Testnet. Nothing here is tradeable. The market data is real and live. The option prices, Greeks and margin requirements are computed by this page from that data — they are not quotes, no counterparty stands behind them, no contract exists on any chain, and there is no order book, no settlement and no custody. Volatility for most symbols is inferred rather than observed and is labelled on every row; symbols marked unvalidated failed the validation described in the evidence page. This is a demonstration of a pricing and risk engine, not an offer to sell or a solicitation to buy any security, derivative or other instrument, and nothing on it is investment advice.

Where each volatility came from

observed Implied vol fitted to a live options market on this symbol.
partial A real options market, too few expiries to trust its shape.
extrapolated Anchored symbol, tenor outside the fitted range. Held flat, never extended.
inferred No options market. Level from this symbol's own tape times the cohort premium, shape borrowed from the nearest-volatility anchors.
unvalidated Inferred, but this symbol's volatility sits outside the donor range, where leave-one-out testing showed the method fails.
modelled Not crypto. No cohort to borrow a shape from at all.
