According to @dydxfoundation, the dYdX community approved upgrading the 2Z-USD and ZEC-USD markets from isolated margin to cross margin, indicating a governance vote passed for these perpetual markets. Source: dYdX Foundation post on X dated Oct 7, 2025; Mintscan Proposal 293. Cross margin on dYdX pools collateral and unrealized PnL across positions, with liquidation determined at the portfolio level, changing effective leverage and risk management parameters for active traders. Source: dYdX documentation on cross versus isolated margin. Traders in ZEC-USD perps should recheck margin mode, risk limits, and available leverage because moving to cross margin alters shared collateral, available margin, and liquidation thresholds on the venue.
