Restaking and EigenLayer Explained: An Australian Investor's Primer

Restaking has been one of the most-discussed DeFi primitives of the last two years, and EigenLayer is the protocol that introduced the concept at scale. The basic idea is that staked ETH can be ‘restaked’ to provide security to additional protocols beyond the Ethereum base chain — earning additional yield in exchange for additional slashing risk. For Australian DeFi investors, the question is whether restaking is the genuine new yield primitive that proponents argue, or a more complicated form of leverage with risks that have not yet been stress-tested. This guide explains what restaking is, how EigenLayer works, the AVS (Actively Validated Service) concept, the Australian tax treatment, and where restaking fits in a DeFi portfolio.

What restaking is

Restaking is the practice of taking ETH that is already staked on Ethereum and using the same stake to also provide security to other protocols — protocols that need a large pool of economic security but do not want to bootstrap their own validator set. The restaked ETH earns the base Ethereum staking yield plus additional yield from whichever other protocols (AVSs, in EigenLayer’s terminology) it is securing.

The trade-off is that the restaked ETH is now subject to slashing conditions from the additional protocols, not just from Ethereum itself. If an AVS the ETH is securing slashes its validators for misbehaviour, the restaked ETH bears part of the loss.

How EigenLayer works

EigenLayer is the protocol that introduced restaking. A holder of staked ETH (whether directly staked or held as an LST like stETH or rETH) deposits into EigenLayer. The deposit becomes available to be ‘opted in’ to various AVSs. The depositor (or the operator they delegate to) chooses which AVSs to participate in, which determines which slashing risks are accepted and which yields are earned.

AVSs are a wide category. Examples include data availability layers (EigenDA), oracle networks, cross-chain bridges, decentralised sequencer networks for Layer 2s, and various other infrastructure services that need economic security. Each AVS pays node operators (and through them, restakers) in its own token or in ETH.

Liquid restaking tokens (LRTs)

Liquid restaking tokens are the next layer of abstraction. Protocols like ether.fi, Renzo, Kelp and Puffer let users deposit ETH (or stETH) and receive a liquid restaking token (eETH, ezETH, rsETH, pufETH respectively). The LRT represents the user’s claim on the restaked underlying plus the AVS rewards, while remaining tradable across DeFi.

LRTs are popular because they let retail users access EigenLayer yields without making the complex AVS-selection and operator-delegation decisions themselves. The LRT protocol makes those decisions on behalf of the deposit pool.

The risks specific to restaking

Three additional risk categories that direct ETH staking does not have. First, AVS slashing — if the AVSs your restaked ETH is securing slash their participants for misbehaviour, you lose ETH. Different AVSs have different slashing conditions, and not all have been stress-tested. Second, operator risk — most retail restakers delegate to a node operator who selects AVSs and runs the infrastructure; if the operator is incompetent or malicious, the restaker bears the loss. Third, smart-contract risk — EigenLayer and the LRT protocols on top are complex multi-layered systems with substantial smart-contract surface.

Restaking yields have to compensate for these additional risks. As of 2026, total restaking yields (Ethereum base + AVS rewards) have generally been in the 5–10% range, varying with AVS selection and market conditions. Compared to base Ethereum staking yield of around 3%, the marginal yield is 2–7 percentage points for the additional risk taken.

The depeg risk for LRTs

LRTs have had depeg incidents. In early 2024, several LRTs traded at multi-percent discounts to their underlying for extended periods due to liquidity imbalances and uncertainty about AVS rewards. The same depeg dynamic that affects LSTs is amplified for LRTs because the additional layers of complexity reduce the willingness of arbitrageurs to maintain a tight peg.

Australian tax treatment of restaking

Restaking adds layers to the LST tax treatment. The wrap from ETH or stETH into an LRT is a CGT event. The ongoing yield from AVS rewards is ordinary income at the AUD value on the day received. AVS rewards paid in non-ETH tokens add another layer of complexity because each reward token has to be tracked from receipt to disposal. Slashing events would be capital losses.

This is one of the messiest reconciliation cases in Australian crypto tax. CryptoTaxCalculator handles the main EigenLayer and LRT cases but manual review is generally needed. For Australians thinking about restaking, the operational complexity of getting the tax reconciliation right is itself a meaningful overhead.

Where restaking fits

Restaking is appropriate for Australian DeFi users who specifically want to be paid for taking AVS slashing risk in exchange for additional yield over base ETH staking. It is not appropriate as a beginner’s first DeFi position. The complexity-to-yield ratio is worse than direct staking, and the additional risk categories add up. For most Australian crypto investors, base ETH staking through a credible LST (Lido or Rocket Pool) is sufficient — restaking adds 2–7 percentage points of yield for materially more risk and operational overhead.

For more sophisticated users with a real view on which AVSs are valuable and which are not, EigenLayer provides a way to express that view. The category is still early and the long-tail risk has not yet been stress-tested. The 2022 LST stress test showed how LST pegs behave under pressure; restaking has not yet faced an equivalent stress event.

Verdict

Restaking and EigenLayer are real DeFi primitives that are unlikely to disappear, but the risk-reward for Australian retail investors is less attractive than the headline marketing suggests. The additional 2–7 percentage points of yield over base ETH staking comes with multiple new risk categories, additional smart-contract layers, and meaningfully more complex Australian tax reconciliation. For Australians with serious DeFi sophistication, restaking is a credible position — though sizing should reflect the additional risk. For most retail Australian crypto investors, base ETH staking via Lido or Rocket Pool remains the better risk-adjusted yield.

Frequently asked questions

What is restaking?

Using already-staked ETH to also provide security to additional protocols (AVSs) beyond Ethereum itself, earning additional yield in exchange for additional slashing risk.

What is EigenLayer?

The protocol that introduced restaking at scale. Holders of staked ETH or LSTs deposit into EigenLayer and opt in to securing various AVSs (data availability layers, oracle networks, bridges and other infrastructure services).

What are LRTs?

Liquid restaking tokens — tokens issued by protocols like ether.fi, Renzo, Kelp and Puffer that represent restaked underlying plus AVS rewards while remaining tradable. They let retail users access restaking yields without making AVS-selection decisions.

How risky is restaking?

More risky than direct staking. The additional risks are AVS slashing, operator risk, and additional smart-contract risk from multiple protocol layers. Yields have to compensate, and have generally been 2–7 percentage points above base ETH staking.

How is restaking taxed in Australia?

Wraps into LRTs are CGT events. AVS rewards are ordinary income on receipt at the AUD value. Slashing events are capital losses. CryptoTaxCalculator handles the main cases but manual review is generally required.
