If you have looked at a swap screen on Base and seen tokens like weETH or ezETH sitting next to more familiar names like cbETH or wstETH, you have run into restaking. It looks similar to regular liquid staking at first glance, a token that represents ETH earning yield somewhere else, but the mechanism underneath is different, and so is the risk. This guide covers what restaking actually is, what a liquid restaking token represents, and what to check before you hold one.
A quick refresher on staking
Ethereum runs on proof of stake. Validators lock up ETH and use it to propose and confirm blocks, earning rewards for doing that correctly. Our guide to liquid staking tokens covers how tokens like cbETH and wstETH let you hold a claim on staked ETH and its rewards without running a validator yourself. That is the baseline restaking builds on top of.
What restaking adds
Restaking takes ETH that is already staked, or a liquid staking token that represents it, and uses that same economic backing to secure other services, not just the Ethereum base layer. The idea was popularized by a protocol called EigenLayer, which lets stakers opt in to back things like data availability layers, oracle networks, and other infrastructure that would otherwise need to bootstrap their own independent set of validators and their own economic security from scratch.
In practice, restaking works through a few roles:
- Restakers deposit ETH or a liquid staking token and opt in to back one or more services.
- Operators run the actual infrastructure (nodes, software) required by those services.
- The services being secured, sometimes called actively validated services, define what work needs doing and what counts as misbehavior.
In exchange for taking on this extra duty, restakers can earn additional rewards on top of ordinary staking yield. In exchange for that extra yield, they also accept extra ways their stake can be penalized if the operator they delegate to misbehaves or a service they are backing gets slashed.
What a liquid restaking token represents
Running a validator and manually restaking it across several services is not practical for most individual holders. Liquid restaking protocols solve this the same way liquid staking protocols did: you deposit ETH or an eligible staking token, the protocol pools it, restakes it across a set of services on your behalf, and issues you a single token representing your share.
Two examples that show up on Base:
weETH (Wrapped eETH), from ether.fi. You can look up its Base contract on BaseScan. It represents a claim on ETH that has been staked and restaked through ether.fi's protocol, wrapped into a non-rebasing token designed for use in DeFi and on other networks including Base.
ezETH (Renzo Restaked ETH), from Renzo. Its Base contract is also verifiable on BaseScan. Renzo acts as a strategy manager that deposits ETH into EigenLayer on a holder's behalf and issues ezETH as the receipt token.
In both cases, the token's exchange rate against ETH is meant to rise over time as staking and restaking rewards accrue, similar to how cbETH or wstETH behave. The difference is what backs that yield. A plain liquid staking token's value depends on Ethereum validator rewards and slashing risk alone. A liquid restaking token's value depends on that, plus the performance and slashing conditions of every additional service the underlying position has been restaked into.
The extra risk, stated plainly
Restaking is often described as earning extra yield "for free" because it reuses capital that is already staked instead of requiring a fresh deposit. That framing understates what is actually happening. Each additional service a restaked position backs is a new smart contract, a new operator, and a new set of slashing conditions layered on top of the original staking risk. A bug or a malicious operator in any one of those layers can affect the restaked position, even if Ethereum's own consensus layer works exactly as intended.
A few things worth checking before holding a liquid restaking token, beyond what you would check for a plain liquid staking token:
Which services is it restaked into. A restaking protocol that spreads deposits across many operators and services concentrates risk differently than one that commits everything to a single, newer service. This is disclosed on the protocol's own dashboard, not something a wallet can determine on your behalf.
How new is the service being secured. A service that has been running and audited for a long time carries different risk than one that just launched. Time in production is not a guarantee, but a track record is still worth more than a promise.
What slashing actually covers. Some restaking systems slash for provable, objective faults like double signing. Others rely on more subjective fault definitions that carry their own disagreement risk. The specific conditions vary by protocol and by which services are opted into.
Whether yield is paid in more of the same token, in a separate reward token, or in points that convert to a token later. Points based reward programs in particular add a layer of uncertainty about what the eventual reward is actually worth, since it does not exist as a tradeable asset yet.
Restaking is not a shortcut around staking risk
It is tempting to read a higher advertised yield as simply "more of a good thing." Restaking is closer to underwriting several separate obligations with the same collateral. That can be a reasonable tradeoff for holders who understand what they are opting into, but it is not the same risk profile as holding ETH directly or holding a plain liquid staking token, and it should not be evaluated as if it were.
The short version
Restaking lets already staked ETH secure additional services beyond Ethereum itself, and a liquid restaking token like weETH or ezETH is a single tradeable claim on that restaked position and its rewards. It builds directly on top of ordinary staking, but it stacks additional smart contract, operator, and slashing risk on top rather than replacing the original risk with something safer. Treat a liquid restaking token's yield as compensation for a more layered risk, not as a strictly better version of a liquid staking token.
