It’s an interesting idea but it would require some very significant changes to the protocol and contracts to allow paying interest in WELL:
- The WELL would have to be sold to the token you are repaying, because the interest gets paid to lenders in the token you are borrowing.
- As a borrower, you could actually do this yourself right before you repaid the loan if you wanted to use the WELL in your wallet to effectively pay the interest
There might be a way to simply automate this using a tool like Gelato (live on Moonbeam) or OAK network (coming early next year) as a 2 step process.
