Crypto exchanges are expanding beyond digital assets as contracts tied to stocks, indexes and commodities drive a reported $778 billion boom on crypto venues. Fasanara Digital said these mainstream-asset contracts represented 23.48% of perpetual-futures (futures without an expiry date) trading volume on major digital-asset platforms in August, up sharply from 0.5% in November. The shift offers fresh evidence that crypto-market infrastructure and traditional financial markets are becoming more closely connected.
