# Reference assets

With DIVA Protocol, users can select virtually any metric, also referred to as "reference asset", to serve as the underlying for their derivative contracts. This includes traditional and digital asset prices, as well as non-tradeable metrics like total value locked (TVL) in DeFi, Ethereum gas price, Bitcoin hash rate, or the total crypto market cap.
