Website
Rayons Energy is a technology company focused on solar energy generation and its applications, seeking to consolidate the use of clean energy in the market. Initially, we are going to create a photovoltaic plant to use the energy to mine cryptocurrencies. In a second stage, we are going create a large-scale solar plant to sell the energy generated to companies via a consortium. In the third stage, we are going to create a business condominium within the plant so that companies that demand high energy consumption migrate their operations to the condominium and, by renting our warehouses, reduce their costs with the energy bill, in addition to contributing to sustainability and may receive government incentives for using energy from renewable sources.

RAYONSENERGY.lockToBuyOrSellForTime(uint256,uint256) (#660-669) uses a dangerous strict equality:
- lastBuyOrSellTime == 0 (#662)
Don't use strict equality to determine if an account has enough Ether or tokens.

RAYONSENERGY.addLiquidity(uint256,uint256) (#1070-1081) ignores return value by PancakeSwapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1072-1079)
Ensure that all the return values of the function calls are used.

RAYONSENERGY.lockToBuyOrSellForTime(uint256,uint256) (#660-669) uses timestamp for comparisons
Dangerous comparisons:
- lastBuyOrSellTime == 0 (#662)
- crashTime >= lockTime (#666)
Avoid relying on block.timestamp.

SafeMath.trySub(uint256,uint256) (#38-43) is never used and should be removed
Remove unused functions.
Additional information: link
RAYONSENERGY._rTotal (#531) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
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.

solc-0.8.9 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.functionDelegateCall(address,bytes,string) (#202-211):
- (success,returndata) = target.delegatecall(data) (#209)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable RAYONSENERGY.setMaxRxPercent(uint256).maxRxPercent (#721) is too similar to RAYONSENERGY.setMaxTxPercent(uint256).maxTxPercent (#717)
Prevent variables from having similar names.
