Dfyn | Smart Contract Audit Report | 2021 | QuillAudits

QuillAudits has officially announced the successful completion of the smart contract security audit for Dfyn Smart contract. A meticulous and professional security audit was conducted, which checked & ensured the following imperative points:

— The overall quality of code.
— Use of best practices.
— Code documentation and comments match logic and expected behavior.
— Token distribution and calculations are as per the intended behave mentioned in the whitepaper.
— Efficient use of gas.
— Code is safe from re-entrancy and other vulnerabilities.

The audit rigorously checked for any signs of vulnerabilities like Re-entrancy, Timestamp Dependence, Gas Limit, and Loops, DoS with Block Gas Limit, Unchecked external call, Unchecked math, Unsafe type inference, etc., as the contract went through Structural, Static and Dynamic analysis as well as methodical Code Review.

Audit Report Summary

The use of smart contracts is simple and the code is relatively small. Altogether the code is written and demonstrates effective use of abstraction, separation of concern, and modularity. But there are a few issues/vulnerabilities to be tackled at various security levels, it is recommended to fix them before deploying the contract on the main network. Given the subjective nature of some assessments, it will be up to the Product Owner to decide whether any changes should be made.
