EigenLayer Restaking Explained: How It Works, Real Yields, and the Risks

Quick answer: Restaking lets you reuse already-staked ETH to help secure extra networks and earn rewards on top of base Ethereum staking yield. EigenLayer pioneered the model. It sounds like free money stacked on free money, but 2026's biggest DeFi hacks showed where that extra yield's risk actually lives.

Liquid staking solved one problem: stake ETH and still hold a liquid token like stETH or rETH. Restaking asks a bigger question. If that ETH is already securing Ethereum, why can't it also help secure other networks and get paid for it?

That question built a whole new sector. In April 2026, it also sat next to one of the largest DeFi exploits of the year. Both things are true. You need both before you put money in.

How Restaking Actually Works

You start with a liquid staking token: stETH from Lido, rETH from Rocket Pool, or something similar. Deposit that LST into EigenLayer (or a similar restaking platform), and it gets re-delegated to help secure extra services. Oracles, bridges, data availability layers, and other infrastructure that needs economic security without building a full validator set from scratch. These services are often called Actively Validated Services (AVSs).

In return, you can earn extra rewards on top of base Ethereum staking yield, which sits around 3.5% to 4.2%. In theory, one ETH position can stack:

1. Ethereum validation rewards
2. EigenLayer operator rewards
3. Yield from DeFi protocols that accept the restaked position

That "one deposit, multiple income streams" pitch is why restaking grew so fast. It is also why the risk stacks the same way the yield does.

Where the Extra Yield Actually Comes From

This part matters more than most explainers admit.

The extra yield is not free. It is payment for taking on slashing risk across every AVS your restaked ETH helps secure, not just Ethereum. If Ethereum validators misbehave, they get slashed. Restake into an AVS, and you can also get slashed for that service's failures: bugs, downtime, or bad behavior in a system you probably do not fully understand.

The real trade is simple: more income streams in exchange for more ways to lose a slice of your principal.

Liquid Restaking Tokens (LRTs): Why They Are Riskier Than They Look

To keep restaked positions liquid, protocols issue Liquid Restaking Tokens like rsETH and similar variants. On paper, this is the same convenience trick liquid staking used for base ETH.

In practice, it adds a bridge and a peg on top of an already layered risk stack. In April 2026, that is exactly where it broke.

The Kelp DAO Lesson

On April 19, 2026, Kelp DAO, a liquid restaking protocol, lost roughly $292 to $293 million when its LayerZero bridge was drained. At the time, it was the largest single DeFi exploit of the year. The attack hit rsETH, Kelp's liquid restaking token.

Within hours:

• Aave froze its rsETH markets
• SparkLend and Fluid followed
• AAVE's token dropped about 16% as people rushed to cut rsETH exposure

The point of failure was the bridge that moved rsETH between chains, not the core restaking mechanism itself.

That incident, plus the Drift Protocol exploit (widely reported around $285 million) about 18 days earlier, helped push April 2026 loss estimates toward about $635 million across roughly 28 exploits, according to industry roundups such as Phemex and legal analysis from Travers Smith. Confirm latest tallies on DefiLlama hacks.

The lesson is not "restaking is broken." The lesson is that every extra layer (LST, restaking, LRT, cross-chain bridge) is a separate attack surface. Liquid restaking tokens stack several of those layers at once.

Step-by-Step: Approaching Restaking More Safely

1. Know what you are exposed to. Restaking is not one risk. It is Ethereum validator risk, plus AVS-specific slashing risk, plus bridge and peg risk if you hold an LRT.
2. Separate restaking from liquid restaking tokens. Holding restaked ETH directly is a different profile than holding an LRT that needs a bridge to stay pegged and usable.
3. Check which AVSs your ETH is securing. More AVSs often means more yield and more slashing conditions. Read what each one actually does before treating "more yield" as free upside.
4. Watch LRT depeg risk in stress. The Kelp incident showed how fast a peg can break and spill into lending markets that accepted the token as collateral.
5. Size it like a leveraged position. There is real upside, and there are more ways to lose principal than with plain liquid staking.

FAQ: EigenLayer Restaking

Is restaking the same as regular staking?

No. Regular staking secures Ethereum and earns Ethereum's base validator reward. Restaking reuses that staked position to also secure extra services, for extra yield and extra slashing risk.

What actually failed in the Kelp DAO hack?

The exploit hit Kelp's LayerZero bridge infrastructure, not the core restaking or slashing system. The extra layer (bridges and LRTs) was the weak link, not the base idea.

Should beginners avoid restaking entirely?

Not always. But beginners should know restaking is more complex and more risk-layered than plain staking. Size positions carefully, especially anything involving a liquid restaking token.

Does more yield always mean more risk in restaking?

Usually yes. Extra yield pays for extra slashing conditions and, for LRTs, bridge and peg risk. It is rarely free return.

What is an AVS in EigenLayer?

An Actively Validated Service is an extra network or service (oracle, bridge, data layer, and so on) that uses restaked ETH for economic security instead of bootstrapping its own validator set.

Bottom Line

EigenLayer restaking turned staked ETH into a shared security layer for new services. The yield stacking is real. So is the risk stacking.

Base restaking is already more complex than plain staking. Liquid restaking tokens add bridge and peg risk on top. April 2026 made that clear in public.

If you use restaking, treat every AVS and every LRT as a separate decision, not a free upgrade to your staking APY.
