Oasis Multiply provides a set of new features on top of Oasis Borrow. When you use Oasis Multiply you get a new dedicated interface for a Multiply position, showing you Buying Power, Net Value, Multiple number and more information in the comparison screen. This information is only applicable in a Multiply position and will help you to better manage your position.
In the first image above you see a traditional Borrow Vault, in the second image the same Vault was changed to Multiply.
With a multiply Vault you get the ability to perform multiply actions, which use flashloans to make the trades, deposits and withdrawals of the extra collateral all in one transaction. These multiply actions have a fee of 0.2% of the size of the trade that takes place in each transaction. If a transaction is a Multiply action the fee will be clearly shown in the order summary screen.
Under the hood Multiply and Borrow are the same Maker Vaults so you can use your Multiply position to deposit, borrow and generate Dai. These actions are available under the “Other Actions” tab, and they are free as always.
Just note: a different wording is used when it is connected to Multiply - "Deposit Dai" for instance is the same as "payback". "Withdraw Dai" is "generate Dai".
Multiply Vaults also enjoy a feature that allows you to close your positions instantly to either collateral or Dai without the need for any Dai or collateral in your wallet. This Multiply actions will use a flashloan and sell all collateral needed to payback all outstanding debt. If you choose to close to Dai all collateral will be sold and Dai will be sent to the wallet. Otherwise you will keep the remaining collateral after paying all outstanding debt.
Now you know you can enjoy a more complete set of features when using Multiply to manage your Vaults. You can learn how to start here.
If you have upgraded your Borrow Vault to a Multiply Vault in the Oasis UI and would like to swap it back, it can be done with ease. You will need to email email@example.com stating your wallet address and Vault ID you would like to swap back. The support team may ask for additional information to prove you own the Vault, and it can take up to 24 hours (longer at weekends) to change it.
