KEY DIFFERENTIATORS
Why Build a Custom Explorer Backend?
Off-the-shelf explorers lack the custom data, performance, and security required for production-grade applications. We build purpose-driven backends that power your unique use case.
01
Tailored Data Indexing
We configure indexers to capture and structure the exact on-chain data you need—from custom token standards to complex DeFi events—ensuring your frontend has fast, relevant data.
< 2 sec
Query Latency
100%
Data Accuracy
02
Enterprise-Grade Reliability
Deploy with confidence. Our backends are built on fault-tolerant architectures with automated failover, delivering the 24/7 uptime your users and partners demand.

Frequently Asked Questions
Get clear answers on development timelines, costs, and technical capabilities for your custom blockchain explorer backend project.
A standard deployment for a custom blockchain explorer backend takes 4-8 weeks from kickoff to production-ready delivery. This includes requirements analysis, architecture design, core development, testing, and deployment. Complex integrations (e.g., multi-chain support, advanced analytics) can extend this to 10-12 weeks. We provide a detailed project plan with milestones during the initial consultation.
