BASED [EverBased] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

EverBased.swapBack() (#439-463) sends eth to arbitrary user
Dangerous calls:
- marketingFeeReceiver.transfer(amountETHMarketing) (#461)
- devFeeReceiver.transfer(amountETHDev) (#462)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Contract ownership is not renounced (belongs to a wallet)

EverBased.totalFee (#215) is set pre-construction with a non-constant function or state variable:
- devFee + marketingFee + buyBackFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
