EVM Cross-Chain RWA Token Standard
Frequently Asked Questions
Answers to common technical and commercial questions about developing a compliant, secure token standard for real-world assets.
A standard-compliant RWA token contract suite with basic cross-chain functionality typically takes 3-5 weeks from specification to audit-ready code. Complex implementations with multi-jurisdictional compliance logic or advanced bridging can extend to 8-12 weeks. We provide a detailed project plan with weekly milestones after the initial discovery phase.
