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

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Coinfresh.constructor().msgSender (#310) lacks a zero-check on :
- _owner = msgSender (#313)
Coinfresh.changeRouterContingency(address).router (#422) lacks a zero-check on :

Contract ownership is semi-renounced (passed to a contract)

Average 30d PancakeSwap volume is less than $100. Token is either dead or inactive.

Contract has 10% buy tax and 15% sell tax.
Taxes are high (over 10%) but contract ownership is renounced.

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.

Average PancakeSwap trading volume, liqudity, number of swaps are low. Token seems to be inactive.

Token is deployed only at one blockchain

BscScan page for the token does not contain additional info: website, socials, description, etc.
