Put Your ETH to Work: A Starter Guide to mETH Protocol

Whether you're deep into DeFi or just getting started, mETH Protocol makes it simple to earn yield on your ETH — no validator setup, no platform-hopping.

This guide walks you through the basics and helps you take the first steps toward unlocking the full yield potential of your idle ETH.

What is mETH Protocol?

Incubated by Mantle, mETH Protocol began as a modest product in December 2023, offering users diverse ways to enjoy enhanced yield opportunities on their ETH.

Today, mETH Protocol is the 4th largest liquid staking protocol and the 6th largest liquid staking protocol, trusted by both retail and institutional users to deliver scalable and transparent yield opportunities.

Core Assets: A Refresher

$mETH: A vanilla liquid staking token representing staked $ETH, integrated across a wide range of native protocols on Ethereum and Mantle Network, including liquidity pools, money markets, perpetuals, and more.
$cmETH: A liquid restaking token (restaked version of $mETH) that enables users to earn rewards across multiple restaking protocols such as EigenLayer, Karak, Symbiotic, and Veda, while also deploying assets across integrations for enhanced yields.
$COOK: The governance token of mETH Protocol, used to vote on ecosystem direction and other strategic matters.
