What it is: a mobile app that watches XRP Ledger addresses and sends push notifications for payments and security-relevant account changes. Why: on the XRPL, a common move after someone compromises a wallet is to set a Regular Key so they keep control. Most people never notice until it’s too late. I wanted an alert the moment it hits the ledger. Stack: Expo / React Native, Apollo GraphQL, a Node backend listening to the ledger, OneSignal for pushes, Firebase for analytics and crash reporting. What I learned: XRPL addresses are case-sensitive. An early bug uppercased them in the UI and showed addresses that don’t exist 🙃 Per-wallet rules (direction, minimum amount, mute) cut notification fatigue a lot Status: live on Google Play, ~10 installs, version 1.4. https://play.google.com/store/apps/details?id=com.polymita.wallettrackingapp Happy to get roasted on the UX, onboarding or positioning.   submitted by   /u/Most_Revolution_5386 [link]   [comments]
