Bitcoin L2 AppChain for DePIN
Technical & Commercial FAQs
Answers to the most common questions from CTOs and founders evaluating a custom Bitcoin L2 solution for their DePIN project.
For a standard Bitcoin L2 AppChain with DePIN-specific modules, the typical timeline is 6-10 weeks. This includes 2 weeks for architecture and design, 3-5 weeks for core development and smart contract integration, and 1-3 weeks for security audits, testing, and deployment. Complex integrations (e.g., custom hardware oracles) can extend this by 2-4 weeks.
