Mirrors & Verification

As with all darknet marketplaces, multiple mirrors and proxies may circulate. Verification is critical:

Bookmark the primary onion address when you first access it.
Do not click links in posts—navigate directly to the address.
Use .onion addresses exclusively when possible.

Scam risks:

Exit scams: Marketplace operators may shut down and steal funds.
Vendor fraud: Sellers may fail to deliver or provide counterfeit goods.
Account compromise: Weak passwords or phishing can lead to account takeover.
Price volatility: Cryptocurrency price changes affect market values.

Opsec considerations:

Use Tor Browser; keep it updated; disable JavaScript.
Run Tor in a virtual machine isolated from personal data.
Never maximize your browser window.
Use unique usernames.
Assume no market is permanent.
