mETH Protocol: Institutional-Grade ETH Liquid Staking
mETH Protocol is a fully vertically integrated staking and restaking protocol on Ethereum, built by the Mantle team, designed for anyone holding ETH who wants to earn while keeping their position liquid.
Start StakingExchange rate: 1 mETH = 1.0909 ETH. Protocol status: Active. Reward fee: 10%. Audited smart contracts deployed on Ethereum mainnet.
How It Works
The mETH Protocol protocol turns native ETH into a productive, liquid asset. The process is transparent and runs entirely on-chain. No lockups unless you choose the native unstake path.
Connect Your Wallet
Use MetaMask, WalletConnect, or any compatible wallet. The mETH Protocol platform requires no registration — your address is your account.
Deposit ETH
Enter a minimum of 0.02 ETH. The protocol applies a 0.04% adjustment rate at the point of entry. Larger deposits incur the same rate — no tiering.
Receive mETH
mETH arrives in your wallet within 1–5 minutes. It represents your ETH principal plus accruing staking rewards. The exchange rate rises as rewards accumulate.
Earn or Restake
Hold mETH to earn base staking yield. Or deposit into the restaking module for a second reward layer. Many users also supply mETH liquidity on Uniswap for additional yield.
Exit When Ready
Initiate a native unstake — around 4 days — or swap mETH directly on supported DEXs. No penalty applies to the unstake path; the only cost is gas.
Key Features
Vertical Integration
mETH Protocol is the only protocol that handles both staking and restaking within a single architecture. You don't need separate platforms or separate tokens for each layer of yield.
Liquid mETH Token
mETH is a standard ERC-20 token tradeable on Uniswap, Curve, and a range of other venues. Supply cap stands at 3,000,000 mETH. Current circulating supply: approximately 251,563 mETH.
No Slippage on Stake/Unstake
The native stake and unstake paths apply no slippage. Only the 0.04% adjustment rate affects entry. Compare this with DEX swaps, which carry variable slippage depending on pool depth.
Audited Smart Contracts
Independent auditors have reviewed the mETH Protocol's protocol contracts. Reports are accessible through the Mantle documentation portal. On-chain code is immutable once deployed.
Cross-Chain Presence
While mETH Protocol is rooted on Ethereum mainnet, mETH is bridgeable to Mantle Network and other chains. Polygon users can also access mETH exposure via wrapped or bridged assets on supported DEXs.
Transparent Protocol Status
TVL, APY, mETH supply, and exchange rate are published in real time on the main dashboard. No opaque off-chain calculations. Every metric is derivable from on-chain data.
Delegation Module
The delegation feature lets token holders assign staking decisions to vetted operators. It mirrors concepts found in Ethereum's proof-of-stake consensus design.
mETH Protocol by the Numbers
Hard data matters more than marketing copy. Here is where the mETH Protocol platform stands today.
Data reflects on-chain values as of April 2026. For deeper historical data, see the Ethereum protocol overview on Wikipedia for context on how staking rewards are generated at the consensus layer.
Why mETH Protocol
Honestly, the case for mETH Protocol comes down to a few things that competing protocols don't combine in one place. Let's be direct about what sets it apart.
Single Protocol, Two Yield Layers
Base Ethereum staking plus restaking in one contract set. No additional bridges, no separate reward claims, no fragmented positions across different platforms.
Built by a Known Team
The team behind mETH Protocol is the same group that builds Mantle Network — a public, identifiable organization with a track record since 2022. Anonymous protocols carry unknown operational risk.
Immediate Liquidity Option
mETH trades on Uniswap v3 and other AMMs. If you need funds before the 4-day native window, you exit via a swap. Most protocols offer only native unstaking or require weeks.
Conservative Supply Cap
A hard cap of 3,000,000 mETH prevents unchecked expansion of supply. Current issuance is roughly 8.4% of that ceiling, which leaves substantial room without dilution pressure on the exchange rate.

FAQ
What is mETH Protocol?
mETH Protocol is the first fully vertically integrated ETH liquid staking and restaking protocol, built by the Mantle team. It issues mETH tokens representing staked ETH positions, currently at an exchange rate of 1 mETH = 1.0909 ETH. The protocol launched on Ethereum mainnet and has accumulated over 274,000 ETH in TVL as of early 2026.
How do I stake ETH with mETH Protocol?
Connect a compatible Web3 wallet to the mETH Protocol platform, enter an amount of at least 0.02 ETH, and confirm the transaction. mETH tokens arrive in your wallet within 1–5 minutes. The protocol applies a 0.04% adjustment rate at entry; beyond that, there are no hidden fees on the stake path.
Is mETH Protocol safe and audited?
mETH Protocol has completed multiple independent security audits. Contract code is deployed on Ethereum mainnet and publicly verifiable. Audit reports are published through the Mantle documentation portal. That said, no smart contract protocol carries zero risk — users should read the available documentation before depositing.
What APY does mETH Protocol currently offer?
Current mETH APY sits at approximately 1.71%. This figure comes from Ethereum consensus-layer staking rewards, minus the protocol's 10% reward fee. APY changes gradually as network participation rates shift. Historical APY data is accessible on the main dashboard.
Can I unstake if I need liquidity quickly?
The native unstake path requires roughly 4 days and a minimum of 0.01 ETH. For faster exits, mETH can be sold on Uniswap or other supported swap venues without waiting. The Explore section on the main app lists all active trading venues.
Why should I choose mETH Protocol over other staking options?
mETH Protocol combines base Ethereum staking and restaking within one protocol, rather than requiring separate platforms. The TVL exceeds 274,000 ETH, the mETH supply cap is fixed at 3,000,000 tokens, and the Mantle team operates transparently. For users already active on Polygon or using Uniswap liquidity strategies, mETH slots into existing DeFi workflows without new infrastructure.
What is the minimum stake amount?
The minimum stake is 0.02 ETH. The minimum for native unstaking is 0.01 ETH. Users who want exposure below the 0.02 ETH threshold can buy mETH directly through Uniswap or other DEX venues listed on the Explore page.
How does restaking work on mETH Protocol?
Once you hold mETH, the restaking module lets you deploy those tokens to earn a second layer of yield on top of base staking rewards. Restaking exposes your position to additional operator risk, so the mETH Protocol platform surfaces those parameters clearly before you confirm. Detailed restaking mechanics are documented on the support page.
