To Do

• UI performance (minor)
  • No button or page-loading should take more than 1 second.
  • e.g. issue set button in RedeemView takes more than 10 seconds because it is calling fetchAccounts fresh. That should be done once and used for all pages.
• List the YES and NO tokens on serum dex and provide liquidity (major)
  • Add the market for YES and NO tokens on serum-dex
  • Make a PR in the serum-dex-ui repo to include DEMSENYES and DEMSENNO tokens
  • Make a bot to quote on serum dex based on the prices in FTX DEMSEN tokens
  • Bonus: getting listed on Bonfida will automatically give us TradingView
• Make a button to easily provide liquidity in one step (minor)
  • Remove liquidity tab in the pools
  • Add a section below "Provide Liquidity" with a input box for the user to input how much USDC he wants to provide
  • Use half of the USDC to issue set.
  • Provide liquidity to each pool using all the newly issued tokens + the value of those tokens in USDC
• Make a button to correct mispricing (minor)
  • Create button "Correct Mispricing"
  • If YES price + NO price > 1 + fees, the button should become enabled
  • When button is pressed, the UI should inform trader how much USDC in profit he will make if he confirms the trade
  • Once confirmed, issue set using enough USDC to correct mispricing -> sell all new tokens into both pools
  • Have similar button for when pYes + pNo + fees < 1 (buy from both pools and redeem set)
• Show current position and profits (minor? to show profits need to know entry price)
  • Get entry price for the user using historical blockchain state
  • Take average price of all purchases and subtract that from current price to show profit
  • Display this in a panel in top right
• Move Redeem page contents to Exchange page (minor)
  • Move the Redeem Winner, Reedeem Set and Issue Set buttons to be below the pools in ExchangeView
• Hook up a USDC on ramp (e.g. Transak) (major)
  • Contact Transak to get the ERC20 USDC on ramp
  • Integrate this into the Exchange page
  • Write tool to automatically convert the ERC20 USDC into SPL USDC using sollet.io
