FAQ
Can your platform handle high traffic and millions of active users?
A: Yes. The backend is built on high-performance microservices architecture (Node.js/Go) with Redis caching, load balancers, and WebSocket protocols to ensure sub-second latency and seamless concurrency for massive user scale.
How are smart contracts secured against vulnerabilities?
A: All smart contracts follow strict OpenZeppelin standards, undergo rigorous unit testing (Hardhat/Foundry), and are written with reentrancy guards, flash loan defense, and access controls to withstand exploits before mainnet deployment.
Do you deliver native mobile apps for iOS and Android?
A: Yes! The Premium package includes cross-platform mobile apps (React Native / Flutter) fully responsive across iOS, Android, and Windows, featuring Web3 wallet connections (MetaMask, WalletConnect).
Will I get full ownership of the source code and admin rights?
A: Absolutely. Upon project completion, you receive 100% full ownership of all source code repository access, smart contract ownership, admin credentials, and platform documentation.
