cmETH is a 1:1 receipt token for mETH restaking across a portfolio of positions, including EigenLayer, Symbiotic, Karak and associated Actively Validated Services. Rewards will accrue in multiple third-party assets, which users can claim periodically.

If you have ETH or mETH on Ethereum L1, you can get cmETH by restaking your mETH and then bridging it to Mantle L2.

If you hold assets on Mantle L2, you can get cmETH by swapping on one of the decentralized exchanges listed on meth.mantle.xyz/swap.

There is no lockup period for cmETH. However, there is an 8-hour waiting period when unstaking cmETH, and it is subject to the mETH availability in the unstake queue.
