Audit Findings

No findings were identified.
Date: January 25th, 2024.

Contract Overview

  • The total supply of the token is currently 700 million $CERT [700,000,000].
  • No mint functions are accessible beyond deployment.
  • Any user can burn their own tokens to reduce the total supply at any time.
  • Any user can burn tokens on another user's behalf up to their granted allowance at any time.
  • At the time of writing this report, there are 4,073 total token holders. The token allocation is as follows:
    • The first six holders own a cumulative 56.86% of the total supply.
    • The next six holders own a cumulative 42.14% of the total supply.
  • As the contract is deployed with Solidity v0.8.18, it is safe from any possible overflows/underflows.
  • The contract complies with the ERC-20 token standard.

What is a SourceHat Audit?

Typically, a smart contract audit is a comprehensive review process designed to discover logical errors, security vulnerabilities, and optimization opportunities within code. A SourceHat Audit takes this a step further by verifying economic logic to ensure the stability of smart contracts and highlighting privileged functionality to create a report that is easy to understand for developers and community members alike.

How Do I Interpret the Findings?

Each of our Findings will be labeled with a Severity level. We always recommend the team resolve High, Medium, and Low severity findings prior to deploying the code to the mainnet. Here is a breakdown on what each Severity level means for the project:

  • High severity indicates that the issue puts a large number of users' funds at risk and has a high probability of exploitation, or the smart contract contains serious logical issues which can prevent the code from operating as intended.
  • Medium severity issues are those which place at least some users' funds at risk and has a medium to high probability of exploitation.
  • Low severity issues have a relatively minor risk association; these issues have a low probability of occurring or may have a minimal impact.
  • Informational issues pose no immediate risk, but inform the project team of opportunities for gas optimizations and following smart contract security best practices.
