SHLND [Shiba Land] Token

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

Shibland.ensureOneTxPerBlock(address) (#921-926) uses a dangerous strict equality:
- isNewBlock = _blockNumberByAddress[addr] == 0 || _blockNumberByAddress[addr] < block.number (#922-923)
Don't use strict equality to determine if an account has enough Ether or tokens.

Contract ownership is not renounced (belongs to a wallet)

Shibland.transfer(address,uint256) (#876-902) performs a multiplication on the result of a division:
-toBurnAndToShare = _value / _burnRate (#893)
-ERC20.transfer(_to,_value - (2 * toBurnAndToShare)) (#895)
Shibland.transferFrom(address,address,uint256) (#928-953) performs a multiplication on the result of a division:
-toBurnAndToShare = _value / _burnRate (#942)
-ERC20.transferFrom(_from,_to,_value - (2 * toBurnAndToShare)) (#945)
Consider ordering multiplication before division.

Shibland.setBurnRate(uint256) (#864-866) should emit an event for:

Emit an event for critical parameter changes.

Shibland.constructor() (#839-844) uses literals with too many digits:
- _burnAddress = address(0x000000000000000000000000000000000000dEaD) (#841)
Shibland.slitherConstructorVariables() (#826-955) uses literals with too many digits:
- _initialSupply = 100000000000 * 10 ** 18 (#832)
Use: Ether suffix, Time suffix, or The scientific notation
