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


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

TheCorgiofPolkaBridge.random(uint256,uint256,uint256) (#167-176) uses a weak PRNG: "randomnumber = uint256(keccak256(bytes)(abi.encodePacked(block.timestamp + block.difficulty + ((uint256(keccak256(bytes)(abi.encodePacked(block.coinbase)))) / (block.timestamp)) + block.gaslimit + i + ((uint256(keccak256(bytes)(abi.encodePacked(msg.sender)))) / (block.timestamp)) + block.number))) % _to (#169-172)"
Do not use block.timestamp, now or blockhash as a source of randomness

Contract locking ether found:
Contract TheCorgiofPolkaBridge (#64-349) has payable functions:
- TheCorgiofPolkaBridge.receive() (#87)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

TheCorgiofPolkaBridge.setTransferFee(uint256) (#254-258) contains a tautology or contradiction:
- require(bool,string)(_transferFee >= 0 && _transferFee <= 100,Transfer fee is between 1 and 100.) (#255)
Fix the incorrect comparison by changing the value type or the comparison.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

TheCorgiofPolkaBridge._approve(address,address,uint256).owner (#333) shadows:
- Ownable.owner() (#36-38) (function)
Rename the local variables that shadow another component.

TheCorgiofPolkaBridge.setTransferFee(uint256) (#254-258) should emit an event for:
- transferFee = _transferFee (#256)
Emit an event for critical parameter changes.

TheCorgiofPolkaBridge._transfer(address,address,uint256) (#283-308) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(senderBalance >= amount,ERC20: transfer amount exceeds balance) (#294)
Avoid relying on block.timestamp.

TheCorgiofPolkaBridge.isContract(address) (#259-266) uses assembly
- INLINE ASM (#262-264)
Do not use evm assembly.

Additional information: link

TheCorgiofPolkaBridge._mint(address,uint256) (#309-317) is never used and should be removed
Remove unused functions.

Additional information: link

solc-0.8.0 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 TheCorgiofPolkaBridge._AMM (#68) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

TheCorgiofPolkaBridge.slitherConstructorVariables() (#64-349) uses literals with too many digits:
- burnWallet = 0x000000000000000000000000000000000000dEaD (#67)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

TheCorgiofPolkaBridge.burnWallet (#67) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

tokenContract() should be declared external:
- TheCorgiofPolkaBridge.tokenContract() (#280-282)
Use the external attribute for functions never called from the contract.
