Volatility Surface Proofs

Definition

Volatility surface proofs represent the mathematical verification methods used to ensure the consistency and arbitrage-free nature of implied volatility surfaces within cryptocurrency derivatives markets. These proofs validate that the market prices of options across varying strikes and expirations do not permit riskless profit opportunities, maintaining the integrity of the pricing model. By systematically checking for non-negative butterfly spreads and calendar spreads, these proofs ensure that the observed volatility structure aligns with the theoretical constraints required for stable option valuation.
