Mantle Staked Ether

Mantle Staked Ether (mETH) is plain ETH liquid staking, structurally simpler than the restaking products that surround it, and it has the fastest verified exit of any liquid staking token we rate. Its unstake queue currently shows zero deficit with every outstanding request already fully funded, giving a roughly twelve-hour finalisation against a liquid buffer of about 21,000 ETH, close to nine percent of TVL. mETH scores 54/100 (Tier 3) on the RWTS Trust Score. What holds it back is not operations but accountability: Mantle's terms name no legal entity at all, so there is no identifiable issuer, no licence holder and no counterparty responsible for the peg. The validator set is not publicly enumerable, only aggregate balances are published, and the sponsoring treasury that would backstop any stress is 70 percent Mantle's own MNT token, which means the backstop is correlated with the risk it would be called on to cover. TVL is down 73 percent from its March 2024 peak. The related restaking wrapper cmETH is deliberately excluded from our corpus: minting was halted on 7 May 2026 and it has lost 95 percent of peak value, so rating it as a live product would mislead.

Scored on the published RWTS methodology (v1.1), reviewed quarterly and on material events. Ratings are independent and never pay-influenced.

Calculations are indicative. Actual yields may vary.

Projections assume constant APY of 1.90%. Actual returns may vary. Not financial advice.

Beyond mETH's own score, two structural questions matter: what is it built on, and what has broken before in this part of the market. A high score in isolation can still carry hidden, shared exposure.

Liquidity read: TVL of $583.08M indicates healthy on-chain liquidity. Lock-up: Roughly 12 hours at current funding levels, longer if the liquid buffer is exhausted.
