What is Restaking?
Restaking is the practice of using your already-staked Ethereum or other staked assets to simultaneously secure additional networks or services. Instead of your staked ETH only earning rewards from Ethereum validators, it can earn rewards from multiple different networks at the same time.
Think of it like renting out your security. Your staked Ethereum provides security guarantees to Ethereum. With restaking, you lend those same security guarantees to other networks and services through a smart contract, earning additional yield without needing to stake more capital.
Key Benefit: Restaking unlocks additional revenue streams on capital that's already deployed, significantly increasing yield for Ethereum stakers.
Traditional Staking vs Restaking
Traditional Staking
- β’ Stake ETH on Ethereum
- β’ Earn ~3-4% APY
- β’ Secure only Ethereum
- β’ Slashing risk only from Ethereum
Restaking (EigenLayer)
- β’ Deposit staked ETH in EigenLayer
- β’ Earn 3-4% base + additional AVS yields
- β’ Secure Ethereum + multiple AVS
- β’ Slashing risk from participating networks
How EigenLayer Works
EigenLayer is a smart contract protocol that enables liquid restaking on Ethereum. It's the primary infrastructure enabling restaking at scale.
EigenLayer Architecture
- 1.Stake ETH: Deposit staked ETH (via LSTs or solo validators) into EigenLayer contracts
- 2.Receive restaking token: Get a liquid restaking token (LRT) representing your deposit
- 3.Opt into AVS: Choose which Actively Validated Services to secure
- 4.Earn rewards: Collect staking rewards from Ethereum + AVS rewards
- 5.Risk slashing: Accept potential slashing if validators behave maliciously
Key Features
- βModular Security: Security is decoupled from tokens, can be applied to any network
- βOpt-in AVS: Choose which services to secure; fine-grained control
- βLiquid Restaking: LRTs are liquid and can be traded, unlike traditional staking
- βPrimitive Layer: Designed to be the base layer for restaking infrastructure
Important: EigenLayer is still in early stages. The protocol has been audited, but restaking represents higher risk than traditional staking due to slashing exposure.
Actively Validated Services (AVS)
AVS are networks or services that use EigenLayer to source their security. They pay operators (validators) to secure them, and those operators use restaked ETH as collateral.
Types of AVS
Rollups & Side Chains
Layer 2 scaling solutions that rent EigenLayer security instead of running own validator set.
Data Availability Services
Services that commit to data availability (like EigenDA), secured by restakers.
Execution Environments
Custom execution layers that need security guarantees.
Oracle Networks
Price feeds and other oracle services secured by staked collateral.
Earning from AVS
When you opt into an AVS, you earn rewards from multiple sources:
- β’Base Staking Rewards: Ethereum validator rewards (continue earning)
- β’AVS Rewards: Direct payments from AVS operators
- β’AVS Tokens: Many AVS launch their own tokens for governance and incentives
Popular AVS Examples
- β’ Eigenda - EigenLayer's data availability solution
- β’ Mantle - L2 rollup using EigenLayer security
- β’ Various oracle and middleware services
- β’ More launching as ecosystem develops
Liquid Restaking Tokens
Liquid Restaking Tokens (LRTs) are derivative tokens that represent your stake in an EigenLayer restaking protocol. They allow your restaked capital to remain liquid and tradeable.
Major Liquid Restaking Tokens
ezETH (EigenLayer)
Token from the EigenLayer foundation, representing restaked Ethereum. Has native integration with EigenLayer.
Initial yields: 8-12%+ depending on AVS participation
rsETH (Kelp DAO)
Community-driven liquid restaking token, aggregates multiple operators and AVS strategies.
Multi-asset support with diverse yield strategies
pufETH (Puffer Finance)
Permissionless liquid restaking focused on decentralization and small validators.
Emphasizes censorship resistance
Others: weETH, mETH, etc.
Various protocols launching LRT solutions with different strategies.
New entrants continuously emerging
LRT Advantages
- βLiquidity: Trade your restaked position without unstaking
- βComposability: Use LRTs as collateral in DeFi protocols
- βStrategy Management: Let experts manage AVS selection and rewards
- βLower Entry: Access restaking with smaller amounts
Risks of Restaking
While restaking offers higher yields, it introduces new risks that traditional staking doesn't have. Understanding these is critical before deploying capital.
Slashing Risk (Most Important)
If validators misbehave or are compromised, some of your staked ETH may be slashed. The extent of slashing varies by AVS and type of misbehavior.
Multiple AVS means multiple slashing conditions you're exposed to. Careful AVS selection is critical.
Operator Risk
You're trusting operators (validators) to not behave maliciously. Compromised or negligent operators can cause slashing losses.
Smart Contract Risk
EigenLayer contracts hold billions in value. Bugs or exploits could result in total loss, though audits have been performed.
Liquidity Risk
LRT tokens may trade at a discount to their underlying value if there's low liquidity or high redemption pressure.
Correlated Failure Risk
Multiple AVS may face the same underlying cause (network upgrade, layer 1 issue), causing correlated slashing across all.
Unlock/Exit Risk
If an AVS faces issues, you may face lock-in periods before exiting, unable to sell even if price crashes.
Yield Optimization Strategies
Conservative Strategy
Opt into only the most established, battle-tested AVS (like EigenDA). Accept lower yields for reduced risk.
Expected yield: 5-7% APY
Diversified Strategy
Spread stake across multiple AVS from reputable teams. Balances yield opportunities with risk diversification.
Expected yield: 10-15% APY
Aggressive Strategy
Opt into many new, higher-yielding AVS. Accept significant slashing risk for maximum returns.
Expected yield: 20%+ APY (but with substantial risk)
DeFi Composability Strategy
Use LRTs as collateral in lending protocols (Aave, Compound) while earning restaking yields. Compound returns.
Expected yield: 15-25% APY plus additional leverage
Best Practice: Start small, understand your risk tolerance, monitor slashing events, and adjust your AVS portfolio periodically.
Future of the Restaking Ecosystem
Growing AVS Ecosystem
More L2s, data services, and infrastructure projects will emerge needing security. This expands yield opportunities but also complexity.
Multi-Asset Restaking
EigenLayer is exploring restaking with other assets beyond ETH (liquid staking tokens, other cryptocurrencies), increasing capital efficiency.
Operator Markets
Specialized companies will emerge as operators, managing staker capital and AVS selection, similar to stake pools.
Risk Markets
Insurance protocols and slashing derivatives will emerge to manage and hedge slashing risk, making restaking safer.
Standardization
As the ecosystem matures, standards will emerge for AVS quality assessment, operator reputation, and slashing prevention.
Vision: Restaking could become the standard way Ethereum security is monetized, creating a robust market for consensus security services.
Key Takeaways
1. Restaking lets you earn additional yield on staked ETH by securing multiple networks simultaneously through EigenLayer.
2. Liquid restaking tokens (ezETH, rsETH, pufETH) make restaking accessible and liquid without sacrificing staking rewards.
3. Slashing risk is the primary concern with restaking; participating in multiple AVS increases your exposure to different failure modes.
4. Higher yields require taking more risk; balance your restaking portfolio based on your risk tolerance and understanding of protocols.
