Frequently Asked Questions
Common questions from CTOs and product leaders about building a secure, scalable IoT data stream marketplace.
We deliver a production-ready MVP in 6-10 weeks. This includes core marketplace features: data stream ingestion, tokenized access control, a basic frontend dashboard, and integration with one primary blockchain (e.g., Polygon or Arbitrum). Complexities like multi-chain support or advanced analytics modules extend the timeline, which we scope and quote for upfront.
