This would be great

Even better would be the possibility of purchasing aEURS (EURS in Aave), like you can already purchase aUSDT or aUSDC to have in your fund.

Would love to have EUR denomination too =)

The UI already provides an option to display a fund's performance in EUR, but not investing in EUR, nor calculating the performance fee in EUR.

My preference would be EURS, since it should be the most easily accessible for retail investors (at least once Stasis finish their internal migration and speed up the KYC process). In theory you can get it 1:1 EUR (fiat) to EURS (ERC-20) via their app.

As far as I can tell, Paraswap already supports Curve routing via the EURS-sEUR pool, so fund managers should be able to use that to trade EURS into most other ERC-20 assets.

(Although it should be doublechecked whether their 'MultiPath' doesn't incur too much slippage when having to do multiple steps.)
