KURAI.addLiquidity(uint256,uint256) (#1185-1198) sends eth to arbitrary user
Dangerous calls:
- KURAIRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,operator(),block.timestamp) (#1190-1197)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

KURAI._writeCheckpoint(address,uint32,uint256,uint256) (#1458-1476) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1468)
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.


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.

KURAI.addLiquidity(uint256,uint256) (#1185-1198) ignores return value by KURAIRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,operator(),block.timestamp) (#1190-1197)
Ensure that all the return values of the function calls are used.

- Ownable.owner() (#219-221) (function)
Rename the local variables that shadow another component.

KURAI.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#1324-1365) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,Yeld::delegateBySig: signature expired) (#1363)
Avoid relying on block.timestamp.

KURAI.getChainId() (#1483-1487) uses assembly

Do not use evm assembly.

KURAI._transfer(address,address,uint256) (#1105-1132) compares to a boolean constant:
-recipient == BURN_ADDRESS || transferTaxRate == 0 || isExcluded(recipient) == true || sender == owner() (#1118)
Remove the equality to the boolean constant.

SafeMath.mul(uint256,uint256) (#79-91) is never used and should be removed
Remove unused functions.

Additional information: link

Pragma version>=0.6.2 (#976) allows old versions
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._functionCallWithValue(address,bytes,uint256,string) (#785-806):
- (success,returndata) = target.call{value: weiValue}(data) (#789)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable KURAI._delegates (#1266) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#181)" inContext (#175-184)
Remove redundant statements if they congest code but offer no value.

Variable IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#889) is too similar to IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#890)
Prevent variables from having similar names.

- MAX_SUPPLY = 10000000000000000000000000 (#1030)
Use: Ether suffix, Time suffix, or The scientific notation

transferOperator(address) should be declared external:
- KURAI.transferOperator(address) (#1253-1257)
Use the external attribute for functions never called from the contract.
