I built XRNotify because every XRPL developer I talked to was solving the same problem over and over: monitoring wallet activity and transaction events on the XRP Ledger. Everyone was rolling their own listener infrastructure from scratch, dealing with connection drops, implementing retry logic, and handling edge cases that only surface in production.
The result was predictable: brittle systems with no monitoring, failed event deliveries going unnoticed, and developers spending time on infrastructure instead of building features.
The Technical Problem
The XRP Ledger is event-driven by design. Wallets receive payments, escrows execute, trust lines change, NFTs transfer. Applications need to react to these events in real-time, but the XRPL WebSocket connection requires constant babysitting.
Connection drops happen. Network partitions occur. Your application might miss critical events, and you won't know until users start complaining. Building reliable listener infrastructure means handling reconnection logic, maintaining state across restarts, implementing exponential backoff, and creating monitoring systems to catch failures.
Most developers skip these details initially, then spend months retrofitting reliability into systems that were never designed for it.
Architecture Decisions
XRNotify handles the entire pipeline from XRPL event detection to webhook delivery. The architecture separates concerns cleanly:
Event Detection Layer: Node.js workers maintain persistent connections to XRPL nodes, handling reconnections and state reconciliation automatically. When connections drop, workers detect the gap and backfill missed events from ledger history.
Event Processing: PostgreSQL stores event data with proper indexing for wallet lookups and historical queries. Redis handles the delivery queue, tracking retry attempts and managing exponential backoff timing.
Delivery Infrastructure: The webhook delivery system implements enterprise-grade reliability patterns. Failed deliveries trigger exponential backoff retry (1s, 2s, 4s, 8s, up to 256s intervals). After exhausting retries, events move to a dead-letter queue for manual investigation.
Every webhook payload includes HMAC-SHA256 signatures for verification. Developers can trust that webhook calls originated from XRNotify and haven't been tampered with in transit.
Event Categories and Types
XRNotify monitors 22+ event types across 7 categories: payments, escrows, checks, NFTs, DEX activity, trust lines, and account settings. Each event type captures the specific data developers need without requiring them to parse raw XRPL transaction formats.
For example, a payment event includes sender, recipient, amount, currency, destination tag, and memo fields. An escrow creation event includes the escrow sequence, destination, amount, condition hash, and execution timeframe.
Ecosystem Integration
XRNotify serves as the nervous system for the broader Jonomor ecosystem. Network state data flows to The Neutral Bridge, where it supports financial infrastructure research and cross-chain analytics.
Anomaly patterns detected in transaction flows feed into H.U.N.I.E.'s intelligence layer, helping identify unusual network behavior or potential security issues. XRNotify also powers the circuit breaker mechanism in H.U.N.I.E. Sentinel, automatically triggering protective measures when transaction patterns indicate potential threats.
This integration creates value beyond simple webhook delivery. The same infrastructure that powers your application's event handling contributes to broader network intelligence and security research.
Getting Started
XRNotify eliminates the infrastructure overhead of XRPL event monitoring. Instead of building and maintaining your own listener infrastructure, you configure webhook endpoints and start receiving events immediately.
The platform handles all the reliability concerns: retry logic, failure monitoring, signature verification, and delivery guarantees. You focus on building features, not babysitting WebSocket connections.
