What Is Restaking? Reusing Staked ETH for Extra Yield

Restaking is a mechanism that lets you reuse ETH that is already staked on Ethereum to also secure additional protocols, earning a second layer of rewards on top of base staking yield. Instead of capital sitting idle once it secures the network, restaking points that same economic weight at new services — and in return exposes it to new validator slashing conditions. In practice you either restake natively or, more commonly, deposit liquid staking tokens into a restaking protocol such as EigenLayer. The trade-off is simple: more yield, more risk.

What Restaking Means in Plain Terms

When Ethereum moved to Proof of Stake, securing the network required locking ETH into a staking contract. That ETH does one job: it backs honest validation, and it can be slashed if a validator misbehaves. Restaking asks a sharper question — if this capital already carries economic security, why can it only secure one network?

Restaking answers that by letting the same staked ETH (or a token representing it) be committed to additional systems that need security but cannot easily bootstrap their own validator set. Each of those systems adds its own slashing rules. So a single deposit can now back several services at once, multiplying both potential rewards and potential penalties.

How Restaking Actually Works

Most users never run hardware. The dominant path routes through liquid staking and then a restaking layer. Here is the typical flow:

1. Stake ETH through a liquid staking protocol and receive a liquid staking token (an LST) that represents your staked position.
2. Deposit the LST into a restaking protocol, which pools it with thousands of other deposits.
3. Opt in to services — the restaking protocol allocates your pooled security to the additional networks or modules you choose to back.
4. Earn layered rewards from base staking plus the services you secure, minus any slashing if a backed service penalizes misbehavior.
5. Exit by withdrawing through the restaking protocol and unwinding the LST, subject to each layer's unbonding rules.

Advanced users can instead point their own validator's withdrawal credentials directly at a restaking protocol (native restaking). It is more hands-on and resource-heavy, which is why the LST route dominates.

Liquid Staking vs. Restaking

These two concepts are constantly confused, but they sit at different layers. Liquid staking unlocks your staked capital so it stays usable in DeFi; restaking takes that already-staked capital and rents its security out to other networks.

Liquid staking is the building block; restaking is built on top of it. You can liquid-stake without restaking, but you generally cannot restake without first holding something like an LST.

A Worked Numeric Example

Suppose you stake 32 ETH and base Ethereum staking yields roughly 3.5% annually. That is about 1.12 ETH per year from securing Ethereum alone.

Now you restake the position and back two additional services paying an estimated 2% and 1.5% in additional rewards on the same capital. Layered on top, that adds roughly 3.5% more — another ~1.12 ETH — bringing your gross annualized rate to about 7%, or ~2.24 ETH per year.

The catch: your slashing surface roughly tripled. A serious fault on any one backed service could slash a chunk of principal. If a single severe event slashed even 5% of your stake (1.6 ETH), it would erase more than a full year of that extra yield. Restaking math only works when expected extra reward clearly exceeds the expected cost of compounded slashing — and that is a judgment call, not a guarantee.

Risks and Pitfalls You Should Weigh

Restaking concentrates several risks that beginners often underestimate:

• Compounded slashing. Every backed service adds penalty conditions. A fault you did not directly cause can still cost you principal.
• Smart contract risk. Restaking stacks multiple smart contract layers; a bug in any one can cascade.
• Liquidity and de-peg risk. LSTs can trade below their underlying value during stress, and restaked positions may be harder to exit quickly.
• Complexity and integration risk. More moving protocols means more surfaces for unforeseen interactions and failures.
• Systemic concentration. If a large share of staked ETH restakes through one layer, a failure there could ripple across many networks at once.
• Governance and regulatory risk. Protocol parameter changes or shifting rules can alter your risk profile after you have committed.

Notable Restaking Protocols

The category is anchored by EigenLayer, which pioneered letting stakers reuse ETH security for additional services. A surrounding ecosystem of liquid restaking protocols issues its own receipt tokens so deposits stay composable across DeFi, and several offer low-barrier entry so smaller holders can participate. When evaluating any of them, weigh security track record, supported assets, realistic net yield after risk, exit mechanics, and how transparently the protocol curates which services your capital backs.

COINOTAG Perspective

We view restaking as one of the most consequential — and most over-marketed — primitives in DeFi. The capital-efficiency case is real: idle security being rented out is a genuinely elegant idea. But headline "points" and stacked APYs routinely obscure that you are selling insurance on multiple protocols at once. Our guidance: treat the base staking yield as your floor, treat every basis point above it as compensation for added slashing surface, and never restake more than you can afford to see slashed. For most newcomers, plain staking or simple liquid staking is the safer on-ramp before layering on restaking complexity.

If you want the prerequisites first, start with how to stake Ethereum and a primer on liquid staking, then return to restaking once the underlying mechanics feel comfortable.
