PANTHER-LP [PantherSwap LPs] Token

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

PantherPair._update(uint256,uint256,uint112,uint112) (#368-381) uses a weak PRNG: "blockTimestamp = uint32(block.timestamp % 2 ** 32) (#370)"
Do not use block.timestamp, now or blockhash as a source of randomness

PantherPair._safeTransfer(address,address,uint256) (#339-342) uses a dangerous strict equality:
- require(bool,string)(success && (data.length == 0 || abi.decode(data,(bool))),Panther: TRANSFER_FAILED) (#341)
PantherPair.mint(address) (#405-426) uses a dangerous strict equality:
- _totalSupply == 0 (#414)
Don't use strict equality to determine if an account has enough Ether or tokens.

Low level call in PantherPair._safeTransfer(address,address,uint256) (#339-342):
- (success,data) = token.call(abi.encodeWithSelector(SELECTOR,to,value)) (#340)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable PantherPair.swap(uint256,uint256,address,bytes).balance0Adjusted (#475) is too similar to PantherPair.swap(uint256,uint256,address,bytes).balance1Adjusted (#476)
Variable PantherPair.price0CumulativeLast (#321) is too similar to PantherPair.price1CumulativeLast (#322)
Prevent variables from having similar names.

Contract ticker (PANTHER-LP) 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.
