What is restaking in crypto? How it compares to liquid staking

Restaking is a way to put the same staked crypto to work twice. You stake ETH to help secure Ethereum, then pledge that stake again to secure other services for extra rewards. Liquid staking sits a layer below, keeping your stake tradable. More yield is the pitch. More ways to lose money is the cost.

What restaking means

Here is the mechanism. You lock ETH as a validator, earn the base reward, then opt that same stake into backing extra protocols. Those protocols pay you on top. In return, your stake can be penalized if you break their rules.

Think of staking as renting out one apartment. Restaking rents that same apartment to several tenants at once. The rent adds up. So does the chance that one tenant trashes the place.

EigenLayer made this idea popular. The protocol began taking deposits in 2023 and accepts both ETH staked directly and liquid staking tokens from services like Lido and Rocket Pool, according to The Block.

Staking, liquid staking and restaking compared

Staking, liquid staking and restaking form a ladder, where each rung adds a layer on top of the one below.

At the bottom sits plain staking. You lock tokens with a proof-of-stake network to help run it and earn a reward. The catch is that the locked tokens sit idle. You often wait days to unlock them.

Liquid staking fixes the idle problem. A service such as Lido holds your stake and hands back a receipt token, stETH, that you can trade or use elsewhere while it keeps earning. Handing your ETH to a staking service does mean giving up direct control, unlike holding it in a non-custodial wallet. Lido's stETH is the largest of these tokens, worth about $23.57 billion as of 16 October 2026, according to DefiLlama and Lido's own dashboard.

Restaking adds the final rung. It takes a stake, native or liquid, and pledges it again to secure extra services. Same capital, more jobs. Each extra job pays, and each one can slash your stake if something goes wrong.

How EigenLayer restaking works

EigenLayer is the Ethereum protocol that turned restaking into a market. It connects two groups. On one side are restakers, who want more yield from stake they already hold. On the other are new services that need security but do not want to build their own validator set from scratch.

Those services are called Actively Validated Services, or AVS. They can be oracle networks, data availability layers, or bridges. Instead of bootstrapping their own trust, they borrow it from EigenLayer's pool of restaked ETH. EigenDA, a data availability service, was the first AVS to go live, in April 2024. Six more followed that same month, among them AltLayer, Brevis, and Lagrange, according to The Block.

Why borrow at all? A new proof-of-stake network faces a cold-start problem. Its security comes from the value staked to defend it, and a young project has little. The Block frames EigenLayer as a shared security model, where projects tap a common pool of restaked ETH rather than grow their own defense from zero. It put the cost of overpowering Ethereum's staked value at more than $190 billion. Borrowed scale is the selling point.

The appeal for restakers is money. EigenLayer's total value locked climbed past $15 billion in May 2024, The Block reported. That rush cooled after. By 16 October 2026 the figure sat near $6.29 billion, DefiLlama data showed. That drop is a useful reminder. Yield stories move fast, and capital leaves as fast as it arrives.

What you can restake, and where the yield comes from

Two kinds of stake can enter EigenLayer. The first is native ETH, staked by running your own validator. The second is a liquid staking token you deposit without running anything yourself, such as Lido's stETH, Rocket Pool's rETH, or Coinbase's cbETH. The Block lists all three as accepted.

Rewards come from the services, not from thin air. An AVS needs security and will pay for it. Node operators run the extra software and collect those payments, and restakers who delegate to them share the proceeds, The Block reported. EigenLayer later launched its own token, EIGEN, with a supply of 1.67 billion at its 2024 debut.

Worth a pause here. That payment only exists if real services use the network and keep paying for it. Early returns were lifted by token incentives and airdrop hunting, not steady fees alone. When those fade, the yield can fade with them.

Liquid restaking tokens and the protocols behind them

Restaking has the same liquidity problem staking did. Once you restake, your capital is committed again. Liquid restaking tokens, or LRTs, answer that. You deposit ETH or a liquid staking token into a protocol like EtherFi, Renzo, or Kelp. It restakes the asset through EigenLayer and gives you a receipt token in return. That token tracks your restaked position and can be traded or swapped back to ETH, The Block reported.

So a single deposit can now sit three layers deep. Staked, then liquid staked, then restaked, with a tradable token at each step. Each layer adds reward. Each layer also adds a new thing that can break.

The risks you take on with restaking

Restaking stacks risk the same way it stacks yield. The clearest danger is slashing. When you restake, you agree to the penalty rules of every service you back. Break one, and part of your stake can be taken. Back five services, and you carry five sets of rules. If you are still weighing the basics, our guide to whether staking crypto is worth it covers the ground floor.

Then comes the stacking problem. Liquid restaking tokens let the same ETH back several things while staying tradable. If one service is exploited or its code has a bug, the loss can ripple through every token built on top of it.

There is also peg risk. A liquid staking or restaking token is meant to track the value of the ETH behind it. In calm markets it does. Under stress, that token can trade below its backing. Sell at that moment, and you lock in the gap.

Not everyone is sold. Vitalik Buterin, Ethereum's co-founder, warned about this early. In a blog post on 21 May 2023 titled "Don't overload Ethereum's consensus," he argued that stretching the chain's consensus to secure other things could bring "high systemic risks to the ecosystem and should be discouraged and resisted," as Cointelegraph reported.

One more honest gap. The penalty systems for many services are still young, and their record under real stress is short. No one can promise the extra rewards will beat the extra risk. That part is not knowable yet.

What to weigh before restaking

Restaking is not a single decision. It is a stack of them. Each layer you add, from the staking service to the restaking protocol to the services it secures, is a separate thing to understand.

A few things decide how much risk you carry. One is how many services your stake backs, because each adds its own penalty rules. Another is whether the protocol's code has been audited, and by whom. A third is how concentrated your choice is, since one popular token can mean many users share a single failure point.

None of this is advice to restake or to avoid it. It is the homework the extra yield asks for. Skip it, and you are trusting layers you cannot see.
