BLKC [BlackHat] Token

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

Contract ownership is not renounced (belongs to a wallet)

ERC20Permit.constructor(string).name (#1262) shadows:
- ERC20.name() (#895-897) (function)
- IERC20Metadata.name() (#820) (function)
BlackHat.burn(address,uint256,uint8,bytes32,bytes32).owner (#1356) shadows:
- Ownable.owner() (#582-584) (function)
Rename the local variables that shadow another component.

Variable 'ECDSA.tryRecover(bytes32,bytes).r (#181)' in ECDSA.tryRecover(bytes32,bytes) (#176-205) potentially used before declaration: r = mload(uint256)(signature + 0x20) (#198)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

ERC20Permit.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (#1267-1286) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,ERC20Permit: expired deadline) (#1276)
Avoid relying on block.timestamp.

ECDSA.tryRecover(bytes32,bytes) (#176-205) uses assembly
