About Aster DEX
Aster DEX is a non-custodial perpetuals exchange that lets traders pick their chain — BNB Chain, Ethereum, Solana, or Arbitrum — and trade against pooled cross-chain liquidity without bridging. Users can place hidden limit orders, go up to 1001x leverage, and trade tokenized U.S. stock perps that settle in crypto. Formed from the 2024 merger of Astherus and APX Finance and backed by YZi Labs, Aster has cleared over $1T in cumulative volume from more than 4M users.
