Restaking Explained: EigenLayer, Shared Security and Risk
Restaking reuses staked ETH to secure other applications for extra yield. We explain EigenLayer, liquid restaking tokens, the ezETH depeg, rival platforms, and where the SEC now stands.
Staking locks up cryptocurrency to help secure a blockchain and earns a yield for doing so. Restaking takes that same capital and puts it to work a second time, extending its security guarantees to other applications without unwinding the original position. The idea went from a whitepaper to one of the largest categories in decentralized finance in barely two years, pulling in tens of billions of dollars and a long list of warnings from Ethereum’s own researchers.
This explainer covers what restaking is, how EigenLayer turned it into a market, the liquid restaking tokens that brought in retail money, the risks that have already produced one nine-figure liquidation cascade, and where US regulators landed after a friendlier 2025. Prices are in USD, and the regulatory section focuses on the Securities and Exchange Commission (SEC).
What restaking actually means
To stake on Ethereum, a validator locks 32 ETH (or a share of it through a staking pool) as collateral. If the validator behaves, it earns rewards; if it misbehaves, part of that collateral can be slashed. Restaking lets the same staked ETH, or a liquid token that represents it, pledge additional collateral to other protocols called Actively Validated Services (AVSs). Those services borrow Ethereum’s economic security instead of bootstrapping their own validator set from scratch.
The trade is straightforward. Restakers earn extra rewards on top of their base staking yield, and the service gets a large pool of collateral standing behind its rules. The catch is that the restaker now faces additional slashing conditions, one set for every service it backs. The comparison critics reach for is rehypothecation in traditional finance, where the same collateral is pledged against more than one obligation at once.
How EigenLayer built the restaking market
EigenLayer, built by Eigen Labs, is the protocol that turned restaking into a category. It opened restaking deposits on Ethereum mainnet in June 2023 and became fully operational through 2024. Deposits climbed fast: at one point EigenLayer passed Aave to become one of the largest DeFi protocols by total value locked, and it crossed $15 billion in 2024 before peaking near $20 billion.
The EIGEN token followed. EigenLayer opened airdrop claims in May 2024 for an initially non-transferable token, and EIGEN began trading on exchanges in October 2024. The bigger milestone for the design came in 2025, when EigenLayer turned on slashing, the mechanism that lets services actually punish misbehaving operators. Slashing went live on mainnet in 2025, and the team later shipped redistribution, which lets slashed funds be routed to a defined recipient instead of simply being burned, opening the door to lending and insurance use cases.
Liquid restaking tokens, the retail on-ramp
Most users never run a validator or pick operators by hand. They use liquid restaking tokens (LRTs), the restaking version of liquid staking tokens like stETH. A user deposits ETH or a liquid staking token, the protocol restakes it and manages the operator and service selection, and the user receives a tradable token that accrues the combined yield.
Ether.fi is the largest of these, issuing eETH and its wrapped version weETH, and it held onto deposits better than rivals as the broader hype faded. Renzo issues ezETH and Kelp DAO issues rsETH, with Puffer’s pufETH rounding out the field. At the 2024 peak, liquid restaking platforms together approached $8 billion in deposits. LRTs are convenient, but they add a layer of smart-contract and governance risk on top of the restaking risk underneath, a point the next sections return to.
The restaking market by the numbers
EigenLayer still dominates restaking by a wide margin, but its TVL has been a roller coaster. After peaking near $20 billion in 2024, it repriced sharply once slashing arrived and the points-farming incentives wound down, sliding toward the high single digits of billions before recovering into the low double digits in 2026. The table below is a mid-2026 snapshot; figures move daily, and live numbers are tracked on DefiLlama.
| Platform | Native chain | Model | Approx. TVL (mid-2026) |
|---|---|---|---|
| EigenLayer | Ethereum | Curated service onboarding; slashing and redistribution live | ~$12 billion |
| Symbiotic | Ethereum | Permissionless; almost any ERC-20 as collateral | ~$2 billion |
| Karak | Multi-chain | Permissionless; restakes a wide range of assets | ~$0.6 billion |
On the consumer side, a handful of LRT issuers hold most of the deposits. Their TVL overlaps with the platforms above, because LRTs route much of their ETH into EigenLayer and, increasingly, Symbiotic; the figures are not additive.
| LRT protocol | Token | Notes |
|---|---|---|
| ether.fi | eETH / weETH | Largest LRT issuer; expanded into cards and lending |
| Renzo | ezETH | Strategy manager; depegged sharply in April 2024 |
| Kelp DAO | rsETH | Multi-asset restaking with multi-chain reach |
| Puffer | pufETH | Anti-slashing technology and native restaking focus |
What restaked security actually secures
The point of restaking is not yield for its own sake; it is shared security for services that would otherwise have to build their own. These services, the AVSs, cover several categories.
- Data availability layers such as EigenDA, which sell cheaper data throughput to rollups.
- Oracle networks and price feeds that need economic weight behind their reporting.
- Bridges and cross-chain messaging that enforce service-level agreements through slashing.
- Sequencers, co-processors, and other off-chain compute that settles back to Ethereum.
Redistribution widened the menu. Because slashed collateral can now be sent to a specified recipient rather than burned, restaking can underwrite obligations that look more like insurance or lending. An early adopter is a stablecoin protocol that has operators commit to loan terms and post restaked collateral, so a broken commitment can be made good from the slashed funds. In effect, restaked ETH becomes programmable collateral that an application can rent and, if rules are broken, claw back.
The risks: slashing, depegs and rehypothecation
Restaking stacks risks. Every service a restaker backs adds its own slashing conditions, so a single bug in one service can cost collateral that also sits behind everything else. Liquid restaking tokens add market risk on top, because an LRT only holds its peg as long as the market believes it can be redeemed for the underlying ETH.
That is not theoretical. In April 2024, Renzo’s ezETH briefly crashed after the protocol unveiled its token allocation, trading near $700 on some venues as holders rushed to exit positions that could not yet be redeemed directly. Leveraged points farmers were wiped out, and the depeg triggered roughly $60 million in liquidations across lending markets such as Gearbox and Morpho.
The deeper worry is systemic. Ethereum co-founder Vitalik Buterin warned in 2023, in a post titled “Don’t overload Ethereum’s consensus,” that pushing too many high-stakes applications onto the validator set could create pressure to bail them out through a chain fork if one fails badly. Reused collateral, concentrated operators, and complex contracts are the ingredients for correlated failures, which is why critics describe restaking as rehypothecation with the volume turned up.
The competition: Symbiotic and Karak
EigenLayer no longer has the field to itself. Symbiotic, a permissionless restaking protocol that lets any network secure itself with almost any ERC-20 asset, raised $29 million in a round led by Pantera in 2025 and crossed roughly $1.7 billion in deposits within months of launch. Its pitch is flexibility: networks pick their own collateral and their own dispute-resolution, or resolver, system instead of accepting one fixed model.
Karak is the third major name, offering permissionless, multi-chain restaking across a wider range of assets than ETH alone. The competition matters for users because it spreads collateral across rival systems, which can reduce single-protocol concentration but also fragments security and multiplies the smart-contract surfaces a depositor is exposed to.
Where US regulators stand
Staking’s legal status in the United States shifted in 2025. The SEC’s Division of Corporation Finance issued a statement in May 2025 concluding that certain “protocol staking activities” on proof-of-stake networks are administrative rather than entrepreneurial, and therefore are not securities offerings under the Securities Act. A follow-up statement in August 2025 extended similar reasoning to some liquid staking arrangements. That is a sharp turn from the previous administration, which treated staking-as-a-service as a securities issue and extracted a $30 million settlement from Kraken in 2023.
Restaking sits in a grayer zone. The SEC’s relief is keyed to activities it views as ministerial; restaking adds discretionary choices about which services to back and which operators to trust, and liquid restaking tokens wrap all of that into a tradable instrument whose value depends on a protocol’s management. None of the 2025 statements is a binding rule, and they leave open whether actively managed LRTs could still look like investment contracts under the Howey test. Issuers operating in the US should treat the guidance as helpful but not a green light.
What to watch in 2026
Three threads will decide whether restaking matures or stalls. The first is real service demand: slashing and redistribution only matter if AVSs actually pay for security, and 2026 is the year that business model gets tested beyond data availability. The second is risk discipline, including whether LRTs hold their pegs through stress and whether operators stay diversified enough to avoid the correlated failures researchers keep flagging. The third is regulatory follow-through, since the SEC’s softer stance could be written into formal rules or reversed by a future commission.
For now, restaking is a large, volatile, and still-experimental corner of DeFi. It has proven it can attract capital; the open question is whether it can turn that capital into durable, paid-for security without becoming the systemic risk its own critics describe. The figures to watch from here are AVS revenue numbers, which will say more about restaking’s health than deposit totals ever did.
