T99NFT Token

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Contract ownership is not renounced (belongs to a wallet)

T99NFTToken.constructor(address[],uint256[],address)._burntAddrs (contracts/T99NFT.sol#30) lacks a zero-check on :
- burntAddr = _burntAddrs (contracts/T99NFT.sol#43)
Check that the address is not zero.

T99NFTToken.transfer(address,uint256) (contracts/T99NFT.sol#56-79) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > startLock + 63072000,Lock up period is not over) (contracts/T99NFT.sol#64-67)
- require(bool,string)(block.timestamp > startLock + 7862400,Lock up period is not over) (contracts/T99NFT.sol#70-73)
T99NFTToken.transferFrom(address,address,uint256) (contracts/T99NFT.sol#81-104) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > startLock + 63072000,Lock up period is not over) (contracts/T99NFT.sol#88-91)
- require(bool,string)(block.timestamp > startLock + 7862400,Lock up period is not over) (contracts/T99NFT.sol#94-97)
Avoid relying on block.timestamp.

T99NFTToken.transfer(address,uint256) (contracts/T99NFT.sol#56-79) compares to a boolean constant:
-isExcludedFromFee[_msgSender()] == true (contracts/T99NFT.sol#75)
T99NFTToken.transferFrom(address,address,uint256) (contracts/T99NFT.sol#81-104) compares to a boolean constant:
-isExcludedFromFee[from] == true (contracts/T99NFT.sol#100)
Remove the equality to the boolean constant.

Different versions of Solidity is used:
- Version used: ['0.8.13', '^0.8.0']
- ^0.8.0 (@openzeppelin/contracts/access/Ownable.sol#4)
- ^0.8.0 (@openzeppelin/contracts/token/ERC20/ERC20.sol#4)
- ^0.8.0 (@openzeppelin/contracts/token/ERC20/IERC20.sol#4)
- ^0.8.0 (@openzeppelin/contracts/token/ERC20/extensions/IERC20Metadata.sol#4)
- ^0.8.0 (@openzeppelin/contracts/utils/Context.sol#4)
- 0.8.13 (contracts/T99NFT.sol#3)
Use one Solidity version.

ERC20._mint(address,uint256) (@openzeppelin/contracts/token/ERC20/ERC20.sol#257-267) has costly operations inside a loop:
- _totalSupply += amount (@openzeppelin/contracts/token/ERC20/ERC20.sol#262)
Use a local variable to hold the loop computation result.

Context._msgData() (@openzeppelin/contracts/utils/Context.sol#21-23) is never used and should be removed
Remove unused functions.

Pragma version^0.8.0 (@openzeppelin/contracts/access/Ownable.sol#4) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/token/ERC20/ERC20.sol#4) allows old versions

Pragma version^0.8.0 (@openzeppelin/contracts/utils/Context.sol#4) allows old versions
Pragma version0.8.13 (contracts/T99NFT.sol#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.13 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.
