Restaking takes capital that is already staked securing Ethereum and pledges it again to secure additional services, earning a second stream of rewards on the same coins. EigenLayer pioneered the category on Ethereum, holds about $7.1 billion as of 2 October 2026, per DefiLlama, and spawned an ecosystem of liquid restaking tokens, rivals and a Bitcoin cousin. The pitch is capital efficiency, one asset earning twice. The physics is that one asset is also liable twice, and after two years of airdrop-driven hype the honest version of this explainer is finally possible, because the rewards and the penalties are both live now.
Here is how restaking actually works, what it pays once the points era is stripped out, and the risk stack that makes it the most layered form of staking risk there is.
How restaking works
Start with ordinary staking. ETH locked with validators secures Ethereum and earns issuance, the mechanics our staking primer covers. Restaking, per EigenLayer's documentation, adds what it calls a marketplace for trust with three roles. Restakers deposit native ETH, liquid staking tokens or other assets into EigenLayer's contracts. Operators run the actual software. And services, which EigenLayer calls AVSs, third-party networks like oracles and data layers that rent Ethereum-grade security instead of bootstrapping their own validator sets, pay rewards when the work is done properly and slash stake when commitments are broken.
The elegance is real. A new oracle, data layer or bridge can draw on pooled restaked collateral from day one, with the actual security depending on its operator set, collateral mix and slashing design, and stakers monetise security capacity they were already providing. The same elegance is the risk, because the coins backing your liquid staking position are now also collateral for however many services your operator signed up to, each with its own rules about taking them.
Most users touch all this through liquid restaking tokens, LRTs, which do for restaking what liquid staking tokens did for staking, wrap the locked position in a tradable receipt. Ether.fi alone holds over $5 billion, per DefiLlama, and the category's token mechanics, peg behaviour and exit queues mirror the LST playbook with one more protocol layer underneath.
The ecosystem in late 2026
EigenLayer remains the centre at roughly $7.1 billion, well below its 2024 hype peak, which is itself informative, capital left when the airdrop meta ended and what remains is there for the actual economics. Symbiotic runs the main rival marketplace at about $0.5 billion, and Babylon applies the same idea to Bitcoin at $3.5 billion, all per DefiLlama on 2 October 2026, letting BTC secure external chains from self-custodial locks, the design our Bitcoin staking breakdown covers in depth. Restaking, in other words, graduated from an Ethereum experiment to a cross-chain security industry, just a smaller one than its 2024 marketing promised.
What it actually pays
The restaking return is a stack. Base Ethereum staking yield sits at the bottom, around the low single digits that the protocol pays everyone. AVS rewards sit on top, paid in various tokens by the services renting security, and this layer has been persistently thinner than the 2024 points frenzy implied, since most AVSs are young businesses with modest budgets. Much of the double-digit effective return advertised during the 2024 boom came from points and airdrop expectations rather than service revenue, and that component shrank as the token distributions completed.
The sober way to read it today is base staking yield plus a variable service premium, modest in the post-points era, paid partly in volatile tokens, in exchange for a materially expanded risk surface. Whether that trade clears depends entirely on the next section.
The risk stack, plainly
Slashing is live and broader than most holders assume. Per EigenLayer's slashing documentation, slashed funds are burned or redistributed, and the protocol is deliberately flexible, AVSs may design their own conditions and, in the docs' own words, have flexibility to slash for any reason, with the system encouraging rather than enforcing legibility. Your protection is operator selection and the safety delays, not a guarantee that only provable misbehaviour gets punished.
Then the stack beneath. Smart contract risk multiplies across layers, Ethereum staking, the LST, EigenLayer, the LRT wrapper, each a separate codebase. Correlation risk concentrates, one operator fault can hit stake pledged across several services at once. LRT liquidity can reprice in stress exactly as stETH once did, with a thinner market. And the whole structure is, functionally, the security version of rehypothecation, the lending practice of promising the same collateral to multiple claimants that our rehypothecation explainer dissects, which works until the day everyone wants the collateral back at once. Restaking does it transparently and with code, which is genuinely better, and the economic shape rhymes.
None of this makes restaking a scam. It makes it a leveraged security market for participants who can evaluate operators, read AVS slashing conditions and absorb a correlated loss. That is a narrower audience than the one that bought LRTs for points in 2024.
Where it fits for an ordinary holder
The honest sizing question is whether the variable premium over plain staking pays for the extra layers of risk, and for passive ETH holders that math has looked thin since the airdrops ended. Plain staking or liquid staking covers the base yield with fewer failure modes. Restaking earns its place for holders who actively want the security-marketplace exposure and will do the operator homework.
Managed strategies are the third lane, for holders who want ETH productive without operating any of this. EarnPark pays up to 15% APY on ETH as of October 2026 at the top of its range, from a high-risk trading strategy with monthly settlement, with a medium-risk on-chain lending strategy settling monthly and a low-risk market-making strategy paying daily with a 30 day bonding exit beneath it, published base rates every account gets holding zero PARK. Those carry platform and strategy risk rather than slashing risk, a different stack to evaluate rather than a smaller one, and each strategy page names its source and terms so the evaluation is possible. Choosing plain staking and skipping both restaking and managed yield is also a defensible answer, and for the allocation you deliberately decide to put to work, the start earning flow covers the mechanics.
FAQ
What is restaking in simple terms?
Using already-staked crypto as security collateral for additional services at the same time, earning extra rewards from those services on top of base staking yield, while also being exposed to their penalties. EigenLayer pioneered it on Ethereum and Babylon brought the concept to Bitcoin.
Is restaking safe?
It is staking with more layers of both reward and risk. Slashing on EigenLayer is live, AVSs set their own conditions, and liquid restaking tokens add contract and liquidity risk on top of the LST stack. The major protocols are serious engineering efforts, and the risk surface is genuinely larger than plain staking.
What is the difference between EigenLayer and Lido?
Lido is liquid staking, your ETH secures Ethereum and you receive stETH. EigenLayer is restaking, staked ETH or LSTs get pledged again to secure additional services for extra rewards. Many users stack them, staking through Lido and restaking the stETH, which compounds both the yield and the risk layers.
How much does restaking yield?
Base Ethereum staking yield plus a variable AVS premium that has run modest since the points era, partly paid in service tokens. Much of the double-digit effective return advertised in 2024 came from points and airdrop expectations rather than service revenue, and shrank as those distributions completed.
