Architected for Zero-Downtime Operations
Our infrastructure is designed from the ground up for mission-critical applications where every second of downtime translates to lost revenue and user trust. We guarantee the operational resilience your business demands.
Multi-Cloud Redundancy
Deploy across AWS, Google Cloud, and bare-metal providers simultaneously. Automatic failover ensures your listeners stay online even during regional cloud outages.
Stateful Hot Standbys
Every listener cluster maintains a live, synchronized standby instance. Failover is instantaneous with zero data loss, eliminating gaps in your transaction stream.
Automated Health Monitoring & Self-Healing
Proactive system checks and automated remediation scripts detect and resolve issues before they impact service, from node failures to RPC endpoint degradation.
Zero-Downtime Upgrades & Maintenance
Rolling updates and blue-green deployments allow us to deploy security patches, protocol upgrades, and feature releases without interrupting your data flow.
Geo-Distributed Load Balancing
Intelligent traffic routing directs requests to the nearest healthy endpoint, minimizing latency and preventing any single point of failure from becoming a bottleneck.
Disaster Recovery & Incident Playbooks
Pre-defined, tested recovery procedures for catastrophic events. Our team is trained to execute rapid restoration, backed by comprehensive backups and replication.
Business Outcomes: From Infrastructure to Impact
Our high-availability listener infrastructure is engineered to deliver measurable business results, from accelerated development to fortified security. See the tangible outcomes we guarantee.
Accelerated Time-to-Market
Deploy production-ready, multi-chain event listeners in under 2 weeks, not months. Our pre-built adapters for Ethereum, Solana, and Polygon eliminate custom RPC plumbing.
Enterprise-Grade Reliability
Maintain uninterrupted data flows with our 99.9% uptime SLA for critical on-chain events. Automated failover and multi-cloud redundancy ensure zero data loss.
Substantial Cost Reduction
Cut infrastructure overhead by up to 70% versus in-house builds. Our managed service consolidates RPC nodes, indexers, and monitoring into a single predictable cost.
Scalable Data Throughput
Process millions of events per day with sub-second latency. Horizontally scalable architecture grows with your user base, handling peak loads without degradation.

Our Delivery Process: From Assessment to Handoff
We deliver high-availability blockchain infrastructure with a proven, four-phase methodology. Our process ensures zero surprises, complete transparency, and a fully operational system that meets your exact specifications and SLAs.
Phase 1: Infrastructure Assessment
We conduct a deep technical audit of your current setup and requirements. We analyze target chains, transaction volumes, and data needs to design a listener architecture that scales with your growth.
Phase 2: Architecture & Proposal
Receive a detailed technical blueprint and commercial proposal. This includes node provider selection, redundancy design, failover strategy, and a guaranteed 99.95% uptime SLA for the final system.
Phase 3: Development & Deployment
Our engineers build, configure, and deploy your custom listener infrastructure. We implement monitoring, alerting, and data validation layers, followed by rigorous load and failure testing.
Phase 4: Knowledge Transfer & Handoff
We provide complete documentation, operational runbooks, and training for your team. The system is fully handed over with ongoing support options, ensuring you have full control and understanding.
