What Is Restaking? EigenLayer Explained
Restaking is a new innovation in the Ethereum ecosystem that allows users to reuse their staked ETH to secure multiple protocols simultaneously. This concept is pioneered by EigenLayer, a protocol designed to extend Ethereum’s security to other decentralized services.
In this guide, we’ll explain what restaking is, how EigenLayer works, its benefits, risks, and why it matters for the future of crypto and DeFi.
EigenLayer is a restaking protocol built on Ethereum that allows validators to extend Ethereum’s proof-of-stake security to additional decentralized services.

1. What Is Restaking?
Restaking is the process of using already staked ETH (or liquid staking tokens like stETH) to secure additional protocols beyond Ethereum’s base consensus layer.
Instead of staking ETH once for a single reward, restaking allows users to reuse Ethereum’s economic security to earn extra yield by validating other services.
2. What Is EigenLayer?
EigenLayer is a protocol built on Ethereum that enables restaking. It allows ETH stakers and node operators to opt in and provide security for third-party applications.
EigenLayer acts as a middleware layer that connects Ethereum’s validators to new decentralized services, while enforcing additional slashing conditions.
3. How Does Restaking Work?
- Users stake ETH or liquid staking tokens.
- They opt in to EigenLayer smart contracts.
- ETH is restaked to secure extra protocols.
- Users earn additional rewards.
- Misbehavior can result in slashing.
This system allows Ethereum’s trust and capital efficiency to be shared across the ecosystem.
4. Actively Validated Services (AVSs)
AVSs are protocols that rely on EigenLayer’s restaked ETH for security.
Examples include:
- Data availability layers
- Oracles
- Cross-chain bridges
- Rollup infrastructure
AVSs benefit from Ethereum-level security without building a validator set from scratch.
5. Benefits of Restaking
- Higher Yield: Earn rewards from multiple protocols
- Capital Efficiency: One stake, many uses
- Shared Security: Stronger protection for new protocols
- Ethereum Ecosystem Growth: Faster innovation
6. Risks and Challenges of Restaking
Despite its benefits, restaking carries risks:
- Additional slashing conditions
- Smart contract vulnerabilities
- Increased system complexity
- Centralization risks
Users should fully understand the risks before opting in.
7. Restaking vs Traditional Staking
| Feature | Staking | Restaking |
|---|---|---|
| Security Scope | Ethereum only | Multiple protocols |
| Rewards | Single yield | Multiple yields |
| Risk Level | Lower | Higher |
8. Who Should Consider Restaking?
Restaking is suitable for:
- Experienced Ethereum stakers
- Liquid staking token holders
- Node operators seeking higher returns
Beginners should start with traditional staking before exploring restaking.
To learn more about Ethereum staking fundamentals, you can refer to the official Ethereum documentation .
9. The Future of Restaking
Restaking could become a foundational layer for Web3 infrastructure.
As EigenLayer matures, more AVSs will rely on shared security, potentially making Ethereum the security backbone of the entire crypto ecosystem.
10. Conclusion
Restaking via EigenLayer introduces a powerful new way to maximize ETH utility and rewards. While it unlocks higher yield and shared security, it also increases risk.
Understanding how restaking works is essential before participating. As always, do your own research and assess your risk tolerance.

Restaking is often combined with liquid staking tokens such as stETH, making capital more efficient.
If you’re new to Ethereum, it’s recommended to understand what staking is before exploring restaking.
