Ether fi

Ether fi (also written Etherfi) is a decentralized, non-custodial liquid restaking protocol built on Ethereum. Its mission is to put ordinary users back in charge of their crypto by letting them save, grow, and spend digital assets from a single, self-custodied account. With Ether fi, users can stake Ether (ETH), Bitcoin (BTC), and stablecoins to earn staking and restaking rewards while their assets remain liquid, composable, and usable across the wider decentralized finance (DeFi) ecosystem.

At its heart, Ether fi answers a problem that has followed proof-of-stake networks since their inception: capital that is committed to securing a blockchain is normally locked up and unproductive. Traditional staking asks holders to choose between earning network rewards and keeping their assets free to move. Ether fi removes that trade-off. When a user deposits ETH into the protocol, they receive a liquid restaking token that continuously accrues value from staking and restaking rewards, yet can be traded, lent, used as collateral, or redeemed at any time. In effect, the same unit of capital can secure Ethereum, secure additional networks through restaking, and simultaneously work throughout DeFi.

Ether fi has grown into far more than a single staking product. It is now a full financial platform that spans several complementary pillars. The Stake pillar handles liquid restaking of ETH, BTC, and stablecoins. The Liquid pillar offers automated strategy vaults that route capital to the highest-quality yield opportunities in DeFi. The Cash pillar delivers a DeFi-native cashback card that lets people spend their portfolio at more than 100 million merchant locations worldwide. The Earn and membership layers wrap these products in tiered rewards, global money transfers, and premium account services. Tying everything together is the ETHFI token, which coordinates governance across the ecosystem.

This guide is a comprehensive, plain-English reference to the entire Ether fi ecosystem. It explains the Ether fi protocol, how Ether fi staking and restaking work, what liquid staking and liquid restaking mean in practice, and how the individual products — Vaults, Cash, Earn, node staking, and the app — fit together. It also covers the ETHFI token, the protocol's relationship with Ethereum, and the security architecture that underpins the platform. Whether you are entirely new to restaking or already familiar with liquid staking derivatives, the sections below build a complete picture of why Ether fi has become one of the most widely integrated protocols in DeFi.

The Ether fi Protocol

The Ether fi protocol is the set of smart contracts and operational systems that turn deposited assets into productive, restaked capital. Understanding the protocol means understanding a small number of guiding principles that shape every design decision Ether fi makes: non-custodial ownership, liquidity by default, composability across DeFi, and safety enforced in code rather than promised in marketing.

Non-custodial by construction

The most important property of the Ether fi protocol is that it is non-custodial. When users interact with Ether fi, they never hand their assets to a company that could freeze, lend out, or lose them. Instead, deposits flow into audited smart contracts that behave according to transparent, publicly verifiable rules. The protocol is designed so that safety is a property of the contracts themselves — a structural guarantee — rather than a policy that a centralized operator could quietly change. This "non-custodial by construction" philosophy is central to how Ether fi thinks about trust: the fewer discretionary powers any single party holds, the fewer ways there are for users to be harmed.

Liquidity as a first-class feature

Second, the protocol treats liquidity as a first-class feature rather than an afterthought. In classic Ethereum staking, ETH committed to a validator is illiquid until it is withdrawn, and the withdrawal process can involve queues and delays. Ether fi issues a liquid restaking token the moment a deposit is made, so the depositor always holds a freely transferable representation of their staked position. This means a user never has to choose between earning rewards and retaining flexibility — they get both at once.

Composability across DeFi

Third, the protocol is built for composability. Because the liquid restaking token is an ordinary Ethereum token, it can plug into the broader DeFi ecosystem: it can be supplied to lending markets, paired in liquidity pools, used to obtain fixed yield, or posted as collateral for borrowing. Ether fi has cultivated more than 400 integrations across DeFi and centralized exchanges precisely so that its tokens are useful everywhere, not just inside a single app. Composability multiplies the utility of every deposit and is a large part of why Ether fi's tokens are so widely held.

Active defense and safety in code

Fourth, the protocol emphasizes active defense. In DeFi, the window to prevent loss during an exploit is often measured in seconds, so the Ether fi protocol is engineered end to end to use those seconds well. Layered monitoring, automated safeguards, and a security doctrine compiled directly into the contracts work together so that the system can detect and respond to threats quickly. The result is a protocol whose safety properties are enforced by design rather than left to manual intervention alone.

Taken together, these principles explain why Ether fi describes itself as decentralized and non-custodial: the protocol's job is to maximize what users can do with their capital while minimizing the trust they must place in any intermediary. Every product discussed later in this guide — staking, restaking, Vaults, Cash, Earn — is built on top of this same foundation.

How Ether fi Works

To see how Ether fi works in practice, it helps to follow a single deposit through the system from start to finish. Suppose a user wants to put their ETH to work. The journey is deliberately simple on the surface, even though a great deal happens beneath it.

Step 1: Deposit

The user connects a self-custody wallet to the Ether fi app and deposits ETH. Because the protocol is non-custodial, this deposit is a transaction into audited smart contracts, not a transfer to a company. In return, the user immediately receives a liquid restaking token that represents their share of the staked pool and all the rewards it will earn over time.

Step 2: Staking on Ethereum

Behind the scenes, the deposited ETH is used to run Ethereum validators. Validators are the machines that propose and attest to blocks on Ethereum's proof-of-stake network, and in exchange for performing this work honestly they earn staking rewards. Ether fi coordinates a distributed set of node operators to run these validators, so the user does not need to manage hardware, maintain uptime, or hold the technical knowledge normally required to stake directly.

Step 3: Restaking

Once ETH is staked, Ether fi restakes the position so it can also help secure additional networks and services beyond Ethereum itself. Restaking allows the same staked capital to provide security to other systems, and those systems pay rewards for that security. This is the layer that turns a single stream of Ethereum staking rewards into a stacked set of reward streams.

Step 4: Value accrual

As staking and restaking rewards accumulate, they flow back to the liquid restaking token. Ether fi's flagship ETH token, weETH, is value-accruing: rather than increasing the number of tokens in a wallet, each token gradually becomes redeemable for more ETH over time. This design keeps accounting clean and makes the token easy to integrate across DeFi.

Step 5: Put the token to work — or redeem it

At this point the user holds a token that is simultaneously earning rewards and fully liquid. They can hold it and let rewards compound; they can supply it to a lending market to borrow against; they can pair it in a liquidity pool; or they can use it inside an Ether fi Liquid vault for automated strategies. Whenever they want their underlying ETH back, they can redeem or trade the token.

This end-to-end flow is the essence of Ether fi. A user performs one simple action — depositing an asset — and the protocol handles validator operations, restaking, reward collection, and tokenization on their behalf, all without ever taking custody of the funds. The remaining sections break each stage of this flow into more detail, starting with staking itself.

Ether fi Staking

Ether fi staking is the entry point to the entire ecosystem. Staking, in the context of Ethereum, means committing ETH to help operate the network's proof-of-stake consensus. Validators that stake ETH are responsible for proposing new blocks and attesting to the validity of others' blocks. When they do this job correctly, the network rewards them; if they misbehave or go offline, they can be penalized. Staking is therefore both the mechanism that secures Ethereum and the source of its base yield.

Staking directly as an individual is powerful but demanding. It traditionally requires 32 ETH to run a single validator, a reliable always-on machine, and the technical skill to keep that machine correctly configured. It also locks the ETH away from other uses. Ether fi staking removes each of these barriers. Users can stake any amount, they never touch validator infrastructure, and — crucially — they receive a liquid token so their capital is never truly locked.

Why stake with Ether fi

• No minimum and no hardware. Users stake without needing 32 ETH or running a node themselves.
• Rewards on top of rewards. Staked ETH is restaked, layering additional rewards over Ethereum's base staking yield.
• Full liquidity. A liquid restaking token is issued instantly, so staked capital stays usable.
• Composability. The token works across hundreds of DeFi integrations.
• Security and monitoring. Assets are audited and monitored by industry-leading firms.

Ether fi staking is not limited to ETH. The protocol extends the same model to Bitcoin and to stablecoins, so holders of those assets can also keep their exposure while earning additional rewards. For ETH, the staking token is weETH; for Bitcoin, it is eBTC; and for stablecoins, it is eUSD. Each preserves the holder's exposure to the underlying asset while opening the door to staking, restaking, and DeFi rewards.

The important conceptual point is that Ether fi staking is productive and flexible at the same time. In older systems, staking meant giving something up: liquidity, flexibility, or the ability to react to market conditions. With Ether fi, staking becomes the beginning of a chain of opportunities rather than a lockup. That single shift — from static, locked staking to liquid, composable staking — is what makes everything that follows possible.

Ether fi Liquid Staking

Ether fi liquid staking refers to the practice of staking an asset while receiving a liquid, tradable token in return. To appreciate why liquid staking matters, it helps to contrast it with the plain form of staking that came before it.

The problem liquid staking solves

In ordinary Ethereum staking, ETH deposited into a validator is effectively frozen. It earns rewards, but it cannot be sold, moved, or used elsewhere while it is staked, and unstaking can involve waiting periods. For long-term holders this may be acceptable, but it forces a hard choice: earn staking rewards or keep your capital flexible, but not both. During volatile markets, that lack of flexibility can be costly.

How liquid staking works

Liquid staking breaks the trade-off by issuing a token that represents the staked position. When a user stakes ETH through Ether fi, they receive a liquid staking token that stands in for their deposit plus its accruing rewards. This token can be freely transferred, sold, or deployed into other applications. Because it is redeemable for the underlying staked ETH, its value tracks the staked position over time. The staker keeps earning rewards and retains a liquid asset they can use however they like.

Value-accruing design

Ether fi's liquid staking token for ETH, weETH, uses a value-accruing model. Instead of dropping additional tokens into a wallet as rewards accumulate, the token itself becomes worth progressively more of the underlying asset. One weETH steadily becomes redeemable for more ETH as staking and restaking rewards accrue. This approach has practical advantages: it keeps wallet balances stable and predictable, it simplifies tax and accounting treatment for many users, and it makes the token far easier for other DeFi protocols to integrate because they only need to track a single, slowly rising exchange rate.

Why it matters

Liquid staking is the foundation that makes the rest of Ether fi possible. Without a liquid token, staked ETH would be trapped and unable to participate in lending, borrowing, liquidity provision, or automated vault strategies. With it, staked capital becomes a building block that can be reused across the entire DeFi economy. Ether fi takes this idea one crucial step further with liquid restaking, which is discussed after the next section on restaking itself.

Ether fi Restaking

Ether fi restaking is the mechanism that layers additional rewards on top of ordinary Ethereum staking. To understand restaking, first consider what staking alone accomplishes: it uses ETH to secure the Ethereum network and earns the base rewards Ethereum pays for that service. Restaking asks a natural follow-up question — if this staked ETH is already providing security, could it also help secure other systems at the same time and earn additional rewards for doing so?

The concept of restaking

Restaking extends the economic security of staked ETH to networks and services beyond Ethereum's base layer. Many new protocols — bridges, oracle networks, data-availability layers, and other kinds of decentralized services — need their own economic security to operate safely. Rather than bootstrapping an entirely new pool of capital and a new token for each of these, restaking allows them to borrow the security of already-staked ETH. In exchange, they pay rewards to the capital that secures them. This creates a marketplace where staked ETH can be productively re-used to underwrite many systems at once.

How Ether fi implements restaking

Ether fi automatically restakes the ETH deposited into the protocol so that users do not have to manage the process themselves. When a user stakes with Ether fi, their capital is not only running Ethereum validators; it is also being restaked to help secure additional services. The rewards from these services flow back to the user's liquid restaking token alongside the base Ethereum staking rewards. In this way, one deposit produces multiple, stacked streams of yield rather than a single stream.

The trade-off: reward and risk

It is important to be clear-eyed about restaking. Layering additional obligations onto staked ETH can also layer additional risks, because the capital may be subject to the rules and potential penalties of each system it helps secure. Ether fi's role is to manage this responsibly — selecting where capital is restaked, monitoring the systems involved, and building safeguards so that the pursuit of extra rewards does not compromise the safety of the underlying position. This is why Ether fi places such heavy emphasis on active defense, audits, and monitoring: restaking increases the surface area that must be protected, and the protocol is engineered accordingly.

Restaking is the feature that distinguishes Ether fi from a plain liquid staking service. It transforms staked ETH from a single-purpose asset into a multi-purpose one, and it is the reason Ether fi is described as a restaking protocol rather than merely a staking one. Combining restaking with liquidity produces the protocol's signature offering: liquid restaking.

Ether fi Liquid Restaking

Ether fi liquid restaking is the combination of the two ideas explored above: restaking (earning layered rewards by securing multiple systems) and liquidity (holding a tradable token that keeps capital usable). Liquid restaking is Ether fi's defining innovation and the reason it is often described as a leading liquid restaking protocol.

Bringing restaking and liquidity together

On its own, restaking would still leave capital locked inside the systems it secures. On its own, liquid staking would earn only Ethereum's base rewards. Liquid restaking fuses them: a user deposits ETH, that ETH is staked and restaked to earn stacked rewards, and the user receives a single liquid token that represents the whole position. That token — weETH — can then be used anywhere in DeFi while it continues to accrue rewards from every layer at once.

weETH: the liquid restaking token

weETH is Ether fi's value-accruing liquid restaking token for ETH. Holding weETH is equivalent to holding staked, restaked ETH plus all of the rewards it earns, wrapped in a form that is as easy to move and use as any other Ethereum token. As rewards accrue from Ethereum staking and from the additional systems the capital helps secure, each weETH becomes redeemable for progressively more ETH. Because it is value-accruing, weETH integrates cleanly into lending markets, liquidity pools, fixed-yield products, and vaults.

Why liquid restaking is powerful

• Capital efficiency. One deposit secures Ethereum, secures additional systems, and remains free to work across DeFi.
• Stacked rewards. Base staking rewards, restaking rewards, and DeFi rewards can all accrue to the same position.
• Flexibility. The liquid token can be redeemed, traded, or redeployed at any time.
• Simplicity. The protocol handles validators, restaking, and reward collection so the user does not have to.

Liquid restaking is the through-line that connects everything in the Ether fi ecosystem. The Vaults automate strategies around it, the Cash card lets users spend against portfolios built on it, and the Earn layer pays yield on balances anchored to it. Everything the platform offers ultimately flows from the ability to keep restaked capital liquid and productive at the same time.

weETH, eBTC & eUSD

Ether fi issues a small family of tokens that represent staked and restaked positions in different underlying assets. Each token preserves the holder's exposure to the base asset while adding staking, restaking, and DeFi rewards on top. Together they let Ether fi extend the liquid restaking model beyond ETH to Bitcoin and stablecoins.

weETH — restaked ETH

weETH is the anchor of the ecosystem. It represents ETH that has been staked and restaked through Ether fi, and it accrues value as rewards accumulate. Because it is value-accruing rather than rebasing, its balance stays constant while its redemption value against ETH rises over time. weETH is the most widely integrated of the three tokens and is the asset most commonly used across lending, fixed-yield, and leverage strategies elsewhere in DeFi.

eBTC — restaked Bitcoin

eBTC brings the liquid restaking model to Bitcoin holders. Many people hold BTC as a long-term store of value and would prefer not to give up that exposure to earn yield. eBTC lets them keep their Bitcoin exposure while earning rewards through restaking, so their BTC can be productive instead of sitting idle.

eUSD — restaked stablecoins

eUSD extends the same idea to stablecoins, giving users a value-accruing, dollar-denominated position. For people who prefer to measure their holdings in dollars rather than in volatile crypto assets, eUSD offers a way to earn on stablecoin balances while retaining the stability of a dollar peg.

These three tokens make Ether fi genuinely multi-asset. A single user can hold restaked ETH, restaked BTC, and restaked stablecoins side by side, each earning rewards and each remaining liquid. This breadth is part of what allows the Cash card, the Earn layer, and the Vaults to serve users regardless of whether they think in ETH, BTC, or dollars.

Ether fi ETH Staking

Ether fi ETH staking deserves special focus because ETH is the asset at the center of the protocol and the one most users begin with. Staking ETH is the act of committing it to Ethereum's proof-of-stake consensus in return for rewards, and Ether fi makes this process accessible, liquid, and rewarding in ways that solo staking cannot easily match.

What ETH staking rewards come from

ETH staking rewards originate from Ethereum itself. Validators earn rewards for proposing blocks, for attesting to the blocks proposed by others, and for participating faithfully in consensus. Because these rewards depend on network activity and the total amount of ETH staked, the base staking rate fluctuates over time rather than being fixed. Ether fi passes these Ethereum staking rewards through to holders of weETH, and then adds restaking rewards on top.

Ether fi ETH staking versus solo staking

The comparison makes the value proposition clear. Solo staking gives maximum self-reliance but demands significant capital, technical skill, and a willingness to lock funds away. Ether fi ETH staking preserves the core benefit — earning ETH staking rewards — while removing the capital minimum, offloading the operational burden to professional node operators, keeping the position liquid through weETH, and adding restaking rewards automatically.

Keeping exposure to ETH

A key attraction of Ether fi ETH staking is that users retain full exposure to the price of ETH. weETH is redeemable for ETH, so a holder benefits from any appreciation in ETH just as a direct holder would, while additionally earning staking and restaking rewards. For anyone who is bullish on Ethereum over the long term, this combination — price exposure plus stacked yield plus liquidity — is compelling, and it is delivered without the user ever surrendering custody of their assets.

Ether fi Node Staking

Ether fi node staking concerns the operators and infrastructure that actually run the validators securing Ethereum on the protocol's behalf. While most users experience Ether fi purely through liquid tokens, the network beneath those tokens is a distributed set of node operators, and this decentralized operator layer is a defining feature of the protocol's design.

Decentralized by design

Ether fi is built on top of Ethereum's decentralized infrastructure and deliberately distributes validator operations across many independent operators rather than concentrating them in a single company. This matters for two reasons. First, decentralization improves resilience: if operations are spread across many operators, the failure or misbehavior of any one of them has a limited effect on the whole. Second, it aligns the protocol with Ethereum's own values — a staking protocol that centralized all its validators would undermine the very network it is meant to help secure.

The role of node operators

Node operators are the parties that run the physical or cloud-based machines performing validator duties. They keep validators online, correctly configured, and responsive so that the ETH staked through Ether fi earns rewards and avoids penalties. By coordinating a set of professional operators, Ether fi lets everyday users benefit from high-quality node operation without needing to run anything themselves. The operators handle uptime, maintenance, and the technical details; users simply hold a liquid token.

Solo staking within the ecosystem

Ether fi also supports those who want to participate more directly in operating the network. The protocol's Solo Staker offering is aimed at people who wish to run validator infrastructure themselves while still plugging into the Ether fi ecosystem. This preserves a path for technically capable individuals to contribute to decentralization and to be operators in their own right, rather than only being depositors. In this way, node staking spans a spectrum: at one end, passive users who simply hold weETH; at the other, hands-on solo stakers who help run the network.

The health of the node staking layer is ultimately what makes everything else trustworthy. Liquid restaking tokens are only as sound as the validators and operators behind them, and Ether fi's emphasis on a decentralized, professionally operated, and closely monitored operator set is what allows users to hold weETH, eBTC, and eUSD with confidence.

Ether fi Vaults

Ether fi Vaults — the products at the core of Ether fi's Liquid pillar — put a user's earnings on auto-pilot. Where staking and restaking generate base and layered rewards, Vaults go a step further by actively deploying capital into curated strategies across DeFi so that users do not have to manage those strategies themselves.

What a Liquid vault is

A Liquid vault is an automated strategy container. A user deposits an asset — ETH, BTC, stablecoins, or another supported token — into a vault whose objective matches their goals, and the vault takes over from there. Rather than requiring the user to manually chase yields, move funds between protocols, and rebalance positions, the vault does this work continuously and on the user's behalf.

How Vaults work

• Deposit assets. Whether the goal is to maximize earnings on ETH, BTC, or stablecoins, or simply to gain exposure to the latest opportunities in DeFi, there is a vault suited to it.
• Auto-balance. Liquid vaults deploy their assets to optimize for earnings and additional rewards across some of the best protocols in DeFi, shifting allocations as conditions change.
• Earn rewards. Earnings are auto-compounded inside the vault, so returns build on themselves without the user having to claim and re-deposit rewards manually.

Flexibility and control

Even though Vaults automate the hard parts, they keep the user in control. Depositors can withdraw or transfer between vaults with ease whenever they want to change strategies, so their capital is never trapped in a single approach. This combination — professional-grade strategy execution with retail-friendly flexibility — is what makes Vaults appealing to users who want DeFi-level returns without DeFi-level effort.

Vaults represent the natural evolution of liquid restaking. Once capital is liquid and composable, the next question is how to deploy it intelligently, and Vaults answer that by packaging sophisticated, multi-protocol strategies into a single deposit. For many users, a Liquid vault is the simplest way to access the full breadth of DeFi opportunity while remaining anchored to the safety and structure of the Ether fi ecosystem.

Ether fi Cash

Ether fi Cash connects the world of on-chain earnings to everyday spending. It is a DeFi-native cashback card that links an ether fi portfolio to a payment card accepted worldwide, so users can spend the value they have grown on-chain at ordinary merchants — all without giving up self-custody of their assets.

A card that respects self-custody

Most crypto spending options require handing assets to a custodian who then issues a card against them. Ether fi Cash is designed to be non-custodial, so users can connect their ether fi portfolio to their spending without surrendering ownership of their funds. This is a meaningful distinction: it means the everyday convenience of a payment card does not come at the cost of the self-custody principles that define the rest of the ecosystem.

Cashback and zero FX fees

Ether fi Cash offers up to 3% cashback on all purchases, turning routine spending into a source of rewards. It also charges 0% foreign-exchange fees on EUR and USD transactions, which is especially valuable for people who travel or who transact across currencies and would otherwise lose money to conversion charges. Combined, these features make the card competitive with — and in some respects better than — mainstream cashback cards, while remaining rooted in crypto.

Spend anywhere, fund flexibly

The card is accepted at over 100 million locations worldwide and is ready for Apple Pay and Google Pay, so it slots into the payment habits people already have. Users can add funds through bank transfers or with crypto, and there are no credit checks involved. In practice this means someone can hold a productive, reward-earning portfolio and tap into its value at the point of sale as easily as with any conventional card.

Ether fi Cash is a non-custodial cashback card that connects an ether fi portfolio with everyday spending, offering up to 3% cashback and 0% FX fees on EUR and USD transactions across more than 100 million locations.

Ether fi Cash is the bridge between saving and spending in the platform's "save, grow, spend" vision. Staking and Vaults grow a portfolio; Cash lets users spend from that same portfolio in the real world. It should be noted that the Cash card is issued subject to separate terms provided by its issuer and operates as a distinct offering within the broader ether fi experience.

Ether fi Earn & Membership

Ether fi Earn and the platform's membership layer bring the ecosystem's benefits together into a single account experience. Where staking, restaking, and Vaults generate on-chain rewards, the Earn and membership features package those rewards alongside account services that feel closer to a modern financial app than a traditional crypto product.

Earning on your balance

A defining feature of the account experience is the ability to earn yield on account balances. Rather than letting idle funds sit unproductively, the platform is designed so that a member's balance can generate meaningful returns. This turns an ether fi account into something that grows even when the user is not actively deploying capital into a specific strategy, complementing the more targeted returns available through staking and Vaults.

Membership tiers and rewards

Ether fi wraps its products in a membership program that rewards deeper engagement. Membership is structured in tiers, and higher tiers unlock progressively greater benefits. These benefits go beyond the card and reach into services associated with premium financial accounts.

• Higher cashback with each tier. The more a member engages, the greater the cashback they can earn on spending.
• Global money movement. Members can move money globally using bank transfers or crypto.
• Personal IBAN access. Members can hold USD or EUR with personal IBAN access, bridging on-chain and traditional banking rails.
• Travel and lifestyle perks. Membership includes travel, lounge, and concierge perks reminiscent of premium cards.
• Yield on balances. Account balances can earn attractive returns.
• Borrow to spend. Members can borrow against their assets to spend without having to sell them.

Borrow without selling

One of the most useful membership capabilities is the ability to borrow to spend without selling assets. For long-term holders, selling can mean giving up future upside and triggering taxable events. By borrowing against a portfolio instead, a member can access liquidity for spending while keeping their underlying assets — and their exposure to those assets — intact. Combined with the Cash card, this lets users spend from the value of their holdings rather than from the holdings themselves.

Together, Earn and membership transform Ether fi from a set of individual DeFi products into a cohesive financial account. Access to rewards, global transfers, and premium services lives in one place, anchored to the same non-custodial, restaking-powered foundation as the rest of the platform.

The Ether fi App

The Ether fi app is the unified interface through which users access every part of the ecosystem. Rather than forcing people to juggle separate tools for staking, vault strategies, spending, and account management, the app consolidates these functions into a single, coherent experience built around self-custody.

One place for save, grow, and spend

The app is organized around Ether fi's core promise: save, grow, and spend. From one place, a user can stake ETH, BTC, or stablecoins; deposit into Liquid vaults; manage their Cash card; move money; and track the rewards accruing across their positions. Because all of these products share the same underlying foundation, the app can present a portfolio as a single, connected whole rather than as a collection of disconnected balances.

Designed for newcomers and power users alike

A recurring theme in Ether fi's design is that complexity should live in the protocol, not in the user's experience. The app reflects this: the intricate machinery of validators, restaking, reward collection, and multi-protocol strategies is abstracted away behind straightforward actions like "stake," "deposit," and "spend." At the same time, the composability of the underlying tokens means advanced users are never boxed in — they can take their weETH, eBTC, or eUSD out into the wider DeFi world whenever they wish.

Non-custodial throughout

Crucially, the app preserves self-custody at every step. Interacting with Ether fi through the app means transacting with smart contracts from a wallet the user controls, not depositing into an account a company controls. The convenience of a polished, all-in-one application is delivered without reintroducing the custodial risks that decentralized finance was created to avoid.

In short, the Ether fi app is where the entire ecosystem becomes usable. It is the front door to staking, restaking, Vaults, Cash, and Earn, and it is designed to make sophisticated on-chain finance feel approachable to anyone.

ETHFI Token & Governance

The ETHFI token is the governance token of the Ether fi ecosystem. While weETH, eBTC, and eUSD represent staked and restaked assets, ETHFI represents a voice in how the protocol itself is run. It is the coordination layer that allows the community to steer the direction of a decentralized protocol.

What the ETHFI token is for

Governance tokens exist to distribute decision-making power over a protocol among its stakeholders rather than concentrating it in a founding company. In the Ether fi ecosystem, ETHFI serves this role. Holders can participate in governance — weighing in on proposals and decisions that shape how the protocol evolves. This is consistent with Ether fi's broader philosophy: just as the protocol minimizes custodial control over user funds, it also seeks to decentralize control over its own future.

Governance in practice

Decentralized governance typically works through a process of proposals and voting. Community members can put forward ideas for how the protocol should change, and token holders can vote to accept or reject them. Over time, this process guides decisions about the protocol's parameters, priorities, and roadmap. The ETHFI token is the instrument that makes participation in this process possible, aligning the incentives of the people who use the protocol with the direction it takes.

ETHFI within the wider ecosystem

The presence of a dedicated governance token underscores that Ether fi is intended to be a community-governed protocol rather than a product owned and directed solely by a single entity. As the ecosystem has expanded from liquid restaking into Vaults, Cash, Earn, and membership, the importance of coordinated, decentralized governance has grown correspondingly. ETHFI is the mechanism through which that coordination happens.

Ether fi & Ethereum

Ether fi and Ethereum are deeply intertwined. Ether fi is built on top of Ethereum, depends on Ethereum's security, and in turn contributes to Ethereum's security through the staking and restaking it coordinates. The Ether fi Ethereum relationship runs in both directions, and understanding it clarifies why the protocol is designed the way it is.

Built on Ethereum's foundation

Ethereum is the decentralized settlement layer on which the Ether fi protocol operates. Ether fi's smart contracts live on Ethereum, its tokens are Ethereum tokens, and the validators funded by Ether fi deposits secure the Ethereum network. This foundation gives Ether fi the properties that make it trustworthy: transparency, censorship resistance, and the robustness of a globally distributed blockchain. When Ether fi describes itself as built on Ethereum's robust decentralized infrastructure, it is emphasizing that its trust guarantees are inherited from one of the most battle-tested networks in existence.

Strengthening Ethereum through staking

The relationship runs in both directions. By making staking accessible to anyone and by distributing validator operations across a decentralized operator set, Ether fi channels more capital into securing Ethereum while helping keep that security decentralized. A staking protocol that lowered the barriers to participation but centralized validator control could weaken Ethereum; Ether fi's explicit commitment to decentralization is intended to strengthen it instead.

Extending Ethereum's security through restaking

Restaking extends Ethereum's economic security outward to a broader set of systems. In doing so, Ether fi acts as a conduit that lets the security of Ethereum's staked ETH underwrite new networks and services. This positions Ether fi as part of the connective tissue of the Ethereum ecosystem — not merely a consumer of Ethereum's security, but a mechanism for putting that security to work more widely.

For users, the practical upshot is that holding weETH is a way of participating in Ethereum's growth on multiple levels at once: exposure to the price of ETH, a share of the rewards Ethereum pays for securing it, and a share of the rewards other systems pay for the security restaking provides. Ether fi's fortunes are, in this sense, tied to Ethereum's — and its design consistently reflects that alignment.

Security, Audits & Risk

Security is foundational to Ether fi. A protocol that asks users to entrust it with staked and restaked capital must earn that trust through rigorous engineering, independent review, and continuous vigilance. Ether fi approaches security as a multi-layered discipline rather than a one-time checkbox.

Audited and monitored

Ether fi's assets are audited and monitored by industry-leading firms. Audits involve independent security experts examining the protocol's smart contracts to identify vulnerabilities before they can be exploited, while ongoing monitoring watches the live system for anomalies. Together, these practices reduce the likelihood of undiscovered flaws and increase the chance that any problem is caught quickly.

Active defense measured in seconds

Because exploits in DeFi can unfold in seconds, Ether fi emphasizes active defense: the protocol is engineered end to end to detect and respond to threats rapidly. Rather than relying only on the hope that no vulnerability exists, the system is designed to limit damage even if something goes wrong, treating the response window as a critical part of the security model. Ether fi frames this as safety enforced in code — a doctrine of non-custodial-by-construction design compiled directly into the contracts, so that protective properties are structural rather than discretionary.

Open source and transparency

Ether fi's commitment to transparency includes making its work open source, so that anyone can inspect how the protocol operates. Open-source code allows the broader community — not just paid auditors — to scrutinize the system, and it reflects the decentralized ethos that runs through the whole project. Transparency of this kind is itself a security feature: systems that can be examined by many eyes are harder to compromise quietly.

Bug bounty and community defense

To harness independent security researchers, Ether fi runs a bug bounty program that rewards people for responsibly disclosing vulnerabilities. This creates a constructive incentive for skilled researchers to probe the system and report issues rather than exploit them, adding another layer of proactive defense on top of formal audits and internal monitoring.

Understanding the risks

No honest discussion of a DeFi protocol is complete without acknowledging risk. Participation in staking and restaking involves significant risks, including the potential loss of principal, slashing penalties, and smart-contract vulnerabilities. Rewards are not guaranteed and depend on network performance. Restaking in particular can increase risk because capital may be subject to the rules and penalties of each additional system it helps secure. Ether fi's security architecture is designed to manage these risks responsibly, but users should understand that risk cannot be eliminated entirely and should make decisions accordingly. Products may also not be available in all jurisdictions.

Integrations & Ecosystem

One of Ether fi's greatest strengths is how widely its tokens are used elsewhere. The protocol has cultivated more than 400 integrations across DeFi and centralized exchanges, and this reach is a large part of why its liquid restaking tokens are so valuable. A token that can be used everywhere is far more useful than one confined to a single application.

Why integrations matter

Integrations turn a liquid restaking token from a passive receipt into an active building block. When weETH and eBTC are accepted across lending markets, fixed-yield platforms, and leverage protocols, holders gain additional ways to earn and additional flexibility in how they manage their positions. This composability compounds the value of the base staking and restaking rewards, because the same token can be productively used in several places at once.

Representative categories of use

An ecosystem, not just a product

The breadth of these integrations means Ether fi functions as an ecosystem rather than a single product. Users earn rewards when they trade, lend, or leverage across the ecosystem, and the protocol's tokens serve as connective tissue between many different applications. This network effect is self-reinforcing: the more places accept weETH, the more useful it becomes, which in turn encourages further integrations. It is a major reason Ether fi has established itself as a leading restaking platform.

For users, the takeaway is that depositing into Ether fi does not confine their capital to one venue. It equips them with a liquid, reward-bearing token that can travel across a large and growing portion of the on-chain economy, multiplying the ways their assets can work for them.

Frequently Asked Questions

What is Ether fi?

Ether fi is a decentralized, non-custodial liquid restaking protocol built on Ethereum. It lets users stake ETH, BTC, and stablecoins to earn staking and restaking rewards while keeping their assets liquid and usable across DeFi. The ecosystem also includes automated Liquid vaults, the Cash card, an Earn and membership layer, and the ETHFI governance token.

Is Ether fi the same as Etherfi?

Yes. "Etherfi" is simply the name written without the dot. Both "Ether fi" and "Etherfi" refer to the same liquid restaking protocol and ecosystem.

What is the difference between liquid staking and liquid restaking?

Liquid staking issues a tradable token that represents staked ETH and its rewards, so staked capital stays liquid. Liquid restaking goes further: the staked position is also restaked to help secure additional networks and services, layering extra rewards on top of the base staking rewards. Ether fi's weETH is a liquid restaking token, capturing both layers at once.

What is Ether fi staking?

Ether fi staking is the process of committing ETH, BTC, or stablecoins to the protocol to earn rewards. For ETH, the deposited assets run Ethereum validators and are then restaked, and the user receives a liquid token (weETH) representing the position. There is no fixed minimum and no need to run hardware.

What is weETH?

weETH is Ether fi's value-accruing liquid restaking token for ETH. Holding weETH is equivalent to holding staked and restaked ETH plus its accruing rewards. Rather than increasing in quantity, each weETH becomes redeemable for progressively more ETH over time.

What are eBTC and eUSD?

eBTC brings restaking rewards to Bitcoin while preserving BTC exposure, and eUSD is a value-accruing restaked stablecoin token for dollar-denominated yield. Together with weETH, they let Ether fi serve users who think in ETH, BTC, or dollars.

What are Ether fi Vaults?

Ether fi Vaults are automated Liquid strategy vaults. Users deposit an asset, the vault auto-balances it across high-quality DeFi protocols to optimize earnings, and rewards are auto-compounded. Depositors can withdraw or switch strategies at any time.

What is Ether fi Cash?

Ether fi Cash is a non-custodial, DeFi-native cashback card that connects an ether fi portfolio to everyday spending. It offers up to 3% cashback, 0% FX fees on EUR and USD transactions, acceptance at over 100 million locations, and support for Apple Pay and Google Pay, with no credit checks. It is issued subject to separate terms provided by its issuer.

What is Ether fi Earn?

Ether fi Earn refers to the ability to earn yield on account balances within the ecosystem, alongside membership benefits such as tiered cashback, global transfers, personal IBAN access, travel perks, and the option to borrow against assets to spend without selling them.

What is the ETHFI token?

ETHFI is the governance token of the Ether fi ecosystem. Holders can participate in governance decisions that shape the protocol's direction. It is separate from the asset tokens weETH, eBTC, and eUSD.

What is Ether fi node staking?

Node staking refers to the decentralized set of node operators that run the validators securing Ethereum on the protocol's behalf. Ether fi distributes operations across many operators for resilience and also supports solo stakers who wish to run infrastructure themselves while participating in the ecosystem.

Is Ether fi safe?

Ether fi is audited and monitored by industry-leading firms, is open source, runs a bug bounty program, and emphasizes active defense engineered to respond within seconds. That said, staking and restaking carry real risks — including potential loss of principal, slashing penalties, and smart-contract vulnerabilities — and rewards are not guaranteed. Users should understand these risks before participating.

Do I keep exposure to my assets?

Yes. Ether fi is designed so that users keep exposure to ETH, BTC, or stablecoins while earning additional rewards. Because tokens like weETH are redeemable for the underlying asset, holders continue to benefit from price movements in that asset while also earning staking and restaking rewards.

Conclusion

Ether fi represents a comprehensive reimagining of what it means to hold and use crypto assets. It begins with a simple but powerful idea — that capital committed to securing a network should not have to be idle — and builds outward from there into a full financial platform. Through liquid staking and liquid restaking, Ether fi lets users earn stacked rewards on ETH, BTC, and stablecoins while keeping their assets liquid, composable, and, above all, in their own custody.

The pieces fit together into a coherent whole. The Ether fi protocol provides a non-custodial, composable, actively defended foundation. Staking and restaking generate layered rewards, captured in value-accruing tokens like weETH, eBTC, and eUSD. A decentralized node staking layer keeps those tokens sound. Vaults automate sophisticated strategies; Cash connects on-chain value to everyday spending; and Earn and membership wrap everything in a modern account experience. The ETHFI token gives the community a voice in the protocol's future, and the entire system is anchored to Ethereum, both drawing on and contributing to its security.

What makes Ether fi stand out is not any single feature but the way its features reinforce one another. Liquid restaking makes Vaults possible; composability makes the tokens useful everywhere; self-custody makes the Cash card genuinely different from custodial alternatives; and a relentless focus on security makes the whole edifice trustworthy enough to build a financial life on. For anyone seeking to put their crypto to work without surrendering control of it, Ether fi offers one of the most complete answers available today — a place to genuinely save, grow, and spend.
