Suilend gives users access to decentralized lending and collateralized borrowing on the Sui blockchain. Depositors can supply assets and receive variable interest, while borrowers can obtain liquidity without immediately selling their crypto holdings.
The platform makes these operations accessible, but a simple interface does not remove the financial risks behind a loan. Many losses occur not because users misunderstand blockchain technology, but because they overlook basic position-management principles.
The most common mistakes include borrowing too close to the maximum limit, ignoring the collateral ratio, using a high loan-to-value ratio, and failing to monitor the position after receiving a loan. Users may also underestimate variable interest rates, choose unsuitable collateral, or assume that the Health Factor will remain stable.
A Suilend loan is a dynamic position. The market value of collateral changes, the borrowed asset can appreciate, and interest continually increases the debt. A position that initially appears safe can move toward liquidation without the borrower making another transaction.
Responsible use therefore requires more than depositing collateral and taking a loan. Users must understand how Suilend evaluates account health, maintain a meaningful safety buffer, and have a clear plan for repaying debt or adding collateral when conditions deteriorate.
Mistake 1: Treating Maximum Borrowing Power as a Recommended Amount
Suilend calculates how much a user can borrow against eligible collateral. This figure represents the protocol’s maximum permitted capacity under the current market parameters.
It is not a recommendation.
Borrowing close to the maximum creates a fragile position. Even a moderate movement in collateral or debt prices can significantly reduce account health.
Suppose a user deposits collateral worth $10,000 and borrows almost the full amount permitted by the protocol. If the collateral falls by 10%, the debt now represents a much larger share of the position. Accumulated interest can reduce the remaining safety margin further.
A user who instead borrows a smaller amount has more room to absorb volatility before liquidation becomes possible.
How to Avoid This Mistake
Use only a conservative portion of the available borrowing capacity. The appropriate amount depends on:
Collateral volatility
Borrowed asset volatility
Correlation between collateral and debt
Current Borrow APR
Expected loan duration
Personal ability to monitor the position
Availability of funds for repayment
A position should remain manageable after an unfavorable market movement, not only under the conditions visible when the loan is opened.
Mistake 2: Ignoring the Collateral Ratio
The collateral ratio describes the relationship between the value of the assets securing a loan and the value of the outstanding debt.
In an overcollateralized lending system, collateral must be worth more than the borrowed assets. This excess value protects suppliers if the borrower’s position becomes unhealthy.
For example, a user with $10,000 in collateral and $4,000 in debt has more protection than a user with the same collateral and $7,000 in debt.
The collateral ratio changes continuously because market prices and debt balances do not remain fixed.
It can deteriorate when:
Collateral falls in price
The borrowed asset appreciates
Interest increases the debt
The user removes part of the collateral
Several adverse events happen simultaneously
Users often focus only on the initial ratio. What matters is whether the collateral continues to provide sufficient protection throughout the loan.
How to Avoid This Mistake
Review the collateral-to-debt relationship regularly. Do not assume that a position remains safe because no additional funds have been borrowed.
Maintain enough excess collateral to withstand meaningful volatility and growing interest. When the buffer becomes smaller, repay debt or add suitable collateral before the account reaches its liquidation threshold.
Mistake 3: Using an Excessively High LTV
Loan-to-value, or LTV, compares the market value of outstanding debt with the value of the collateral.
A simplified calculation is:
LTV = Debt Value ÷ Collateral Value
If a user has $4,000 in debt and $10,000 in collateral, the position has an approximate LTV of 40%.
If the collateral falls to $8,000 while the debt remains around $4,000, the LTV rises to 50%. The borrower has not taken another loan, but the position has become more leveraged.
A high LTV provides less room for adverse price movements. The closer it is to the liquidation boundary, the less time the borrower may have to react.
High LTV can appear attractive because it releases more liquidity from the same amount of collateral. However, this greater capital efficiency comes directly from accepting greater liquidation risk.
How to Avoid This Mistake
Select a personal maximum LTV that remains well below the protocol limit.
The appropriate level depends on the asset. Volatile collateral requires a larger safety margin than an asset with relatively stable pricing and deep liquidity.
Stress-test the position before borrowing. Consider what the LTV would become if the collateral declined by 20%, 30%, or more. Also examine the effect of the borrowed asset rising at the same time.
Mistake 4: Confusing LTV With the Liquidation Threshold
LTV and the liquidation threshold are connected but are not identical.
LTV describes the current relationship between debt and collateral. The liquidation threshold is the point at which Suilend permits third-party liquidators to reduce an unhealthy position.
Different collateral assets can have different liquidation parameters. When several assets are used, Suilend calculates a weighted threshold based on the composition of the deposited collateral.
A borrower may therefore have an LTV below 100% and still be close to liquidation. The protocol does not wait until debt equals the full market value of collateral.
This is necessary because collateral prices can move quickly and liquidators need enough remaining value to repay debt and receive an incentive.
How to Avoid This Mistake
Review the liquidation parameters of each collateral asset rather than relying on a general assumption about overcollateralization.
Pay attention to the Health Bar and the distance to the Liquidation Threshold. Do not interpret unused market value as fully available borrowing capacity.
Mistake 5: Ignoring the Health Factor
The Health Factor summarizes whether the risk-adjusted value of collateral remains sufficient to support the debt.
Suilend calculates the position using current supply values, borrow balances, oracle prices, and the weighted liquidation parameters of deposited assets.
A healthy position has a meaningful buffer. A weakening Health Factor indicates that the account is moving closer to liquidation.
Users sometimes check this indicator only when taking the original loan. This is a major mistake because the Health Factor changes with market prices and accrued interest.
When the Health Bar reaches the Liquidation Threshold, third-party liquidators can repay part of the debt by selling collateral. They also receive an incentive, creating an additional cost for the borrower.
How to Avoid This Mistake
Establish a personal warning level well before the protocol’s liquidation boundary.
When the Health Factor reaches that level:
Stop increasing leverage
Repay part of the loan
Add eligible collateral
Reduce exposure in related strategies
Close the position when necessary
The indicator should be treated as an early-warning system, not as something to examine only when liquidation is already close.
Mistake 6: Monitoring Only the Collateral Price
Borrowers often watch the value of their collateral while ignoring changes in the borrowed asset.
Both sides affect position health.
If a user deposits SUI and borrows a stablecoin, a decline in SUI increases liquidation risk. If a user deposits a stablecoin and borrows a volatile asset, the position can weaken when the borrowed token appreciates.
The most dangerous situation occurs when collateral falls while the borrowed asset rises. The collateral provides less protection at the same time that the debt becomes more valuable.
How to Avoid This Mistake
Monitor:
Collateral market value
Borrowed asset market value
Total debt
Accumulated interest
Health Factor
Current Borrow APR
Treat the loan as a relationship between changing assets rather than as a static amount denominated at the time of borrowing.
Mistake 7: Forgetting That Interest Increases the Debt
A Suilend borrower must repay the original loan plus accumulated interest.
Interest accrues over time, so the debt balance can continue growing even when the user takes no further action. This gradually raises LTV and reduces the Health Factor.
The effect may appear small over a short period, but it becomes increasingly important for long-term loans or leveraged strategies.
A position can eventually approach liquidation even if collateral and debt prices remain relatively stable.
How to Avoid This Mistake
Include future interest in the borrowing plan.
Estimate the cost of maintaining the loan for the expected period and review the outstanding balance regularly. Partial repayments can reduce both current risk and the amount of interest accumulated in the future.
Do not base a long-term strategy only on the initial debt amount.
Mistake 8: Assuming the Borrow APR Is Fixed
Suilend uses variable interest rates that respond to reserve utilization.
Utilization measures how much of the supplied asset has been borrowed. When demand increases and available liquidity becomes scarce, the Borrow APR rises.
A loan opened at a relatively low rate can therefore become substantially more expensive.
A rising Borrow APR creates two problems:
It reduces the profitability of any strategy funded with the loan.
It causes the debt to grow faster, weakening the Health Factor.
Rates can move particularly quickly in smaller reserves and isolated markets, where one large borrow or withdrawal has a significant effect on utilization.
How to Avoid This Mistake
Before borrowing, examine:
Current Borrow APR
Reserve utilization
Available liquidity
Size of the lending pool
Interest-rate curve
Market classification
Stress-test the loan at a higher rate. A strategy that remains viable only while borrowing stays inexpensive is not resilient.
Mistake 9: Failing to Monitor the Position
An active Suilend loan cannot safely be opened and forgotten.
Crypto markets operate continuously. Collateral can decline, debt assets can rise, borrowing rates can change, and reserve liquidity can deteriorate at any time.
Users who do not monitor their positions may discover the problem only after liquidation has already occurred.
Monitoring becomes especially important when:
Collateral is highly volatile
LTV is elevated
The borrowed asset is volatile
Reserve utilization is high
The loan is held for a long period
Leverage or looping is used
The position depends on temporary rewards
How to Avoid This Mistake
Create a regular monitoring routine.
Review the position more frequently during market volatility and track:
Health Factor or Health Bar
Distance to liquidation
Current LTV
Collateral value
Borrow balance
Borrow APR
Utilization
Available repayment liquidity
Decide in advance which action will be taken at specific risk levels. A predefined plan reduces the chance of making emotional decisions during a market decline.
Mistake 10: Waiting Until the Last Moment to Act
Users sometimes notice that a position is weakening but delay repayment because they expect the market to recover.
This creates substantial operational risk.
Even after deciding to act, a borrower may need to:
Transfer funds to the wallet
Acquire the borrowed asset
Complete a swap
Pay network fees
Submit a repayment
Wait for transaction confirmation
During fast market movements, liquidation may occur before all these steps are complete.
How to Avoid This Mistake
Act while the position still has a comfortable buffer.
Keep part of the borrowed asset or another liquid repayment asset available. Maintain enough SUI for transaction fees and avoid placing every token inside the collateral position.
Early repayment may reduce potential upside, but it preserves control over which assets are sold and when.
Mistake 11: Using Unsuitable Collateral
Not all collateral assets provide the same level of safety.
A token may be accepted by Suilend while still carrying significant volatility, liquidity, oracle, bridge, issuer, or redemption risks.
A high-risk asset may lose value quickly or become difficult to liquidate during market stress. Suilend may apply more conservative parameters, but the borrower remains exposed to the token’s underlying weaknesses.
Liquid staking tokens and stablecoins have specific risks as well. An LST can deviate from the value of its underlying asset, while a stablecoin can lose its intended peg.
How to Avoid This Mistake
Before borrowing against an asset, evaluate:
Price volatility
External market liquidity
Oracle support
Redemption mechanism
Smart-contract dependencies
Main or isolated market status
Deposit and borrowing caps
Historical behavior during stress
Use collateral you understand and would be willing to hold even without borrowing against it.
Mistake 12: Underestimating Isolated Assets and Markets
Suilend uses isolation to contain the risks of newer, more volatile, or less liquid assets.
When borrowing an isolated asset, the collateral supporting that position may be restricted and cannot necessarily support other loans. The isolated token may also be required to remain the only borrowed asset associated with the account.
Isolation protects the broader protocol, but it does not make the individual position safe.
Isolated markets can experience:
Sharp changes in Borrow APR
Limited withdrawal liquidity
More volatile collateral values
Conservative borrow limits
Greater oracle uncertainty
Potential loss socialization
How to Avoid This Mistake
Understand the isolation rules before depositing or borrowing.
Use a separate, limited allocation for higher-risk markets and monitor them more actively. Beginners should generally learn the protocol through deeper main-market reserves before using isolated assets.
Mistake 13: Chasing Yield With Borrowed Capital
Some users borrow assets and deploy them into another strategy because the displayed return appears higher than the Borrow APR.
For example, a strategy may offer a 12% annualized return while the loan costs 7%. The apparent spread is 5%.
This calculation can be misleading.
The strategy return may include temporary incentives, while the borrowing cost is variable. Fees, slippage, reward-token depreciation, and liquidation risk can further reduce the actual result.
If the Borrow APR rises to 12% or the strategy yield falls, the expected profit disappears while the debt remains.
How to Avoid This Mistake
Calculate net yield rather than comparing headline rates.
Subtract:
Borrow interest
Swap fees
Redemption fees
Slippage
Transaction costs
Management or strategy costs
Potential reward-token depreciation
Also consider whether the expected return adequately compensates for liquidation and smart-contract risk.
Mistake 14: Using Excessive Leverage or Looping
Looping involves depositing collateral, borrowing against it, acquiring more collateral, and repeating the process.
This increases gross exposure and can amplify yield. It also increases debt and reduces the safety buffer.
Users may focus on the larger staking or lending position while ignoring that much of it is financed with borrowed capital.
A small unfavorable change in rates or asset values can have a much greater effect on a leveraged position than on an unleveraged deposit.
How to Avoid This Mistake
Start with no leverage or a low level of leverage.
Track net position value, calculated as the value of deposits minus outstanding borrows. Do not judge success only by the size of the supplied balance.
Understand the complete process required to unwind the loop and verify that sufficient liquidity exists for the exit.
Mistake 15: Assuming a One-Click Strategy Requires No Monitoring
Suilend Strategies can manage minting, borrowing, looping, unstaking, and other actions in the background.
This simplifies execution but does not remove risk.
A preset strategy can still face:
Liquidation
Accumulated borrowing interest
Changing rewards
Smart-contract failures
Oracle dependencies
Liquidity constraints
Difficult exit conditions
A user may not see every underlying transaction, but the financial obligations remain real.
How to Avoid This Mistake
Review the strategy’s collateral, debt, leverage, yield sources, fees, and withdrawal mechanics before depositing.
Monitor Net Value and updated APR, but also understand how the strategy would perform if rewards declined or Borrow APR increased.
Mistake 16: Keeping No Emergency Liquidity
Users sometimes deposit all available assets as collateral to maximize borrowing capacity or yield.
This leaves no liquid funds for:
Partial repayment
Additional collateral
Network fees
Personal expenses
Unexpected market events
A user may have substantial value inside Suilend but still be unable to protect the position quickly.
How to Avoid This Mistake
Maintain an emergency reserve outside active lending and borrowing positions.
Keep enough SUI for several transactions and enough liquid assets to reduce debt without depending entirely on withdrawing collateral from the same position.
Mistake 17: Assuming Deposited Collateral Can Always Be Withdrawn
Collateral supporting an active loan cannot be freely removed if the withdrawal would make the position unsafe.
Even deposits not supporting debt depend on available reserve liquidity. When utilization reaches 100%, all supplied assets are effectively borrowed and withdrawals may temporarily fail.
A user may therefore be unable to access the expected funds at the moment they are most needed.
How to Avoid This Mistake
Review available liquidity and utilization before depositing.
Do not treat Suilend collateral as equivalent to a wallet balance. Maintain separate funds for short-term needs and understand how much collateral can be removed without weakening the Health Factor.
Mistake 18: Having No Repayment or Exit Plan
A borrower may know why the loan is being taken but not how it will be repaid.
Without a repayment source, the user may keep the debt open indefinitely while interest accumulates. Eventually, the position may require selling collateral, possibly under unfavorable conditions.
Complex strategies can be even harder to exit because users may need to reverse swaps, repay loans, redeem liquid staking tokens, and withdraw several assets.
How to Avoid This Mistake
Before borrowing, define:
The purpose of the loan
Expected duration
Repayment asset
Source of repayment funds
Maximum acceptable Borrow APR
Personal minimum Health Factor
Conditions that will trigger an early exit
A loan should not be opened until the user understands how it can be closed.
A Safer Suilend Risk-Management Routine
A disciplined process can reduce many common errors.
Before borrowing:
Choose well-understood collateral.
Review its LTV and liquidation parameters.
Examine Borrow APR and utilization.
Stress-test a significant collateral decline.
Borrow well below the maximum.
Establish a personal Health Factor limit.
Keep repayment funds and SUI available.
Define an exit plan.
After borrowing:
Monitor collateral and debt prices.
Track accumulated interest.
Review changes in Borrow APR.
Check the Health Bar regularly.
Reduce debt before the position becomes critical.
Reassess whether the loan still serves its original purpose.
This routine cannot eliminate market or smart-contract risk, but it helps prevent avoidable liquidation caused by poor position management.
Key Indicators Every Borrower Should Track
Loan-to-Value Ratio
Shows the current relationship between debt and collateral.
Health Factor
Summarizes the position’s safety after asset-specific liquidation parameters are applied.
Liquidation Threshold
Defines the point at which third-party liquidators can begin reducing the position.
Borrow APR
Shows the current annualized cost of the debt.
Utilization
Indicates how much of the borrowed asset’s reserve is already in use and helps explain rate changes.
Total Debt
Includes the original loan and accrued interest.
Available Liquidity
Shows whether funds are available for borrowing, withdrawal, or position management.
These indicators should be interpreted together. A low Borrow APR does not make a high-LTV position safe, and a strong Health Factor does not remove smart-contract or asset risk.
FAQ
What is the most common borrowing mistake on Suilend?
One of the most common mistakes is borrowing close to the maximum available amount and leaving too little collateral buffer to withstand volatility or accumulated interest.
Why is a high LTV dangerous?
A high LTV means debt represents a large share of the collateral value. Even a moderate adverse market movement can move the position toward liquidation.
How does the collateral ratio change?
It changes when collateral prices move, borrowed assets change in value, interest accumulates, or the user adds or removes collateral.
What happens when the Health Factor becomes too low?
When the Health Bar reaches the Liquidation Threshold, third-party liquidators can repay part of the debt and receive collateral plus a liquidation incentive.
Can a position be liquidated even if collateral does not fall?
Yes. Liquidation risk can increase when the borrowed asset appreciates or accumulated interest raises the debt balance.
How often should a Suilend loan be monitored?
Active loans should be reviewed regularly and more frequently during volatile markets, high utilization, or rapidly changing borrowing rates.
What is the best way to reduce liquidation risk?
Borrow conservatively, maintain a strong Health Factor, keep repayment liquidity available, monitor both collateral and debt, and act before the account approaches its liquidation threshold.
Conclusion
The most common mistakes on Suilend are usually connected to excessive borrowing and insufficient monitoring.
Users may treat maximum borrowing capacity as a target, ignore the collateral ratio, use an unnecessarily high LTV, or assume that the Health Factor will remain unchanged. In reality, every borrowing position evolves as asset prices and interest rates move.
A high LTV provides more immediate liquidity but leaves less room for volatility. Accumulated interest increases debt, while rising utilization can make borrowing more expensive. When account health reaches the Liquidation Threshold, liquidators can sell part of the collateral and charge an incentive.
The strongest protection is conservative position sizing. Borrow substantially less than the permitted maximum, use collateral with reliable liquidity and pricing, and keep part of the borrowed asset available for repayment.
Monitor the Health Factor, LTV, Borrow APR, collateral value, debt value, and reserve utilization throughout the life of the loan. Establish personal warning levels and act before liquidation becomes possible.
Suilend can provide useful liquidity without requiring an immediate asset sale, but the benefit depends on maintaining control of the position. A borrower who monitors risk and keeps a wide collateral buffer decides when to repay or sell. A borrower who ignores these indicators may leave that decision to the liquidation mechanism.
