Core Technology and Blockchain Architecture
Mantle Staked Ether (METH) is a pivotal component within the Mantle ecosystem, representing a sophisticated approach to Ethereum staking. It is intricately tied to Mantle LSP, a permissionless and non-custodial liquid staking protocol on Ethereum's Layer 1, designed to optimize capital efficiency and adoption.
METH is a value-accumulating and permissionless ERC-20 receipt token that can easily be adopted by applications. It is earned by staking ETH on the Mantle Liquid Staking Protocol (LSP) and can be unstaked to receive the underlying principal staked ETH and accumulated rewards.
Mantle Staked Ether operates on the Ethereum blockchain, specifically utilizing the advancements brought about by the Ethereum Shanghai Upgrade. This upgrade is pivotal as it enhances the efficiency and security of the Ethereum network, which is crucial for any staking protocol. The Ethereum blockchain employs a proof-of-stake (PoS) consensus mechanism.
Primary Use Cases and Real-World Applications
Mantle LSP facilitates the pooling of ETH deposits from stakers, enabling their participation in rewards generated by Ethereum's proof-of-stake (PoS) validation network. Stakers receive receipt token METH, which represents a claim to the underlying staked principal and accumulated rewards. The receipt token can be utilized in other applications. When stakers unstake their ETH from Mantle LSP, they receive not only the sum of their staked ETH, but also any rewards gained from their staked funds during the staking period.
METH allows investors to participate in the Ethereum network while having the ability to use their METH in other DeFi protocols. METH holders can enjoy the benefits of staking while continuing to use their tokens in various DeFi protocols, diversifying their portfolios.
Both mETH and cmETH can be leveraged across a range of DeFi and centralized applications (with deeper partnership with Bybit), such as collateral for money markets or perpetual trading.
Founding Team and Project History
The idea for mETH came from Mantle "alchemist" Jordi Alexander, chief information officer at Selini Capital.
Originating from a proposal in the Mantle governance forum in July 2023, the protocol allows users to stake ether and receive Mantle-staked ether (mETH) as a token representing their stake.
Mantle DAO, following the approval of governance proposal MIP-25 in August, elected to stake ether from its treasury using its own protocol. This move supplements the DAO's existing $80 million in ETH staked with Lido Finance. Having merged with BitDAO in May 2023, Mantle holds one of the most significant community treasuries in the cryptocurrency space, including assets of $470 million in ether and over $200 million in stablecoins.
Tokenomics
Supply and Distribution
The current circulating supply of Mantle Staked Ether is 231 thousand. The circulating supply of METH tokens is 250 Thousand tokens tradable on the market. The fully diluted valuation (FDV) assumes total number of 250 Thousand ETH tokens are in circulation.
Token Mechanics
When users stake their ETH through the Mantle platform, they receive METH tokens in return at a 1:1 ratio. These METH tokens represent their staked ETH plus accrued staking rewards, with the value of METH gradually increasing relative to ETH as staking rewards accumulate.
Reward Distribution
Rewards from staking include issuance, priority fees, and maximal extractible value (MEV), which are distributed among the stakers, the LSP, and the node operators. This distribution model ensures that all participants in the network are incentivized to maintain its security and efficiency.
Consensus Mechanism and Network Security
The protocol is permissionless and non-custodial, ensuring that users maintain control over their assets while participating in Ethereum's proof-of-stake (PoS) validation network.
The protocol has complete visibility across protocol operations and networks, reinforced by over $5.2M invested in audits and security programs. The protocol partners with top-tier infrastructure providers, while its Guardian network works alongside them to ensure operational safety, achieving zero slashing incidents to date.
Key Partnerships and Ecosystem Integrations
The mETH Protocol is a liquid ETH staking and restaking protocol that maximizes yields — widely accepted as collateral in CEXs & DeFi apps, and money markets.
cmETH is a 1:1 receipt token for mETH restaking across a portfolio of positions, including EigenLayer and associated Actively Validated Services. Rewards accrue in multiple third-party assets, which users can claim periodically.
The most popular exchange to buy and trade Mantle Staked Ether is Bybit, where the most active trading pair METH/ETH has a trading volume of $8,512.21 in the last 24 hours. Other popular options include Merchant Moe Liquidity Book (Mantle) and Agni Finance.
Competitive Advantages and Unique Value Proposition
Mantle created "a lighter weight, more modern Lido," championing the idea of offering a native staking yield on an Ethereum layer-2. The premise is "we should do all of DeFi, but first start by having the 5% yield."
Unlike Blast, Mantle LSP doesn't force anyone to stake or bridge. METH works on Ethereum mainnet and is an independent product from the Mantle Network.
Mantle Staked Ether differentiates itself from competitors by being a non-custodial and permissionless ether liquid staking solution. Its competitive advantages include allowing users to deposit ETH and participate in network staking through validator nodes, receiving mETH as a receipt token that can be restaked across various positions.
Users gain access to enhanced ETH yield with improved liquidity, targeting ~24H redemptions via the Buffer Pool upgrade.
Current Development Activity and Roadmap
Since 2025-10-24, the protocol has implemented the Liquidity Buffer feature which maintains non-staked ETH to meet redemption requests and deposits this ETH into blue-chip lending protocols such as AAVE main markets to maintain yield. Without this feature, withdrawal requests could take as much as 50 days.
COOK is the governance token for mETH Protocol.
The Mantle team has a number of ideas in the works to expand upon the LSP's use within its network, which will be proposed to holders of the MNT governance token.
