CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Full Lifecycle Support: From initial audit and
Foundry/Hardhattesting to mainnet deployment and upgrade management viaTransparentorUUPSproxies. - Security-First: Every contract undergoes internal review against common vulnerabilities before we recommend third-party audits from firms like
CertiKorQuantstamp. - Measurable Outcomes: Typical delivery includes a 2-4 week MVP for core logic, with 99.9% uptime post-launch support and documented gas optimization reports.

Frequently Asked Questions
Common questions from CTOs and technical founders evaluating portfolio management infrastructure.
For a standard Cross-Asset Portfolio Engine deployment, we deliver a production-ready MVP in 4-6 weeks. This includes architecture design, smart contract development, off-chain indexer setup, and integration with your front-end. Complex multi-chain deployments or custom rebalancing logic may extend this to 8-10 weeks. We provide a detailed project plan with weekly milestones during the discovery phase.
