HEDERA CONSENSUS SERVICE SPECIALISTS
Core Technical Capabilities We Deliver
We architect and deploy enterprise-grade, auditable payment systems on Hedera Consensus Service (HCS), delivering cryptographic proof of every transaction for compliance and operational excellence.
03
Enterprise-Grade Security & Key Management
Our implementations follow industry best practices for key security, including HSM integration and multi-signature schemes. We ensure your private keys are managed with the highest security standards, protecting your payment infrastructure.
04
Real-Time Payment Status & Webhooks
We build real-time monitoring dashboards and configure webhook notifications for critical payment events (e.g., consensus achieved, settlement failed). This provides instant operational visibility and enables automated downstream processes.
05
Scalable Microservice Backend Development
We develop resilient backend services in Node.js, Go, or Java that interact with HCS via the Hedera SDKs. Our architecture is designed for high throughput and horizontal scaling to handle your payment volume growth.
06
Comprehensive Technical Documentation & Handover
We deliver detailed system architecture diagrams, API specifications, and operational runbooks. Our goal is to ensure your team has full ownership and understanding of the deployed system from day one.

PROVEN FRAMEWORK
Our Implementation Methodology
We deliver auditable payment systems on Hedera Consensus Service with a structured, security-first approach that ensures predictable timelines, enterprise-grade reliability, and rapid time-to-market.
01
Architecture & Design Review
We conduct a comprehensive audit of your existing payment flows and design a custom HCS integration architecture. This includes defining immutable audit trails, data structures for consensus, and integration points with your core systems.
