Aster Perps DEX has launched Shield Mode, allowing the opening of high-leverage perpetual positions with a 'protected execution' mechanism, enabling users to trade without exposing their positions to the market.
The new feature targets the weakness of 'excessive transparency' in DeFi, where orders and positions are easily tracked for MEV exploitation. Shield Mode promises instant order matching, no slippage on BTC and ETH pairs, while running free gas and transaction fee promotions until December 31.
MAIN CONTENT
Shield Mode makes perpetual trading 'more discreet', not revealing positions on the public order book.
Supports a maximum leverage of 1.001x for the BTC/ETH pair, instant order matching, and commits to 0 slippage during the launch phase.
Free gas and transaction fees until 31/12, but Shield Mode orders are not counted towards Aster's airdrop program.
Shield Mode allows high leverage perpetual trading without revealing positions.
Shield Mode is a protective execution mode on Aster, allowing high leverage perpetual orders without exposing positions to the market, while supporting instant order matching and 0 slippage during the launch phase.
With Shield Mode, Aster states that users can trade Bitcoin (BTC) and Ether (ETH) with a maximum leverage of 1.001x. The core difference is that positions are not posted to the public order book, aimed at reducing the potential for tracking and exploitation by MEV strategies.
During the promotional launch lasting until 31/12, the platform waives all gas and transaction fees. However, transactions executed in Shield Mode will not count towards Aster's airdrop reward program, meaning users need to consider prioritizing 'hidden orders' or accumulating reward points.
From a derivatives tracking perspective, analytical tools on BingX can assist users in checking market contexts such as price volatility, liquidity, and trading sentiment before using high leverage, helping to plan risk more tightly.
On-chain transparency creates opportunities for MEV and order attack strategies.
Transparency is a core characteristic of blockchain, but in DeFi trading, the ability to observe orders and transactions can lead to MEV, where bots/validators reorder or insert transactions for profit.
MEV (maximal extractable value) often arises when pending transaction data is observed and exploited. Common strategies include 'frontrunning', when a bot sees a large order and enters before to benefit from price movement; and 'sandwich attack', when a bot places orders before and after the target transaction to profit from short-term price swings.
The issue becomes serious in DeFi because most activity on DEX can be publicly tracked, creating real-time information asymmetry. In traditional finance, mechanisms like dark pools or private order matching channels have long existed to protect large orders, while DEX often lacks a similar 'execution anonymity' layer.
Aster views privacy as a competitive advantage in the perp market
Aster positions Shield Mode as a step towards building future privacy features, while also adding a separate margin mechanism to control risk when trading with high leverage.
In the announcement on X, Aster emphasizes that Shield Mode targets traders seeking performance without 'broadcasting' their next move, and sees this as the first step towards the privacy features being explored with Aster Chain.
Shield Mode is for traders seeking performance without broadcasting their next move; this is the protected execution mode today and an early stepping stone for the privacy features we are exploring with Aster Chain.

Another highlight is 'isolated margin' for more precise risk control, allowing potential losses to be limited within the margin scope of the position, even while still using high leverage ratios. Aster also promotes one-tap long/short operations and commits to 0 slippage on supported pairs during the launch phase.
This effort occurs in the context of Aster wanting to strengthen its position in the perpetual segment. The platform is reported to have temporarily surpassed Hyperliquid to become the largest perp DEX in September 2025, indicating that the competition for 'order matching experience' and 'trader protection' is becoming a crucial battleground.
Perp volume and the race with Hyperliquid according to DeFiLlama data
DeFiLlama shows that Aster is leading over Hyperliquid in 24-hour and 30-day perp volume, although Hyperliquid still leads in 30-day DEX volume, reflecting the difference between perp activity and total DEX transactions.
Currently, Aster is reported to be leading Hyperliquid in perpetual volume over 24 hours: over $4.95 billion compared to $3.17 billion. In the 30-day frame, Hyperliquid has over $204.35 billion in perp volume, while Aster reaches $219.85 billion.
However, Hyperliquid still leads in DEX volume over the past 30 days with over $6.59 billion, while Aster is at over $2.72 billion. This shows that Aster is strong in perp products, while Hyperliquid has an advantage in total DEX transactions, at least according to the metrics being compiled by DeFiLlama.
Hidden Orders and Aster's privacy roadmap
Shield Mode continues Aster's privacy strategy after Hidden Orders, while the platform reveals a Flexible Fee Model with two fee calculation mechanisms: fixed rate or based on PnL.
In June 2025, Aster introduced Hidden Orders and described it as the first perpetual DEX integrating hidden orders, concealing both price levels and order sizes from other market participants. Compared to Shield Mode (focused on 'protected execution'), Hidden Orders emphasize reducing the visibility signal of orders.
Aster also stated that it will soon implement a Flexible Fee Model, including a fixed rate fee for each transaction and a profit/loss (PnL) model, where users only pay fees when they make a profit. If executed correctly, these mechanisms can significantly impact trader behavior and Aster's position in the decentralized perps market.
In the broader picture, Aster's approach reflects the DeFi trend acknowledging that 'absolute transparency' sometimes contradicts real trading needs. This concern also contributes to pushing privacy-focused solutions and rekindling the 'privacy' theme in crypto this year.
Frequently asked questions
What is Shield Mode on Aster?
Shield Mode is a perpetual trading mode with 'protected execution', allowing high leverage positions without exposing them to the public order book, while supporting instant order matching and committing to 0 slippage on supported pairs during the launch phase.
Why are traders concerned about the transparency of DEX?
Because orders and transactions can be observed for MEV exploitation, such as frontrunning or sandwich attacks, where bots/validators reorder or insert transactions to profit from price movements and information asymmetry.
Are Shield Mode transactions counted towards Aster's airdrop?
No. Aster clearly states that orders executed in Shield Mode will not be counted towards the airdrop reward program, even though the platform is currently waiving gas and transaction fees during the promotional period until 31/12.
How is Hidden Orders different from Shield Mode?
Hidden Orders focus on concealing prices and order sizes from market participants, while Shield Mode emphasizes protective execution mechanisms for high leverage trading without 'broadcasting' positions to the market.
What risks does 1.001x leverage carry?
Extremely high leverage can cause positions to be liquidated very quickly with small price movements. Although Aster mentions isolated margin to limit risk based on margin scale, users still need to manage capital and entry points tightly.
