1. Create Order (Buyer)
Generate a private key, specify the vanity pattern you want (e.g., "dead", "0000"), set a reward in ETH, and create an order. Keep your private key safe!
2. Mine (Seller)
Copy the profanity2 command, run it on your GPU. The tool will find a salt/offset that creates an address matching the pattern.
3. Submit Offset (Seller)
Click "Submit Solution" on an open order, paste the offset/salt from profanity2, and claim your ETH reward instantly.
4. Calculate Key (Buyer)
After order is filled, use "Calculate Final Private Key" with your original key. Final key = (original + offset) mod N.
Cancel Order (Buyer)
Cancel your open order anytime to get a full refund of your ETH reward.
Claim Expired (Buyer)
If your order expires without being filled, claim your refund to get your ETH back.
Pattern Types: Leading (starts with 0x + pattern), Matching (contains pattern anywhere), Contract (CREATE2 contract address prefix)
Security: Your private key is never exposed. Elliptic curve math ensures only you can compute the final key.
