What Is Restaking? EigenLayer, LRTs and the Risks Explained
Restaking lets staked ETH secure more than one network at once, and it has grown into a multibillion dollar slice of DeFi. Here is how it works, who leads it, and why critics urge caution.
Staking secures a blockchain. Restaking asks a sharper question: if your capital is already locked up to keep Ethereum honest, why should it not earn a second fee by helping to secure other systems at the same time? That single idea turned restaking into one of the most talked about corners of decentralized finance, pulling in billions of dollars of deposits, a wave of new tokens, and a long argument about whether the industry is building something useful or stacking risk on top of risk. This guide explains what restaking is, how it works, who the major players are in 2026, and where the danger sits.
What restaking actually is
Restaking is the practice of taking ETH that is already staked, or a token that represents staked ETH, and pledging it a second time to back additional services. Those services pay rewards for the extra security, and in return the restaked capital can be slashed (partially confiscated) if an operator misbehaves. The pitch is capital efficiency: one pool of bonded ETH can underwrite many systems instead of each new network having to bootstrap its own token and validator set from scratch.
The term was popularized by EigenLayer, which launched on Ethereum in 2023 and built the first large market for what it calls shared security. Before restaking, a new data availability layer, oracle, or bridge had to convince investors to buy a fresh token and stake it. Restaking lets that project rent security from Ethereum’s existing stakers instead, which is faster and, in theory, harder to attack.
From staking to restaking: the four layers
It helps to picture restaking as the top of a ladder the industry has been climbing for years. Plain staking bonds ETH to run a validator. Liquid staking, dominated by tokens such as Lido’s stETH, hands you a tradable receipt so your capital is not frozen. Restaking pledges that staked position again to extra services. Liquid restaking then wraps the whole arrangement in a token you can move around DeFi while it earns layered rewards.
| Layer | What you lock | What you hold | Main added risk |
|---|---|---|---|
| Staking | 32 ETH as a validator | Nothing tradable; ETH is bonded | Slashing for validator faults |
| Liquid staking | Any amount of ETH | An LST such as stETH | Token depeg, issuer risk |
| Restaking | Staked ETH or an LST | A claim inside a restaking protocol | Extra slashing from each service secured |
| Liquid restaking | ETH or an LST, via a manager | An LRT such as eETH or ezETH | All of the above, plus manager and contract risk |
Every rung adds yield and removes friction, and every rung stacks another layer of risk on the same underlying ETH. A single deposit can end up exposed to a validator, a staking token, a restaking protocol, and several services at once. That trade, more yield in exchange for more layered risk, is the whole story of restaking, and it is worth keeping in mind through the rest of this guide.
Operators, AVSs and how the plumbing works
Three roles make restaking work. Restakers supply the capital, either by restaking ETH straight from a validator (native restaking) or by depositing a liquid staking token. Operators run the actual software for the services being secured and take a cut of the rewards. The services themselves are known on EigenLayer as Actively Validated Services, or AVSs: data availability layers, cross chain bridges, oracle networks, and a fast growing list of so called verticals aimed at decentralized artificial intelligence and offchain computation.
A restaker delegates to an operator, the operator opts into the AVSs it wants to support, and each AVS sets the conditions under which stake can be slashed. The economic logic is simple: an attacker would need to control enough restaked ETH to break a service, and doing so would cost them a slashed fortune. Restakers, in turn, are betting that operators stay honest and that the services they back are soundly designed.
How big restaking is in 2026
Restaking grew at a startling pace. The sector peaked near $20 billion in total value locked during the 2024 mania, then cooled along with the rest of DeFi. As of June 2026 the category tracks around $8 billion across all protocols, according to DefiLlama, though the figure is slippery: restaked assets are easy to double count, so many trackers record the underlying ETH once at the staking layer and discount it again at the restaking layer.
EigenLayer, now branded EigenCloud, remains the dominant venue, with roughly $4 billion locked on its own contracts. Its EIGEN token trades near $0.24, for a market capitalization of about $180 million, per CoinGecko, far below the valuations implied at the peak of the hype. The foundation behind the protocol spent late 2025 reworking incentives to reward active users and steer emissions toward services that actually generate fees, CoinDesk reported, a sign the market has moved from paying for deposits to paying for usage.
The contenders: EigenLayer, Symbiotic and Karak
EigenLayer no longer has the field to itself. Symbiotic, which reached mainnet in January 2025, is the most serious challenger. It is permissionless and asset agnostic, accepting most ERC-20 tokens (including wrapped Bitcoin) as collateral rather than ETH alone, and it added ideas such as resolvers for dispute arbitration and slashing insurance vaults that let third parties underwrite risk. Karak, another multi asset protocol, holds a smaller slice of the market.
| Protocol | Mainnet | Collateral | Slashing model | Position |
|---|---|---|---|---|
| EigenLayer (EigenCloud) | 2023 | ETH, LSTs, EIGEN | Operator sets; slashing and redistribution live | Clear market leader |
| Symbiotic | January 2025 | Most ERC-20s, including wrapped Bitcoin | Resolvers and slashing insurance vaults | Largest challenger |
| Karak | 2024 | Multiple assets and stablecoins | Permissionless, operator based | Smaller share |
The headline TVL numbers for these challengers swing wildly between trackers, for the same double counting reasons noted above, so treat any single figure with caution. Symbiotic, for example, has been reported anywhere from a few hundred million dollars to well over a billion depending on the methodology used. What is clear is the direction of travel: restaking is becoming a competitive market for security rather than one protocol’s product.
Slashing and redistribution: enforcement gets real
For its first two years EigenLayer collected deposits without the one feature that makes its model credible: the ability to actually punish bad operators. That changed in 2025. Slashing went live on mainnet in April 2025, making the protocol feature complete and finally putting restaked ETH at genuine risk if an operator breaks the rules of a service it secured, the team wrote.
A few months later the protocol added redistribution, which lets slashed funds be repurposed inside the ecosystem instead of simply being burned, according to EigenCloud. That opens the door to use cases such as onchain insurance and lending, where a slashed bond can compensate a victim directly. It also raises the stakes, because real penalties mean restakers can now lose money to events that have nothing to do with Ethereum itself. In practice a restaker now has to trust not only Ethereum, but every operator and every service in the chain of claims sitting above their deposit.
When restaking breaks: the Kelp DAO exploit
The risks stopped being theoretical in April 2026. Attackers linked to North Korea’s Lazarus Group drained about $292 million from Kelp DAO, whose rsETH is one of the larger liquid restaking tokens, CoinDesk reported. The flaw was not in Kelp’s core contract. The attackers fed false data to a cross chain bridge that relied on a single verifier, tricking the system into minting roughly 116,500 rsETH on Ethereum with nothing backing it.
Because that bridge held reserves backing rsETH across more than 20 networks, the loss broke peg assumptions far beyond the original chain and pushed lending markets including Aave and SparkLend to freeze the token, an analysis by Chainalysis found. The episode was a blunt reminder that a liquid restaking token is only as safe as every bridge, oracle, and configuration choice sitting underneath it, and that restaked collateral can become a contagion channel into the wider lending market.
The systemic risk debate
Critics warned about exactly this kind of fragility early. In May 2023, before restaking had real scale, Vitalik Buterin published an essay against overloading Ethereum’s consensus. His core distinction still frames the debate: the dual use of staked ETH is, in his words, fundamentally fine, but trying to recruit Ethereum’s social consensus to bail out an external application is not.
The fear is cascading slashing. If a large, poorly designed service fails and slashes a big slice of restaked ETH at once, the damage could spill into Ethereum’s own validator set, and stricken projects might lobby for a chain fork to recover their funds, dragging the base layer into disputes it was never meant to settle. Supporters counter that opt in operator sets, capped exposure, and insurance style vaults keep the blast radius contained. The Kelp incident suggested both sides have a point: the damage was severe, yet it stayed inside DeFi rather than threatening Ethereum consensus.
Where regulators stand
For United States readers the legal picture is improving but unfinished. In May 2025 the SEC’s Division of Corporation Finance stated that certain protocol staking activities do not amount to securities transactions, and in August 2025 it extended similar comfort to certain liquid staking activities. Both statements were widely read as a green light for staking businesses that had spent years in limbo.
Restaking, however, was pointedly left out. A joint SEC and CFTC interpretation issued in March 2026 broadened the official taxonomy of crypto assets but did not address restaking, leaving arrangements with discretionary management or layered rewards in a gray zone. For now, builders and institutions are treating restaking as legal but unsettled, which is one reason much of the activity still sits with crypto native protocols rather than regulated custodians.
The bottom line
Restaking is one of the more genuinely new ideas Ethereum has produced since liquid staking, and the demand it serves is real: bridges, oracles, data layers, and AI verification networks all need trust they cannot easily build alone. But the model concentrates risk in ways the industry is still learning to measure, and the rewards have compressed as the hype faded. Anyone weighing an LRT for yield should read the fine print on which services back their capital, how slashing is handled, and what bridges sit in the path. Restaking turned trust into a reusable asset; the open question for the rest of 2026 is how many times that trust can be lent out before something snaps.
