mETH Protocol

mETH Protocol is a permissionless, non-custodial ETH liquid staking protocol governed by the Mantle ecosystem. It issues mETH, a yield-bearing LST whose exchange rate against ETH increases with staking rewards, plus cmETH, a restaked variant that captures additional yield through EigenLayer integrations.

The protocol is one of the higher-profile LSTs from an L2 ecosystem, with Mantle backing distribution and product positioning. COOK is the governance token.
