Mantle Staked Ether (METH) is a value-accumulating, permissionless ERC-20 receipt token within the Mantle ecosystem, a project built on Ethereum's layer-2 technology. METH is designed for users who stake Ethereum (ETH) to receive in return, enabling participation in Ethereum's network staking while maintaining liquidity of their staked assets. The Mantle Liquidity Staking Protocol (LSP), as the core product, facilitates this process, allowing users to stake ETH and receive METH, which bears yield. This mechanism is aimed at enhancing capital efficiency and is easily adopted by DeFi applications within the Mantle Layer 2 ecosystem​​​​.

Mantle Staked Ether is used within the Mantle ecosystem to represent staked ETH. Users stake their ETH to receive METH, which then can be utilized within the Mantle Network applications to earn additional yields. This process allows users to participate in network security via staking while also engaging in DeFi activities, without locking their assets in a non-liquid state. This system aims to provide a highly rewarding experience for METH holders, promoting wider adoption and integration across DeFi applications and centralized exchanges​​​​.

Mantle Staked Ether (METH) is a product of the Mantle ecosystem, which operates as part of the broader Ethereum layer-2 landscape. The exact individuals or teams behind the inception of the Mantle project are not explicitly mentioned, but it is governed and developed by a decentralized community of $MNT token holders. These stakeholders are responsible for the strategic direction, including launching new initiatives and managing the ecosystem's significant treasury through proposals and voting mechanisms​​​​.
