mETH Protocol is a permissionless Ethereum liquid staking and restaking platform built by the Mantle ecosystem. Stake ETH to receive mETH (value-accruing receipt token) or restake into cmETH for additional yield across EigenLayer, Symbiotic, and Karak.
Stake ETH → get mETH (earns base staking yield). Optionally restake mETH → cmETH for stacked AVS rewards across EigenLayer, Symbiotic & Karak. Adjust the controls to see how each layer builds on the last.
Holding mETH only — base staking yield, 10% fee on rewards, ~24h typical redemption.
cmETH adds smart-contract and slashing risk from AVS operator sets. Redemptions can take 40+ days via the validator exit queue in peak demand. COOK governance token currently carries no revenue share.

Ethereum staking requires a 32 ETH minimum, validator operations expertise, and locked capital. Existing LSTs are dominated by Lido; users seeking diversification or higher restaking yields lack institutional-grade alternatives integrated with the Mantle / Bybit ecosystem.
mETH Protocol pools ETH deposits, delegates to professional validators, and issues mETH — a value-accruing receipt token. Restake into cmETH for additional EigenLayer / Symbiotic / Karak AVS rewards. The Liquidity Buffer + Aave routing typically settles redemptions within ~24h.
Tight integration with Mantle Network and Bybit, multi-Tier-1 audit coverage (Hexens, MixBytes, Quantstamp, BlockSec), 24h-target redemptions via the LiquidityBuffer + Aave Position Manager, and bundled liquid restaking through cmETH built on Veda's BoringVault.

DeFi Sentinel rates mETH Protocol A with a safety score of 79/100, indicating low-to-moderate risk. The score reflects five risk dimensions: smart contract & technical risk, economic design & market risk, governance & centralization, sustainability & competitive position, and reputation & social trust. mETH Protocol has 14 audits on record. As with all DeFi protocols, residual risk remains and users should review the full risk breakdown before depositing.
