MIRAI Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Mirai._transferBNB(address,uint256) (Mirai.sol#87-89) sends eth to arbitrary user
Dangerous calls:
- _to.transfer(amount) (Mirai.sol#88)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Mirai._transferMIRAIToken(address,uint256) (Mirai.sol#90-92) ignores return value by ERC20(address(this)).transfer(_to,amount) (Mirai.sol#91)
Mirai._transferAllTokensContracts(ERC20,address,uint256) (Mirai.sol#93-95) ignores return value by _token.transfer(_to,amount) (Mirai.sol#94)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Combination 2: Unchecked transfer + 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.

Pragma version^0.8.0 (ERC20.sol#3) allows old versions

Pragma version0.8.0 (SafeMath.sol#3) allows old versions
solc-0.8.0 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.

ERC20._updateListHistory(uint256,uint256).nV (ERC20.sol#159) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Mirai.constructor(address).developers (Mirai.sol#24) lacks a zero-check on :
- _developers = developers (Mirai.sol#36)
Mirai._transferBNB(address,uint256)._to (Mirai.sol#87) lacks a zero-check on :
- _to.transfer(amount) (Mirai.sol#88)
Check that the address is not zero.

Mirai.burn() (Mirai.sol#43-49) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp >= (_deployTimeStamp + 86400),Burn date not reached) (Mirai.sol#44)
Avoid relying on block.timestamp.
