Colizeum

Smart Contract Audit Report

Audit Summary

Colizeum is a new ERC-20 token on Ethereum.

For this audit, we reviewed the project team's Colizeum contract at 0x436dA116249044E8B4464F0Cf21Dd93311d88190 on the Ethereum Mainnet.

Audit Findings

Please ensure trust in the team prior to investing as they currently own 99.99% of the total supply.
Date: March 25th, 2022.

Contract Overview

The total supply of the token is set to 1 billion $ZEUM [1,000,000,000].
No mint or burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address.
At the time of writing this report, 99.99% of the total supply belongs to a wallet controlled by the team.

There are no fees associated with transferring tokens.
No ownership-restricted functions are present.
As the contract is deployed with Solidity v0.8.5, it is protected from overflows/underflows.
The contract complies with the ERC-20 token standard.

What is a Solidity Audit?

Typically, a smart contract audit is a comprehensive review process designed to discover logical errors, security vulnerabilities, and optimization opportunities within code. A Solidity 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.
