    FAQ

    Frequently asked questions

    Ethereum offers the largest ecosystem but higher gas costs. Polygon and Arbitrum provide lower costs. BSC offers low fees with EVM compatibility. We recommend based on your requirements and budget.

    We conduct internal security reviews and work with reputable third-party audit firms. Security audits are essential before mainnet deployment. We ensure all critical issues are fixed.

    We optimize smart contracts for gas efficiency by using efficient data structures, minimizing storage operations, and leveraging compiler optimizations. We can reduce gas costs by 30-50% through optimization.
