The reliability of real-time data sources for Volmex, a decentralized volatility index protocol, hinges on its use of Deribit options data, processed via the Black-Scholes model to calculate 30-day implied volatility for Bitcoin (BVIV) and Ethereum (EVIV). While Volmex’s methodology mirrors the VIX, its selection of eight specific put and call options (15 and 45 days to expiration) lacks transparency, potentially impacting accuracy. Built on Ethereum and Polygon, the protocol ensures decentralized, non-custodial data feeds, enhancing trust. Integration with TradingView and partnerships with exchanges like Bitfinex bolster accessibility and liquidity. However, reliance on off-chain calculations and limited historical data may introduce risks. Continuous auditing by CertiK and Coinspect strengthens security, but users should verify data consistency independently.
