Frequently Asked Questions
Common questions from CTOs and founders about implementing a secure, compliant blockchain payment solution for real estate.
A standard deployment takes 4-8 weeks from kickoff to mainnet launch. This includes 2 weeks for smart contract development and security audit integration, 1-2 weeks for frontend integration with your platform, and 1-2 weeks for testing and compliance checks. Complex requirements like custom escrow logic or multi-signature schemes can extend the timeline, which we scope and quote for upfront.
