   - Dynamic refund: currently, users set their own refund percent, but depending on the state of the mempool and blockspace auction, they may want a lower or higher refund percent. A SUAPP could simulate a user's trade, query L1 state to get pool and token information, and use this to reason about what refund % to use on that user’s bundle.
   - Dynamic hint: one of the open research questions around programmable privacy is where the privacy efficiency lies. An example of this, relevant to MEV-Share, is as follows: given a Uniswap L1 trade, how much information should be revealed? A $10 trade most likely can leak the entire trade details because it would be better to batch, but a very large trade has a risk of being probabilistically front-run; therefore, it should leak less information, or at least that is one possibility.
