Is mETH Protocol Safe?
Risk Grade: B- (32/100)
mETH Protocol is rated as moderate risk — some novel mechanisms, generally well-understood.
Moderate risk — proven LST model with strong institutional backing, balanced against Mantle ecosystem concentration and novel cross-chain restaking risk.
mETH Protocol is Mantle's institutional-grade ETH liquid staking platform, allowing users to stake ETH and receive mETH, a reward-bearing LST. With $579M TVL, the protocol also offers cmETH for cross-chain restaking across Mantle, Ethereum, and HyperEVM. Its B grade reflects a proven LST model with strong documentation and audits, tempered by ecosystem concentration risk and the novel cross-chain restaking extension.

Key Risks for mETH Protocol Users
mETH is deeply integrated into the Mantle ecosystem, which means problems at Mantle could directly affect your staked ETH. The protocol is not fully independent from Mantle governance.
cmETH restaking exposes your ETH to additional slashing risk from AVS operator misbehavior. If an operator secured by cmETH is slashed, the value of your token decreases.
Instant redemptions through the Buffer Pool rely on Aave liquidity. During periods of high demand, you may need to wait in a queue to unstake your ETH.
Top Risk Factors
- •mETH is operated by Mantle, creating concentration risk around the Mantle ecosystem. If Mantle faces governance issues, regulatory action, or operational failures, mETH holders are directly exposed.
- •The Buffer Pool mechanism routes a portion of validator ETH through Aave to enable instant redemptions. This introduces smart contract dependency on Aave and potential liquidity issues if Aave utilization is high when redemptions spike.
- •cmETH (cross-chain mETH restaking) extends exposure to multiple chains via restaking, introducing slashing contagion risk. Poor performance or misbehavior by one AVS operator could trigger slashing affecting all cmETH holders.
- •With $579M TVL and ~88.9% market share of HYPE LSTs (per Kinetiq data), concentration in a single LST provider creates systemic risk for the Mantle ecosystem.
