Introduction
Every time you stake tokens on a proof-of-stake network, you make an economic commitment: your capital is put at risk to help validate transactions, and in return you earn a reward. For a long time, that was the full equation. One commitment, one chain, one reward stream. **Restaking** changes that equation. Instead of your staked capital securing a single network, restaking lets that same committed capital extend its security obligations to additional protocols, services, and infrastructure layers. The capital does not double. The work it does multiplies. The concept emerged from a specific problem in Ethereum's ecosystem: new infrastructure protocols needed economic security but had no practical way to bootstrap it from scratch. **EigenLayer** introduced restaking as a solution, and the idea has since spread across the DeFi landscape. Today you can restake on Ethereum, on Solana, and increasingly on other chains, each with its own implementation and risk profile. This guide covers what restaking actually is, how it stacks yield, why the risks compound in ways that are easy to underestimate, and how the whole structure fits into the broader DeFi composability stack. If you want to see live restaking opportunities across Solana protocols before diving in, the [Lince Yield Tracker](https://yields.lince.finance/tracker/solana/category/restaking) keeps current yield data in one place.
What Restaking Actually Means
**The core idea** When you stake on a proof-of-stake chain, your tokens act as a security deposit. You are effectively saying: if I behave dishonestly, my deposit gets slashed. The network enforces that commitment through **cryptoeconomic security**, the threat of financial loss disciplines validator behavior. Restaking takes that committed deposit and extends its security obligations to additional systems. You are not depositing new capital. You are reusing the same deposit to back multiple commitments simultaneously. The tokens remain on the original chain; what changes is the scope of obligations they back. **Actively Validated Services (AVSs) explained** The systems that benefit from restaked security are called **Actively Validated Services (AVSs)**. An AVS is any protocol, network, or infrastructure layer that needs economic security to operate trustlessly. That could be a cross-chain bridge verifying messages between blockchains, an oracle network providing price data, a data availability layer storing transaction history off-chain, or a decentralized sequencer ordering transactions for a rollup. New protocols face a bootstrapping problem: they need a large pool of capital at risk to deter attacks, but they cannot easily create that pool from nothing. Restaking solves this by letting them rent security from existing stakers who are already committed. The AVS pays those stakers for taking on the additional obligation. **AVS operators** are the entities that actually run the software for each AVS. When you restake, you typically delegate to an **operator** who manages the technical work of serving multiple AVSs simultaneously. The operator earns a fee; you earn the underlying yield for providing the capital. **How restaking originated: the EigenLayer model** EigenLayer introduced this model on Ethereum to address a specific gap. Ethereum's ecosystem generates enormous validator security through ETH staking, but individual infrastructure protocols that needed economic security could not tap into it. Each new protocol had to launch its own token and convince holders to stake, a slow and expensive process. EigenLayer created a marketplace: stakers opt in to extend their security commitments to AVSs, operators manage the technical coordination, and AVSs pay for the security they consume. The model demonstrated that staked capital is underutilized when locked to a single chain's validation set, and that reusing it creates value throughout the stack. This model has since become a template. The mechanics vary by chain, but the principle carries over: staked capital, extended obligations, layered rewards, and amplified risk.
How Restaking Generates Yield
 **The yield stacking mechanism** Restaking builds yield in layers. Each layer corresponds to a different obligation the capital is fulfilling. The foundation is **base staking yield**: the reward your tokens earn for participating in consensus on the underlying chain. On Ethereum, this typically runs in the low-to-mid single digits depending on network conditions. On Solana, native staking has historically been in the 6-8% range, though rates shift with network activity and inflation schedule. On top of that sits the **AVS reward**: compensation paid by each AVS for the security services it is consuming. Every AVS sets its own reward rate based on demand for security and competition among stakers. A staker opted into multiple AVSs earns a blended rate across all of them. As a simplified illustration: if base staking yields 4% and restaking across two AVSs adds an average of 3% in combined rewards, the stacker earns approximately 7% before accounting for any further composability. The exact numbers vary by protocol, operator fees, and AVS reward schedules, but the additive structure holds. **Liquid restaking tokens (LRTs)** When you restake through a liquid restaking protocol, you receive a **liquid restaking token (LRT)** in return. An LRT is a tokenized receipt for your restaked position. Similar in concept to a [liquid staking token (LST)](/blog/yield-strategies/liquid-staking-tokens-explained), which represents staked assets on the base chain, an LRT represents restaked assets with one important difference: it inherits the **slashing** exposure of every AVS the underlying capital is committed to. The value of LRTs is that the underlying position stays liquid. You can deposit an LRT into a lending protocol as collateral, supply it to a liquidity pool, or use it in strategies that treat it as a productive asset. Examples on Ethereum include eETH from EtherFi and ezETH from Renzo, both of which represent restaked ETH positions with different AVS configurations underneath. This liquidity is what connects restaking to the broader DeFi **composability** stack, and it is also where the layered risk picture becomes most complex.
Risks That Compound With the Yield
 **Slashing risk amplification** With regular staking, your capital is subject to one set of slashing conditions: the rules of the chain you are staking on. If you behave honestly, the risk is low. If your validator misbehaves, you get slashed. With restaking, the picture changes fundamentally. Each AVS your capital is committed to carries its own independent slashing conditions. If you are opted into five AVSs, five separate sets of conditions can trigger a loss against the same capital. This is **slashing risk amplification**, the yield multiplies across AVSs, and so does the exposure. The correlation risk is particularly important. If an operator makes an error that violates one AVS's slashing rules, the capital covering that obligation is reduced. That same capital pool also backs every other AVS position. One event can impair the security guarantees across all of them simultaneously. Even if each AVS individually carries a low probability of triggering a slash, the compound probability across five or ten AVSs is meaningfully higher. AVS design, operator quality, and slashing condition triggers are all still maturing and not uniformly audited across the restaking ecosystem. For a structured view of how these risks layer across DeFi yield strategies, see [DeFi yield risks explained](/blog/risk-management/defi-yield-risks-explained). **Smart contract risk at each layer** The number of smart contract surfaces involved in a restaking position grows quickly. A typical path involves: the restaking protocol itself, each AVS's contracts, the LRT protocol's contracts, and any DeFi protocol the LRT is deposited into downstream. Each contract is an independent potential failure point. This is structurally different from regular staking, where smart contract risk is limited to the staking contract itself. Restaking stacks multiple independent attack surfaces on top of a single pool of capital. **Operational and oracle risks** Beyond slashing and smart contracts, restaking introduces operational risk through operators. You are delegating to an entity that manages technical obligations for multiple AVSs. If that operator goes offline, misconfigures their setup, or acts against an AVS's rules, the consequences flow through to your capital. LRTs also carry oracle and liquidity risk. LRT prices are typically derived from oracle feeds; if those feeds are manipulated or go stale, lending protocols that accept LRTs as collateral can behave incorrectly. If an LRT loses its peg to the underlying asset (similar to LST depeg mechanics during periods of market stress), positions built on top of it can face cascading liquidations.
Restaking Across Chains: Beyond Ethereum
**How the model extends to other chains** The EigenLayer model made restaking widely known, but the concept is chain-agnostic. Any blockchain with a validator set or staking mechanism can theoretically support an AVS layer above it, allowing restaked capital to extend economic security to additional services. Implementations differ in meaningful ways depending on each chain's base-layer design. The slashing mechanics, the operator ecosystem, the range of available AVSs, and the composability of LRTs all vary across environments. What carries over from chain to chain is the core structure: staked capital, extended obligations, layered rewards, and amplified risk. **How Solana's design changes the picture** Solana's approach to validator penalties changes the restaking risk calculus considerably. Solana's base layer does not implement slashing in the same way as Ethereum: validators who misbehave are excluded from the validator set, but their staked capital is not directly penalized at the protocol level. There is no base-layer capital destruction event. This means slashing risk in Solana restaking is defined entirely by the AVS, not the underlying chain. AVSs built on Solana set their own slashing conditions; restakers who opt into those AVSs carry AVS-defined exposure, not base-chain slashing exposure. The risk exists, but its source is different, and its structure is determined by AVS design rather than inherited from the chain's consensus rules. Solana's restaking ecosystem includes protocols such as **Fragmetric** and **Solayer**, both of which accept native SOL and LSTs as the underlying staked asset. AVS-equivalent services on Solana span data availability, cross-chain infrastructure, and application-layer security needs. For the full breakdown of Solana restaking mechanics, protocol comparisons, and yield math specific to the Solana ecosystem, see the dedicated guide: [Solana restaking explained](/blog/defi-protocols/solana-restaking-explained).
Restaking in the DeFi Composability Stack
 **Where restaking sits** Restaking does not exist in isolation. It is one node in a composability chain that can extend capital across multiple DeFi use cases simultaneously. Understanding where restaking sits in that chain matters for understanding both the yield potential and the risk concentration. A fully extended composability path looks something like this: • Stake base asset on the underlying chain and earn base staking yield • Restake through a restaking protocol and earn AVS rewards on top • Receive an LRT as a receipt for the restaked position • Deposit the LRT as collateral in a lending protocol and unlock borrowing capacity • Deploy borrowed capital in additional yield strategies At each step, yield accumulates. At each step, a new dependency and a new risk layer is added. The bottom of this stack is the base chain's consensus security. The top of the stack can involve three or four independent protocols, each with its own contracts, oracles, and liquidation logic. Most retail participants do not model the full dependency chain before entering positions at the top of the stack. The yield looks attractive; the architecture beneath it remains invisible until something breaks. **Why this matters for yield strategies** The composability stack expands what is achievable with a single unit of capital. The same tokens can simultaneously secure a base chain, service multiple AVSs, back an LRT, and collateralize a loan. That is genuine capital efficiency. It is also genuine risk concentration in a single underlying asset. Every position higher in the stack depends on the integrity of everything below it. A slashing event at the base restaking layer, an LRT depeg, or a lending protocol exploit can propagate upward and sideways across all positions in the chain simultaneously.

Common Misconceptions About Restaking
 **"Restaking is just staking twice"** This is the most common misunderstanding. Restaking does not involve depositing the same capital into two separate staking contracts. The capital is committed once; what changes is the number of security obligations it backs. Two separate staking positions would require two separate pools of capital. Restaking achieves expanded coverage from one. **"The yield is purely additive with no extra risk"** Each AVS reward layer is compensation for taking on that AVS's slashing conditions. The yield is real, and so is the additional risk. The two are inseparable. Treating AVS rewards as free amplification on top of safe base staking yield misrepresents what restakers are actually selling: the conditional right to have their capital slashed if an AVS condition is triggered. **"Restaking only exists on Ethereum"** EigenLayer brought restaking into wide awareness, and early coverage often treated restaking as synonymous with it. The concept has since spread to Solana and other ecosystems, each with native implementations and distinct mechanics. Ethereum remains the largest market by TVL, but it is far from the only environment where restaking operates. **"LRTs and LSTs are the same thing"** An LST represents staked capital on the base chain. An LRT represents restaked capital that is additionally committed to AVS obligations. The underlying mechanics of minting and redeeming are similar, but the risk profile is not. An LRT holder carries the slashing exposure of every AVS the underlying capital is committed to; an LST holder carries only base-chain staking risk.
Conclusion
Restaking is a capital efficiency mechanism that extends staked assets to secure additional networks, generating layered yield in exchange for layered risk. It originated with EigenLayer on Ethereum, has spread to Solana and beyond, and sits at the intersection of staking infrastructure, DeFi composability, and cryptoeconomic design. The compounding yield is real. So is the compounding risk. Slashing conditions multiply with each AVS. Smart contract surfaces multiply with each protocol layer. Operators, oracles, and liquidity all introduce independent failure modes that compound quietly until market stress makes them visible. Understanding the full dependency chain, from base staking through AVS obligations to LRT collateral loops, is the prerequisite for using restaking safely. The further up the composability stack a position sits, the more important it is to understand what is happening at every layer below it. [Lince Smart Vaults](https://yields.lince.finance/vaults) are designed for exactly this kind of structured multi-layer exposure: restaking and composability positions managed with automatic rebalancing and risk monitoring built in, so the yield stack works for you rather than against you.
FAQ
### What is restaking in simple terms? Restaking means using the same staked capital to provide economic security to multiple networks or services at once, rather than just one. In exchange, stakers earn additional rewards from each network they secure on top of the base staking yield they already receive. ### What is an Actively Validated Service (AVS)? An AVS is any protocol or service (such as a cross-chain bridge, decentralized oracle, or data availability layer) that needs economic security to operate trustlessly. Instead of building its own validator set from scratch, it rents security from restakers who extend their staked capital to cover its obligations. ### How is restaking different from staking? Regular staking commits capital to secure one chain and earn one reward stream. Restaking extends that committed capital to secure additional services, stacking reward layers on top. The key distinction is that slashing exposure also multiplies: one capital pool becomes subject to multiple independent slashing conditions, not just one. ### What are the main risks of restaking? The primary risks are slashing risk amplification, where each additional AVS carries its own independent slashing conditions against the same capital pool; smart contract risk across every protocol layer involved; operator risk from the entities managing AVS obligations on your behalf; and composability risk if an LRT is further deployed into lending or liquidity strategies downstream. ### What is a liquid restaking token (LRT)? An LRT is a tokenized representation of restaked capital. Holding one means you receive restaking rewards while keeping the underlying capital liquid enough to use as DeFi collateral or in vault strategies. Unlike an LST, an LRT carries the additional slashing exposure of every AVS the underlying capital is committed to. ### Does Solana restaking work the same way as Ethereum restaking? The concept is the same but the mechanics differ in an important way. Solana has no base-layer capital slashing, so slashing risk in Solana restaking is defined entirely by the AVS, not the underlying chain. Solana also has its own native restaking protocols, including Fragmetric and Solayer, which accept both native SOL and LSTs. ### Can restaking lead to a cascading failure? It can create correlated risk that cascades. If an operator is slashed by one AVS, the same underlying capital pool suffers the loss regardless of how other AVS positions are performing. Further up the composability stack, if an LRT depegs or a lending market triggers liquidations, losses can propagate across multiple DeFi positions simultaneously that all depended on the same restaked capital as their foundation.
