Hedera Consensus Service Integration

Implement enterprise-grade data integrity and immutable audit trails by integrating your applications with Hedera Consensus Service (HCS). We deliver high-throughput, fair-ordering, and finality for mission-critical logs.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect and deploy custom smart contracts for DeFi, NFTs, DAOs, and enterprise applications. Our engineers specialize in Solidity 0.8+, Rust, and Vyper, implementing OpenZeppelin standards and gas-optimized patterns from day one.

  • Security-First Process: Every contract undergoes internal audits, formal verification, and testing with Foundry/Hardhat before deployment.
  • Full-Stack Integration: We deliver contracts with frontend SDKs, ethers.js/wagmi hooks, and comprehensive documentation.
  • Measurable Outcomes: Reduce development cycles by 60%, achieve 99.9% uptime SLAs, and pass third-party audits on the first review.

Our HCS Integration Capabilities

We architect and deploy Hedera Consensus Service integrations that deliver predictable costs, sub-second finality, and enterprise-grade reliability for your data layer.

01

Custom Topic & Mirror Node Architecture

Design and deploy optimized HCS topics with dedicated mirror nodes for real-time, ordered data streams. We ensure your application logic is perfectly synchronized with the immutable ledger.

< 5 sec
Finality
24/7
