Frequently Asked Questions
Get clear answers on timelines, costs, and technical specifics for deploying a dedicated child chain for your fashion platform.
A standard child chain for a fashion marketplace with core features (NFT minting, token transfers, royalty splits) deploys in 3-5 weeks. Complex integrations (custom loyalty tokens, multi-chain bridges, advanced analytics) can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones after the initial architecture review.
