Have you looked into the Ethereum ecosystem of 2021 by any chance?

Some examples:

- You can use your tokens as collateral, borrow stablecoins and pay off your mortgage while the loan pays itself off from the interest being generated by the collateral - you do not have to pay back the loan => https://alchemix.fi/

- Borrow stablecoins at 0% interest on your collateral => https://liquity.org/

- Musicians managing royalties of their work through NFTs => https://eulerbeats.com/

And there's a lot more.
