The Direwolf - Smart Contract Audit Report

Summary

Direwolf is a new project that provides automated rewards to users who hold the token.

For this audit, we reviewed Direwolf's token contract, provided to us by the team.

Notes on the contract:
The total supply of the token is one quintrillion.
No mint or burn functions exist, though the circulating supply can be decreased by sending tokens to 0x...dead.
100% of the 2% fee charged on token transfers is redistributed to existing token holders instantly and automatically at the time of each transaction.
The owner can exclude any address from the fee mechanism.
Some gas optimizations can be achieved through declaring functions external instead of public and some variables constant.
Utilization of SafeMath to prevent overflows.

Audit Findings Summary
No external threats were identified.
The team holds a modest amount of tokens.
