Aster introduces Shield Mode, providing on-chain traders with a secure and efficient trading model.

Georgetown, British Virgin Islands, December 15, 2025 – Aster, the high-performance, privacy-focused on-chain trading platform powered by YZi Labs, today announced the official launch of Shield Mode. This new protected trading mode is directly integrated into Aster Perpetual, delivering up to 1001x leverage in a faster, more secure, and more flexible on-chain trading experience.

Shield Mode is a significant milestone in Aster’s mission to build the next-generation on-chain trading platform, designed to serve advanced traders while addressing the challenges exchanges face in a fully transparent on-chain market.

Aster CEO Leonard stated, "Shield Mode embodies our core belief that the future of on-chain trading is not just about leverage or speed, but also about control, privacy, and protection. We are building a trading platform that allows traders to perform at their highest level without having to disclose their strategies to the market."

The Evolution of On-Chain Transactions: From 1001x to Shield Mode

Aster's 1001x product is renowned for pushing the limits of on-chain perpetual contract trading, offering up to 1001x leverage, zero slippage, no entry fees, and fully on-chain settlement. As on-chain trading infrastructure matures, traders are increasingly aware of the trade-offs that come with complete transparency—especially the risk that their trading strategies and intentions may be exposed to the market.

In mid-2025, Aster launched Hidden Orders on Aster Perpetual, allowing traders to keep order prices and quantities hidden from the public order book while maintaining deep liquidity. This is an important step towards providing greater privacy and autonomy to on-chain traders.

Shield Mode takes this a step further, introducing a more comprehensive protected trading mode that combines high leverage with stronger protection of trading intent, as well as a smoother and more controllable trading experience.

Shield Mode: A brand new trading mode on Aster

Shield Mode is a brand-new trading mode built directly into Aster Perpetual, integrating the complete 1001x trading experience into a single interface and account system.

This model simplifies the process for traders to establish and manage long or short positions by eliminating interaction with the public order book, while enabling high-leverage trading to proceed seamlessly without cross-chain switching, fragmented workflows, or frequent on-chain transaction signing.

The core features of the Aster 1001x trading model remain intact, including up to 1001x leverage for BTC and ETH, zero slippage, and no entry fees. Shield Mode further enhances trading efficiency by eliminating closing fees, completely eliminating gas costs, and accelerating trade execution. These improvements collectively set a new benchmark for high-performance, low-cost on-chain perpetual contract trading.

Flexible fee structure to accommodate different trading styles

Shield Mode employs a flexible fee structure, allowing traders to choose the payment method that best suits their strategies and preferences.

In future updates, traders will be able to choose between the following two modes:

• Commission Mode: A fixed percentage fee is charged for each transaction, suitable for stable and high-frequency trading strategies.
• Profit-sharing mode (PnL mode): Fees are charged only when a trade is profitable; it is a performance-based fee structure.

To celebrate the launch of Shield Mode, all Shield Mode transaction fees will be waived until the end of this year.

This upcoming flexible design aims to give traders greater control over costs and allow different trading styles to operate within a fee structure that better aligns with their risk profile and trading behavior.

Laying the foundation for Aster's next stage of development

Shield Mode is more than just a single feature; it embodies Aster's long-term vision. By introducing a protected trading mode to on-chain markets, Aster provides traders with greater privacy and stronger protection for their trading strategies.

At the same time, the complete 1001x experience will be directly integrated into Aster Perpetual, laying the foundation for unifying Aster's core trading products in the future and simplifying how traders access high leverage and manage positions.

Combining gas-free trading and a zero-fee mechanism, Shield Mode sets a new standard for efficiency and performance in on-chain perpetual contract trading. With this launch, Aster positions itself not only as a decentralized exchange but also as a platform specifically designed for professional and high-performance on-chain trading, leading the next stage of on-chain finance development.
