fBNB [FEG Wrapped BNB] Token

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

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

fBNB.deposit() (#590-605) performs a multiplication on the result of a division:
-df = fee / 8 (#595)
-rBnbBalance[op] += ((df * r) / t) (#601)
fBNB.withdraw(uint256) (#607-625) performs a multiplication on the result of a division:
-wf = fee / 8 (#611)
-rBnbBalance[op] += ((wf * r) / t) (#621)
fBNB._transfer(address,address,uint256) (#682-709) performs a multiplication on the result of a division:
-fee = amt / 100 (#687)
-rBnbSupply -= ((fee * r) / t) (#706)
Consider ordering multiplication before division.

fBNB.constructor() (#523-528) ignores return value by EnumerableSet.add(excluded,address(0)) (#526)
fBNB.excludeFromFees(address) (#635-643) ignores return value by EnumerableSet.add(excluded,account) (#642)
fBNB.includeInFees(address) (#645-650) ignores return value by EnumerableSet.remove(excluded,account) (#649)
Ensure that all the return values of the function calls are used.

fBNB.rBnbToEveryone(uint256) (#627-633) should emit an event for:
- rBnbSupply -= ((amt * r) / t) (#631)
- feesAccrued += amt (#632)
Emit an event for critical parameter changes.

fBNB.setOp(address,address).opper (#724) lacks a zero-check on :
- op = opper (#726)
fBNB.setOp(address,address).opper2 (#724) lacks a zero-check on :
- op2 = opper2 (#727)
Check that the address is not zero.

Pragma version^0.8.1 (#4) allows old versions
solc-0.8.1 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in Address.sendValue(address,uint256) (#404-410):
- (success) = recipient.call{value: amount}() (#408)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#470-491):
- (success,returndata) = target.call{value: weiValue}(data) (#474)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
