Restaking lets you reuse already-staked ETH to secure additional protocols simultaneously, earning extra yield on top of base Ethereum staking rewards. EigenLayer pioneered this: you stake ETH on Ethereum (earning ~4% APR), then "restake" that same ETH to also secure EigenLayer-supported services (oracles, bridges, rollups) earning additional rewards (2-10%+ APR). One deposit, multiple security roles, compounded yield.
What Is Restaking?

The short version
Normal staking: you lock 32 ETH to secure Ethereum, earn ~4% APR. That ETH sits there doing only one job. Restaking: you take that locked ETH and use it AGAIN to secure other services built on top of Ethereum (oracles, data availability layers, cross-chain bridges). Those services pay you extra rewards for securing them. Your 32 ETH now does two jobs: securing Ethereum AND securing EigenLayer services. You earn from both.
How It Works
How restaking works (EigenLayer model): (1) You already stake ETH on Ethereum (either solo staking 32 ETH or using a liquid staking derivative like stETH, rETH). (2) You deposit your stake (or staked token) into EigenLayer smart contracts. This is "restaking". (3) EigenLayer assigns your restaked ETH to secure Actively Validated Services (AVS): services that need economic security but don't want to bootstrap their own validator set (examples: oracles, bridges, data availability layers, off-chain compute networks). (4) The AVS pays rewards in their native token or ETH for this security. You earn these rewards ON TOP OF your base Ethereum staking yield. (5) Risk: if you misbehave or the AVS gets exploited, your restaked ETH could be slashed (reduced as penalty). This is the tradeoff: more yield, more slashing risk. Native restaking: you directly restake actual validator ETH (requires running EigenLayer-modified validator software). Liquid restaking tokens (LRTs): protocols like EtherFi, Renzo, Puffer create liquid restaking derivatives. You deposit stETH, receive eETH (EtherFi) or ezETH (Renzo). These tokens auto-compound restaking rewards and are liquid (can be traded or used in DeFi while earning yield). Yield sources: (1) Base Ethereum staking (~4% APR), (2) EigenLayer AVS rewards (variable, 2-15% depending on service), (3) LRT protocol points/airdrops (speculative but historically valuable). Total APY: often 8-20% depending on configuration. Current scale (mid-2024): EigenLayer holds ~4.5M ETH restaked (~$14B), making it one of the largest DeFi protocols by TVL. Risks: slashing risk from AVS failures, smart contract risk (EigenLayer contracts), centralization concerns (a few large operators control most restaked ETH).
Restaking 32 ETH via EigenLayer and earning extra yield
You have 32 ETH staked directly as a solo validator, earning ~4% APR (~1.28 ETH/year). You want to earn more without buying more ETH. You enable EigenLayer restaking: (1) Install EigenLayer sidecar on your validator node. (2) Opt-in to three AVS services: an oracle network, a cross-chain bridge, and a data availability layer. (3) Each AVS pays rewards: Oracle: 2% APR in their token, Bridge: 3% APR in ETH, Data layer: 1.5% APR in their token. (4) Your total yield: 4% (Ethereum base) + 2% + 3% + 1.5% = 10.5% APR on your 32 ETH = ~3.36 ETH/year. You more than doubled your staking income without adding capital. Risks: If the bridge AVS has a bug and you fail to validate correctly, your 32 ETH could be slashed 1-5% (~0.32-1.6 ETH penalty). You accept this risk for the 6.5% extra yield. After one year: your validator earned 3.36 ETH (~$10,000 at $3,000/ETH) vs 1.28 ETH ($3,840) without restaking. Delta: $6,160 extra income, with the tradeoff of additional slashing exposure.
What People Get Wrong
Restaking doubles my staking rewards automatically
No. Restaking earns ADDITIONAL yield from securing other services, but those services pay varying rates (some high, some low). You do not get double base staking yield. Total yield depends on: which AVS you secure, their reward rates, and demand for security. In low-demand periods, extra yield might be only +1-2%. In high-demand: +5-10%+.
Restaking has no additional risks
Restaking adds slashing risks from the AVS services you secure. If an AVS has a bug, gets exploited, or you fail to perform validation duties correctly, your restaked ETH can be slashed (on top of normal Ethereum slashing risks). You are taking on multiple slashing conditions simultaneously. Higher yield = higher risk. Always the case.
EigenLayer is the only restaking protocol
EigenLayer is the largest and first, but alternatives exist: Symbiotic (alternative restaking design), Karak (multi-asset restaking, not just ETH), and protocol-specific restaking (Lido, Rocket Pool exploring native integrations). The restaking primitive is being adopted widely, not exclusive to one protocol.
I need 32 ETH to restake
No. Liquid restaking tokens (eETH, ezETH, rsETH) allow participation with any amount. Deposit $100 of stETH into EtherFi, receive eETH, and you are restaking. No validator operation needed. This is the retail-friendly path. Only native restaking requires running a validator with 32 ETH.

Questions People Also Ask
- Can I unstake restaked ETH whenever I want?
- Depends. Native restaking: follows Ethereum validator exit queue (7+ days minimum). Liquid restaking tokens: more flexible, can sell eETH/ezETH instantly on DEXs for ETH (might trade at slight discount/premium). Withdrawing from the protocol directly: usually 7-day unbonding period + Ethereum withdrawal queue. Less liquid than normal staking, plan accordingly.
- What happens if an AVS I secure fails?
- Your restaked ETH could be slashed (reduced) by the percentage specified in the AVS slashing conditions (typically 1-5% per incident, capped). The slashed ETH compensates users harmed by the failure. This is the economic alignment: you have skin in the game securing the service. Choose AVS carefully based on their security track record and slashing risk parameters.
- Is restaking yield sustainable long-term?
- Debated. Current high yields (8-20%) are partly from airdrop farming (EigenLayer points, AVS token incentives). Once these programs end, yields will normalize to reflect real economic demand for security. Long-term: expect 5-8% total (4% Ethereum base + 1-4% AVS rewards) rather than 15%+. Still better than base staking alone, but not the current boosted rates forever.
- Can I restake on Layer 2s?
- Not yet natively (ETH staking only exists on Ethereum L1). However, you can bridge liquid restaking tokens (eETH, ezETH) to L2s and use them in L2 DeFi protocols. Some L2s are exploring their own restaking mechanisms for securing L2-native services. This is an emerging area as L2 ecosystems mature.
- Do I need to run special hardware for restaking?
- For native restaking: yes, you run a validator with EigenLayer sidecar software (similar resources to regular validator: 32GB RAM, 2TB SSD, reliable internet). For liquid restaking: no, just deposit into protocols like EtherFi or Renzo via their web interface. No hardware, no technical knowledge required. Liquid restaking is the path for 95% of users.
