From staking to liquid staking to restaking

To understand restaking, walk through three steps:

  1. Staking: you lock ETH to help secure Ethereum and earn rewards. The catch: your ETH is immobilized.
  2. Liquid staking: you deposit ETH into a protocol (Lido, Rocket Pool…) and receive a liquid token (stETH) representing your staked ETH that you can keep using in DeFi. It solves the lock-up.
  3. Restaking: you reuse that already-staked ETH (or the liquid staking token) to secure other services beyond Ethereum, and earn extra rewards for it. It's the next step, and the project that popularized it is EigenLayer.

What EigenLayer and AVS are

EigenLayer is a protocol on Ethereum that enables restaking. The idea: Ethereum has enormous economic security (millions of ETH staked), but that security only protects Ethereum. EigenLayer lets stakers "rent out" that security to other services.

Those services are called AVS (Actively Validated Services): bridges, oracles, data-availability layers, sequencers… Any system that needs a set of validators with money at stake can borrow Ethereum's security instead of bootstrapping its own from scratch. In return, restakers earn extra rewards.

The key risk: cascading slashing

Restaking isn't free money. The central risk is cascading slashing:

  • When you restake, your ETH backs several AVS at once.
  • If one of those AVS slashes you for a fault, you lose part of the collateral.
  • Because the same ETH is committed in multiple places, a failure in one unreliable AVS can spread losses to stakers who only wanted to secure Ethereum.

Other risks: complexity (you choose which AVS to back, and not all are reliable), smart-contract risk, and the "promised yield" risk typical of hype narratives.

How to take part (sensibly)

  • You need ETH. Starting from scratch, you can get it on an exchange like Binance or Coinbase and then withdraw it to your wallet.
  • You can restake native ETH or liquid staking tokens (LSTs) via EigenLayer or operators that run the AVS for you.
  • Start small, understand which AVS you're backing, and don't chase the highest APR without looking at the risk.

Frequently asked questions

What is restaking in crypto?

It's reusing already-staked ETH to secure additional services (AVS) beyond Ethereum, earning extra rewards in exchange for taking on more slashing risk.

What is EigenLayer?

A protocol on Ethereum that enables restaking: it connects ETH stakers with services that need economic security (the AVS).

Is restaking safe?

It adds risks on top of normal staking: cascading slashing, smart contracts and unproven AVS. It's not free money; the extra reward is the premium for that risk.

Is restaking the same as liquid staking?

No. Liquid staking gives you a liquid token for your staked ETH. Restaking reuses that ETH/token to secure more services. They're often combined (liquid restaking).

How much can you earn from restaking?

It depends on the AVS and market timing. Much of the appeal in 2026 comes from points and expected airdrops, not a guaranteed yield.
