Extend Dapp Card Store to Allow Secondary Sales




in over 262 years



6398.72 USD



Modify Agoric’s dapp-card-store to allow users to list their own cards for sale. Make the following modifications to the UI:

  • Add “My Cards” page which displays the cards owned by the user
  • Add “Marketplace” page which shows secondary sales listings
  • Current dapp page which sells cards to user directly becomes “Primary Sales”

User should be able to list their card for sale. User flow:

  1. User navigates to “My Cards” page
  2. User selects a card to list for sale
  3. User chooses the sale mechanism (currently only one - Fixed price sale)
  4. Choose price for listing in RUN
  5. Optional for user: Choose end date & time for the listing
  6. User confirms choice and creates listing
  7. User navigates to “Marketplace” page and can see all marketplace listings and filter to his/her own listing(s)


Agoric has an example dapp which allows users to purchase Baseball card NFTs directly from the application for a fixed price. The dapp instantiates a separate contract to sell these items and includes a basic front end.

For this bounty, we’d like you to extend the Dapp card store to allow holders of baseball cards to offer theirs for sale at a fixed price.
