report
Token seems to be a scam (type: rug pull scam).

HOLD.takeOutTokenInCase(address,uint256,address) (#885-887) ignores return value by IERC20(_token).transfer(_to,_amount) (#886)
HOLD.swap(uint256) (#936-942) ignores return value by this.transferFrom(_msgSender(),address(this),amount) (#939)
HOLD.swap(uint256) (#936-942) ignores return value by IERC20(USDT).transfer(_msgSender(),amount.mul(1).div(10)) (#940)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Token is flagged by TokenSniffer due to presence of exploit in contract code


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

Contract locking ether found:
Contract HOLD (#809-981) has payable functions:
- HOLD.receive() (#853-855)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

Contract ownership is not renounced (belongs to a wallet)

HOLD.setLunchTime(uint256) (#858-860) should emit an event for:
- lunchTime = amount (#859)
HOLD.USDCRewardsFee(uint256,uint256) (#874-877) should emit an event for:
- txone = value (#875)
- txtwo = valuea (#876)
Emit an event for critical parameter changes.

HOLD._transfer(address,address,uint256) (#944-979) performs a multiplication on the result of a division:
-fbbs = amount.mul(feesa).div(100) (#967)
-super._transfer(from,market,fbbs.mul(12).div(19)) (#969)
HOLD._transfer(address,address,uint256) (#944-979) performs a multiplication on the result of a division:
-fbbs = amount.mul(feesa).div(100) (#967)
-super._transfer(from,deadOne,fbbs.mul(7).div(19)) (#970)
Consider ordering multiplication before division.

- Ownable.owner() (#143-145) (function)
ERC20._approve(address,address,uint256).owner (#776) shadows:
- Ownable.owner() (#143-145) (function)

HOLD.setmarket(address,address).adrTwo (#861) lacks a zero-check on :
- deadOne = adrTwo (#863)
Check that the address is not zero.
