According to @dydxfoundation, an on-chain governance vote is live to upgrade the ASTER-USD market on the dYdX Chain from isolated margin to cross margin under Proposal 289, enabling the community to decide the market’s margin mode change (source: https://twitter.com/dydxfoundation/status/1971660431245890047; source: https://www.mintscan.io/dydx/proposals/289). In dYdX cross margin, positions share collateral and margin is computed on total portfolio equity, whereas isolated margin confines collateral and risk to a single position or market, a structural difference that directly impacts margin utilization and liquidation calculations for traders (source: https://docs.dydx.trade/). If approved, ASTER-USD would adopt cross margin at the market level on dYdX, so traders should review current risk parameters, leverage constraints, and liquidation thresholds as defined by the protocol’s risk engine and monitor the proposal’s on-chain status for execution details (source: https://docs.dydx.trade/; source: https://www.mintscan.io/dydx/proposals/289).
