The crypto industry was shaken to its core in early April 2026. Kelp DAO, a leader in liquid restaking, fell victim to an advanced exploit. The attack resulted in the theft of approximately $292 million worth of assets and is believed to be associated with the North Korea-based Lazarus Group. They didn’t just break code but manipulated verifier systems, the basic infrastructure that retsaking protocols rely on to function across different blockchains.
But if it is so risky, why do so many people pour billions into backing this technology? And before we get into staking, let’s give you a little recap of what staking is. On proof-of-stake (PoS) blockchains like Ethereum, you lock up your crypto (say, ETH) to help validate transactions and keep the network secure. In return, you get rewards, usually a few percent APY. It’s like putting money in a savings account, but you’re helping the blockchain run instead of a bank.
What is Restaking?
Restaking takes this same idea and takes it up a notch. It is the act of taking tokens you have already “staked” on a primary network (like Ethereum) and further using them to secure additional applications or networks at the same time. Simply put, your already staked ETH helps you secure Ethereum, and when you restake it, it helps you secure other decentralized services or networks simultaneously. Basically, it’s about using the same capital to perform multiple jobs and thus obtain more rewards on top of your original staking yield. It’s a way to get more out of your assets and increase capital efficiency.
The early entrant in this space is EigenLayer, which launched this concept on Ethereum. They showed how, instead of letting your staked ETH just sit there protecting Ethereum, it could be used to back things like data availability layers for rollups, oracles that feed real-world data on-chain, or even new sidechains and bridges. These extra services are called Actively Validated Services (AVSs). Think of it as your stake becoming shared security for a whole ecosystem of apps and chains.

To help us better understand this concept, let’s try to put it in an analogy. Imagine that you buy a super-advanced security system for your house. You’ve already paid for the cameras and the monitoring service. Restaking is like telling your neighbor, “Hey, my cameras can see your front door, too. If you pay me a small monthly fee, I’ll monitor your property using the equipment I already have.
Here, your “house” is the Ethereum mainnet, and your “neighbor” is a new protocol. This could be anything from a decentralized oracle or a new bridge. They would need security because they are new and don’t have their own massive army of validators yet.
What Do You Need to Get Started?
Entering the world of restaking isn’t as simple as clicking a button, but it’s becoming more user-friendly. Generally, you need one of two things:
Native restaking: You run your own Ethereum validator node (requires at least 32 ETH and some technical setup). You point your validator’s withdrawal credentials to the restaking protocol so it can use your stake for AVSs too.
Liquid restaking: This concept is much easier for most people. You stake ETH through a liquid staking provider (like Lido for stETH), then deposit that liquid staking token (LST) into a restaking platform. In return, you get a liquid restaking token (LRT) like rsETH from Kelp or eETH from ether.fi. This LRT keeps earning the combined rewards, but you can still trade it, use it as collateral in DeFi, or lend it out.
How Does Restaking Actually Work?
Here’s the flow in simple terms:
- You have staked ETH (either native or via an LST).
- You deposit it (or the LST) into a restaking protocol’s smart contracts.
- The protocol delegates your stake to operators—trusted node runners who actually run the software for the AVSs.
- Those operators use your stake’s “attestation power” to validate and secure the extra services.
- In return, the AVSs pay fees or incentives which then flow back to you as extra rewards on top of the base staking yield of Ethereum. Total APY can sometimes hit 8-15% or more, depending on the AVSs and market conditions (though it fluctuates).
Slashing still applies. If an operator messes up on Ethereum, you lose part of your stake as usual. If they mess up on an AVS (say, by signing bad data), you can face extra slashing specific to that service. That’s why choosing reputable operators and not over-concentrating matters.
The Pros of Getting into Restaking
Most people are attracted to it because it offers higher yields. You can earn extra rewards on top of the ~3-4% yield of Ethereum staking from multiple AVSs and stack them up on top of each other to potentially increase your total returns significantly. You are making your money work twice (or thrice) as hard. You don’t need to buy new tokens to support a new project; you use what you already have.
More importantly, restaking makes it much cheaper and faster for new blockchain projects to launch. They don’t have to spend years building a multi-billion dollar security pool; they can just “rent” security from Ethereum’s existing pool.
The Cons to Watch Out For
As the Kelp DAO hack proved, restaking isn’t a “free lunch.” It introduces several layers of risk:
If the secondary service you are securing has a technical glitch or a malicious operator, you could lose your ETH, even if you did everything right on the Ethereum mainnet. Often, you’re placing your faith in a “Node Operator” on the technical side. If they go offline or get hacked, your funds are at risk. And restaking can have a domino effect. If a major restaking token like rsETH drops in value, or gets hacked, it could have a chain reaction throughout the entire DeFi ecosystem, impacting lending platforms and liquidity pools. Critics have said that when everyone uses the same restaking platform, it creates a “single point of failure” – the very thing that the Kelp DAO hackers exploited.
Who Are the Key Players?
If you’re looking to explore this space, here are some of the firms currently leading the charge:
EigenLayer: They are considered the “Grandfather” of restaking. Its the foundational marketplace where you can delegate ETH to various AVSs.
Kelp DAO: This is for Liquid Restaking (LRTs). They mint rsETH which allows users to stay liquid and earn restaking points and yields.
Ether.fi: Native liquid restaking protocol. They allow users to keep control of their keys while restaking, offering the eETH token.
Renzo: This is a strategy manager for the EigenLayer. It automates the process of choosing which AVSs to secure to maximize yield.
Besides the Ethereum Network, there are restaking protocols on Solana ecosystem as well. One siuch protocol is Jito. They bring the restaking model to Solana to secure “NCNs” (Network Canary Networks).
What you need to know before restaking?
If a platform is offering 50% yield while others offer 10%, there is a massive hidden risk. High yield usually means higher slashing risk or unverified code. Secondly, don’t put all your ETH into one liquid restaking token. Spread it across a few established players like Ether.fi, Renzo, or Puffer. Also remember many restaking protocols have a “cooling off” period. You might not be able to get your ETH back instantly; it could take days or even weeks.
Pro Tip: Don’t forget to ask, “Does this protocol use a decentralized verifier network?” Avoid any project that relies on a single point of failure.
The Way Forward
Restaking is a double-edged sword. It is perhaps the most significant innovation in capital efficiency since the invention of the automated market maker (AMM). However, it also adds a layer of systemic risk that we are still learning to manage. The recent exploit is a stark reminder that innovation without rigorous security is expensive. As a user, your goal isn’t to avoid risk entirely, but to ensure you’re being paid fairly for the specific risks you’re taking.
