Market structure
What a Bitcoin options volatility surface shows.
A Bitcoin options volatility surface maps BTC implied volatility across strike or moneyness and time to expiry. Each expiry contributes a smile; connecting calibrated smiles creates the term structure used to compare short-dated event risk with longer-dated volatility.
Compare the market's central volatility level across standard BTC tenors.
Measure 25-delta call volatility minus 25-delta put volatility to read directional skew.
Measure average 25-delta wing volatility minus ATM volatility to read smile convexity.
Inspect a smooth total-variance parameterisation together with its source quotes and residual state.

Cross-asset context
Move between Bitcoin, Ethereum, and Solana surfaces.
Seven crypto options markets are live in Derivasys. Use the same SVI, tenor, skew, convexity and diagnostic framework for each asset, then compare their volatility regimes without treating one surface as a proxy for another.
