Frequently Asked Questions

How do you ensure smart contract security?

We follow security best practices including formal verification, extensive testing (unit, integration, fork tests), multiple audit rounds, static analysis tools (Slither, Mythril), and bug bounty programs. We also implement upgrade patterns and circuit breakers for emergency situations.

Which blockchain should I choose for my project?

The choice depends on your requirements. Ethereum offers the best security and ecosystem. Polygon provides lower costs with EVM compatibility. Solana offers high throughput. BSC is cost-effective with large user base. We'll recommend based on your specific needs during consultation.

How much does gas optimization save?

Our gas optimization techniques typically reduce costs by 30-50%. This includes using efficient data structures, minimizing storage operations, batch processing, and implementing ERC standards correctly. Savings compound significantly with high transaction volumes.

Do you provide ongoing support after launch?

Yes, we offer comprehensive post-launch support including smart contract monitoring, security updates, community management, tokenomics adjustments, and feature enhancements. We also provide incident response and emergency procedures.
