CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts for DeFi, NFTs, and enterprise applications.

We architect and deploy custom smart contracts on Ethereum, Solana, and other leading L1/L2 networks. Our process is built for security and speed, delivering audit-ready code in weeks, not months.

  • Full Lifecycle Development: From concept and architecture to deployment and maintenance.
  • Security-First: Built with OpenZeppelin standards, formal verification, and comprehensive unit testing.
  • Protocol Expertise: ERC-20, ERC-721, ERC-1155, custom DeFi logic, and cross-chain bridges.

Reduce your time-to-market and technical risk with battle-tested contracts that just work.

We focus on gas optimization, upgradeability patterns, and real-world security. Every contract undergoes peer review and is prepared for third-party audits from firms like ConsenSys Diligence or CertiK.

Technical & Commercial Details

AppChain Messaging Hub Development FAQs

Answers to common questions from CTOs and technical founders about our AppChain messaging hub development process, timelines, and guarantees.

Our standard engagement follows a fixed-scope, fixed-timeline model. From kickoff to mainnet deployment, a typical AppChain messaging hub takes 4-6 weeks. This includes 1 week for architecture design, 2-3 weeks for core development and integration, and 1 week for security review and deployment. We provide a detailed project plan with weekly milestones during scoping.
