Does B3 offer crypto exchange-traded funds in Brazil?

As a keen observer of the cryptocurrency and financial markets, I'm curious to know if Brazil's sole securities trading platform, B3, has ventured into the realm of crypto exchange-traded funds (ETFs). Given the recent advancements in Brazil's crypto market, especially with Bitcoin acting as a strong alternative to the Brazilian real, and the promising signs of mass adoption in 2021, I'm wondering if B3 has capitalized on this opportunity by offering crypto ETFs to its investors. Given B3's plans to enter the crypto market in 2022, it would be interesting to know if crypto ETFs are part of the offering, providing exposure to either single cryptocurrencies like Bitcoin or a basket of different cryptocurrencies. Such offerings could potentially provide investors with a convenient and regulated way to access the crypto market through a traditional exchange platform.
