What Is Restaking? Explaining Crypto's Newest Yield Layer

Restaking is the practice of reusing already-staked crypto assets (typically staked ETH) to simultaneously provide economic security to additional protocols and networks, in exchange for extra yield on top of the base staking reward — while also taking on additional slashing risk from each service secured.

Why restaking exists

Proof-of-stake networks like Ethereum secure themselves by having validators lock up capital that can be destroyed ("slashed") if they misbehave. That works well for the base chain, but it means every new network, oracle, bridge, or middleware service that wants similar cryptoeconomic security has traditionally had to bootstrap its own separate pool of staked capital and its own validator set from scratch — slow, capital-intensive, and fragmenting security across many smaller, weaker pools.

Restaking's core insight: capital already staked and securing Ethereum can, with the owner's consent, be pledged as additional collateral securing other services simultaneously. Instead of every new middleware protocol bootstrapping fresh capital, it can borrow security from Ethereum's existing, much larger staked base. This turns Ethereum's staked ETH into a shared security resource rather than a single-purpose one.

How restaking actually works

1. Base layer staking — a user stakes ETH (directly or through a liquid staking token) to secure Ethereum as normal.
2. Opt-in to restaking — the user (or the liquid staking token's smart contract) opts that stake into a restaking protocol, which lets it also back the security of additional services.
3. Service operators — independent operators run the software required by these additional services (often called Actively Validated Services, or AVSs) — things like oracle networks, bridges, data availability layers, or specialized rollups.
4. Additional slashing conditions — each service the restaked capital secures defines its own conditions under which a portion of the restaked stake can be slashed for misbehavior specific to that service.
5. Additional yield — in exchange for taking on this extra risk, the restaker earns additional rewards paid by the services being secured, stacked on top of ordinary staking yield.

What restaking is really trading off

The appeal is straightforward: more yield on capital that's already locked up and earning a base staking return. The trade-off is just as straightforward: each additional service you restake into adds a new, independent way your capital can be slashed. A bug or malicious action related to any one AVS you're backing can result in a penalty, even if your behavior on the base Ethereum chain was flawless.

This compounding of risk is the single most important thing to understand before restaking: you are not just multiplying yield, you are multiplying the number of independent failure modes your capital is exposed to.

Restaking vs. plain liquid staking

Factor	Plain liquid staking	Restaking
What's secured	Ethereum base layer only	Ethereum plus one or more additional services
Yield	Base staking reward only	Base reward plus additional service rewards
Slashing conditions	Ethereum protocol rules only	Ethereum rules plus each AVS's own rules
Risk surface	Single, well-understood	Multiplies with each service opted into
Maturity	Long track record	Newer, less battle-tested

Liquid restaking tokens

Similar to how liquid staking tokens represent staked ETH while remaining tradable, liquid restaking tokens (LRTs) represent a restaked position, letting holders use that position elsewhere in DeFi (as collateral, in liquidity pools) while the underlying capital continues earning restaking rewards. This adds a further layer of smart contract and operator risk on top of the restaking risk itself — see our dedicated explainer on liquid restaking tokens for details, and how leading restaking platforms compare in our EigenLayer vs. Symbiotic comparison.

Risks worth taking seriously

• Compounding slashing risk — each AVS is an additional way to lose principal, and the conditions vary by service and aren't always as battle-tested as Ethereum's own slashing rules.
• Operator risk — you're often trusting a node operator to correctly run software for multiple services; operator error can trigger slashing regardless of your own behavior.
• Smart contract risk — the restaking protocol itself, plus any liquid restaking token wrapper, adds contracts that could contain bugs.
• Correlated risk during stress — because restaked capital underpins multiple services at once, a severe incident in the restaking ecosystem could affect many services simultaneously.

Bottom line

Restaking turns already-staked ETH into a shared security resource for the broader ecosystem, offering extra yield in exchange for extra risk. It's a genuinely useful innovation for bootstrapping new networks' security, but it isn't free yield — it's compensation for taking on additional, less-tested slashing conditions layered on top of ordinary proof-of-stake risk. Understand exactly which services your restaked capital secures, and check current restaking yields against the risk on the yield dashboard before committing.
