About mETH Protocol
mETH Protocol is a non-custodial ETH liquid staking protocol launched by Mantle. Users stake ETH to receive mETH, a receipt token that accrues staking yield while remaining usable across DeFi. It also launched cmETH, a restaking wrapper, but new cmETH minting was disabled on May 7, 2026; existing holders can still unstake and claim rewards until November 7, 2026.
Its core strength is a hybrid liquidity design: roughly 20% of TVL sits in a buffer pool for near-instant redemptions, while the rest is deployed into Aave's ETH market to earn lending yield. This addresses the industry-wide pain point of long withdrawal queues (often 40+ days during congestion) by targeting ~24-hour redemptions through a FIFO model, and supports large institutional withdrawals directly from Aave reserves.
In the past six months (March–September 2026), the protocol focused on optimizing this buffer pool mechanism, gradually increasing Aave allocation to balance liquidity and yield. It also maintained its position as a top-tier liquid staking protocol with over 480,000 staked ETH (~$1.19B TVL). No major security incidents were reported. The cmETH minting halt is the most notable change, reflecting a strategic pivot toward simplifying its product line.
In the past six months, mETH Protocol centered on the cmETH wind-down.
Negative: cmETH minting stopped from May 7; final EigenLayer rewards distributed mid-June; reward claim deadline Nov 7; fixed cmETH supply may cause premium/discount; peak TVL $620M, exit raised concerns.
Positive: core mETH liquid staking unaffected, redemption and bridging remain; May Mantle reported ~394% MoM increase in mETH treasury holdings, with 200k+ mETH in user wallets, showing accelerating adoption.
