The Superposition project, a DeFi-native Layer 3 (L3) protocol based on Arbitrum One, has recently launched the first phase of its testnet. This testnet utilizes the Arbitrum Orbit technology stack and Stylus, focusing on providing a low-cost and fast DeFi experience. The first decentralized application (DApp) on this testnet is Longtail, a V3 automated market maker (AMM) within the Arbitrum ecosystem, which follows a centralized liquidity model similar to Uniswap's.
