The platform is waiving gas fees and trading fees until December 31.
Decentralized perpetual exchange (Perps DEX) Aster has launched Shield Mode, a protected trading feature that allows users to execute high-leverage perpetual trades without broadcasting their positions to the market.
The new mode offers leverage of up to 1,001 times on Bitcoin (BTC) and Ether (ETH) pairs with instant execution and zero slippage while keeping orders off public order books.
Also, as part of a promotional launch running until December 31, the platform has waived all gas costs and trading fees, though trades executed in Shield Mode will not count toward Aster’s airdrop rewards program.
In June 2025, the platform introduced Hidden Orders, making it the first perpetual decentralized exchange to offer integrated hidden order functionality that conceals both price and size from other market participants.
One of blockchain technology’s fundamental characteristics is transparency; however, despite its best intentions, it has created an unexpected vulnerability for traders.
This visibility enables maximal extractable value (MEV) attacks, a practice where bots and validators profit by reordering, inserting, or censoring transactions.
Common MEV strategies include frontrunning, where traders observe pending large orders and execute their own trades first. Then, there are sandwich attacks, which place orders immediately before and after a target transaction to profit from the resulting price movement.
The problem has become serious in the DeFi space, where transparency allows strategic actors to profit from information asymmetries. Unlike traditional finance, where dark pools and private execution venues have long existed to protect large orders, most DEX trading activity can be viewed by the general public.
In its announcement on X, Aster wrote, “Shield Mode is for traders who want performance without broadcasting their next move — a protected execution mode today and an early building block for the privacy features we’re exploring with Aster Chain.”
One perk of the Shield Mode is “isolated margin for precise risk control,” allowing traders to limit potential losses to their position size while maintaining high leverage ratios.
The feature includes one-tap long and short execution with zero slippage guaranteed on supported trading pairs during launch.
This latest announcement comes as Aster is trying to establish itself as a major player in the perpetual trading market. The platform briefly overtook Hyperliquid as the largest decentralized perpetuals exchange protocol in September 2025.
Currently, it leads Hyperliquid in terms of perps volume, seeing over $4.95 billion in the last 24 hours, compared to Hyperliquid’s $3.17 billion. The 30-day perp volume transaction on Hyperliquid is over $204.35 billion, while Aster saw $219.85 billion in perp volume. Hyperliquid still leads the platform in terms of DEX volume, raking in over $6.59 billion in the past 30 days, while Aster has seen over $2.72 billion.
Aster has positioned Shield Mode as an early component of privacy features planned for its DEX.
It also stated that it will be introducing a Flexible Fee Model soon, and this model will have a fixed percentage per trade in its commission mode and a profit-and-loss (PnL) mode, which allows users to pay only when they profit.
These offers will definitely increase the platform’s users and also impact its position in the decentralized perps market.
Aster’s approach to privacy reflects a growing recognition within DeFi that pure transparency may conflict with practical trading needs, and this concern has helped to boost privacy solutions like Zcash, which experienced a major revival this year.
