Pekingese Inu Token

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

Tokenomics._getFeeStruct(uint256) (#424-430) contains a tautology or contradiction:
- require(bool,string)(index >= 0 && index < fees.length,FeesSettings._getFeeStruct: Fee index out of bounds) (#425-428)
Fix the incorrect comparison by changing the value type or the comparison.

Contract ticker (Pekingese Inu) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

BaseRfiToken._getValues(uint256,uint256) (#905-930) performs a multiplication on the result of a division:
-tTotalFees = tAmount.mul(feesSum).div(FEES_DIVISOR) (#916)
-rTotalFees = tTotalFees.mul(currentRate) (#920)
BaseRfiToken._redistribute(uint256,uint256,uint256,uint256) (#985-996) performs a multiplication on the result of a division:
-tFee = amount.mul(fee).div(FEES_DIVISOR) (#991)
-rFee = tFee.mul(currentRate) (#992)
SafeToken._burn(uint256,uint256,uint256,uint256) (#1307-1318) performs a multiplication on the result of a division:
-tBurn = amount.mul(fee).div(FEES_DIVISOR) (#1313)
-rBurn = tBurn.mul(currentRate) (#1314)
SafeToken._takeFee(uint256,uint256,uint256,address,uint256) (#1320-1337) performs a multiplication on the result of a division:
-tAmount = amount.mul(fee).div(FEES_DIVISOR) (#1327)
-rAmount = tAmount.mul(currentRate) (#1328)
Consider ordering multiplication before division.

Pragma version^0.8.9 (#12) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.9 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.
