# Zoe Roadmap

Here's a number of features that we are planning to add in the near future to Zoe, in response to user feedback.

  1. Allow smart contracts on Zoe to calculate things in terms of labeled extents ("units", such as 3 bucks), rather than unlabeled extents (the "3" of "3 bucks"). This should reduce the number of concepts as well as protect against identification mistakes.
  2. Allow users of smart contracts to make their offer rules with any order of assays. Currently, the payout rules portion of the offer rules must be in the same order as the canonical array of assays in the smart contract.
  3. Allow smart contracts to use whatever assays the users of the smart contract contribute. Currently, smart contracts must use a specific array of assays that the smart contract returns on instantiation.
  4. Allow user and smart contracts to talk about a subset of the total assays for a particular smart contract instance. For example, in autoswap, there are three assays, two for the swappable assets and one for the liquidity token for that particular instance. We would like the users to not have to include mention of the liquidity token unless they are removing or adding liquidity.
  5. Support "multiples" in offer rules. Multiples are a way of expressing partial fulfillment of offers without having to deal with the problem of division. For instance, we may want to buy 100 shares of stock for 10 dollars each, and if we can't buy 100 shares, we're happy with as much as we can get. We want to be able to encode this kind of offer more succinctly than having to make 100 separate offers.
  6. Support "disjuncts" in offer rules. By disjuncts, we mean allowing compound offers in which we want exactly one of them to be accepted. For instance, we might want to find a good weekend activity and we're ok with buying a ticket to the museum or the concert, but not both because they will happen at the same time.
  7. Separate Zoe into two layers. One layer, doing the escrowing and actually holding the assets, is in a different Vat than the other layer, which runs the contracts.
