AppChain Customization FAQs
Technical and commercial questions from CTOs and engineering leads evaluating custom blockchain infrastructure for IoT networks.
A standard IoT AppChain deployment takes 4-6 weeks for a production-ready mainnet. This includes 1 week for architecture design and consensus selection, 2-3 weeks for core development and smart contract integration, and 1-2 weeks for security audits, testnet deployment, and final configuration. Complex integrations with existing enterprise systems or custom hardware modules can extend this timeline, which we scope and quote upfront.
