CBDC Sandbox Development FAQs
Answers to the most common questions from central banks, financial institutions, and technology partners exploring CBDC sandbox development with Chainscore Labs.
A production-ready CBDC sandbox environment is typically deployed in 4-6 weeks. This includes architecture design, smart contract development, wallet/API integration, and initial testing. For more complex multi-currency or cross-border pilots, the timeline extends to 8-12 weeks. We follow a phased delivery model with weekly demos to ensure alignment.
