Metis' Layer 2 network, which bundles Ethereum transactions and processes them off-chain then returns them to Ethereum for recording, aims to improve Ethereum's scalability.  Metis provides an NFT bridge between its Andromeda network and Ethereum, NFT storage, a framework for its DAO, decentralized autonomous companies (DACs), and middleware to help developers manage their smart contracts.  The Metis token (METIS) is used in the Metis ecosystem for staking and transaction fees.
