NAUT [Astronaut] Token

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

Contract ownership is not renounced (belongs to a wallet)

Low level call in Address.sendValue(address,uint256) (#300-306):
- (success) = recipient.call{value: amount}() (#304)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#366-387):
- (success,returndata) = target.call{value: weiValue}(data) (#370)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Token is deployed only at one blockchain

Contract has 4% buy tax and 3% sell tax.
Taxes are low but contract ownership is not renounced. Token has a high risk of becoming a honeypot.

Swap operations require suspiciously high gas. Contract logic is complex and may disguise some form of scam.

Average 30d PancakeSwap liquidity is low.

Average 30d number of PancakeSwap swaps is low.
