DinoToken - Smart Contract Audit Report
Summary
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.
