According to TechFlow, Metis has launched the second phase of the decentralized sorter upgrade, introducing features such as multiple transactions, transaction pools, and sorter mining to increase network throughput. Through protocols such as Artemis and Enki, users can stake METIS tokens on Artemis Finance and receive liquid staked tokens artMETIS. Users can also stake METIS through Enki and receive seMETIS, but the protocol uses ENKI for governance. Enki will be deployed on the mainnet soon, but users can already interact with Enki's pre-staking program.
