Liquid Staking and Restaking: Where the Extra Yield Comes From and What Can Go Wrong

Proof of stake yield has exactly two native sources: new coin issuance and a share of transaction fees. Everything above that baseline has to come from somewhere else. In liquid staking and restaking, the extra yield is assembled from four ingredients: payments from services that rent your staked collateral as security, token emissions from protocols buying growth, points programs that pay in airdrop speculation rather than cash, and borrowed positions that multiply all of the above. None of these are free money. Each one is compensation for a specific risk, and the risks stack on top of each other rather than replacing one another. Keep that framing: when advertised yield goes from 3 percent to 12, the risk did not quadruple in one place, it multiplied across several.

Normal staking locks your ETH with a validator. Liquid staking protocols like Lido take your ETH, stake it across their node operator set, and hand you a receipt token, stETH, that you can trade, spend, or use in DeFi while the underlying ETH keeps earning. stETH rebases daily, meaning your balance ticks up as rewards accrue, and Lido keeps 10 percent of the rewards as its fee, split between node operators and the DAO treasury. For DeFi use there is wstETH, a wrapped version whose balance stays fixed while its exchange rate rises.

The receipt is the key concept and the key risk. stETH is a claim on ETH held by someone else's smart contracts and validators. That claim introduces two things plain staking does not have: contract risk, because a bug in the protocol can impair everyone's claim at once, and market risk, because the price people will pay for stETH on an exchange can drift below the value of the ETH backing it. That drift is called a depeg, and it is not theoretical. In June 2022, during the Celsius and Three Arrows collapse, stETH traded around 0.93 to 0.95 ETH for weeks. Holders who could wait were fine. Holders who had to sell, or who had borrowed against stETH, took the loss in real money.

Restaking, popularized by EigenLayer, lets staked ETH or liquid staking tokens secure additional services on top of Ethereum. These services, called AVSs (actively validated services), include oracle networks, data availability layers, and bridges. They need economic security but do not have their own validator sets, so they rent yours. You delegate to an operator, the operator runs the AVS software, the AVS pays rewards, and in exchange your stake becomes slashable under that AVS's rules as well as Ethereum's.

This last part stopped being hypothetical on April 17, 2025, when EigenLayer's slashing went live on mainnet. Since then, each AVS defines its own slashing conditions, and there is no standard framework across them. One service might penalize downtime, another incorrect attestations, another missed cryptographic duties. Your operator's mundane mistakes, an outdated key, a buggy client, count too. Every additional AVS your operator opts into is an additional rulebook under which your ETH can be destroyed, run by a team you have probably never evaluated.

Doing restaking manually means picking operators and AVSs yourself. Liquid restaking tokens, LRTs, do it for you. You deposit ETH or an LST into a protocol like Kelp (rsETH), ether.fi (eETH and weETH), or Renzo (ezETH), and receive a single token representing a managed basket of restaked positions. The protocol picks the operators, the AVSs, and the risk parameters. You inherit every one of those choices without making any of them.

That convenience is exactly what concentrates the risk. An LRT holder is exposed to the LRT protocol's contracts, the restaking layer's contracts, the LST's contracts underneath if the deposit route used one, the operator set's competence, and every AVS in the basket. Many LRTs are also bridged to other chains so they can be used in DeFi there, which adds a bridge to the stack. Remember that word, bridge. It matters in the next section but one.

Take a typical 2026 LRT dashboard number, say 10 to 12 percent, and pull it apart. The base Ethereum staking layer contributes roughly 3 percent. Actual AVS reward payments, real fees paid by real services, have generally added a few percent at most; analyses through 2025 and 2026 put the honest combined figure for staking plus restaking somewhere around 4 to 7 percent. Everything above that line is one of three things: incentive emissions in the protocol's own token, points programs whose value depends entirely on a future airdrop that may disappoint, or a looped position where the platform has borrowed against your deposit to buy more of the same exposure.

A useful discipline: for every percentage point of advertised yield, name the counterparty who pays it and their reason for paying. Issuance is paid by the network to secure it. AVS fees are paid by services to rent security. Points are paid by nobody yet. If you cannot complete the sentence for a chunk of the APY, that chunk is not yield, it is your own risk premium being marketed back to you.

Lay the layers out and the picture is clear. Plain staking has one slashing regime and, if you self stake, no contract intermediary. Liquid staking adds a smart contract layer and a market price that can detach from backing. Restaking adds N more slashing regimes, one per AVS, plus operator risk. LRTs add another contract layer and delegate all the choices. Bridged LRTs add cross chain messaging on top.

The uncomfortable property of this stack is correlation. These risks do not fail independently on quiet days, they fail together under stress. A slashing event or exploit anywhere in the basket dents confidence in the token, the token depegs, the depeg triggers liquidations of looped positions, forced selling deepens the depeg, and lending markets freeze the collateral. Each layer's failure is the next layer's trigger. That is not a hypothetical chain of reasoning. It is a description of April 2026.

On April 18, 2026, an attacker drained about 116,500 rsETH, worth roughly 290 million dollars, from Kelp DAO's cross chain bridge, the largest DeFi exploit of the year to that point. The failure was not in staking, not in restaking, and not in any AVS. It was the bridge. The LayerZero based setup relied on a 1 of 1 verifier configuration, a single node checking cross chain messages. Attackers, later attributed to North Korea's Lazarus Group, compromised infrastructure nodes, knocked the honest data sources offline with a denial of service attack, forced a failover to nodes they controlled, and injected fake messages that released funds across some 20 chains.

The aftermath is the real lesson. Aave froze rsETH markets within hours. The attacker deposited most of the stolen rsETH into Aave as collateral and borrowed roughly 190 million dollars in ETH and related assets against it, weaponizing the exact looping mechanics covered below. Holders of bridged rsETH on other chains found their tokens stranded or discounted through no action of their own. If you hold an LRT anywhere, you are exposed to its weakest deployment on any chain, and the weakest link is usually the plumbing nobody reads about, not the headline protocol.

The recursive strategy behind many double digit APYs works like this: deposit an LST or LRT into a lending market as collateral, borrow ETH against it, use the borrowed ETH to mint more of the same token, deposit that, borrow again. Three or four loops can turn a 4 percent position into a 12 percent one. The catch is symmetry. The loop multiplies the depeg exposure by the same factor it multiplies the yield. A 5 percent depeg on a 3x looped position is a 15 percent hit to your equity, and lending markets do not wait politely, they liquidate at a penalty, and mass liquidations push the price down further, liquidating the next tier of borrowers.

Edge case worth knowing: some vault products loop on your behalf without saying so plainly. If a strategy's APY meaningfully exceeds the sum of its named yield sources, assume there is borrowing inside it and read the docs until you find it.

Exiting these positions has two doors. The primary door is protocol withdrawal: redeem the token for underlying ETH at full value, but wait through a queue. Liquid staking withdrawals typically clear in hours to days in normal conditions. LRT withdrawals also have to unwind through the restaking layer's withdrawal delay, which is measured in days by design, precisely so slashing can be applied before funds leave. The secondary door is instant: sell the token on the open market at whatever price it fetches. In calm markets the discount is negligible. In a crisis, when everyone wants the instant door, the discount is largest exactly when you most want out. If your plan assumes you can exit at par during stress, you do not have a plan.

Work through these questions honestly. First, can you name the payer behind every percentage point of the advertised yield? If not, stop at plain staking. Second, if the token depegged 10 percent tomorrow, would anything in your setup force action, a loan, a loop, a margin position? If yes, you are carrying liquidation risk, not just yield risk. Third, is a meaningful share of the return points or emissions? Then you are farming a speculation, which is a legitimate activity but not passive income, size it like a speculation. Fourth, is this money you would mind losing entirely?

For most holders, the answer that falls out is boring: plain staking, done carefully, captures the reliable part of the yield with one risk layer instead of five. Our step by step staking guide covers that path. If you still want restaking exposure after all of the above, some damage limits: keep it under 10 percent of your ETH position, use one established protocol rather than chasing the top APY, hold the token on Ethereum mainnet rather than bridged versions, never loop it, and check which AVSs your deposit actually secures at least once a quarter, because the basket changes without asking you.
