Reasons Why You May Need a
Smart Contract Audit

Secure Your Project & User Funds

A smart contract audit identifies vulnerabilities that could be exploited by hackers, potentially leading to stolen funds and project collapse. Don’t wait for a disaster – secure your project today!

Build
Trust

A successful security audit report demonstrates your commitment to security and best practices. This transparency builds trust with investors and users, making your project more attractive for funding and adoption.

Proactive Defense Against Exploits

Hackers are constantly searching for vulnerabilities. A comprehensive smart contract audit proactively identifies these weaknesses before they can be exploited, saving your project from costly attacks and reputational damage.

Code Optimization and Efficiency

Beyond security, smart contract audits can reveal inefficiencies in your code. This allows for optimization, reducing gas costs associated with smart contract execution, ultimately saving you money in the long run.
Some Common Smart Contract Vulnerabilities

Integer Overflow / Underflow

Incorrect handling of mathematical operations can lead to unexpected behavior and potential theft of funds.

Reentrancy Attacks

Exploiting a loophole where a function can be called multiple times before the first call finishes, allowing attackers to manipulate data.

Access Control Issues

Unauthorized access to sensitive functions or data within the smart contract.

Infinite Loops

Bugs that cause the smart contract to get stuck in a loop, rendering it unusable.

Gas Optimization Issues

Inefficient code that leads to unnecessarily high transaction fees.

Incorrect Functionality

The smart contract doesn't behave as intended, leading to unintended consequences.
Real-World Smart Contract Vulnerabilities we identified and resolved

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.
