Overview

Wintip is a decentralized tipping platform on the Canton Network. Creators receive tips and sell digital products; supporters tip, send red pockets, subscribe, and swap tokens from their wallet.

The challenge

The web product moves fast. The mobile app has to keep pace with every new feature and schema change, while staying native-quality and safe for real money on both platforms.

What I built

  • The React Native app (bare CLI, TypeScript, no Expo), released to Google Play and prepared for the App Store.
  • Wallet flows for tips, red pockets, subscriptions, and multi-token swaps, mirroring the web product's logic one to one.
  • Transaction security: a transaction PIN, with biometric unlock that stands in for the PIN once it is verified.
  • A sync process with the web team — compare changes, flag anything incorrect on the web side, and port only what is right for mobile.

Results

A native app that keeps feature parity with the web platform without inheriting its mistakes, and a release process the team can repeat for every update.
