TaxHolderToken.changeReflectionFee(uint256) (#668-673) contains a tautology or contradiction:
- require(bool,string)(newReflectionFee >= 0,Reflection fee must be greater or equal to zero) (#669)
TaxHolderToken.changeBurnFee(uint256) (#675-680) contains a tautology or contradiction:
- require(bool,string)(burnFee_ >= 0,Burn fee must be greater or equal to zero) (#676)
TaxHolderToken.changeTaxFee(uint256) (#683-688) contains a tautology or contradiction:
- require(bool,string)(taxFee_ >= 0,Tax fee must be greater or equal to zero) (#684)
Fix the incorrect comparison by changing the value type or the comparison.

Contract ownership is not renounced (belongs to a wallet)

TaxHolderToken._reflectFee(uint256,uint256) (#877-883) performs a multiplication on the result of a division:
-tFee = tAmount * _reflectionFee / 100 (#878)
-rFee = tFee * currentRate (#879)
TaxHolderToken.burnFeeTransfer(address,uint256,uint256) (#910-918) performs a multiplication on the result of a division:
-tBurnFee = tAmount * _burnFee / 100 (#911)
-rBurnFee = tBurnFee * currentRate (#913)
TaxHolderToken.taxFeeTransfer(address,uint256,uint256) (#920-927) performs a multiplication on the result of a division:
-tTaxFee = tAmount * _taxFee / 100 (#921)
-rTaxFee = tTaxFee * currentRate (#923)
Consider ordering multiplication before division.

TaxHolderToken.constructor(uint256,string,string,uint8,uint256,uint256,uint256,address,address).feeAccount_ (#577) lacks a zero-check on :
- _feeAccount = feeAccount_ (#591)
TaxHolderToken.constructor(uint256,string,string,uint8,uint256,uint256,uint256,address,address).service_ (#577) lacks a zero-check on :
- address(service_).transfer(getBalance()) (#599)
Check that the address is not zero.

Contract name (TR3B-Manta) 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.

Contract has 15% buy tax and 13% sell tax.
Taxes are suspiciously high (over 10%) and contract ownership is not renounced. Token has a high risk of becoming a honeypot.

Average 30d PancakeSwap liquidity is less than $100. Token is either dead or inactive.

Average 30d PancakeSwap volume is less than $100. Token is either dead or inactive.

Average 30d number of PancakeSwap swaps is less than 1. Token is either dead or inactive.

Number of Binance Smart Chain (BSC) token holders is less than 100. Token is either dead or inactive. Ignore for presale.

Average PancakeSwap trading volume, liqudity, number of swaps are extremely low. Token seems to be dead.

Token is deployed only at one blockchain
