DinoToken - Smart Contract Audit Report

Summary

DinoToken Token Audit Report DinoToken is a new upcoming token project with a 5% fee-on-transfer mechanism.

For this audit we reviewed the project's token contract using code provided to us by the team. The code is available below.

Notes of the Token Contract:
  • The total supply of the token is 500,000,000.
  • The team will receive 100% of the supply upon deployment.
  • No minting functions are accessible after deployment; though a burn function is present.
  • There is a 5% tax on transfers, an equal portion of which is sent to 5 diferent addresses controlled by the team.
  • The owner can update the 5 addresses which receive funds from the transfer tax at any time. The event emitted for this tax is not accurate, but this does not impact user functionality.
  • The owner can also exclude addresses from the fee mechanism.
  • The contract utilizes Solidity 0.8.* which has built-in overflow checks, removing the need for SafeMath.

Audit Findings Summary
  • No issues from external attackers were identified.
  • As with any presale, ensure trust in the team prior to investing. The project team is anonymous.
  • Date: April 18th, 2021.
