On December 15, 2025, the high-performance, privacy-focused on-chain trading platform Aster, supported by YZi Labs, officially announced the launch of Shield Mode. This brand new protected trading mode has been directly integrated into Aster Perpetual, fully unleashing a high leverage trading experience of up to 1001x in a faster, safer, and more flexible on-chain environment.

Shield Mode is an important milestone in Aster's development of the next-generation on-chain trading platform, aimed at serving professional and advanced traders while addressing the challenges posed by a fully transparent on-chain market.

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

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

Aster's 1001x product is known for continuously pushing the boundaries of on-chain perpetual trading, offering up to 1001x leverage, zero slippage, zero opening fees, and complete on-chain settlement. As the on-chain trading infrastructure matures, traders are increasingly aware of the costs of "complete transparency"—especially the risks of exposing trading strategies and intentions to the market.

In mid-2025, Aster launched Hidden Orders on Aster Perpetual, allowing traders to participate in trades without disclosing price and quantity while maintaining access to deep liquidity. This step introduced greater privacy and strategy protection to on-chain trading.

Building on this foundation, Shield Mode further upgrades to a more comprehensive protected trading mode, combining high leverage performance with stronger protection of trading intentions and a smoother, more controllable trading experience.

Shield Mode: A New Trading Mode from Aster

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

This mode significantly simplifies the process of opening and managing long and short positions by eliminating the need to interact with a public order book; at the same time, traders can seamlessly engage in high-leverage trading without cross-chain switching, avoiding fragmented operations, and no longer needing to frequently perform on-chain signatures.

The core advantages of the Aster 1001x trading model remain intact, including up to 1001x leverage for BTC and ETH, zero slippage, and zero opening fees. On top of this, Shield Mode further enhances efficiency: it eliminates closing fees, completely waives Gas costs, and achieves faster trade execution. Multiple improvements collectively establish a new benchmark for cost efficiency and performance in on-chain perpetual trading.

Flexible Fees to Match Different Trading Styles

Shield Mode features a flexible fee design, allowing traders to choose their payment method based on their strategies and preferences.

In future updates, traders will be able to switch between two modes:

Commission Mode: Charges a transparent, fixed percentage of trading fees per transaction, suitable for high-frequency and stable trading;

PnL Mode: Charges fees only when profits are made, aligning more closely with performance-oriented trading strategies.

To celebrate the launch of Shield Mode, all fees for Shield Mode will be waived for the remainder of the year.
This upcoming flexible mechanism aims to help traders better control trading costs, allowing different trading styles to operate under a fee structure that better matches their risk profiles and behavioral characteristics.

Laying the Foundation for Aster's Next Phase

Shield Mode is not just a single feature upgrade, but part of Aster's grander vision. By introducing a protected trading mode to the on-chain market, Aster provides traders with greater privacy and stronger strategy protection.
