Aster Launches Privacy-Focused Layer 1

Aster, the BNB Chain-native perp DEX backed by YZi Labs, has launched the genesis phase of Aster Chain, its privacy-focused Layer 1 blockchain, the team announced on X.

According to the announcement, Aster Chain is launching in a phased sequence: Chain Genesis is already live, with a partnership reveal slated for tomorrow, public staking for ASTER token holders opening later this week, and an ecosystem expansion and “Aster Code partners program” to follow. A brand and UI upgrade is also in the pipeline, per the announcement.

Aster underlined that the new L1’s primary feature is its privacy architecture, with “Account Privacy” turned on by default. Per Aster Chain’s documentation, every order place in the default privacy mode is verifiable and encrypted via Zero-Knowledge (ZK) cryptography. In addition, every transaction is routed through a one-time stealth address, making it impossible to link a wallet to its trading activity.

For traders who want to selectively disclose their activity — to an auditor, counterparty, or regulator — Aster is introducing a “viewer pass” mechanism: a user-generated key that decrypts their on-chain records for anyone they choose to share it with, while keeping everything else locked.

Aster Chain’s documentation also states that the chain is designed to be high-performance, “optimized for ultra-low latency trading environments.” Per the documentation, the L1 has a block time of 50 milliseconds and processes up to 100,000 Transaction Per Second (TPS). It also boast zero gas fees.

“This performance enables Aster to deliver a trading experience comparable to centralized exchanges while preserving decentralized settlement and verification,” the documentation states.

The launch of a privacy-focused L1 for the DEX builds on past moves. Last June, as the so-called perp DEX wars were just heating up, Aster launched a “hidden orders” feature, allowing traders to conceal order size from the public order book. Aster launched the feature less than three weeks after Binance co-founder CZ publicly floated the idea of “dark pool” perpetuals trading.

Perp DEX Mania

Aster Chain’s mainnet launch comes as the protocol cements its place near the top of a market that barely existed at scale two years ago — on-chain perps trading.

Aster is currently the second-largest perp DEX by trading volumes after Hyperliquid, with $3.36 billion in trades in the past 24 hours and $18.6 billion in the past week, per data from DefiLlama.

As The Defiant has tracked, 2025 became the breakout year for on-chain perpetuals, with a wave of challengers — Aster among them — emerging after Hyperliquid’s token launch in late 2024, and rising popularity following. That momentum only accelerated: September marked the first time perp DEX volume exceeded $1 trillion in a single month, nearly 50% higher than August, with Aster, Hyperliquid, and Lighter locked in an increasingly fierce battle for dominance.

When the DEX’s ASTER token launched in September, the token surged 875% on its opening day, quickly reaching a $1.9 billion market cap — driven in large part by CZ’s vocal promotion on X.

The launch of a proprietary chain now positions Aster squarely against Hyperliquid’s core advantage: a purpose-built L1 as the foundation for its market dominance.

Meanwhile, ASTER is up 7% on today’s news, trading around $0.76, or a $1.88 billion market cap.
