According to @PolynomialFi, the platform has introduced zero-fee perpetual futures, designated October as the final month to earn trading points, enabled multi-collateral and cross-margin risk management, and supports execution via TradingView alerts and API, as announced on Sep 30, 2025 (source: @PolynomialFi on X).

According to @dydxfoundation, the dYdX community has approved upgrading the ASTER-USD perpetual market from isolated margin to cross margin via Governance Proposal 289. Source: dYdX Foundation on X (Sep 30, 2025); Mintscan dYdX Chain Proposal 289. Under cross margin on dYdX, account equity can be shared across positions, improving capital efficiency compared with isolated margin while allowing losses in other positions to impact ASTER-USD margin health.

Traders can size ASTER-USD positions using portfolio collateral but should monitor account-level initial and maintenance margin to avoid liquidations triggered by drawdowns elsewhere.

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).
