What Is Restaking? Extra Yield Layered on Extra Risk
CryptoRebateHub Editorial Team
Restaking lets you take already-staked assets (like the receipt from staked ETH) and "lend" their security to other protocols, earning a second layer of yield on top of base staking rewards. The cost is stacked risk: a wider surface for slashing. Here is how it works, where the yield comes from, and the new risks.
To understand restaking, first understand staking: you lock coins to help a network stay secure, earning rewards. Restaking goes one step further — it reuses assets that are already staked.
The problem it solves
Ethereum has a huge amount of staked ETH securing the main network. But new protocols — bridges, oracles, layer-2s — need their own security guarantees, and bootstrapping a staking set from scratch is hard. Restaking's idea: let already-staked ETH (and its staking receipts) moonlight as security for these new protocols. The new protocol borrows security; the staker earns an extra service fee.
Where the yield comes from
- Layer one: the original staking rewards (from issuance and fees).
- Layer two: "security rent" paid by the protocols you help secure.
Two layers stacked, so restaking's headline APY tends to beat plain staking.
The risk stacks too — this is the point
Yield isn't free. Restaking's core risk is a wider slashing surface:
- With plain staking, you're only slashed if you break the main network's rules.
- After restaking, every protocol you secure can endanger your principal if it fails (gets attacked, is misconfigured, or triggers its rules). The more you secure, the bigger your exposure.
Plus: smart contract bug risk (more protocols = more code risk), liquidity risk (receipt tokens can trade at a discount), and yield that depends heavily on whether new protocols can keep paying the "rent".
How it differs from ordinary yield
Don't equate restaking's high APY with "safe income". It's fundamentally about renting out your security guarantee to more parties — the yield comes from taking on more responsibility. The higher the APY, the more (and more aggressively) you're usually securing — the same "high yield = high risk" rule as stablecoin yield.
Who it's for and how to approach it
- For: advanced users already staking ETH long-term, who understand smart-contract risk and accept more risk for an extra yield layer.
- Not for: beginners, the risk-averse, or anyone treating it as "risk-free high interest".
If you participate: only commit what you can afford to lose, diversify what you secure, read each protocol's slashing rules, and understand the underlying risks of DeFi.
