Sell rights to a legacy address (e.g., Factom / FCT) for nominal USDC
- Paste the legacy chain and public address.
- Paste your private key locally — it will be encrypted in your browser with our public key.
- E‑sign the one‑page assignment.
- Submit → you receive a Pending Receipt. We then send 0.10 USDC manually and finalize your receipt.
We never receive your plaintext key. The key is encrypted client‑side with RSA‑OAEP and only the ciphertext is uploaded. Don’t proceed unless you intend to sell and relinquish control of the address contents.
