Market Surface
Every Masayume Window is priced by a live order book on DreamDEX — resting bids and asks, not a volatility model. The ticket uses one number, the top of that book; here you can read the whole structure back: how deep each side is, what a bigger stake would really pay, and how every live expiry of the asset is priced right now. Every figure is the chain's own book; nothing is estimated.
