Generating Stealth Addresses

This process is executed by the sender to create a stealth address for a transaction.

Steps

1. Obtain Recipient’s Meta-Address

   • Format: st:sol:<spendingPubKey><viewingPubKey>.

2. Generate Ephemeral Key Pair

   • Create a random 32-byte private key (e).

   • Compute the ephemeral public key: E = e × G.

3. Compute Shared Secret

   • Extract S (spending public key) and V (viewing public key) from the meta-address.

   • Calculate P = e × V.

   • Hash P to derive h.

   • Extract a one-byte view tag from h.

4. Derive Stealth Public Key

   • Compute R = S + (h × G).

   • The stealth address is StealthAddr = PubKey(R).

5. Return Artifacts

   • Stealth Address: StealthAddr

   • Ephemeral Public Key: E

   • View Tag: The derived view tag
