Jun 1, 2025June 2025: Delivered privacy-first networking and reliability enhancements in cake_wallet. Implemented built-in Tor support that routes all network traffic through Tor and refactored modules for Tor proxying; introduced Tor endpoints for fiat-api and service-api to create a more private and robust networking stack. Enhanced branding and readability by embedding the app logo in QR codes and increasing the error correction level to High. Improved Monero wallet stability by ensuring transaction data is cached reliably post-commit and by returning safe defaults when wallet data is unavailable to prevent crashes. These changes reduce crash risk, improve privacy and branding, and lay groundwork for further privacy features.
