FootBall Sport - Smart Contract Audit Report
FootBall Sport ($FBS) is a DeFi project that automatically provides rewards to users who hold the token via frictionless fee redistribution.
Notes on the Contract:
- FootBall Sport's code implements and builds upon the fee-redistribution features pioneered by Reflect Finance.
- The total supply of the token is 100,000,000 $FBS.
- No mint or burn functions exist, though the circulating supply can be decreased by sending tokens to burn address.
- At the time of writing this report, 100% of the total supply is in possession of the owner.
- There is a 2% fee that is redistributed to existing token holders instantly and automatically at the time of each transaction.
- The Burn address participates as a regular user in terms of reward distribution to act as a deflationary mechanism.
- The maximum number of tokens that can be sent on each transaction is 100% of the total supply.
- Ownership has not been renounced, so the maximum can be changed at any time.
- Some gas optimizations can be achieved through declaring functions external instead of public and some variables constant. As this contract is already deployed, this is merely informational.
- There exists some unnecessary logic in the fee calculation, but this has no tangible impact on security or user functionality. As this contract is already deployed, this is also merely informational.
- The team utilizes SafeMath to prevent overflows.
Audit Findings Summary
- No external threats were identified.
- As with any token, please ensure trust in the team prior to investing as they have notable control in the ecosystem.
