FEG - Smart Contract Audit Report
FEG created a platform where fees charged from transactions are shared among token holders. Fee sharing is instant, increasing the balance of all token holders with each transaction.
Notes on the contract:
- FEG is a fork of Reflect Finance (RFI). The key notable differences are the transfer tax which is 2x that of RFI, and the increased total supply.
- The total supply of the token is 100 quadrillion.
- No mint or burn functions exist, though the circulating supply can be decreased by sending tokens to 0x...dead.
- 57% of the total supply has been sent to 0xdead on Ethereum, and 54% on BSC.
- 1% of the supply on Ethereum and 0.75% of the supply on BSC are in liquidity pools. Some additional liquidity is locked in custom liquidity pools deployed by the team until the end of June 2021.
- Nearly all of the liquidity on both chains has been locked by the team.
- 3 wallets hold slightly more than the LP pool on Ethereum, and 6 wallets on BSC. These wallets are not controlled by the team.
- 100% of the 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.
- The doubling of the standard fee performs a multiplication on the result of a division. While this can lead to slightly less accurate results, the large supply of the token makes this impact negligible at most.
- 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.
- Utilization of SafeMath to prevent overflows.
