CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your protocol.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155implementations with advanced features like vesting, staking, and governance. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators with gas-optimized logic.
- Utility Contracts: Multi-signature wallets, vesting schedules, and upgradeable proxy patterns for future-proofing.
Every contract undergoes a rigorous audit process, including internal reviews and integration with leading third-party auditors. We deliver fully documented code and a deployment package ready for mainnet launch in as little as 2-4 weeks.

Frequently Asked Questions
Answers to common technical and commercial questions about our mobile-first identity solutions.
From kickoff to production launch, a standard deployment takes 4-6 weeks. This includes requirements analysis, UI/UX design, smart contract development, PWA build, integration with your backend, and a full security audit. Complex integrations (e.g., custom biometrics, multi-chain support) may extend this to 8-10 weeks. We provide a detailed project plan with weekly milestones.
