How LST works: yield and key risks
What LST is, where yield comes from and where the risks appear. LST is a tokenized share in staking: the network generates the yield, while the risk most often appears in the exit price, through a discount or depeg.
Liquid staking is staking through a protocol: the base asset is deposited into the protocol, and the protocol delegates it to network validators. Instead of a locked staking deposit, the user receives an LST, a token that represents the position share: how much of the base asset and accrued rewards belong to that position.
Formula: LST yield = network rewards minus the protocol fee, plus any possible incentives outside native staking.
LST (Liquid Staking Token) trades as a separate market asset, so its market price can differ from the calculated value of 1 LST.
Depeg is a deviation of the market price of LST from the calculated value of 1 LST. A common reason is the difference between a fast exit by selling on the market and redemption through the protocol, where unstaking queues or limits may prevent immediate withdrawal.
Where the risks live: the protocol layer, meaning code and governance; the network layer, meaning validators and slashing penalties; and the market layer, meaning liquidity and the exit price.
- 1 LST is not a fixed 1:1 claim. “1:1” is only a reference point: the market can trade at a premium or discount to calculated value, while protocol redemption normally requires waiting.
- APY does not lock the exit price. It shows the rate at which rewards accrue, but it does not guarantee the final result when LST is sold.
- Slashing changes the fair value. Network penalties reduce the base-asset share of the pool and can lower LST value even if the base token price has not moved.
- The protocol fee reduces yield. Final LST yield is usually close to native staking yield, or lower than it after protocol fees and losses are included.
- DeFi integrations add liquidation risk. If LST is used as collateral, a price drop can trigger liquidations and intensify the depeg.
If LST yield is noticeably higher than the native staking yield of the network, it is usually separate DeFi incentives, such as payouts or subsidies: liquidity incentives or lending-market yield, where lending means credit markets. That bonus is separate from staking rewards and can quickly shrink or end according to the program rules.
What liquid staking and LST mean
You stake an asset through a protocol and receive a token that lives as a separate market asset.
Liquid staking is a model where the base asset is deposited into a smart contract or protocol pool, and the protocol stakes it in the network by delegating to validators, often across several operators to reduce concentration risk.
In return, the protocol issues an LST (Liquid Staking Token), a tokenized representation of the stake. The calculated value of 1 LST shows how much base asset and accrued rewards correspond to 1 LST under the protocol mechanics, but the market price can be above or below that value.
Sometimes this class of tokens is called LSD (Liquid Staking Derivatives): this is a common name for liquid-staking tokens. In this article, the focus is LST, the token that represents your staked position and the rewards that accrue to it.
The key practical point: the model creates two exit paths — sell LST on the market immediately at the current market price, or redeem it through the protocol, usually with waiting time, queues or limits, to receive the base asset at the calculated value of 1 LST.
How the LST model works
The protocol accepts a deposit, delegates it to validators and issues LST, which reflects the position share: how much base asset and how many rewards correspond to 1 LST.
- Deposit → the base asset enters the liquid-staking protocol smart contract or pool, which tracks shares and LST issuance through balances or an exchange rate.
- Staking → the protocol delegates funds to network validators, where a validator is a node that confirms blocks and receives rewards.
- LST issuance → the holder receives a token that records the holder’s share in the total staked pool.
- Rewards → the network accrues staking rewards, and the protocol reflects them through rebasing or through growth of the LST exchange rate, after subtracting the protocol fee.
- Circulation → LST trades on the market and can be used in DeFi as collateral in lending markets, where lending means credit markets, or as an asset in liquidity pools.
Reward accounting is usually implemented as rebasing where the token balance increases, or as growth of the LST “rate” against the base asset, where the balance stays the same but the LST-to-base-asset ratio grows. In both cases, the amount of base asset corresponding to the LST position increases; only the way it is displayed differs.
Where real yield ends and illusion begins
The base layer is network rewards; anything above that base is an external mechanism with a separate risk.
1) Base source: network rewards
In PoS networks (Proof of Stake networks, where validators confirm blocks by placing stake and accepting slashing risk), validators earn rewards for operating the network. The liquid-staking protocol passes those rewards to LST holders after subtracting its own fee. This is the base component of LST yield: network rewards minus protocol or validator fees and any possible slashing penalties.
2) Additional yield: external incentives
Additional yield can come from external sources: liquidity incentives on DEXs, meaning decentralized exchanges; yield on lending markets, meaning credit markets; bonus programs and similar mechanisms. This yield is not a staking reward from the network: it depends on program rules, incentive size or rates, borrowing demand and liquidity, and it can change or disappear quickly.
A common expectation error: adding “staking APY” and a “DeFi premium” into one “sustainable percentage”. The premium can end, while protocol and market risks remain. If the premium disappears, the risk does not disappear with it.
3) Yield versus LST price
Reward accrual and the market price of LST are different things. The final result when exiting through sale depends not only on APY, but also on the exit price: premium or discount to the calculated value of 1 LST, meaning the base-asset share plus rewards, as well as spread and slippage at the moment of trade. In practice, two questions matter: which exit path is chosen — market sale or protocol redemption with waiting time and limits — and what liquidity looks like in terms of depth and spreads at the moment of exit.
Why depeg happens and why it is dangerous
Depeg is the difference between the market price of LST and the calculated value of 1 LST, meaning the base-asset share plus accrued rewards.
Depeg is when 1 LST trades on the market below and sometimes above its calculated value. Depeg usually appears because of exit conditions and liquidity: LST is not a promise of instant 1:1 conversion, but a share token, and the market price depends on exit speed, market depth and protocol risks such as vulnerabilities, upgrades, admin powers and validator operators.
Base mechanic: if many holders need a fast exit while protocol redemption is slow because of waiting time, queues or limits, holders sell LST on the market at a discount to the calculated value of 1 LST. That is how depeg appears.
Typical depeg triggers
- Liquidity stress → sharp market moves, deleveraging and a rising demand for cash or stablecoins.
- Exit restrictions → unstaking delays, queues, withdrawal limits and network or protocol-specific mechanics.
- Thin market → low liquidity in pools, where large sales worsen execution price and widen the spread.
- Protocol risk → reports of a vulnerability or incident, a disputed upgrade, governance risk or validator-operator risk.
- Leverage in DeFi → LST used as collateral can create forced liquidation flow and intensify the discount.
Depeg makes liquidity conditional: a fast exit is possible through a sale, but the exit price can differ materially from the calculated value of 1 LST because of discount, spread and slippage. In practice, depeg is the discount the market charges for urgency and risk.
Risk map: where the model breaks
It is useful to split LST risks into four layers: network, protocol, market and DeFi integrations.
Network layer: validators and slashing
Slashing, meaning a network penalty, reduces the amount of base asset in the pool if validators break the rules.
- Source: downtime, configuration errors and violations of consensus rules.
- Manifestation: the base asset in the pool decreases, so the calculated value of 1 LST falls, meaning the share in stake plus rewards falls.
- Meaning: the market changes price, but slashing reduces the base, the base asset itself, so the calculated value of 1 LST falls.
Protocol layer: smart contract and governance
Governance is the update process and the permission set that determine security and exit parameters such as pauses, limits and upgrades.
- Source: code vulnerability, upgrade error or compromise of admin keys.
- Manifestation: frozen or lost funds, share-accounting failure through LST balances or exchange rate, redemption pause or changed redemption rules and limits.
- Meaning: the protocol adds its own failure point on top of network risk, even if the network itself works normally.
Market layer: liquidity and depeg
LST is a market asset: the exit price depends on market depth and spreads, not only on accrued rewards.
- Source: demand and supply imbalance, thin DEX pools and stressed demand for a fast exit.
- Manifestation: discount to calculated value, wider spreads and severe slippage on large sales.
- Meaning: rewards accrue inside the protocol, but the result is fixed by the market price at the moment of exit.
Integration layer: DeFi around LST
Collateral , price source and liquidations can intensify market deviations.
- Source: liquidations, oracle failures and integration mistakes.
- Manifestation: price drop leads to liquidations, liquidations lead to forced LST sales, and forced sales widen depeg during stress periods.
- Meaning: LST starts living inside collateral and liquidation mechanics, where forced sales can widen the discount.
The layers are connected: falling liquidity worsens price, a worse price triggers liquidations, and liquidations add forced sales. For LST, the typical cascade is discount → liquidations → sales → deeper discount, not one isolated failure.

Common misconceptions about LST
Almost all mistakes come from ignoring the exit price and protocol risk.
- “LST is always 1:1.” “1:1” is a calculated reference point against the calculated value of 1 LST, meaning base-asset share plus rewards; on the market there can be a premium or a discount.
- “Yield is guaranteed because it accrues.” Rewards increase calculated value, but the outcome depends on the sale price or the redemption terms, including waiting time and redemption or withdrawal limits.
- “Liquidity means no risk.” Liquidity is the ability to trade; risk appears in the spread, slippage and execution price.
- “Extra APY is equivalent to staking.” An external premium is a separate incentive, subsidy or farming program where payouts or incentive rates can quickly fall or end.
LST connects staking and the market: accruals are generated by the network, while the exit result is determined by discount, spread, slippage and redemption availability. APY is not the final result if the exit price moves into a meaningful discount or if redemption is not immediately available.
Implementation variants: how LST providers differ
The main differences are usually operators, governance, fees and exit rules.
Liquid-staking providers differ in their governance and exit model: how they select and control validator operators, whether risk is concentrated or diversified, and who can change protocol parameters such as upgrades, pauses, limits and fees.
Fees also matter separately: how much of the rewards are retained, how redemption works, how long unstaking takes before the base asset is received at calculated value, whether there are queues and daily limits, and whether restrictions can appear in stress periods.
In practice, this determines how much the exit price can deteriorate: discount to calculated value, spread and slippage at the moment of sale.
- Validator operators → how distributed the risk is, from concentration among a few operators to broad diversification.
- Governance → who can change parameters such as upgrades, pauses, limits and fees, and how transparent the process is.
- Fees → how many rewards are retained and how that affects the holder’s net yield.
- Exit → whether there is a queue, daily limits, delays and redemption restrictions during stress periods.
- Liquidity → how resilient spreads and depth are, in DEX pools or CEX markets, during sharp moves.
LST FAQ: exit, depeg, liquidity and fees
Short clarifications that usually come up after the basic LST model is understood.
What matters more: rebasing or LST “rate growth”?
These are two ways to show the same thing: how the protocol accounts for staking rewards. With rebasing , the amount of LST in the wallet grows. With “rate growth”, the LST balance does not change, but the exchange rate grows: how much base asset corresponds to 1 LST. It is important to know where the yield is displayed — in token quantity or in exchange rate — and what exactly counts as the calculated value of 1 LST: how much base asset and accrued rewards correspond to 1 LST under the protocol mechanics.
How does the protocol fee affect yield?
The fee is usually withheld from staking rewards, so LST yield is most often lower than, or close to, the native staking yield of the network after the protocol fee is retained. This is not a one-time payment: the effect is continuous, because the distributed share of rewards is reduced in every accrual period.
What determines LST liquidity and market spreads?
Primarily where the LST trades and how much liquidity is there: depth in DEX pools or volume on CEX markets, participant activity, concentration among large holders, because one large trade moves the price more, and arbitrage activity. During stress periods, liquidity often worsens because of one-sided trade flow and forced sales, for example during liquidations, while spreads widen.
How does a depeg usually close if it has appeared?
The discount narrows when seller pressure falls, market depth returns and arbitrage works again. If protocol redemption is available and timing or limits allow it, the typical arbitrage logic is: buy LST at a discount, wait for redemption, receive the base asset. The speed of closure depends on exit conditions, including queue, limits and unstaking period, and on the state of the market.
What matters more for risk: exit terms or a “beautiful APY”?
APY describes reward accrual, but real risk is often decided by exit terms: redemption queues or limits, secondary-market liquidity and possible discount during stress scenarios. APY is the accrual rate, while the exit price is discount, spread, slippage and redemption availability: it is possible to have high APY and a poor exit price at the moment of sale.
What LST risks are different from holding the base asset?
Beyond the market risk of the base asset, LST adds protocol risk such as smart contracts, admin powers, upgrades and validator operators, LST price risk such as liquidity, spreads and depeg, and integration risk if LST is used as collateral or in DeFi strategies.
Final takeaway: what LST gives in practice
LST makes a stake tradable through the market, but it moves part of the result into the exit price and protocol risk.
Liquid staking turns a native stake with an exit wait, such as unstaking or a queue, into a market asset: instead of a position that cannot be closed instantly, there is a token whose calculated value reflects the base-asset share and accrued rewards per 1 LST.
But together with convenience, two practical risks are added: protocol risk meaning code, governance and operators, and exit price risk meaning discount to the calculated value of 1 LST, spread and slippage in stress scenarios.
Key formula: LST = staking + market + protocol.
Rewards are accrued by the network, while the final result depends on the exit path: when selling, the market price of LST is fixed; when redeeming through the protocol, the user receives the base asset at the calculated value of 1 LST, but under protocol conditions such as waiting time, queues and limits.
