Silent Payments BIP352
summary
Cake Wallet ships a working implementation of BIP352 Silent Payments on mainnet that lets one public SP1 address receive unlinkable Taproot outputs; it does not mix funds, hide amounts, or replace coin control. Server-side work adds a new tweak index to electrum-style backends so the server returns matching outputs, amounts and txids (enabling spending) instead of requiring heavy client-only scanning. Early scans are much faster after optimizations, the feature is toggleable in-app, and Bird Pay username lookups are supported.
