What companies are in QTUM ETF?

Could you elaborate on the composition of the QTUM ETF? Specifically, which companies are included in this exchange-traded fund? I'm interested in understanding the diversity and nature of the holdings within this ETF, as QTUM, being a blockchain-based platform, might involve a unique mix of traditional and innovative firms. Clarifying the underlying assets would help investors gauge the risk and potential return of investing in the QTUM ETF.
