01 · THE PROBLEM
The starting point
Existing apps (Cesium, for instance) are overloaded with community features, unsuited to a simple payment or a loyalty programme. And no tool worked out debts, advances and remaining balances between wallets automatically.
02 · WHAT WE DID
The solution
iOS/Android app in React Native (Expo) connected to Duniter v2 (Substrate): secure twelve-word wallet, local signing, live balance, payments and collections by QR code, history over GraphQL with a local cache, automatic multi-node failover, « July Fidélité » white label, Expo EAS packaging.
03 · WHAT IT CHANGED
The results
- 01A fully self-contained mobile application
- 02Balance computed in real time (free / reserved), maximum amount detected
- 03Twelve-word key protected in the native Keystore / Keychain
