white paper

LIGHT DEFI is an alternative to the financial system based on protocols and technological and industrial options to provide consumers with access to quality energy, based on a clean, reliable and sustainable energy matrix.
Deflationary BEP-20 token that directly finances the construction of photovoltaic solar power plants in Brazil and worldwide. Brazil is one of the countries with the greatest potential for generating renewable energy in the world.

You acquire tokens and as a reward you will receive more tokens from the profits earned by the solar power plants.

Token seems to be (relatively) fine. It still become a scam, but probability is moderate.

LightDeFi.addLiquidity(uint256,uint256) (#1061-1074) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1066-1073)
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.

LightDeFi.setcharityWallet(address).newWallet (#1166) lacks a zero-check on :
- charityWallet = newWallet (#1167)
Check that the address is not zero.

Low level call in Address.sendValue(address,uint256) (#308-314):
- (success) = recipient.call{value: amount}() (#312)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#374-395):
- (success,returndata) = target.call{value: weiValue}(data) (#378)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
