Aster, a privacy-focused trading ecosystem backed by YZi Labs, has launched its Layer 1 blockchain mainnet. The new Aster Chain aims to solve the “transparency trap” in DeFi by making privacy the default state. It uses zero-knowledge encryption and stealth addresses to shield trading activity from public view, aiming to prevent strategies like position hunting. The network claims a throughput of over 100,000 transactions per second with no gas fees.
Aster Chain Mainnet is now officially live. The purpose-built Layer 1 blockchain is designed to tackle what it calls the “transparency trap” of modern decentralized finance. It offers institutional-grade privacy alongside performance claims rivaling centralized exchanges.
The platform argues that complete on-chain transparency creates a critical vulnerability for traders. It cites an incident from March 2025 where a $375 million leveraged Bitcoin short position on a transparent platform was targeted. Traders openly coordinated on social media to pool funds and hunt the position for liquidation.
Aster embeds encryption directly into its execution layer, making privacy the default setting. Its architecture utilizes ZK-verifiable encryption combined with a stealth address mechanism. This ensures no link exists between a user’s wallet and their trading activity on the chain.
Selective disclosure features allow users to make activity public if they choose. With Account Privacy enabled, a user can generate a Viewer Pass to share with selected parties. The network also claims a peak throughput exceeding 100,000 transactions per second with sub-second finality.
“Transparency between a protocol and its users is a fundamental feature, but transparency between a trader and their competitors is a critical vulnerability,” said Leonard, CEO at Aster. He stated that Aster Chain treats privacy as a fundamental requirement for a fair market.
The mainnet launch begins a phased expansion for the ecosystem. Beyond its flagship trading interface, the team is inviting builders to create new DeFi products. A Staking Program will be initiated within a week to reward early supporters and liquidity providers.
