At the moment, you can swap your collateral or debt using our Recipe Creator function. Using it, you can change your Aave collateral asset to an asset with a higher supply APY or you can swap your debt to an asset with a lower borrow interest rate. This requires some knowledge of using flash loans in the Recipe Creator but provides this great feature.
Our plans also include the integration of Aave v2 into the Loan Shifter. The options will include collateral and debt shifts, as well as protocol shifting options for anyone wanting to move from MakerDAO or Compound to Aave, or vice versa. This is expected to be released very soon!
