white paper

Coin of Nature (CON) is a community-based project that was launched at the beginning of July 2021. Due to the type of the project Due to the type of this project, the timeline is based on the number of holders rather than dates. The detailed roadmap can be found on the official website.

The major aim of the project is not only to promote sports and a healthy lifestyle but also to develop a sustainable ecosystem based on innovative solutions. The project focuses on using the latest technologies and applying them in the Blockchain.

During the first stage of the project, the CON token has been developed. The token is deflationary and based on BSC20 network. It is also worth noting that 5% of each completed transaction is distributed among all holders, while another 5% goes to the liquidity pool.

Ownable.unlock() (#473-478) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#475)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#371-392) uses assembly
- INLINE ASM (#384-387)
Do not use evm assembly.

Additional information: link

SafeMath.mod(uint256,uint256,string) (#239-242) is never used and should be removed
Remove unused functions.

Additional information: link

CoinofNature._previousLiquidityFee (#721) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#371-392):
- (success,returndata) = target.call{value: weiValue}(data) (#375)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable CoinofNature._maxTxAmount (#729) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#251)" inContext (#245-254)
Remove redundant statements if they congest code but offer no value.

Variable CoinofNature._transferBothExcluded(address,address,uint256).rTransferAmount (#872) is too similar to CoinofNature._transferStandard(address,address,uint256).tTransferAmount (#1126)
Prevent variables from having similar names.

CoinofNature.slitherConstructorVariables() (#695-1158) uses literals with too many digits:
- numTokensSellToAddToLiquidity = 500000 * 10 ** 6 * 10 ** 9 (#730)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

CoinofNature.numTokensSellToAddToLiquidity (#730) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

isExcludedFromFee(address) should be declared external:
- CoinofNature.isExcludedFromFee(address) (#990-992)
Use the external attribute for functions never called from the contract.
