white paper

AlvareNet is creating an ecosystem of Dapps making it easier and more secure to navigate in the crypto sphere. The primary product will be the creation of a P2P platform to secure payments of goods and services using crypto as payment, since it is something that is missing in the cryptocurrency space right now.

report
Token is either risky or in presale. For presale 30+ is a fine score.

AlvareNet.emergencyWithdraw(uint256,address) (contracts/token.sol#816-820) ignores return value by token.transfer(msg.sender,_amount) (contracts/token.sol#819)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

AlvareNet.setproxyContract(address).contractaddress (contracts/token.sol#247) lacks a zero-check on :
- proxycontract = contractaddress (contracts/token.sol#250)
Check that the address is not zero.

Strings.toString(uint256) (@openzeppelin/contracts/utils/Strings.sol#14-34) is never used and should be removed
Remove unused functions.

Additional information: link

AlvareNet._previousOtherFee (contracts/token.sol#55) is set pre-construction with a non-constant function or state variable:
- otherFee
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.

Additional information: link

solc-0.8.4 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) (@openzeppelin/contracts/utils/Address.sol#178-187):
- (success,returndata) = target.delegatecall(data) (@openzeppelin/contracts/utils/Address.sol#185)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Constant AlvareNet.maxFeeTotal (contracts/token.sol#57) is not in UPPER_CASE_WITH_UNDERSCORES
Follow the Solidity naming convention.

Variable AlvareNet.reflectionFromToken(uint256,bool).rTransferAmount (contracts/token.sol#301) is too similar to AlvareNet._transferStandard(address,address,uint256).tTransferAmount (contracts/token.sol#710)
Prevent variables from having similar names.

Additional information: link

AlvareNet.slitherConstructorConstantVariables() (contracts/token.sol#12-822) uses literals with too many digits:
- _tTotal = 1000000000000000 * 10 ** 9 (contracts/token.sol#38)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

emergencyWithdraw(uint256,address) should be declared external:
- AlvareNet.emergencyWithdraw(uint256,address) (contracts/token.sol#816-820)
Use the external attribute for functions never called from the contract.
