white paper

Elonium is a startup initiated in the Dutch construction industry. The ELNC token is a project also created by them. The CEO of Elonium, Sander Struive has spent many years in construction firsthand and has noticed many problems affecting the general safety, efficiency and quality of construction projects, we're talking about problems like miscommunication due to language barriers, outdated learning and instructional material and more issues on a greater scale.

Elonium plans to tackle these problems head on and resolve them, starting with the introduction of a mobile application which will provide a digital construction platform hosting up to date videos and instructional materials for projects and architect schools. It will also host a social platform where people involved in the industry may share their own works or browse others.

A case scenario could be that a contractor hires workers for his project by checking out their portfolios on the app. Our Token will also act as currency to purchase various commodities using the application, ranging from merch to construction materials.

EloniumCoin.addLiquidity(uint256,uint256) (#898-911) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#903-910)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.

EloniumCoin.addLiquidity(uint256,uint256) (#898-911) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#903-910)
Ensure that all the return values of the function calls are used.

EloniumCoin._approve(address,address,uint256).owner (#802) shadows:
- Ownable.owner() (#278-280) (function)
Rename the local variables that shadow another component.

EloniumCoin.setMaxTxPercent(uint256) (#752-754) should emit an event for:
- _maxTxAmount = _tTotal.mul(maxTxPercent).div(100) (#753)
Emit an event for critical parameter changes.

EloniumCoin.setUniswapPair(address).p (#768) lacks a zero-check on :
- uniswapV2Pair = p (#769)
Check that the address is not zero.

Ownable.unlock() (#325-330) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#327)
Avoid relying on block.timestamp.

SafeMath.mod(uint256,uint256,string) (#231-234) is never used and should be removed
Remove unused functions.

Additional information: link

EloniumCoin._previousBurnFee (#566) is set pre-construction with a non-constant function or state variable:
- _burnFee
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.

Variable EloniumCoin._maxTxAmount (#574) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#243)" inContext (#237-246)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable EloniumCoin._transferStandard(address,address,uint256).rTransferAmount (#953) is too similar to EloniumCoin._getTValues(uint256).tTransferAmount (#1005)
Prevent variables from having similar names.

EloniumCoin.slitherConstructorVariables() (#537-1056) uses literals with too many digits:
- numTokensSellToAddToLiquidity = 500000000 * 10 ** 9 (#575)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

EloniumCoin._symbol (#558) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

isExcludedFromFee(address) should be declared external:
- EloniumCoin.isExcludedFromFee(address) (#798-800)
Use the external attribute for functions never called from the contract.
