Generate a Stealth Address

Generate a Stealth Address

When a user initiates a private transfer, Shady uses the recipient’s Meta-Public Key to create a unique one-time stealth address. This address is derived through elliptic curve cryptography (using Ed25519 → X25519 key exchange) to ensure the address is:

• Mathematically unlinkable to the recipient’s wallet.

• Unique for every transaction.

• Recoverable only by the intended recipient.

🔑 Meta-Key Structure

Key Type	Purpose	Example Use
View Public Key (Vpk)	Detect encrypted incoming funds	Used by scanner/AI
Spend Public Key (Spk)	Authorize transfers & claims	Used by wallet signer

🧮 Derivation:

StealthAddress = Hash(Vpk, Spk, EphemeralKey)

The sender’s wallet generates an ephemeral key for each transaction, creating a new stealth address that only the recipient’s view key can recognize.
