Can I Keep a SparkLend Loan Open Without a Fixed Repayment Date?

SparkLend loans have no fixed repayment term while the position remains within its borrowing conditions. Interest continues accruing while the loan stays open. That open-ended term does not remove the liquidation threshold. Collateral prices, accrued interest, and applicable market changes can make a previously healthy position liquidatable. A market wind-down can also change those conditions, so the absence of a scheduled maturity does not preserve access indefinitely.

Where Does a Public Allocator Reallocation Fee Come From?

A Public Allocator reallocation fee comes from your wallet on top of network gas when an isolated borrow sources liquidity from other Morpho markets. Vault curators set the fee, and the Borrow dialog shows an acknowledgement before confirmation. The dialog separately shows the projected Borrowed balance and Health Factor. The fee describes a transaction cost, while the ratio describes collateral coverage; additional liquidity remains subject to curator flow caps.

Does a peg-protection Halt Mean My Health Factor Is Below 1?

A peg-protection halt responds to a collateral asset’s price deviation, which differs from the health factor’s liquidation trigger. SparkLend’s killswitch compares selected pegged collateral with its underlying reference. Breaching that asset’s configured deviation threshold halts new borrowing. A blocked borrow therefore does not, by itself, establish that your position has crossed below 1 or that a liquidation has executed. The position’s health factor and debt balance remain separate observations.

How Can Received USDC and Recorded USDS Debt Describe the Same Borrow?

A periphery route can deliver USDC from a USDS-denominated position without changing the debt denomination. That path sources USDS and uses Sky’s mainnet LitePSM wrapper for a 1:1 conversion. Its availability depends on the active frontend and periphery integration; receiving USDC alone does not establish this route. The recorded debt asset, plus accrued interest, determines repayment requirements and the debt balance that matters to the position.

Is a Pending Spark Savings Withdrawal a Borrower Liquidation?

A pending Savings Liquidity Intents request records an unfulfilled redemption, not a borrower liquidation. For Spark Savings V2, direct redemption needs sufficient idle liquidity. The Spark ALM Planner prepares liquidity before an authorized relayer fulfills the request. That pending status describes access to vault assets, whereas a borrower liquidation covers debt through collateral transfer. An estimated withdrawal time does not establish that redemption has completed.

Sparkfi liquidations become possible when a borrowing position’s health factor falls below 1

Sparkfi liquidations become possible below a health factor of 1, allowing liquidators to repay debt and receive collateral. The ratio compares collateral value, adjusted by liquidation parameters, with debt value. SparkLend assesses pooled positions, while Morpho-powered Isolated Markets assess individual collateral-and-loan pairs. A first check should identify the market, the current ratio, and the effect that an additional borrow would have. Crossing the threshold creates liquidation eligibility; a completed liquidation then changes the recorded debt and collateral balances. Interest and prices can alter either position’s health factor; governance can also change SparkLend’s risk parameters. Borrow previews describe a proposed change, while the updated position after executed transactions shows what the account now owes.

From a Falling Health Factor to Collateral Loss

Collateral price declines or rising debt value can move an existing position from adequate coverage into liquidation eligibility. Accrued borrowing interest can increase the debt even without a new borrow. Once the health factor falls below 1, a liquidator can cover eligible debt and receive collateral under the market’s liquidation rules. The crossing alone does not confirm that somebody has executed a liquidation.

An executed liquidation changes the position’s balances: covered debt decreases, and the corresponding collateral leaves the borrower. Any remaining debt still requires collateral coverage. Supplying additional eligible collateral where the market permits it or repaying debt can improve a position before liquidation. Afterward, those actions apply to the remaining position; a repayment does not itself return collateral that a completed liquidation transferred.

Pooled and Isolated Liquidation Exposure

SparkLend combines eligible collateral within a pooled borrowing position, so its health factor reflects the position’s combined collateral support and can fall when one asset loses value, even if the debt amount has not changed. SparkLend uses an Aave v3-derived money market architecture, with per-asset risk parameters. The market’s global controls and reserve liquidity operate alongside the borrower’s individual liquidation condition.

Isolated Markets define each Morpho lending market through one collateral token and one loan token. Its oracle and liquidation loan-to-value ratio (LLTV) govern the position within that pair. A loan-asset shortfall stays with suppliers in the affected market. That isolation does not make its collateral immune to price declines. The selected borrowing product’s own liquidation rules determine how much debt a call can repay.

How Is the Health Factor Calculated?

Health factor equals liquidation-adjusted collateral value divided by debt value, using compatible valuation units for both sides. SparkLend weights collateral value by the applicable liquidation thresholds when calculating its health factor. Eligible collateral assets contribute to the pooled position’s overall coverage. A savings-vault balance alone does not establish a borrowing position’s health factor.

An Isolated Market’s health factor uses that market’s collateral valuation and LLTV. The loan asset defines the debt that the collateral must cover.

A health factor above 1 means the position remains above its liquidation trigger at that valuation. At exactly 1, the standard trigger requiring a value below 1 has not been met. A narrow margin leaves less room for changes in collateral prices or debt value.

Current balances matter as much as the threshold. Accrued interest changes the denominator, while collateral prices affect the numerator. An old wallet balance, an earlier borrow quote, or a previously recorded ratio cannot establish the position’s present liquidation status. Read the current position before interpreting another borrow’s projected effect.

Borrowing Limits and Liquidation Thresholds

Available borrowing capacity and liquidation eligibility answer different questions about a position. SparkLend’s loan-to-value (LTV) setting controls borrowing power; its liquidation threshold determines the collateral weight in the health factor. SparkLend borrowing also depends on supply and borrow caps, collateral settings, and available reserve liquidity. Those constraints can limit a borrow even when the health factor remains above 1. Conversely, available market liquidity does not create additional collateral coverage for an already exposed position.

Isolated Markets show their LLTV as Max LTV, and that value forms part of the market’s fixed definition. Borrow availability accounts for collateral capacity and reachable liquidity. The Public Allocator can bring liquidity from other Morpho markets within curator-defined flow caps. It supplies the loan asset; it does not increase the borrower’s collateral value or change the market’s LLTV.

A First Check Before Signing a Borrow

You can inspect your current borrowing position and preview an additional borrow without signing a transaction. The account’s existing collateral and debt establish the starting state. The borrow dialog then shows the projected borrowing balance and health factor for the selected amount. Closing the dialog before signing leaves that proposed borrow unexecuted.

A current ratio above 1 leaves room to assess an additional borrow against collateral capacity and market liquidity. If the preview preserves the intended margin, the transaction remains only a proposed change until the required actions finish.

A position below 1 already meets the liquidation trigger. Additional debt cannot restore collateral coverage; repayment can increase the ratio, as can supplying additional eligible collateral where the market permits new supplies and collateral use.

Match the displayed position to the market that holds the debt.
Stop if the proposed borrow exceeds collateral capacity or available liquidity.
Reduce the amount if its projected ratio leaves insufficient margin.
Close the dialog if the debt asset or proposed change is unclear.
Read the updated debt and health factor after the actions complete.

The updated position shows the borrowing outcome through its recorded debt and health factor. A signature alone does not establish that change. If liquidation has already transferred collateral, subsequent adjustments concern the surviving position; they do not reverse that transfer.

What Changes When SparkLend’s Health Factor Reaches 0.95?

SparkLend allows a larger maximum debt repayment per liquidation call when the health factor reaches 0.95. Below 1 but above 0.95, a liquidation can cover up to 50% of the borrower’s debt in the selected debt asset. At a health factor at or below 0.95, SparkLend permits up to 100% of the borrower’s debt in the selected debt asset to be covered in one liquidation call.

The close factor limits debt that a call can cover; it does not state the percentage of collateral that disappears. Collateral transferred depends on the covered debt, oracle prices, and the collateral asset’s liquidation bonus. A maximum allowance also does not require every liquidation to use that full allowance. These thresholds describe SparkLend’s regular liquidation mechanics. Morpho-powered Isolated Markets allow liquidators to repay part or all of a position’s debt once its health factor is below 1, without SparkLend’s 0.95 cutoff.

Liquidation Bonuses and Network Costs

The liquidation bonus determines how much collateral a liquidator receives relative to the debt covered at the applicable prices. For the borrower, that additional collateral transfer is the liquidation penalty. SparkLend’s penalty depends on the collateral asset and applicable E-Mode settings; Isolated Markets use a market-specific penalty. One percentage cannot describe every position. Read the penalty alongside the amount of debt that a liquidation covers.

Network fees pay for onchain transactions and vary with chain conditions and transaction complexity. They are separate from collateral lost through the liquidation penalty. Adding collateral or repaying debt also requires onchain actions. The network fee itself does not repay debt or add collateral to the position.

Interest and Prices Between Checks

Borrowing interest can lower the health factor over time by increasing debt relative to collateral coverage. SparkLend’s variable rates respond continuously to supply and demand. Transparent rates act as fixed rates in the short term but can change through Sky Governance. Isolated Markets derive rates from their utilization-based interest rate model. A previous healthy reading therefore describes one valuation and debt balance; it does not establish how long that margin will last under changing prices and rates.

Oracle Inputs Behind the Displayed Ratio

SparkLend uses RedStone, Chainlink, and Chronicle prices through a three-oracle aggregation mechanism. With three valid, non-stale readings, it uses the median. With two valid readings, it uses their average, and a single-feed fallback exists. The available valid inputs therefore affect how the protocol derives the valuation behind the displayed health factor.

Each Morpho-powered Isolated Market uses the oracle specified at market creation. That oracle is immutable alongside the collateral token, loan token, LLTV, and interest rate model. Fixed market parameters do not fix future prices or rates, because the oracle still supplies collateral valuations and the interest rate model continues responding to utilization within the rules that the market established at creation. The market details’ Oracle panel shows that feed and explains the collateral-to-loan valuation.

Governance Changes and the Gnosis Wind-Down

Governance changes can alter a SparkLend position’s borrowing conditions separately from ordinary price movements. Sky Governance fully deprecated the Gnosis Chain deployment in September 2026. Its markets remain frozen to new supplies, borrowing, and new collateral use, while suppliers can still withdraw their assets. SparkLend’s active deployment is on Ethereum; the Gnosis change did not deprecate other Spark products on that chain.

The September 10, 2026 wind-down set Gnosis collateral loan-to-value ratios to 0% and liquidation thresholds to 0.01%. Remaining borrow positions became liquidatable with a full close factor. That terminal market change differs from monitoring a live Ethereum position under regular parameters. A health factor recorded before deprecation cannot establish present borrowing access, and ordinary margin management does not reopen a frozen market.
