Aster has expanded its product suite with the release of Shield Mode, a protected high-performance trading option built for advanced on-chain participants. Backed by YZi Labs, the platform continues to focus on derivatives traders who demand speed, leverage, and discretion without abandoning decentralized settlement. The update arrives as on-chain perpetual markets mature and traders seek alternatives to fully transparent execution environments.

Shield Mode integrates directly into Aster Perpetual and maintains the platform’s defining feature, access to leverage of up to 1001x. The release reflects a broader shift within decentralized finance, where infrastructure increasingly mirrors professional trading standards long associated with centralized venues.

Shield Mode And The Shift In On-Chain Trading Design

Shield Mode changes how traders open and manage positions by removing the need to place orders on a public order book. This design reduces the visibility of price levels and position sizing, which has historically exposed strategy intent in decentralized markets. Execution remains fully on-chain, preserving transparency at settlement while offering greater control at trade entry.

The platform keeps its core mechanics intact. Traders can access up to 1001x leverage on BTC and ETH, trade with zero slippage, and avoid opening fees. Shield Mode also removes closing fees and gas costs, addressing two major sources of friction for active traders. These changes improve execution efficiency and make frequent position adjustments more viable on-chain.

Earlier in mid-2025, Aster introduced Hidden Orders, allowing users to conceal order details from public view. Shield Mode builds on that release by offering a broader protected environment rather than a single order-level feature.

Fee Options And Product Integration

Aster confirmed that Shield Mode supports a flexible fee framework. Upcoming options include a commission-based structure with a fixed percentage per trade and a profit-based model where fees apply only when positions close in profit. This approach aligns trading costs with different strategies, from high-volume execution to selective directional trading.

To support adoption, all Shield Mode fees are waived through the end of the year. Incentive-led launches remain common across decentralized derivatives platforms as competition intensifies for active liquidity and experienced traders.
