Restaking in 2025: The Complete EigenLayer & AVS Guide (Rewards, Slashing Risks, Best LRTs)
Restaking is the year’s hottest but most misunderstood theme in crypto security. This guide explains restaking from first principles: how EigenLayer uses Ethereum economic security to bootstrap new networks known as Actively Validated Services (AVSs), how rewards are generated, what slashing really means in practice, and how to approach liquid restaking tokens (LRTs) without blowing up your risk budget. We keep the language practical, the diagrams simple, and the checklists actionable.
Why restaking matters in 2025 (and why most people are still confused)
Proof-of-Stake (PoS) gave blockchains a clean way to secure networks with economic collateral. Ethereum’s validator set is the largest and most battle-tested PoS security budget on earth. Restaking tries to reuse that economic security for new networks and services, instead of each new project bootstrapping its own validator set and token incentives from scratch. The pitch is elegant: “borrow Ethereum’s security, pay it back with fees and rewards.”
The catch? Coordination and risk. If the same collateral backs multiple things at once, a failure in one place can cascade. Slashing becomes multidimensional, operators and policies matter more than APYs, and the fine print of each Actively Validated Service (AVS) determines whether your rewards are sustainable or just another leveraged carry trade.
What is restaking? The plain-English model
Restaking means pledging staked ETH (or tokens representing it) to secure additional networks or protocols beyond Ethereum’s base chain. The additional networks are called AVSs , anything that needs a set of validators with skin in the game: data availability layers, oracles, shared sequencing, coprocessors, bridges, MEV services, and more.
Instead of building a tiny new validator set with weak economics, an AVS can say: “If you validate us incorrectly, you can be slashed on your restaked ETH.” That makes attacks more expensive and aligns incentives with Ethereum’s strongest security guarantees. As a restaker you earn fees/incentives from AVSs in addition to your base ETH staking yield.
The EigenLayer stack: restakers, operators, and policies
EigenLayer is the flagship restaking framework on Ethereum. It provides the plumbing that connects collateral (your restaked ETH or LSTs) to services (AVSs) through a marketplace of operators. At a high level:
- Restakers deposit ETH/LSTs or opt in natively. They delegate their “restaked voting power” to an operator.
- Operators run infrastructure for one or more AVSs. They advertise track records, supported AVSs, fees, and runtime setups.
- AVSs publish slashing conditions, verification code, and payment models. They plug into EigenLayer’s contracts to enforce penalties and downstream reward distribution.
Policies matter. Every AVS defines what counts as a violation and how penalties propagate. Some AVSs only opt-in for informational penalties at first (e.g., reputation), while others can trigger on-chain slashing that affects your underlying restaked collateral. Always read the AVS terms and your operator’s configuration before delegating.
Actively Validated Services (AVSs): what they are and why they pay you
An AVS is any network function that needs a set of actively verifying nodes with economic consequences. Examples include:
- Data Availability (DA): services that guarantee data blobs are published and retrievable.
- Shared Sequencing: ordering transactions for L2s/rollups with liveness guarantees.
- Oracles & Coprocessors: external computation and data feeds with verifiability.
- Bridging/Finality gadgets: cross-chain message verification anchored by slashable stake.
- MEV & ordering markets: rules-based block building, censorship resistance, and ordering fairness experiments.
AVSs pay operators/restakers using a mix of fees (in ETH, stablecoins, or AVS tokens) and incentives (emissions, points, airdrops, or long-term revenue share). The sustainability of that mix is the single biggest driver of whether a restaking reward is durable or a short-lived subsidy.
Rewards & yield math: where the extra % actually comes from
Think of restaking yield as a stack of components. Your base ETH staking reward remains whatever it is for validators/LSTs. Restaking adds a new layer:
Back-of-envelope formula
Net APY ≈ Base ETH Staking APY
+ Σ(AVS_Fees_to_Restakers – Operator_Fee – Protocol_Fee)
+ Incentives (time-limited)
– Impermanent Costs (withdrawal queues, LRT depeg risk, slashing probability × penalty)
The fewer assumptions you need to make about incentives and liquidity, the more trustworthy the APY. A fee-paying AVS with mature demand is better than points-only.
What changes your realized yield
- Operator fee: many operators take a cut of AVS rewards for running infrastructure. Compare published fee schedules.
- Protocol fee: the LRT or restaking manager may take a small protocol fee.
- Utilization: if an AVS has caps or limited tasks, only some delegated stake actually earns at the headline rate.
- Payment asset: getting paid in the AVS’s native token introduces price risk; stablecoin/ETH fees are cleaner.
- Liquidity & queues: for LRTs, exit queues and withdrawal delays create opportunity cost during risk-off periods.
Slashing & correlated risk: the part you must not skip
Slashing is a penalty applied to your restaked collateral if your operator (or your validator in native restaking) violates an AVS rule, for example, equivocating on data availability or failing a signed obligation. In restaking, penalties can stack: one mistake may harm both the AVS and your underlying ETH position.
Key risk concepts
- Correlation: running the same client stack across AVSs increases the chance of a single bug slashing many delegations at once.
- Policy clarity: AVSs define violation types, evidence standards, and appeals. Prefer AVSs with transparent on-chain policies and public code.
- Operator choice: an operator’s uptime, diversity (clients/clouds), and monitoring posture are your first line of defense.
- Opt-in scope: you can delegate to operators who only run certain AVSs. Narrow scope = lower correlated risk.
- LRT leverage: stacking LRTs on top of LSTs increases contractual layers; know who bears the penalty and how it propagates.
Bottom line: Restaking is not “free APY.” Treat it as secured lending of your trust. Price the extra yield against the specific slashing surface you’re assuming.
Liquid Restaking Tokens (LRTs): convenience vs. complexity
LRTs package restaking for regular users. You deposit eligible LSTs or ETH, the protocol restakes with approved operators, and you receive a liquid token (e.g., XYZ-LRT) you can use in DeFi. Benefits include fractional access, auto-compounding, and simple delegation. The trade-offs are additional smart-contract risk, protocol fees, potential depeg/liquidity during stress, and governance choices you don’t control.
| Dimension | What to Check | Why it Matters |
|---|---|---|
| Collateral & Custody | Accepted LSTs, custody model, upgrade keys, admin timelocks | Determines security inheritance and who can change the rules |
| Operator Set | Number, diversity, historical uptime, client/cloud spread | Reduces correlated slash risk |
| AVS Exposure | Which AVSs, caps per AVS, risk flags, slashing policy links | Defines your actual risk/return profile |
| Liquidity & Exit | AMM depth, withdrawal queue, cooldowns, secondary markets | Determines how quickly you can derisk during stress |
| Fees | Protocol fee, operator fee, performance fee | Directly reduces your net APY |
| Audits & Upgrades | Audit history, bug bounty, proxy patterns, emergency brakes | Controls blast radius of unexpected bugs |
Practical tip: Don’t chase every new LRT. Pick one or two with clear operator/AVS disclosures, then size positions so that a depeg or week-long exit doesn’t break your portfolio.
Operators & delegation: who actually does the work
Operators run the machines that fulfill AVS duties on your behalf. Think of them as specialized validators with broader responsibilities. When delegating, look for:
- Diversity: multiple cloud/region/client stacks; physical hardware where appropriate; documented disaster recovery.
- Monitoring: 24/7 alerting, open-source dashboards, on-call rotations.
- Scope: list of AVSs they run; whether they cap exposure per AVS; public incident reports.
- Fees & governance: transparent fee schedule; clear policy on upgrades, keys, and emergency procedures.
Delegation is reversible, but most protocols impose cooldowns to prevent mercenary capital from destabilizing AVSs. Expect unbonding periods during which you’re still at risk but not earning full rewards, plan your liquidity around that.
Step-by-step: restake safely as a non-validator
Compare frameworks: EigenLayer vs. alt-restaking
EigenLayer isn’t the only attempt to reuse crypto security. Newer frameworks explore modular or multi-asset restaking, sometimes on different chains. This table gives you a neutral way to compare, fill in concrete names as you research and decide.
| Dimension | EigenLayer (ETH) | Alt Restaking (Example) |
|---|---|---|
| Collateral | ETH / LSTs; inherits Ethereum security | May accept multiple assets; check quality of base security |
| AVS Scope | DA, oracles, sequencing, coprocessors, etc. | Varies; ensure slashing is enforceable |
| Slashing | Policy-driven; penalties can hit underlying restake | Check on-chain enforcement; beware “soft slashing” only |
| Operator Market | Competitive; public delegation marketplace | Some are permissioned or centralized |
| Fees/Incentives | Mix of fees + incentives; varies per AVS | Often emissions-heavy early on |
Use case framing: if you want highest alignment with Ethereum security and the broadest AVS marketplace, EigenLayer is the canonical venue. If you pursue alt-restaking, confirm how and where enforcement occurs and what the ultimate collateral is.
Security & operations checklist (print this)
- Position sizing: cap restaking exposure as a % of total ETH holdings. Conservative range for non-pros: 5–25% depending on liquidity needs.
- Diversify vectors: split across two operators and avoid overexposure to a single AVS or LRT.
- Document policies: bookmark operator pages, AVS slashing docs, and governance forums; set calendar reminders to review monthly.
- Wallet hygiene: maintain a cold vault for long-term ETH; use a daily-driver wallet for restaking & DeFi with limited balances.
- Alerting: enable notifications from operators/protocols; monitor withdrawal queues and LRT price deviations against NAV.
- Exit drills: practice a partial unwind during a calm window to understand fees/queues.
Frequently Asked Questions
Is restaking the same as “double staking”?
No. You don’t earn the base staking reward twice. You keep your base ETH staking APY and add whatever the AVSs pay (minus fees) for using your collateral as security. That extra yield exists because you’re taking on additional obligations and potential slashing.
Can I get slashed even if I use an LRT?
Yes. LRTs abstract complexity but cannot remove it. If an operator violates an AVS policy or if an AVS executes a valid slash, your LRT may bear loss according to the protocol’s rules. Read the “loss socialization” section of each LRT’s documentation.
What pays better: points, tokens, or fees?
Fees in ETH/stables are the most robust. Emissions and points can be attractive but are speculative. A blended approach can work, but don’t build your risk budget on assumptions that require a future airdrop to break even.
Do I need to run my own hardware?
Not for liquid restaking. If you run native validators, you’ll need enterprise-grade ops. For most users, delegation via reputable operators is the right starting point.
How big should my first position be?
Small enough that a 10–20% impairment (from depeg or a slash) doesn’t derail your portfolio. Start with a test deposit, observe accounting for a few reward cycles, then scale.
