Contract has 12% buy tax and 12% sell tax.
Taxes are suspiciously high (over 10%) and 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.

Token is deployed only at one blockchain

Unable to find whitepaper link on the website

Token is not listed at Mobula.Finance
