Symmetric | Smart Contract Audit Report | 2021 | QuillAudits

QuillAudits has officially announced the successful completion of the smart contract security audit for Symmetric 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.

Cent is a non-custodial mobile wallet designed to make investing in Crypto & DeFi simple, easy & secure.
