Tokenised stocks and ETFs

Hello, I have been wondering for the last few days if it’s possible to buy stocks or ETFs using crypto. I initially though that, just like there are stable coins pegged to fiat currencies, there would be coins pegged to a specific crypto or especially etf. Yet I wasn’t able to find anything, until I stumbled soon this entry on coin market cap: https://coinmarketcap.com/currencies/nvidia-tokenized-stock-ftx/ Obviously FTX has gone bust, but I was wondering if someone was still offering this kind of service, and if not why. Thanks in advance
