Aster, a leading on-chain trading platform supported by YZi Labs, introduced Shield Mode on December 15, 2025. This new trading mode integrates into Aster Perpetual, offering experienced traders discreet access to high-leverage positions—up to 1001x—while eliminating fees and gas costs through year-end. Shield Mode addresses transparency challenges inherent in decentralized markets by protecting users’ trading intentions without compromising performance.

Shield Mode: Enhancing Discretion and Efficiency in On-Chain Trading

Building on its 1001x leverage product and the earlier Hidden Orders feature introduced in mid-2025, Aster’s Shield Mode provides traders a more secure and streamlined experience. Unlike prior interaction with a public order book, Shield Mode consolidates position management and leverage trading within a single interface, removing the need for cross-chain activity or frequent transaction signing.

Core attributes include zero slippage and elimination of both opening and closing fees. Most notably, Shield Mode removes gas costs entirely, significantly accelerating trade execution and lowering expenses for high-frequency or professional traders. These benefits are available without charge until December 31, 2025, encouraging rapid adoption among on-chain perpetual trading participants.

Flexible Fee Options to Align with Diverse Trading Strategies

Later this year, Aster plans to enable users to choose between two fee models tailored to individual trading styles. Commission Mode will impose a fixed percentage fee per trade, suited for steady, high-volume traders seeking predictable costs. Alternatively, PnL Mode will apply fees only on profitable trades, aligning costs with trader success.

Leonard, Aster’s CEO, remarked, “Shield Mode reflects our commitment to giving traders high performance along with control and privacy, so they don’t have to reveal their strategies on a fully transparent chain.” This philosophy guides the platform’s design to balance leverage, speed, and discretion.

Advancing On-Chain Trading Ecosystems

Shield Mode represents a foundational step in Aster’s roadmap toward establishing a unified on-chain trading ecosystem, including the forthcoming launch of the Aster Chain. Beyond improved privacy and fee savings, Shield Mode streamlines workflows by eliminating fragmented processes like cross-chain switching or repetitive confirmations.

In addition to Shield Mode, Aster supports capital efficiency measures such as its Trade & Earn program and ecosystem expansion initiatives like Rocket Launch, which connects traders with liquidity opportunities. A multi-stage global airdrop and incentive schemes are also ongoing to foster community growth.

With up to 1001x leverage, no slippage, waived fees until year-end, and full protection of trading intent, Shield Mode is shaping a transformative trading solution tailored for the next generation of decentralized finance participants.

Shield: Market Outlook

By removing typical fee structures and gas costs, Shield Mode directly addresses key pain points for on-chain traders. Its high leverage, coupled with enhanced privacy features, is poised to attract sophisticated market participants who value both performance and discretion. As 2025 closes, industry observers anticipate robust uptake, potentially influencing broader trends in on-chain perpetual trading platforms. Shield Mode thus marks a pivotal innovation that could recalibrate expectations around cost, speed, and confidentiality in decentralized trading.
