About
The project provides combined privacy and simplicity via the following features: - Stealth Addresses: Hide payment destinations using cryptographic stealth addresses - ENS Integration: Store stealth address generation public keys in ENS records - WalletConnect: Accept payments via WalletConnect - Unlink: Private sender payments to hide transaction origin - Merchant Tools: Create stealth recipients and withdraw funds
How it's made
The Stealth Addresses are created from public information advertised by the merchant / recipient and randomness generated from each transaction. Akin to Diffie-Hellman key exchange, a Stealth Address only known to the sender and recipient is generated, with the recipient being the only party that can discover and withdraw. This provides privacy to merchants. In addition the Unlink protocol is used to conceal the sender. For example, for small political donations, even the built-in compliance in the Unlink Protocol, would not be able to reveal the actions of the sender, as the destinations are Stealth Addresses undiscoverable even upon subpoena or hack.
