Ethereum staking has become one of the most popular ways for investors to earn passive rewards, but a new innovation called restaking is taking that concept a step further. Instead of using staked ETH solely to secure the Ethereum network, restaking allows the same assets to help protect additional blockchain services while generating extra rewards.
At the center of this growing ecosystem is EigenLayer, a protocol that has transformed Ethereum’s security into a shared resource for decentralized applications. While the opportunity for higher yields has attracted billions of dollars in deposits, restaking also introduces new risks that investors should fully understand before participating.
How Ethereum staking works
To understand restaking, it’s important to first understand traditional Ethereum staking.
Ethereum validators lock 32 ETH into the network to help validate transactions and secure the blockchain. In return, they receive staking rewards. However, if validators act maliciously or fail to meet network requirements, part of their stake can be slashed, meaning a portion of their ETH is permanently lost.
Liquid staking protocols such as Lido and Rocket Pool made staking more flexible by allowing users to receive liquid tokens like stETH or rETH, which can still be used across decentralized finance (DeFi) while the original ETH remains staked.
What is restaking?
Restaking builds on this idea by allowing already-staked ETH to secure other blockchain services beyond Ethereum.
Instead of creating separate validator networks and token economies, new blockchain projects can borrow Ethereum’s security through restaking. This means the same ETH can protect multiple protocols at once while earning additional rewards for investors.
EigenLayer introduced this model on Ethereum in 2023 and has since become the largest restaking protocol, attracting billions of dollars in total value locked.
How EigenLayer works
EigenLayer connects three main participants:
- Restakers who deposit staked ETH or liquid staking tokens.
- Operators who run validator software for external services.
- Actively Validated Services (AVSs) that use Ethereum’s economic security instead of building their own validator networks.
Here’s how the process works:
- Users deposit ETH or liquid staking tokens into EigenLayer.
- Those assets are delegated to an operator.
- Operators secure one or more AVSs.
- Restakers continue earning Ethereum staking rewards while also receiving additional incentives from the AVSs they support.
This shared-security model helps new blockchain projects launch without requiring billions of dollars in their own staking capital.
What are Actively Validated Services?
Actively Validated Services (AVSs) are blockchain applications that use EigenLayer’s shared security.
These services include:
- Data availability layers
- Oracle networks
- Cross-chain bridges
- Keeper networks
- Off-chain computation services
Instead of relying on separate staking systems, AVSs leverage Ethereum’s existing validator network, reducing costs while benefiting from stronger economic security.
Liquid restaking adds another layer
As liquid staking created tradable staking tokens, liquid restaking introduces tokens that represent restaked positions.
Leading liquid restaking protocols include:
- Ether.fi (eETH)
- Renzo (ezETH)
- Puffer (pufETH)
- Kelp (rsETH)
These tokens allow investors to continue using their restaked assets across DeFi while still earning multiple reward streams.
However, every additional layer also increases exposure to smart contract risks and potential liquidity issues.
Why investors are interested
Restaking has become popular because it increases the earning potential of already-staked ETH.
Instead of receiving only Ethereum staking rewards, investors may also earn:
- Ethereum staking rewards
- Liquid staking rewards
- AVS incentives
Combined yields can become significantly higher than traditional staking alone, making restaking an attractive option for many long-term ETH holders.
The biggest risks of restaking
Higher rewards also come with greater risk.
Unlike standard staking, restaked ETH can be exposed to multiple forms of slashing.
Potential risks include:
- Ethereum consensus slashing
- AVS-specific slashing rules
- Smart contract vulnerabilities
- Correlated failures across multiple protocols
- Liquid restaking token depegging
- System-wide liquidation risks during market stress
Because each AVS sets its own slashing conditions, investors must carefully understand where their assets are being delegated before participating.
Competition is growing
Although EigenLayer remains the market leader, several competing restaking platforms are entering the space.
These include:
- Symbiotic
- Karak
- Babylon, which extends the restaking concept to Bitcoin.
The emergence of multiple platforms suggests that shared blockchain security could become one of the most important sectors within decentralized finance over the coming years.
Choosing the right operator matters
Not every operator carries the same level of risk.
Professional operators generally maintain stronger infrastructure, better security practices, and more conservative participation across AVSs.
Before restaking, investors should review:
- Operator uptime
- Security history
- Supported AVSs
- Slashing history
- Infrastructure reliability
Regularly monitoring delegated positions is also important, as operators can change the services they support over time.
Final thoughts
Restaking is reshaping how blockchain security works by allowing Ethereum’s validator network to secure multiple decentralized services simultaneously. EigenLayer has pioneered this model, creating new income opportunities for ETH holders while helping emerging protocols launch with stronger security.
However, higher rewards come with additional complexity and multiple layers of risk. Investors considering restaking should carefully evaluate operators, AVSs, and liquid restaking platforms before committing capital.
As competition expands and new shared-security networks emerge, restaking could become a key building block of the next generation of decentralized finance—but understanding the risks is just as important as chasing the rewards.
