QR Assets, a Brazilian Crypto asset management, has established a DeFi ETF, or decentralised finance exchange-traded fund, on the Brazilian Stock Exchange. The QDFI11 DeFi ETF would monitor the Bloomberg Defi index and invest 100% of its assets in real DeFi assets. The ETF would be the first of its type, and it would provide investors with a safe way to invest in the embryonic business.
