Treward Token - Smart Contract Audit Report
Summary
Treward is a new token where every transaction has a fee that is instantly redistributed among all token holders.
Notes on the contract:
- The total supply of the token is 20,000, delivered to the team upon deployment.
- No minting functions are present in the code.
- The Treward token includes a transfer fee. These fees are partially burned, and partially distributed among token holders.
- Users who hold tokens will automatically receive a proportional amount of the redistributed fees from the transaction tax.
- The owner sets the transfer fees and can change them at any time.
- The owner also has the ability to exclude and include users from transfer fees and rewards. Decentralized exchanges are intended to be excluded.
- The contract utilizes the SafeMath library to prevent overflows.
- Some gas optimizations can be achieved through marking functions external.
Audit Findings Summary
- No security issues were detected in the analysis.
- As with any presale, ensure trust in the team prior to investing. The team will have the ability to update tax rates.
- Date: March 9th, 2021
- Update Date: March 12th, 2021 - Add deployed address; update total supply
