The day across the three live Derivasys markets.
The major-coin options complex retains a marked gap between ETH and SOL on one-week implied volatility versus seven-day realised volatility.
This is a comparison, not a pooled surface: each asset keeps its own forwards, expiries, SVI fit and realised-volatility history.
Cross-sectional thesis
Where the complex is diverging.
One-week ATM IV level dispersion is compressing, at +14.87 vol pts; daily one-week ATM IV changes span +7.42 vol pts across the complex.
ETH screens richest and SOL cheapest on one-week implied volatility versus seven-day realised volatility, with a 13.91-point cross-sectional range.

Completed-session cross-asset context
Crypto volatility against VIX and SPX.
The benchmark comparison is separately timestamped to the latest completed US session; it does not replace the intraday crypto surface cutoffs above.
BTC and ETH and SOL 30-day implied volatility remained 2.3–3.5 times VIX, while short-window equity correlations remained low.

A derived publication with no duplicated market data.
The report is assembled at request time from the immutable BTC, ETH and SOL daily-report artifacts for the same UTC report date. It is omitted unless all three exist. Cross-asset averages are descriptive and equal-weighted; no attempt is made to combine distinct volatility surfaces into a single fit.
