How to mint cmETH on Bybit

Liquid staking has become an essential tool for ETH holders looking to earn passive income without sacrificing liquidity. But now, with restaking solutions like cmETH, users can go beyond traditional rewards by earning layered yields through protocols such as EigenLayer.

In this guide, we’ll walk through everything you need to know about cmETH, how it compares with mETH, what rewards to expect and how to mint it easily on Bybit’s On-Chain Earn platform — especially during the 30-day, limited-time bonus event running from Jun 10, 2025 through Jul 10, 2025 in partnership with Mantle Network and EigenLayer.

Key Takeaways:

• cmETH is a liquid restaking token that represents staked ETH within Mantle Network’s ecosystem.

• You can mint cmETH on Bybit by using either ETH or mETH.

• Bybit is collaborating with EigenLayer and Mantle for a limited-time event, bringing additional rewards like higher APRs and airdrops when you mint cmETH during the event period.





What is EigenLayer?

EigenLayer is a restaking protocol built on Ethereum that allows users to reuse their staked ETH (or liquid staking tokens, such as mETH, to secure additional networks and decentralized services called Actively Validated Services (AVS).

At its core, EigenLayer allows users to “restake” ETH or liquid staking tokens (LSTs) like mETH that are already staked for Ethereum's proof of stake (PoS) consensus. Instead of just earning base staking rewards, users can opt in to restake those same assets to support other decentralized services, including oracles, bridges, data availability layers and more.

This creates a powerful shared security model, whereby multiple protocols can leverage Ethereum’s validator set without having to bootstrap their own trust networks from scratch. For users, it means earning additional incentives (often in the form of native tokens like EIGEN) — on top of their regular staking rewards — simply by opting in to restake.

EigenLayer is quickly becoming a foundational layer for Ethereum’s modular future, attracting widespread attention from both developers and stakers. As more AVS launch on EigenLayer, the opportunities for restakers continue to grow.

How does EigenLayer work?

Following is a simple breakdown of how EigenLayer works.

Opt-in restaking

Users who have staked ETH (either directly or via LSTs) can opt in to restake their assets on EigenLayer. This means they're extending the security of their stake to other networks, not just Ethereum.

Actively Validated Services (AVS)

AVS are services that tap into EigenLayer’s pooled security. These can include oracle networks, cross-chain bridges, data availability layers, rollup sequencers and more. Restakers delegate their stakes to operators running these services, thereby helping to secure operations.

Slashing conditions

Because restakers are now providing security to multiple protocols, misbehavior (e.g., downtime or dishonest validation) on any AVS can trigger slashing of restaked assets. This ensures accountability and maintains security across all layers.

When you mint cmETH on Bybit, your ETH or mETH is automatically routed through Mantle Network and restaked on EigenLayer. This gives you exposure to EigenLayer’s AVS ecosystem and allows you to earn dual rewards (Ethereum staking yield and bonus AVS incentives) in a single step, without needing to restake manually.

What is cmETH?

cmETH is a liquid restaking token that represents staked ETH within the Mantle Network ecosystem, enabling holders to earn rewards from Ethereum staking and additional restaking protocols, such as EigenLayer. It’s designed to provide users with a seamless staking experience, and combines the benefits of Ethereum's proof of stake (PoS) rewards with additional yields from restaking strategies.

cmETH vs. mETH

While both cmETH and mETH are integral to the Mantle Network staking ecosystem, they serve distinct purposes:

• mETH: Represents ETH staked directly in Mantle's liquid staking protocol. Holders earn rewards solely from Ethereum's PoS mechanism.

• cmETH: Represents mETH that has been restaked across various protocols, including EigenLayer and other Actively Validated Services (AVS). This restaking allows cmETH holders to earn additional rewards beyond the base Ethereum staking yields.

In essence, cmETH offers a multi-layered yield approach, combining base staking rewards with additional incentives from restaking activities.

Benefits of minting cmETH

Staking cmETH presents several advantages for users seeking to maximize their ETH holdings:

• Dual rewards: Receive a 1% bonus in cmETH, plus additional rewards in EigenLayer and partner tokens (e.g., OWN).

• Full liquidity: cmETH remains tradable and usable across DeFi, even while earning.

• Simple UI and tracking: View rewards, lock-in period and pending balances directly on Bybit’s interface.

• No technical setup required: No need to manually restake or manage EigenLayer, as Bybit handles the back-end processes for you.

Current cmETH yield structure

During the limited-time bonus event running from Jun 10, 2025 through Jul 10, 2025, minting cmETH on Bybit will entitle users to:

• A cmETH staking APR of 3.43%, which applies to all eligible cmETH minted via ETH or mETH.

• Additional 2% APR in EIGEN or partner tokens: Distributed to users proportionally, based on their holdings.

• A maximum bonus APR cap of 15%.

• Lock-in duration of 41 days; bonus rewards are distributed after this period.

Please note that only new deposits and staking actions made during the event window are eligible for bonus rewards. A 24-hour minimum holding snapshot is used to calculate eligibility. In addition, bonus rewards are only available for cmETH minted during the event window, and they require a 41-day holding period in order to qualify for full distribution.

How to earn additional interest rate bonus

When you mint cmETH during the event period (Jun 10, 2025 through Jul 10, 2025), the bonus interest is automatically applied. The total APR for cmETH is 3.43%, which includes both the base Ethereum staking yield and additional bonus yield from EigenLayer in the form of EIGEN or partner tokens. There’s no need to claim anything manually. Once your ETH or mETH is staked, your rewards start accumulating immediately.

Please note that the interest will stop accumulating once you initiate redemption, and your rewards will be finalized based on your average holdings over the 41-day lock-in period. These rewards will be unlocked and distributed automatically on the 41st day of the event.

Additional referral perks

While the event primarily focuses on staking bonuses, Bybit is also offering an additional referral perk when you send this article to a friend and invite them to participate in this limited-time event with your referral link. Upon successful referral, you’ll receive an additional airdrop of EIGEN or USDT, which will be unlocked on the 41st day of the event.
