Restaking is a primitive that allows you to use your already-staked ETH to provide security for other decentralized services (AVSs) at the same time. This lets investors earn additional rewards on top of their standard staking yield.
Restaking, pioneered by the EigenLayer protocol, is one of the most significant innovations in DeFi since the launch of Ethereum's Proof of Stake. Normally, when you stake ETH, your assets are "locked" to secure the Ethereum network. In exchange, you earn a percentage of the network's fees and new issuance. Restaking takes this a step further: it allows that same staked ETH to be "opted-in" to secure other things, such as bridges, data availability layers, or oracles. These third-party services are called Actively Validated Services (AVSs).
The logic is simple: Ethereum has a massive amount of "economic security" (billions of dollars in staked ETH). Other new protocols struggle to attract enough capital to be secure. By "restaking," Ethereum stakers can lend their security to these new protocols. If the staker (or their chosen operator) misbehaves on the new protocol, their staked ETH can be "slashed" (taken away), just like it would be on Ethereum. This creates a "shared security" model where the entire ecosystem can benefit from Ethereum's massive trust base.
For investors, restaking is a "yield play." You earn your base ETH staking yield (~3-4%), plus additional rewards from the AVSs you choose to support. However, this comes with "leveraged risk." If there is a bug in the AVS code or a mistake by your operator, you could lose your ETH even if you did nothing wrong on the Ethereum mainnet. It also creates a concern about "consensus overload," where too many things depending on Ethereum's security could create systemic risks if a major failure occurs. Understanding the balance between "extra yield" and "extra slashing risk" is the key to being a successful restaker.
Frequently Asked Questions
Can I restake any token?
Currently, restaking is primarily focused on ETH and Liquid Staking Tokens (like stETH), though some protocols are exploring restaking for other assets.
Do I have to run a node to restake?
No. Most users "delegate" their restaked ETH to an "Operator" who handles the technical work of securing the AVSs for a small fee.
Is restaking the same as liquid staking?
No. Liquid staking gives you a token (like stETH) representing your stake. Restaking uses that stake to secure *additional* networks for *additional* yield.

Staking
Staking is locking up cryptocurrency to help secure a proof-of-stake blockchain network in exchange for rewards — typically 3-15% APY depending on the network. It is a lower-risk alternative to yield farming and a popular passive income strategy for long-term holders.
Liquid Restaking Tokens (LRTs)
Liquid Restaking Tokens (LRTs) are tokens that represent a user's restaked ETH and its associated rewards. They allow investors to keep their capital "liquid" so it can be used in other DeFi apps while it is simultaneously earning restaking yield.
Actively Validated Services (AVSs)
An AVS is any decentralized service that requires its own set of validators for security but chooses to "borrow" that security from Ethereum stakers via restaking. Examples include oracles, bridges, and data availability layers.
