Slashing Risk

Slashing is a penalty that Ethereum, and separately EigenLayer, can take out of staked ETH when a validator or operator breaks the rules. ether.fi helps secure Ethereum, and through EigenLayer it helps secure other services that run on restaked ETH, so it is worth being clear about where that penalty can come from and how much is at risk.

There are two places slashing can happen:

1. Ethereum validators.

2. EigenLayer services that restaked ETH helps secure.

Ethereum validator slashing

Ethereum penalizes a validator when it provably breaks the rules, mainly by signing two conflicting blocks or votes. The validator pays an upfront penalty, is removed from staking, and pays a further penalty that grows if many validators are slashed in the same short window.

The upfront penalty is small. After the Pectra upgrade in May 2025 it dropped to one part in 4,096 of the validator's balance, which is about 0.008 ETH for a 32 ETH validator. Before Pectra it was about 1 ETH. The added penalty for correlated slashing only becomes significant if a large share of the whole network is slashed at the same time, which has never happened.

ether.fi stakes through a curated set of professional operators that run different software and infrastructure, which keeps the chance of a shared fault low. — No ether.fi validator has been slashed since the protocol launched.

ether.fi has partnered with Nexus Mutual to provide the largest ETH slashing cover in crypto history: up to 15,000 ETH in validator slashing penalties, protecting one of the largest validator sets on Ethereum.

EigenLayer restaking slashing

When ETH is restaked through EigenLayer, the services it helps secure can also slash it. This only applies when every party opts in: the service has to turn on slashing, the operator has to sign up to secure it, and the protocol has to choose that operator. Which operators are signed up to slashable services is recorded on-chain and shown in the EigenLayer app, so anyone can check it.

ether.fi's restaked ETH is not signed up to any slashable service, and as a matter of policy ether.fi does not sign up to slashable services. — There is no restaking slashing risk today.

Separately, ether.fi is removing its exposure to restaking altogether, and that wind-down is nearly complete. Most assets have already been unrestaked: as of August 2026, less than 1% of ether.fi's assets remain restaked with EigenLayer, down from about half in early 2026. The remainder is planned to be removed by Q3 2026, bringing the restaked share to 0%. Going further, ether.fi plans to completely remove EigenPod withdrawal credentials from its validators by Q4 2026, eliminating the protocol's last structural link to EigenLayer. This shrinks the restaking exposure overall, not only the slashable part.

How much is at risk

Where	What triggers it	Most that can be lost	Today	Backstop
Ethereum validator	Signing conflicting blocks or votes	About 0.008 ETH per 32 ETH validator; more only in a network-wide event	Spread across diverse operators; never slashed	Nexus Mutual's ETH Slashing Umbrella Cover, up to 15,000 ETH
EigenLayer restaking	A service's slashing rule is broken	Limited to what is signed up to slashable services	Nothing signed up with slashable AVS; less than 1% of assets still restaked	Policy of not joining slashable services, plus the near-complete wind-down of restaking (0% planned by Q3 2026)

Because none of ether.fi's restaked ETH is signed up to slashable services, the restaking slashing risk is effectively zero today. The overall restaked share is already below 1% and is planned to reach 0% by Q3 2026, with EigenPod withdrawal credentials removed from all validators by Q4 2026.
