FEG - Smart Contract Audit Report

Summary

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.

FEG is deployed at 0xacfc95585d80ab62f67a14c566c1b7a49fe91167 on the Binance Smart Chain, and 0x389999216860ab8e0175387a0c90e5c52522c945 on the Ethereum Mainnet.

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.
