About Superposition
Superposition is a DeFi-native Layer-3 blockchain network identified by chain ID 55244. It utilizes Ether (ETH) as its native currency, with 18 decimal places. The network is built on the Arbitrum Orbit technology stack and employs Stylus for enhanced performance. Superposition features a native on-chain order book, aiming to provide faster execution speeds, shared and permissionless liquidity, and reduced fees. It also introduces "Super Assets," which yield rewards for both holding and using them.
Developed by Fluidity Labs, Superposition launched its first phase of testnet in June 2024. The network is designed to support decentralized applications (dApps) by offering a unified liquidity layer that combines automated market maker (AMM) functionality with an order book. This approach aims to facilitate application growth from first principles, providing a scalable and composable environment for developers.
For developers and users, Superposition offers tools such as a block explorer for monitoring transactions and smart contracts, and RPC endpoints for network interaction. The network's official resources provide additional documentation for building and engaging with the Superposition ecosystem.
