Backend, indexing, and data pipelines for production

APIs, custom indexers, and event-driven pipelines that turn blockchain activity into usable operational data. Built for reliability, traceability, and production operations on EVM and XRPL.

What you get

Backend and indexing infrastructure turns blockchain events into operational reality. We deliver production-grade systems that handle data reliably at scale.

This is the layer most teams underestimate and where production systems often break.

Backend services & APIs

+

Build service layers that orchestrate workflows and integrate with your stack. Output: APIs, service boundaries, and operational tooling.

Custom indexing

+

Index smart contract and XRPL activity into queryable datasets. Output: indexers tailored to your schema, use cases, and reporting needs.

Event-driven pipelines

+

Transform, enrich, and route events across systems reliably. Output: pipelines with retries, idempotency, and clear failure handling.

Data integrity & consistency checks

+

Detect gaps, duplicates, and mismatches across systems. Output: consistency checks and alerting around critical business invariants.

Reporting outputs

+

Make data usable for ops, finance, and product teams. Output: exports, dashboards-ready tables, and audit-friendly outputs.

Observability & production hardening

+

Make systems measurable and debuggable under load. Output: metrics, logs, alerts, and runbooks for live operations.
