EviToken.addLiquidity(uint256,uint256) (#1284-1297) sends eth to arbitrary user
Dangerous calls:
- eviRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,operator(),block.timestamp) (#1289-1296)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

EviToken._writeCheckpoint(address,uint32,uint256,uint256) (#1599-1617) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1609)
Don't use strict equality to determine if an account has enough Ether or tokens.

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.

Redundant expression "this (#24)" inContext (#18-27)
Remove redundant statements if they congest code but offer no value.

EviToken._transfer(address,address,uint256) (#1194-1229) performs a multiplication on the result of a division:
-taxAmount = amount.mul(transferTaxRate).div(10000) (#1215)
-burnAmount = taxAmount.mul(burnRate).div(100) (#1216)
Consider ordering multiplication before division.
