Green Life Energy Global (GNL) is a
community token that allows users to make
payments based on renewable energy and
recycling products and services, share
assets, and send money between friends
and family.

A crypto-based token on renewable energy and recycling, GNL is about bringing the blockchain a bit further not just only creating the next big crypto asset, but also changing the whole financial sector on energy and recycling payments. Imagine a world where everything is powered by renewable energy? This is what we are building.

Use Cases: Crypto Miners and Household’s renewable energy power supply (Bill payments in GNL), GNL Wallet, Payments of Renewable Energy and Recycling Products and Services.

GreenLifeEnergy.contractSwap() (#447-485) sends eth to arbitrary user
Dangerous calls:
- (MarketingSuccess) = address(_taxWallets.swap).call{gas: 30000,value: amountBNBMarketing}() (#471)
- dexRouter.addLiquidityETH{value: BNBToLP}(address(this),amountToLiquify,0,0,address(this),block.timestamp) (#475-482)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Contract ownership is not renounced (belongs to a wallet)


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.

GreenLifeEnergy.contractSwap() (#447-485) ignores return value by dexRouter.addLiquidityETH{value: BNBToLP}(address(this),amountToLiquify,0,0,address(this),block.timestamp) (#475-482)
Ensure that all the return values of the function calls are used.

GreenLifeEnergy.setLpPair(address,bool) (#304-314) uses timestamp for comparisons
Dangerous comparisons:
- timeSinceLastPair != 0 (#308)
- require(bool,string)(block.timestamp - timeSinceLastPair > 259200,3 Day cooldown.!) (#309)
GreenLifeEnergy._transfer(address,address,uint256) (#395-445) uses timestamp for comparisons
Dangerous comparisons:
- lastSwap + contractSwapTimer < block.timestamp (#434)
Avoid relying on block.timestamp.

Additional information: link

GreenLifeEnergy.setLpPair(address,bool) (#304-314) compares to a boolean constant:
-enabled == false (#305)
Remove the equality to the boolean constant.

Pragma version>=0.6.0<0.9.0 (#6) is too complex
solc-0.8.12 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.
