Collateral will be flagged for liquidation once your health factor drops to 1
Select the Synthetic you want to mint. I want to mint some baoUSD with my supplied collateral.
Put in the desired amount you wish to mint out of the amount that's available to you from your supplied collateral, then click Mint. This will bring up a transaction and click confirm in your wallet.
When the transaction is complete, your debt limit will have decreased, and the assets you minted will now be in your wallet. Your health factor will also have been recalculated.
Make sure to keep an eye on your health factor so you are not liquidated!
