$METAZ [METAZ] 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)

Contract ticker ($METAZ) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

METAZ.updateFee(uint256,uint256,uint256) (#636-644) should emit an event for:
- _TAX_FEE = _txFee * 100 (#638)
- _GAME_FEE = _gameFee * 100 (#639)
- _MARKETING_FEE = _marketingFee * 100 (#640)
- ORIG_TAX_FEE = _TAX_FEE (#641)
- ORIG_GAME_FEE = _GAME_FEE (#642)
- ORIG_MARKETING_FEE = _MARKETING_FEE (#643)
Emit an event for critical parameter changes.
