Future Swap

From DeFiChain-Wiki

Future Swap


after the introduction of stock tokens, they were traded with a premium. The prices on the DEX were higher than the prices from the oracle. To fight this premium (but also a possible discount) the future swaps were introduced with DFIP-2203-A.


This swap is executed once a week (every 7*2880 blocks). You can buy for + 5% of the oracle price or sell for -5% of the oracle price, even if the Price is higher/lower than that 5%. Buy or sell means swapping to/from DUSD.


On defiscan.live you can find a countdown to the next future swap block via the link


In the desktop wallet you can check the next future swap block using the command getfutureswapblock

To quickly check for the current premium of the stock tokens you can use the dStocks Quickcheck page at


On defichain analytics you can also follow the premium over time in a chart



With this measure the price of the dTokens can be held in a +-5% corridor. In case of a higher premium or discount it can get arbitraged. For the case of a premium the following trade can be done

  • Mint a dToken using a vault (take a loan)
  • The collateralization ratio gets calculated using the oracle price (real price without premium)
  • Sell the minted dToken on the DEX (swap to DUSD)
  • Because of the premium, you get extra DUSD
  • Do a future swap using the received DUSD to buy the dToken back paying the oracle price (cheaper because it's without premium)
  • When the future Swap gets executed you will receive more dToken than you minted
  • The loan (minted dToken) can be paid back and the additional dToken will stay in the wallet as a profit
