white paper

JaiHo is India’s first community-based crypto project with low supply, which is deflationary over time. JaiHo’s unique revenue-sharing model includes a charity mission. We have built a community before releasing a token—No Big Promises, just a loyal Community to grow over time.

Ownable.unlock() (#477-482) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp < _lockTime,Contract is locked until 7 days) (#479)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#375-396) uses assembly
- INLINE ASM (#388-391)
Do not use evm assembly.

SafeMath.mod(uint256,uint256,string) (#243-246) is never used and should be removed
Remove unused functions.

Additional information: link

JaiHo._previousCharityFee (#733) is set pre-construction with a non-constant function or state variable:
- _charityFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Additional information: link

solc-0.8.4 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._functionCallWithValue(address,bytes,uint256,string) (#375-396):
- (success,returndata) = target.call{value: weiValue}(data) (#379)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable JaiHo._maxTxAmount (#741) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#255)" inContext (#249-258)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable JaiHo._transferBothExcluded(address,address,uint256).rTransferAmount (#886) is too similar to JaiHo._getTValues(uint256).tTransferAmount (#915)
Prevent variables from having similar names.

JaiHo.slitherConstructorVariables() (#699-1189) uses literals with too many digits:
- numTokensSellToAddToLiquidity = 500000000000000000 * 10 ** 9 (#742)
Use: Ether suffix, Time suffix, or The scientific notation

JaiHo.deadWallet (#729) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

setSwapAndLiquifyEnabled(bool) should be declared external:
- JaiHo.setSwapAndLiquifyEnabled(bool) (#1182-1185)
Use the external attribute for functions never called from the contract.
