mETH (Mantle Staked Ether)

A value-accumulating (reward-bearing) ETH liquid staking receipt token issued by mETH Protocol on Ethereum L1. Balance stays fixed while its ETH exchange rate rises with consensus- and execution-layer staking rewards. Permissionless and non-custodial.

cmETH (Mantle Restaked Ether)

A composable liquid restaking token minted 1:1 when users deposit mETH via the Teller contract. Represents a portfolio of underlying restaking positions across EigenLayer, Symbiotic and Karak plus their AVSs, earning restaking rewards on top of base staking yield.

COOK

Governance token of mETH Protocol (genesis supply 5 billion). Holders vote on protocol direction including staking parameters, reward structures and strategic initiatives. TGE around late October 2024.

BoringVault / PositionManagers

cmETH principal mETH is custodied in BoringVault and can move only to approved addresses/positions. PositionManagers are simple, non-upgradable contracts controlled by BoringVault that constrain permitted calls and integrate third-party restaking protocols; StrategistNodes rebalance the portfolio verified against a MerkleRoot.

Differentiator

Backed by the Mantle treasury and tightly integrated with the Mantle L2 ecosystem and its DeFi venues.

Mantle (Mantle DAO / Treasury)
mETH Protocol is governed by Mantle. Its launch was funded by staking Mantle Treasury ETH, sanctioned via Mantle Governance Proposal MIP-25. COOK is the protocol's dedicated governance token.

Similarity to traditional finance products

How Mantle maps onto established TradFi structures, and where it diverges.

TradFi product	Similarity to Mantle	Key differences
Repo / cash-management sweep on a Treasury position	Like sweeping idle cash into an interest-bearing, redeemable instrument, staking ETH into mETH turns idle ETH into a yield-accruing, transferable claim whose value grows over time.	mETH yield comes from Ethereum PoS validation (variable, subject to slashing) rather than a contractual money-market rate; redemption is subject to on-chain unstake queues and smart-contract risk rather than a regulated custodian.
