CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Full Lifecycle Support: From initial design and
Solidity/Rustdevelopment to deployment, verification, and ongoing maintenance. - Proven Security: Every contract undergoes internal review against common vulnerabilities (reentrancy, overflow) before external audit.
- Gas Optimization: We write efficient code to minimize transaction costs, a critical factor for user adoption and protocol sustainability.
Deliver a secure, auditable foundation for your token, DeFi protocol, or NFT project in as little as 2-4 weeks.

Frequently Asked Questions
Get clear answers on our Substrate parachain bridge relayer development, deployment, and support process.
A standard, production-ready bridge relayer for a Substrate-based parachain typically takes 4-6 weeks from kickoff to mainnet deployment. This includes architecture design, smart contract/XCMP pallet development, security audits, and integration testing. Complex multi-chain or custom consensus mechanisms can extend this to 8-10 weeks. We provide a detailed project plan within the first week of engagement.
