GTE offers both cross and isolated margin. Positions are mapped to a uint256 ‘subaccount’ key (this may be smaller in production, but will remain more than enough for a reasonable number of subaccounts). If a subaccount contains only 1 position, it’s treated as Isolated Margin. If it contains more than 1, it’s treated as Cross Margin.

Cross Margin: All open positions share the same collateral pool. The unrealized PnL and minimum margin requirements of every position are summed before checking if the total account equity is above the required threshold.

Isolated Margin: Each position has its own dedicated collateral. Only the margin and PnL related to that specific position are considered when determining if it meets the requirement.

In our smart contracts, traders can have any number of Isolated or Cross Margin positions. Traders can add and remove margin to positions in Isolated & Cross Margin accounts. Leverage can be set by admin between 3 and 50x, depending on the particular token in question. In other words, the maintenance margin is 1% for assets with 50x max leverage, and 16.7% for assets with 3x max leverage.
