Farm

The Farm page displays operations related to liquidity provision, short position creation and earning LP and sLP token staking rewards.

In order to create a short position, you need to lock collateral assets to Mirror Protocol, and mint new mAssets. Unlike Borrow positions, newly minted assets are immediately sold at Terraswap price for UST. UST returned for shorting mAssets will be locked for a defined lock_period. To close your short position, you must first hold shorted amount of mAssets. These mAssets will be burned to return your locked collateral.

where Annual MIR Short Reward\text{Annual MIR Short Reward} is the amount distributed to the corresponding mAsset's short staking pool per year, MIR Price\text{MIR Price} is the Terraswap Price of MIR token denominated in UST, Short Token Amount\text{Short Token Amount} is the number of mAssets sold from all short position creation, and Price\text{Price} is the Terraswap price of this mAsset token denominated in UST.
