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


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


Contract ownership is not renounced (belongs to a wallet)

Grape.allowance(address,address).owner (#359) shadows:
- Ownable.owner() (#29-31) (function)
Grape._approve(address,address,uint256).owner (#459) shadows:
- Ownable.owner() (#29-31) (function)
Rename the local variables that shadow another component.

Grape.setMaster(address) (#396-400) should emit an event for:
- master = account (#398)
Emit an event for critical parameter changes.

Grape.burn(uint256) (#383-386) should emit an event for:
- _totalSupply -= amount (#385)
Grape.setNumber(uint256) (#388-390) should emit an event for:
- _theNumber = newNumber (#389)
Grape.setRemainder(uint256) (#392-394) should emit an event for:
- _theRemainder = newRemainder (#393)
Grape.rewardHolders(uint256) (#414-417) should emit an event for:
- _totalSupply += amount (#416)
Emit an event for critical parameter changes.

Ownable.constructor().msgSender (#24) lacks a zero-check on :
- _owner = msgSender (#25)
Grape.setMaster(address).account (#396) lacks a zero-check on :
- master = account (#398)
Check that the address is not zero.

Reentrancy in Grape.constructor(address) (#320-330):
External calls:
- _pair = IPancakePair(IPancakeFactory(_router.factory()).createPair(address(this),address(_router.WETH()))) (#322)
State variables written after the call(s):
- _allowances[address(_pair)][master] = ~ uint256(0) (#326)
- _balances[owner()] = _totalSupply (#324)
- _marketersAndDevs[owner()] = true (#327)
- master = owner() (#325)
Apply the check-effects-interactions pattern.

Pragma version0.8.9 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.9 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.

Variable IPancakeRouter01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#149) is too similar to IPancakeRouter01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#150)
