What Is LRTfi?

LRTfi is the DeFi ecosystem built on liquid restaking tokens (LRTs), where restaked ETH becomes a tradable token you can use as collateral, lend, or provide as liquidity.

The “LRT” is the token you hold after restaking. The “fi” is the finance layer bolted on top of it. Put them together and LRTfi describes a whole sub-sector, not a single app or coin, in the same way LSTfi describes the DeFi built around liquid staking tokens.

It grew straight out of restaking. Once EigenLayer let people re-pledge staked ETH to secure extra services, protocols started minting liquid tokens for those positions. Then DeFi did what DeFi always does and found ways to lend against them, loop them, and farm points with them. This guide walks the stack from staked ETH to an LRT, shows where the yield actually hides, and gets honest about what can go wrong before you chase any headline APY.

Key Takeaways

• LRTfi is the DeFi layer built on liquid restaking tokens, not a single protocol or coin.
• An LRT is a receipt for restaked ETH that you can move, trade, or use across DeFi.
• The yield stacks from four sources, and the biggest headline number is often speculative points.
• Risk stacks the same way, because you take on Ethereum, restaking, and LRT-protocol risk at once.
• Choosing an LRT should start with exit and depeg risk, not the advertised return.

What LRTfi Means In Crypto

LRTfi is the finance stack built on top of liquid restaking tokens. Someone restakes ETH, receives a liquid token for that position, and then that token gets used across lending markets, liquidity pools, and leverage strategies. All of that activity, taken together, is LRTfi.

The name follows a pattern you have probably seen on Crypto Twitter. LSTfi was the DeFi built on liquid staking tokens like stETH. LRTfi is the next layer up, built on restaking tokens like eETH and ezETH. Same shape, one more level of risk and reward.

It helps to keep three things separate. Restaking is the base action. An LRT is the token you get for it. LRTfi is everything DeFi builds around that token. People blur these three constantly, which is why the sector feels more confusing than it really is.

None of this existed before restaking made ETH reusable as security. That is the thread to hold onto as you read the rest of this page.

How LRTfi Works: From Staked ETH To A Restaking Token

LRTfi works by turning restaked ETH into a token, then pushing that token into DeFi. The pipeline has a fixed order, and picturing it once makes the whole sector click.

It starts with ETH. You either bring native ETH or an existing liquid staking token like stETH. That capital first secures Ethereum through normal proof-of-stake validation, which is the same job liquid staking already does.

Then comes the restaking step. A protocol like EigenLayer or Symbiotic lets that same staked ETH also secure extra services, known as Actively Validated Services or AVSs. These are things like oracles, bridges, and data layers that pay for security. Your ETH is now doing two jobs at once.

For that restaked position, the protocol mints a liquid restaking token. Ether.fi gives you eETH, Renzo gives you ezETH, Kelp gives you rsETH. The LRT is a receipt. It represents your restaked ETH plus every reward attached to it, and it moves freely in your wallet.

The final step is where the “fi” arrives. You take that LRT and deploy it in DeFi.

Common uses look like this:

• Post the LRT as collateral to borrow against it.
• Supply it to a lending market to earn interest.
• Pair it in a liquidity pool for trading fees.

So one deposit of ETH ends up secured on Ethereum, restaked to AVSs, wrapped in a token, and working a fourth time in DeFi. The yield stacks because the jobs stack. Just remember the risk stacks the exact same way, which is the point the rest of this guide keeps returning to.

LRT Vs LST: How Liquid Restaking Tokens Differ

The most common beginner question in this sector is simple. What is the actual difference between stETH and eETH, or between an LST and an LRT? The short version is that an LRT does everything an LST does, then adds one more layer of security duty on top.

A liquid staking token secures Ethereum and nothing else. You stake, you get a token like stETH, and it earns the base validator reward. The risk is mostly Ethereum plus the staking protocol. It is the calmer, older design.

A liquid restaking token re-pledges that same stake to secure extra services. So it earns the base reward plus AVS rewards, but it also inherits slashing conditions from every service it secures. More yield, more surfaces that can fail.

Here is the split at a glance.

Feature	Liquid Staking Token (LST)
What it secures	Ethereum validation only
Yield source	Base staking rewards
Extra reward layer	None beyond staking
Slashing exposure	Ethereum consensus faults only
Relative risk	Lower, single layer

And the restaking equivalent.

Feature	Liquid Restaking Token (LRT)
What it secures	Ethereum plus AVSs
Yield source	Staking plus restaking rewards
Extra reward layer	AVS fees, points, and airdrops
Slashing exposure	Ethereum plus every AVS secured
Relative risk	Higher, stacked layers

The takeaway is not that one is good and one is bad. It is that an LRT is a leveraged version of an LST in terms of both reward and risk. If you already understand LSTs, you understand most of an LRT, then you add restaking risk on top.

Where LRTfi Yield Actually Comes From

Screenshots of “50% APY” get passed around every cycle, so it pays to break the number apart. LRTfi yield is not one thing. It is four separate sources stacked into a single headline figure, and they are not equally real.

Before the bullets, here is the honest framing. Some of that yield is paid in ETH and settles today. Some of it is a bet on tokens that may or may not arrive.

The four layers usually look like this:

• Base ETH staking yield from securing Ethereum, paid in real terms.
• AVS restaking rewards for securing extra services, real but variable.
• DeFi yield from deploying the LRT as collateral, in lending, or in liquidity pools.
• Points and expected future airdrops, which are speculative until a token actually lands.

The first three are grounded. The fourth is where people get burned. Much of the eye-catching APY through 2024 and 2025 was really an implied value for airdrop points, not cash in hand. When Ether.fi ran its ETHFI airdrop, that season ended, and a lot of farmers learned their “yield” had been a one-time bet all along.

So when you see a big LRTfi number, split it. Ask how much is ETH-denominated staking and DeFi yield you can actually withdraw, and how much is a points multiplier priced off an airdrop that has not happened yet. The real yield is usually solid but modest. The exciting part is usually the speculative part, and it can go to zero the day the token unlocks.

The Real Risks In LRTfi: Slashing, Depeg, And Looping

Here is the question underneath everything: can you actually lose your ETH? Yes, you can. LRTfi does not remove risk, it stacks it, and by 2026 several of those risks are no longer theoretical.

Start with smart-contract risk, because you take on three layers at once. Your funds depend on Ethereum, on the restaking protocol like EigenLayer, and on the LRT protocol that minted your token. A bug or exploit in any one of those can hit your position. Three doors instead of one.

Slashing is the layer that changed. On EigenLayer, slashing is now live, which means an AVS can penalize the stake securing it if operators misbehave. That penalty flows down to the restaked ETH backing your LRT. The yield you were paid for taking AVS risk is real risk, not a free lunch.

Then there is depeg. An LRT is only worth its ETH backing if you can redeem or sell near that value. Under stress, that breaks.

> In April 2024, Renzo’s ezETH briefly lost its peg when exit liquidity dried up during a farming rush. Holders who wanted out found that “liquid” stopped meaning liquid at the worst moment, and leveraged positions were liquidated in the drop.

Looping is where moderate risk turns into liquidation risk. The strategy is recursive: deposit an LRT, borrow against it, buy more of the LRT, deposit again, repeat. It multiplies points and yield, but it is leverage, and leverage has a cost. When borrow rates spike or the LRT dips, looped positions unwind fast. If you have watched how funding costs punish leveraged trades, this is the same trap in a restaking wrapper.

The practical rule is to lead with exit risk, not APY. Before you deposit, ask how deep the LRT’s liquidity is and how quickly you could get back to plain ETH in a panic. If the honest answer is “slowly,” the headline yield does not matter.

The LRTfi Ecosystem: Protocols And Tokens To Know

Once you know the shape, the names on your timeline stop being noise. The LRTfi map has two layers: the restaking protocols underneath and the LRT issuers on top of them.

Underneath sit the restaking layers themselves. EigenLayer is the original and by far the largest, the base that most LRTs restake into. Symbiotic is the main alternative, a more modular restaking design that some newer issuers use to avoid single-protocol dependence.

On top sit the issuers, each with its own LRT ticker. These are the tokens you actually hold and use across DeFi.

Here is the who’s-who.

Protocol	Liquid Restaking Token
Ether.fi	eETH / weETH
Renzo	ezETH
Kelp DAO	rsETH
Puffer Finance	pufETH

There is one risk this table hides: concentration. Because most of these LRTs restake through EigenLayer, a serious failure there would not hit one token, it would ripple through the whole sector at once. Diversifying across three LRTs does little if all three sit on the same base.

This naming pattern is worth clocking too. LRTfi sits beside sibling “-fi” sectors like onchain AI agents, and understanding how one sub-sector forms makes the next crypto acronym far less intimidating.

Should You Use LRTfi? Who It Fits And Who It Doesn’t

LRTfi is not for everyone, and that is a feature, not a knock. It fits a specific user and quietly punishes the wrong one.

It fits you if you already stake ETH, understand how DeFi collateral and liquidations work, and can genuinely stomach smart-contract and depeg risk. If losing part of a position to a bug or a depeg would not force you into a fire sale, you are the intended user. The extra restaking yield is a fair trade for someone who reads the risks and still wants in.

It does not fit you if you want simple, low-drama ETH exposure. If your goal is to stake, forget about it, and sleep, native staking or a plain LST does that job with fewer moving parts. Adding restaking and DeFi loops on top just buys you complexity you did not want.

If you decide it fits, run a short pre-deposit check.

• How deep is the LRT’s onchain liquidity, and how fast could you exit to ETH?
• Which lending markets and pools actually integrate this LRT?
• Are you touching leverage or looping, or staying unleveraged?

One practical note. Holding and moving LRTs safely means real self-custody, so a solid self-custody wallet is a genuine prerequisite before your first deposit, not an afterthought.

FAQ

What does LRTfi stand for in crypto?

LRTfi stands for liquid restaking token finance. The “LRT” is the liquid restaking token you receive when you restake ETH, and the “fi” is the DeFi layer built around it. So LRTfi is a whole sector, meaning all the lending, borrowing, and liquidity activity around liquid restaking tokens, not a single protocol or coin.

How is LRTfi different from LSTfi?

LSTfi is DeFi built on liquid staking tokens like stETH, which only secure Ethereum. LRTfi is built on liquid restaking tokens like eETH, which secure Ethereum plus extra services called AVSs. So LRTfi adds one more layer of yield and one more layer of slashing and depeg risk on top of the LSTfi model.

Is LRTfi safe, or can I lose my ETH?

You can lose ETH in LRTfi. It stacks smart-contract risk across Ethereum, the restaking protocol, and the LRT protocol, plus live slashing and depeg risk. It is not a savings account. LRTfi can suit users who understand DeFi risk, but anyone wanting simple, low-risk ETH exposure is better off with native staking.

Where does LRTfi yield actually come from?

LRTfi yield comes from four stacked sources: base ETH staking rewards, AVS restaking rewards, DeFi yield from deploying the LRT, and speculative points or future airdrops. The first three are real and mostly ETH-denominated. The fourth is a bet on a token that may never arrive, and it inflates many headline APYs.

Which liquid restaking tokens power LRTfi?

The most-used LRTs in LRTfi are Ether.fi’s eETH and weETH, Renzo’s ezETH, Kelp DAO’s rsETH, and Puffer’s pufETH. Most restake through EigenLayer, with Symbiotic as the main alternative. Because so many LRTs share EigenLayer underneath, concentration risk in LRTfi is real even when you hold several different tokens.

Where To Start

If LRTfi still looks worth exploring after the risk section, move slowly and in order.

• Confirm you understand plain liquid staking first, since an LRT is just that with restaking added.
• Pick one LRT and check its real onchain liquidity and how fast you could exit to ETH.
• Split any advertised APY into ETH-denominated yield versus speculative points before you deposit.
• Start unleveraged and skip looping until you have watched an LRT hold its peg through a rough week.
• Keep your LRTs in a wallet you control, and treat concentration in EigenLayer as a single point of failure.
