Is Mantle Restaking Safe?
Risk Grade: B- (33/100)
Mantle Restaking is rated as moderate risk — some novel mechanisms, generally well-understood.
Moderate risk — strong institutional backing and multiple audits, balanced against multi-layer restaking complexity and AVS slashing contagion potential.
Mantle Restaking (mETH Protocol) is a liquid staking and restaking platform that issues mETH for ETH staking and cmETH for restaking across EigenLayer, Karak, and Symbiotic. With $154M TVL in restaking and backed by the broader Mantle ecosystem ($4.2B FDV), its B- grade reflects well-audited infrastructure and strong institutional backing, offset by the inherent risks of multi-layer restaking and AVS slashing contagion.

Key Risks for Mantle Restaking Users
cmETH restakes your ETH across multiple restaking platforms. If any secured service misbehaves, your stake could be partially slashed, reducing the value of your cmETH tokens.
Your investment flows through three layers: ETH → mETH → cmETH. A problem at any layer cascades through the stack.
During high withdrawal demand, the liquidity buffer may not be sufficient, requiring you to wait for ETH unstaking delays.
Top Risk Factors
- •Restaking slashing contagion — cmETH restakes mETH across EigenLayer, Karak, and Symbiotic AVSs. Slashing events on any AVS could reduce the underlying value of cmETH, propagating losses to all cmETH holders regardless of which AVS caused the slashing.
- •Layered token dependency — cmETH's value depends on mETH's value, which depends on ETH staking. This three-layer dependency chain (ETH → mETH → cmETH) means a disruption at any layer cascades through the entire stack.
- •Smart contract complexity — the vertically integrated architecture spanning staking, restaking, liquidity buffers (Aave), and multiple restaking platforms creates a large smart contract surface area.
- •Liquidity risk during mass redemption — while the Aave liquidity buffer helps, a simultaneous exit from cmETH positions could exceed buffer capacity, forcing users to wait for ETH unstaking delays.
