Most developers approach XRPL event monitoring like it's a simple polling problem. They spin up a script that checks wallet balances every few minutes, maybe set up a cron job to scan for new transactions. When they need real-time updates, they build a WebSocket listener that connects directly to the ledger.
This approach breaks down fast. WebSocket connections drop. Rate limits kick in. Transaction parsing gets complex when you're dealing with DEX trades, escrow releases, and payment channel updates. The script that worked fine in development starts missing events in production.
The correct frame: XRPL event monitoring is an infrastructure problem, not a feature problem.
You need reliable delivery, retry logic, signature verification, and dead-letter queues. You need to handle 22 different event types across seven categories without your application logic becoming a mess of conditional statements. Most importantly, you need this infrastructure to work when your application scales beyond a few users.
I built XRNotify because every XRPL developer was solving the same infrastructure problem independently. The results were predictable: brittle listeners, missed events, no monitoring, and hours spent debugging webhook delivery failures instead of building product features.
The Infrastructure Layer XRPL Was Missing
XRNotify sits between the XRP Ledger and your application. It maintains persistent connections to the network, parses transaction data in real-time, and delivers structured events to your endpoints via webhooks.
The delivery mechanism uses exponential backoff retry with dead-letter queues for failed deliveries. Every payload includes HMAC-SHA256 signatures for verification. When your endpoint is down for maintenance, events queue up and deliver in order once you're back online.
The event categorization covers wallet activity, DEX operations, escrow management, payment channels, NFT transfers, network state changes, and validator updates. Instead of parsing raw XRPL transaction data, you receive structured JSON with the specific information your application needs.
Beyond Simple Notifications
The real value emerges when you consider XRNotify as part of a larger data infrastructure. Network state data flows to The Neutral Bridge for financial research. Anomaly patterns feed into H.U.N.I.E.'s intelligence layer. The same infrastructure that delivers your application webhooks also powers the circuit breaker logic in H.U.N.I.E. Sentinel.
This isn't accidental architecture. XRPL generates massive amounts of transaction data, but most of it gets processed once and discarded. XRNotify captures that data at the moment it becomes available, then routes it to multiple systems that extract different types of value.
Your application gets the specific events it needs. The research infrastructure gets comprehensive network state data. The security layer gets real-time anomaly detection. The same infrastructure investment serves multiple purposes.
Technical Implementation
The system runs on Next.js 14 with PostgreSQL for persistence and Redis for event queuing. Node.js workers handle the XRPL connections and webhook delivery. XRPL.js provides the ledger interface, but the heavy lifting happens in the retry logic and delivery infrastructure.
The webhook endpoints receive POST requests with JSON payloads. Each payload includes event metadata, transaction details, and the HMAC signature for verification. Your application validates the signature, processes the event, and returns a 200 status code. If validation fails or processing errors occur, the retry mechanism handles redelivery.
Event filtering happens at the subscription level. You specify which wallets to monitor, which event types to receive, and which endpoint should handle each category. The infrastructure handles the complexity of maintaining multiple XRPL connections, parsing different transaction types, and routing events to the correct destinations.
The Result
Developers connect their systems to XRPL events without building listener infrastructure. Applications respond to network activity in real-time without polling delays. The webhook delivery guarantees mean events reach your system even during deployment downtime or temporary outages.
This is infrastructure that works when you need it to work. No missed events, no parsing edge cases, no webhook delivery debugging at 2 AM.
