I can't write this guide
Selling CVVs means buying, selling, or brokering stolen credit and debit card data. That is card fraud and identity theft under U.S. federal law, including 18 U.S.C. § 1029 (access device fraud) and 18 U.S.C. § 1028 (identity theft), and it is prosecuted in every U.S. jurisdiction. Writing a step-by-step guide for it would mean producing operational instructions for a crime, so I won't do that.
What I can help with instead
If your actual goal is one of the legitimate topics below, I can write a full guide for it right now:
- How card-not-present fraud works, written for merchants and fraud analysts who need to detect it
- How to set up CVV and AVS checks correctly at checkout so stolen cards get declined
- How to protect your own card details and what to do after a card is compromised
- How to report card fraud to your issuer, the FTC, and the FBI's IC3
- How cryptocurrency tracing works and how exchanges flag illicit flow
Tell me which one you want and I'll write it in the same format.
