Our verdict on Mantle Restaking

7.3/10

Mantle Restaking (mETH Protocol) suits ETH holders who want staking yield while keeping a liquid token, and who care about quick exits. Its main strength is the tiered redemption design, with an instant buffer for small withdrawals and an Aave-backed route for larger ones, plus Proof of Reserves reporting and listed audits. The main caveat is that the APY, redemption times and zero-slashing claims come from the project itself, and the usual smart-contract, validator and depeg risks still apply.

What is Mantle Restaking?

Mantle Restaking is the DefiLlama listing for mETH Protocol, an Ethereum liquid staking and restaking protocol built by Mantle. The homepage describes it as the first fully vertically integrated staking and restaking protocol in the market, aimed at institutional-grade use.

DefiLlama shows about $38.96 million in TVL on Ethereum, up about 3% over seven days, with 2 audits listed. It has been tracked since November 2024. The homepage TVL counter showed $0 in the scraped text, so the DefiLlama figure is the more reliable number here.

The main pitch is liquidity. The site claims about 5.00% net APY and redemptions in around 24 hours, backed by an allocation to Aave's ETH market. These are the project's own claims and should be checked in the live app.

How Mantle Restaking works

You deposit ETH into the protocol and receive mETH. The protocol stakes the ETH with validators run by infrastructure providers, and the mETH token accrues value as staking rewards come in, rather than paying rewards as separate tokens.

To help with exits, the homepage describes two redemption routes. Small redemptions are served from an Instant Buffer pool in roughly 1 to 5 minutes. Larger ones draw on a reserve held in Aave's ETH market and take about 24 hours. The site contrasts this with other liquid staking tokens at roughly 9.30 days, though that is the project's own comparison.

The mETH token can then be used in DeFi, for example in liquidity pools, lending, money markets and vaults, or as collateral on exchanges such as Bybit and Kraken. DefiLlama files the project under liquid restaking on Ethereum.

7 features

Key features

Liquid staking token

Deposit ETH and receive mETH, a value-accruing receipt token backed by staked ETH, while keeping the position liquid.

Tiered redemption flow

Small redemptions use an Instant Buffer pool (about 1-5 minutes). Larger ones go through Aave's ETH Market in about 24 hours.

Aave liquidity reserve

The homepage says about 30% of the protocol is allocated to Aave, versus 0% for other LSTs, to support deeper redemption liquidity.

Proof of Reserves

The site links to a Proof of Reserves page and shows mETH underlying collateral and validator performance.

DeFi and exchange integrations

The homepage lists 40+ integration partners across liquidity pools, lending, money markets, vaults and exchanges.

Guardian network

The site mentions a Guardian network working alongside infrastructure providers, with zero slashing incidents reported to date.

MiCA whitepaper

The site links to a MiCA whitepaper, relevant to European regulatory disclosure for crypto-assets.

Pros and cons

What we like

Clear redemption design: a small-withdrawal buffer plus an Aave-backed route for larger exits.
Proof of Reserves page and visible validator and collateral reporting.
2 audits listed on DefiLlama, and the homepage states over $1M invested in audits and security.
Zero slashing incidents reported to date, per the project.
Wide integration list, including DeFi venues and exchanges such as Bybit and Kraken.

Watch out for

Smart-contract risk applies, even with audits listed; audits reduce but do not remove the chance of bugs.
The advertised 5.00% APY and ~24H redemption time are the project's own figures and can change; conditions apply to redemptions.
Large redemptions depend on Aave's ETH market liquidity, which adds a dependency on another protocol.
Liquid staking tokens like mETH can trade below the value of the underlying ETH during market stress.
Many of the listed yield venues and integrations sit outside Ethereum mainnet, adding extra layers of risk if mETH is used as collateral.
DefiLlama lists no governance token for it, and the project does not say how decisions or upgrades are controlled.

Mantle Restaking fees

The project does not publish a fee breakdown. The homepage quotes a net protocol APY of about 5.00%, which suggests rewards are shown after any protocol take, but the fee rate is not stated.

Users would also pay Ethereum network gas for deposits and redemptions, plus any fees or spreads on third-party venues where mETH is used. Check the app and docs for current figures.

Is Mantle Restaking safe?

DefiLlama lists 2 audits, and the homepage says over $1M has been invested in audits and security programs and that there have been no slashing incidents. The audit firms and reports are not named publicly, so readers should find them in the docs.

Risks remain. These include smart-contract bugs, validator slashing, dependence on Aave for large redemptions, and the chance that mETH trades below the underlying ETH value. Using mETH in other DeFi protocols adds further layers. The project does not describe the custody or governance model in detail, and do not mention any past incidents.

Who Mantle Restaking is for

This is for ETH holders comfortable with DeFi who want staking rewards without locking funds, and who value faster redemptions than a typical liquid staking token.
