Restaking Explained: Stake Once, Secure Many

Restaking is the latest evolution of Ethereum staking economics. The idea: your staked ETH already secures Ethereum. Why not let it secure other things too, and earn extra yield? EigenLayer pioneered it. Now dozens of protocols follow the same pattern. Understand what you are actually risking before you delegate.

The concept

You stake 32 ETH as an Ethereum validator (or delegate to a liquid staking protocol). Your stake secures Ethereum: if you cheat, part of it gets slashed.

EigenLayer says: 'Point your validator withdrawal address to us. We will make your stake secure additional services on top of Ethereum. In exchange, you earn extra fees. But if the service catches you misbehaving, you can also be slashed for that service's rules.'

What gets secured

The services secured by restaked ETH are called Actively Validated Services (AVSs). Categories:

Data availability layers — EigenDA, alternative DA options for L2s
Oracle networks — Alternative to Chainlink
Bridge validator sets — Cross-chain messaging protocols
Prover networks — ZK proof generation services
MEV networks — Enforcement of specific block-building policies

Each AVS pays fees to restakers who commit to running its software. Each also has its own slashing conditions.

The risk stack

Standard staking = one way to lose your stake (Ethereum slashing). Restaking = many ways to lose your stake.

1. Base Ethereum slashing

If your validator double-signs or goes offline, standard slashing applies. Up to 32 ETH gone.

2. AVS slashing (per service)Each AVS defines its own slashing conditions. Missed a proof submission window? Slashed. Signed an invalid oracle report? Slashed. If you secure 5 AVSs, you have 5 extra ways to lose stake.

3. Correlated failures

If a bug in EigenLayer's core contracts slashes many stakers at once, the market absorbs a big supply shock in ETH selling. This is the systemic risk that concerns Vitalik and the broader Ethereum research community.

4. Liquid restaking tokens (LRTs)

Just like LSTs (stETH), LRTs (ezETH, weETH, rsETH) wrap restaked positions in a tradeable token. Now you have LST risk + restaking risk + LRT wrapper risk stacked. During panic, LRTs can depeg from ETH the way stETH did in 2022, but with steeper drawdowns because more risk layers must unwind simultaneously.

The economics that make it work

An AVS pays fees to attract restakers to secure it. If your staked ETH earns 3% base yield plus 2% from restaking, you outperform pure staking without buying more ETH. Meanwhile, the AVS gets high-value security cheaper than issuing its own token and running its own validator set.

This is genuinely useful. It lets new networks bootstrap security by renting Ethereum's economic weight instead of paying to build their own. But it does concentrate risk in a way Ethereum has not experienced before.

How to think about opting in

Restaking decision framework

Question	Answer
Which AVSs am I securing?	Named list, not 'auto-restake all'
What is each AVS slashing rule?	Read the docs. If you cannot understand it, do not opt in.
Is the fee premium worth the extra risk?	Extra 1-3% yield vs multiple new slashing conditions
Are you using an LRT wrapper?	Adds LRT depeg risk on top of everything else

What to remember

Restaking is powerful DeFi primitive that also stacks new risks. Extra yield comes from taking on extra slashing exposure across multiple services. Understand each service. Prefer to hold a small allocation and diversify across LRTs rather than concentrating everything in one wrapper. And expect at least one high-profile slashing event in the next year that will test how the market prices this risk.
