overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Custom Logic: From
ERC-20/721/1155tokens to complex DeFi protocols and DAO governance systems. - Full Lifecycle: Development, testing (
Hardhat/Foundry), deployment, and post-launch maintenance. - Guaranteed Outcomes: 99.9% uptime SLA for critical functions and 2-week MVP delivery for standard token contracts.
We don't just write code; we engineer trust. Every contract is designed for gas efficiency, upgradeability, and long-term security, ensuring your project's foundation is unshakeable.

TANGIBLE RESULTS
Business Outcomes for Your Project
Our Hedera Consensus Service bridge design delivers measurable infrastructure advantages, translating directly into faster time-to-market, lower operational costs, and enhanced trust for your application.
01
Sub-Second Finality & Predictable Costs
Leverage HCS's native asynchronous Byzantine Fault Tolerance (aBFT) consensus for transaction finality in under 2 seconds. Eliminate gas fee volatility with HCS's fixed, predictable transaction fees, enabling reliable cost forecasting for your business model.

Frequently Asked Questions
Common questions from CTOs and technical leads about our HCS bridge development service, timelines, security, and support.
Our process follows a structured 4-phase methodology: 1) Discovery & Architecture (1-2 weeks): We analyze your use case, design the bridge architecture, and finalize smart contract specs. 2) Core Development (3-5 weeks): We build the HCS listener, consensus verification logic, and target chain relay/executor. 3) Security & Testing (2-3 weeks): We conduct internal audits, unit/integration testing, and a testnet deployment. 4) Deployment & Handoff (1 week): We deploy to mainnet, provide documentation, and conduct knowledge transfer. We provide weekly sprint demos and maintain a shared Jira board for full transparency.
