Walto

Real-time wallet tracking for the XRP Ledger — see every transaction the moment it happens.

Walto is a mobile app for tracking XRP Ledger wallets in real time. A NestJS + GraphQL backend keeps a persistent XRPL websocket connection open, watching every subscribed address and persisting new transactions as they arrive. The Expo / React Native app lets you add wallets to watch, browse their transaction history, and get notified the moment something moves — read-only, no seed phrases required.

How it works

  • Track: add any XRPL wallet address to watch — no custodial access, purely read-only monitoring.
  • Listen: the backend maintains one persistent XRPL websocket connection subscribed to every tracked address across all users.
  • Notify: the moment a transaction lands, it's persisted and pushed to your device via OneSignal, plus surfaced in-app.
