated all tokens equally. This could have led to problems with specific token types. By using our smart contract audit services client was able to ensure the bridge handles diverse tokens securely.

SOL Withdrawal Bug in Liquidity Pool

Another audit uncovered a bug in a liquidity pool’s smart contract that resulted in incorrect withdrawal deductions. This could have caused discrepancies in asset tracking.  A thorough smart contract audit can identify these issues and safeguard the pool’s financial health.
