Mantle Staked ETH (mETH) is a value-accumulating receipt token issued for ETH deposited into the mETH Protocol. Its value is intended to reflect staked ETH and accumulated rewards rather than a fixed dollar peg. The protocol documentation describes mETH separately from cmETH, a restaking receipt with additional third-party risks.

How mETH Works
Users deposit ETH into the protocol and receive mETH. The protocol stakes ETH with Ethereum validators, and the value relationship between mETH and ETH can reflect rewards as they accrue. mETH is designed as a transferable receipt token, so it may be used in supported applications; each application adds its own smart-contract, liquidity, and counterparty risks. A market quote can move away from a protocol redemption value.
Withdrawals and the Liquidity Buffer
The current protocol documentation describes withdrawals as permissionless requests processed through a first-in, first-out queue, with a minimum 12-hour delay. The maximum wait depends on available liquid ETH and the Ethereum validator exit queue. Documentation also describes a liquidity buffer that keeps some ETH available for redemption and is in capped production testing; it says that without the buffer, requests could take as long as 50 days. These are protocol descriptions, not guarantees that a withdrawal will complete by a particular time.
Tokenomics and Fees
mETH does not have a fixed maximum supply in the CoinGecko snapshot above. Its token supply changes with deposits and redemptions, while accumulated rewards affect the amount of ETH represented by a token. The current documentation lists a 4-basis-point deposit fee and a protocol fee of approximately 10% of rewards; it lists no withdrawal fee. Fees and operational parameters can change, so consult the live protocol documentation before relying on these figures.
mETH and cmETH Are Not the Same
mETH represents the liquid-staked ETH product. The documentation describes cmETH as a receipt token for restaking positions that may involve EigenLayer and third-party services. Restaking can introduce risks beyond Ethereum validator staking. A page or application that displays the similar names should therefore be checked for the exact token and contract before transferring assets.
