Stealth addresses

Stealth addresses reduce direct linkability between a recipient’s known identity and a payment address.

Concept

A payer can derive a one-time address for a recipient using an ephemeral key exchange. The recipient can later detect or recover ownership with the appropriate private material.

Veilpay implementation direction

The repo includes stealth-address utilities using ECDH-style shared secret derivation and deterministic address generation.

Security expectations

• Generate fresh ephemeral keys per payment.
• Never log shared secrets.
• Never expose recipient private keys.
• Keep directory and key-publication flows explicit.
• Treat stealth addresses as a privacy improvement, not a full private payment system by themselves.
