Industries We Serve

How We've Helped Our Clients Identify Security Vulnerabilities

Investment & Yield Farming Contracts

What we found:

CRITICAL:
  • Reentrancy Attack – A malicious actor could withdraw funds repeatedly before the original transaction is approved, draining the contract funds.

  • Unchecked Return Values—Failing to check the return value of an external call could result in a loss of funds or an inconsistent contract state.

HIGH:
  • Front-Running – Transactions can be manipulated by miners or observers, leading to financial loss or unfair advantages.

  • Incorrect Access Control – An attacker could gain unauthorized access to critical functions, leading to loss or theft of funds.

  • And many more…

Token Issuance & Minting Contracts

What we found:

HIGH:
  • Integer Overflow/Underflow – Improper arithmetic operations can lead to the minting or burning of a large number of tokens, destabilizing the token economy.

  • Lack of Proper Event Logging – Inadequate logging can obscure contract operations, hindering issue diagnosis and contract transparency.

  • Insecure Randomness – Predictability in random number generation can be exploited by attackers to influence contract outcomes.

  • And many more..

Gaming & NFT Platforms

What we found:

HIGH:
  • Broken Delegation – Delegated calls to untrusted contracts can lead to unexpected behaviour or exploits.

  • Improper State Change – Flaws in state-changing functions can allow attackers to disrupt the contract’s intended workflow.

  • Insecure Dependency Management – Reliance on insecure or outdated contract dependencies can introduce vulnerabilities.

  • And many more…
