What Is Restaking & EigenLayer 2026
Restaking is supercharging ETH staking. Ethereum staking earns 3.5% APY. Restaking on EigenLayer earns 15-20% APY by securing other protocols (AVS). EigenLayer has exploded to $23B TVL (April 2026), the fastest-growing DeFi protocol. Liquid restaking tokens like eETH ($4.2B), rsETH ($1.8B), and pufETH ($950M) make restaking accessible. But there's a catch: slashing risk. This comprehensive guide covers how restaking works, why yields are high, and how to evaluate LRTs.
1. What Is Restaking?
Restaking is using staked ETH (or liquid staking tokens) to secure other protocols. Here's the flow: (1) Stake ETH on Ethereum, earn 3.5% APY. (2) Deposit staked ETH into EigenLayer. (3) EigenLayer directs your ETH to Actively Validated Services (AVS). (4) AVS pay you for security, earning you 8-20% additional APY. Total return: 11-23% APY. Catch: if the AVS gets hacked, your ETH gets slashed.
Understanding this concept is a prerequisite for making informed decisions in DeFi. Most losses in crypto come from misunderstanding the fundamentals.
Why Restaking Exists
Ethereum's security is expensive: $100B+ of ETH staked to secure Ethereum. Other protocols (data availability, oracles, sequencers) want similar security. Restaking lets them reuse Ethereum's validator set. Cost: 8-20% APY paid to restakers (cheaper than bootstrapping own security).
2. Ethereum Staking vs. Restaking
Ethereum Staking: 32 ETH minimum, 3.5% APY, no slashing risk (Ethereum is mature). Restaking: any amount (via LRTs), 15-20% APY, slashing risk if AVS breaks. Choose based on risk tolerance. Conservative investors: 100% staking. Aggressive: 50-100% restaking.
3. EigenLayer Mechanics
EigenLayer ($23B TVL, April 2026) is a smart contract platform. You deposit stETH (Lido liquid staking token) or ETH directly. EigenLayer creates a "secondary slashing layer." If the AVS you secure gets slashed, your ETH gets slashed. Operators run validator nodes for AVS. Restakers delegate to operators. Operators earn AVS rewards and share with delegators. EIGEN token (launched March 2026): governance + fee sharing. Current price: $5.80 per token.
Ethereum slashing is automatic (double-sign, attestation failures). Restaking slashing is determined by AVS (amount = AVS design). EigenDA might slash 1% of restaked amount if it goes offline. Or 100% if the AVS is fundamentally broken. This is why restaking requires trust in AVS design.
4. AVS (Actively Validated Services)
AVS are protocols that use EigenLayer for consensus. Major AVS: EigenDA (decentralized data availability, $12B secured), EigenSampler (sampling services), 0xSolidly (oracle), Pumper (sequencer). Each AVS pays restakers differently. EigenDA: 12-15% APY. Emerging AVS: 20-40% APY (higher risk, newer code). Average restaking APY (April 2026): 18%.
5. Liquid Restaking Tokens (LRTs)
LRTs make restaking accessible without running nodes. Ether.fi (eETH, $4.2B), Kelp (rsETH, $1.8B), Puffer (pufETH, $950M). You deposit ETH, get LRT, earn restaking yields (~16-18% APY). LRTs are liquid: trade on DEXs without unstaking. LRT protocols manage operator selection, slashing risk. They take 1-5% fee on yield.
eETH (Ether.fi) - $4.2B TVL
eETH is the largest LRT. Deposit ETH, get eETH shares. eETH earns 16-18% APY. Ether.fi operates validators (runs nodes for AVS). Charges 10% fee on validator rewards. APY after fees: 14-16%.
rsETH (Kelp) - $1.8B TVL
rsETH by Kelp. Similar to eETH but with different operator set. APY: 15-17% after fees. Kelp focuses on risk diversification (multiple AVS delegations).
6. Restaking Yield & Returns
Restaking yields come from: (1) Ethereum base layer staking (3.5%), (2) AVS rewards (12-20%), (3) MEV (maximum extractable value, 0.5-2%). Total: 16-22% APY. Some LRTs offer boosted APY (22-30%) during launch periods, but this unsustainable. After 12-24 months, expect yields to normalize to 12-16% as competition increases.
7. Slashing Risk & Mitigation
Slashing happens if an AVS fails or gets hacked. Example: EigenDA if consensus is broken, stakers get slashed. Amount: 1-100% depending on AVS design. Mitigation: (1) diversify across multiple AVS, (2) choose audited AVS only, (3) start with small amounts, (4) use LRTs (they do diversification for you).
8. LRT Comparison Table
| LRT | TVL | APY | Underlying | Governance |
|---|---|---|---|---|
| eETH (Ether.fi) | $4.2B | 16-18% | stETH + ETH | EFI token |
| rsETH (Kelp) | $1.8B | 15-17% | stETH + cbETH | KELP token |
| pufETH (Puffer) | $950M | 14-16% | Puffer validators | PUF token |
9. EigenLayer Growth & TVL
EigenLayer TVL: $8B (June 2024) → $23B (April 2026). 3x growth in 10 months. It's the fastest-growing DeFi protocol. Reason: high yields + Ethereum validator set backing. EIGEN token launched March 2026, distributed to early users. Price: $5.80 per token.
10. Future: EigenDA & Beyond
EigenDA is restaking's killer app: decentralized data availability. Ethereum dapps and L2s use EigenDA for cheaper data storage (vs. posting to Ethereum). This is why EigenDA has $12B secured—it's genuinely useful. Future AVS: decentralized oracles, sequencers, proof systems. Restaking will likely become standard infrastructure layer (like staking).
FAQ
Should I restake?
High yield + smart contract risk. Conservative: 30% restaking/70% staking. Aggressive: 100% restaking (for extra yield). Start small.
What if eETH gets slashed?
Your eETH balance decreases (shares burned). If 1% slash, your 10 eETH becomes 9.9 eETH. No separate slashing event; it's automatic.
Can I unstake from EigenLayer?
Yes, instant. Sell eETH on Uniswap. Or redeem eETH for ETH via Ether.fi (1-7 day delay for validators to exit).
Which LRT is safest?
eETH (largest, most audited). Then rsETH. pufETH is new (more risk). For maximum safety, don't restake.
Will restaking yields drop?
Likely. As TVL increases, per-staker rewards decrease. Current 18% APY may drop to 8-12% by 2027. High yields unsustainable.
Is EigenLayer regulated?
Unregulated (DeFi). MiCA may affect it in EU. US regulation unclear but likely no issues (it's infrastructure, not a token offering).
