Solana options: relative wing volatility eases with Solana's 2W BF25 down 0.59 points
Solana's 2W BF25 fell 0.59 volatility points to 2.80 volatility points between the daily snapshots, reducing average 25-delta wing implied volatility relative to ATM implied volatility. Across maturities, 1M BF25 declined 0.45 volatility points to 3.03 volatility points, while 1W BF25 increased 0.18 volatility points to 2.43 volatility points. The butterfly premium therefore eased unevenly along the observable curve.
