Hylo xSOL is a leveraged token, and a Nolus position is spot margin. Both give you leveraged SOL with no funding fees, the regular payments that perpetual futures charge to keep their price near the market. The difference is who sets the leverage: Hylo xSOL takes it from a pool you share with every other holder, while a Nolus position is your own loan, at the leverage you choose. That one difference decides what happens to your money when SOL moves.
This article follows $1,000 both ways at the same leverage: Hylo xSOL, and a Nolus SOL long opened at 2.73x, the leverage xSOL ran at on October 23, 2026, with SOL at $104.60. Hylo V2, live since July 13, 2026, is the product described; anything earlier is history. For people who lend rather than borrow, the article also sets Hylo's Earn Pool, where hyUSD holders deposit to earn yield, next to Nolus USDC Earn.
Leveraged Tokens vs Margin: Two Ways to Hold SOL
A leveraged token is a token whose price moves by a multiple of an asset's price, with the borrowing done inside the product rather than in your name. Margin is the other way: you borrow to buy more of the asset itself, the spot asset rather than a contract on its price, and the loan and the position are yours. xSOL is the first kind. Nolus is the second.
How Hylo xSOL Works
Hylo holds a pool of staked SOL, mostly jitoSOL, which is SOL that earns staking rewards while it stays tradable. The pool is split in two. One part is a debt fixed at $1 a unit, which backs hyUSD, Hylo's stablecoin. xSOL owns everything above that debt, so it takes all of the pool's gains and losses.
The pool's value divided by its debt is called the collateral ratio. On the day, the SOL pool held $157.85 of SOL for every $100 it owed, a ratio of 157.85%. The $57.85 above the debt belongs to xSOL holders and carries the price moves of all $157.85, which works out to 2.73x leverage.
That leverage belongs to the pool, not to you. It moves when SOL moves, and it moves when other holders mint or redeem xSOL or hyUSD, which means buying new tokens from Hylo or cashing them in. From October 2025 to October 2026 it ranged from about 1.8x to 4.2x. Hylo aims for a 150% ratio, which is 3x, and when the ratio leaves its normal band of 135% to 165%, it opens a route that pulls the ratio back into the band.
How a Nolus Position Works
On Nolus you put in $1,000 and the protocol lends you the rest. At 2.73x it lends $1,730, and the position buys $2,730 of real SOL. You pick the leverage, up to 5x. The interest rate is fixed the day you open and charged only on the part you borrow: a position opened on the day got 14.1% a year. The line where the protocol would start selling is set the day you open too, and the position form shows its price before you open. Every position is isolated, so nothing another user does changes yours.
| Nolus | Hylo xSOL | |
|---|---|---|
| What do you hold? | A position that holds real SOL | A token with a claim on a shared pool of staked SOL |
| Who sets the leverage? | You, up to 5x | The pool, 2.73x on the day |
| Can other people's trades change your leverage? | No | Yes |
| What does it cost to get in and out? | No Nolus fee; about 20 cents for the swap | 1% in and 1% out |
| What does getting out cost when SOL falls? | No Nolus fee; the swap costs cents | 4%, then 8%; redemptions stop at a 100% ratio |
| What does holding it cost? | 14.1% a year, fixed at open, on the $1,730 borrowed | No interest unless the ratio rises above 165% |
| Does the SOL earn staking yield for you? | No | No, it goes to Hylo's Earn Pool and treasury |
| How far can SOL fall before anything is sold? | About 29%, with interest paid when due | About 14% |
| What is $1,000 worth after SOL falls 20% and comes back? | $979.73, after a month of interest and the swap | $980.10 if the pool sells nothing, about $901 if it sells at every step down |
| Can it go to zero? | Yes, a full liquidation can still happen | Yes, for every holder at once, at a 100% ratio |
| Can you go short, to gain when the price falls? | Yes, on SOL, cbBTC (Bitcoin) and wETH (Ether) | No, long only |
The 14% for xSOL assumes nothing else in its pool changes on the way down; the next section explains why that matters. The 29% for Nolus counts a month of interest. Interest falls due every 30 days, and any left unpaid past its due date is collected by selling a little of the position's SOL.
Leverage Without Liquidation: What It Means on Hylo xSOL
Hylo calls xSOL liquidation-resistant: nobody closes your position, and nobody asks you to add money. That holds. What it does not mean is that a fall can't cost you, because the losses arrive through the token's price and through what the pool does to protect hyUSD.
Take $1,000 of Hylo xSOL with the pool at 157.85%. If nothing else in the pool changed, the ratio would fall in step with SOL, and three lines would matter.
- About a 14% fall, SOL near $89.46. The ratio reaches 135%. The pool opens a route that lets arbitrageurs, outside buyers who profit from price gaps, buy its SOL for USDC. When they take it, that lowers xSOL's leverage by selling SOL after it has fallen. The fee to get out rises from 1% to 4%: about $24 on what your xSOL is then worth, about $605.
- About a 24% fall, near $79.52. The ratio reaches 120%, and the fee to get out is 8%: about $28 on about $346.
- About a 37% fall, near $66.26. The ratio reaches 100%. The pool's SOL no longer covers its debt, xSOL is worth zero for every holder at once, and minting and redeeming stop. From there Hylo burns hyUSD from its Earn Pool to cover the gap.
In practice the selling between those lines lowers the leverage and pushes the zero line further down, which is what it is for. It has rarely been needed. Since V2 went live, the SOL pool's selling route has been used on one day, for about $4,200 of SOL on August 1, 2026, and the pool's daily readings since then have not gone below about 137%. Hylo describes the 4% and 8% fees as a backstop that "almost never apply".
A Nolus position at the same 2.73x sells nothing at either of the first two lines. Its first partial liquidation comes at $74.50, about 29% down, counting a month of interest on the loan. Three on-chain warnings come first. Then a partial liquidation sells only enough SOL to bring the debt back to 83% of the position's value, at market, with a $0 penalty on a partial liquidation, and the position stays open.
If SOL kept falling, the next partial sales would come at about $68.71 and $63.36. At $66.26, the price where xSOL would reach zero if nothing else changed, the Nolus position has been through two partial sales and still holds about $83. A full liquidation can still happen; how Nolus liquidations work explains when. At every one of those prices you can close with no Nolus fee, and the swap that sells the SOL costs cents.
Volatility Decay in a Dip That Comes Back
Now suppose SOL falls 20% and comes all the way back.
Hylo's docs warn that "volatility decay causes leveraged tokens to lose value over time in sideways markets". A token that rebalances sells some of its asset after a fall and buys after a rise, so on a round trip it sells low and buys back higher. Hylo's own illustration, at 2x: SOL is at $100 and xSOL at $100; SOL drops 20% to $80 and xSOL 40% to $60; SOL recovers to $100, but xSOL only to $90.
The Hylo xSOL pool rebalances only once its ratio leaves the 135% to 165% band. Inside the band, and with nothing else in the pool changing, its debt stays fixed, so a dip that stays in the band and comes back leaves xSOL where it started. A 20% fall from the day's ratio would take it to about 126%, below the band, where the pool opens its SOL to buyers, and whatever SOL it sells near the bottom misses the recovery. So $1,000 of xSOL comes back as $980.10 after its 1% fees in and out if nobody takes that route, and as about $901 if buyers take it at every step down, holding the ratio at 135%.
A Nolus position at 2.73x goes through the same round trip without a sale. At the bottom its debt would be about 80% of its value, short of even the first warning at 85%, so nothing is liquidated. When SOL comes back, the position is where it started, less the interest and the swap: $979.73 if the dip and the recovery take a month. A Nolus position never rebalances, so as long as a dip stays above its first line, how deep it goes changes nothing.
A Long Slide
The past year was the hard version of that test. On Hylo's own figures, Hylo xSOL went from about $1.54 on October 22, 2025 to about $0.06 on October 22, 2026, down 96%, while SOL fell 43%. At SOL's low on June 6, 2026, about two thirds below where it started, xSOL was 99% below its high of October 26, 2025.
Two things drove it. The pool's leverage rose into the fall, from 2.25x at the start to 4.2x in February and March 2026, so each further drop hit harder. And Hylo's first version, whenever the pool's ratio fell below 130%, converted hyUSD deposited in its Stability Pool into new xSOL. That kept the ratio from reaching 100%, and together with new mints it took xSOL's supply from about 14 million tokens to 235 million by June 8, 2026. It also cut the leverage near the bottom, so the recovery that followed lifted xSOL less. V2 removed that conversion, and since it went live on July 13, 2026, xSOL has more than doubled while SOL rose 38%.
Most of the loss is what leverage does on a path like that: a token that resets to 3x every day would have lost about 95% on the same SOL prices. Any SOL long at 2x or more held through that fall without adding money lost nearly everything, on any app. What differs is who sets the leverage on the way down.
What It Costs to Hold
Hylo xSOL charges no interest while its pool's ratio stays between 135% and 165%, where it sat on the day. What you pay is the 1% to get in and the 1% to get out: $10 in, leaving $990 of xSOL, and $9.90 out if SOL ends where it started, $19.90 in all. Above a 165% ratio, xSOL holders pay extra. What funds xSOL's leverage is the staking yield: the pool's SOL is staked, and the yield on the $2,730 behind $1,000 of xSOL, about $134 a year at jitoSOL's 4.9%, goes to Hylo's Earn Pool and treasury rather than to you. The SOL in a Nolus position earns nothing either, so that is no extra cost next to Nolus; it is how xSOL's leverage gets paid for.
Nolus charges no fee of its own to open or close a position; the swap that buys and sells the SOL costs about 20 cents on this size. Interest runs at 14.1% a year, fixed the day the position opens, on the $1,730 it borrows: $20.05 for a month and $243.93 for a year. It falls due every 30 days: you pay it then, or the protocol sells a little of the position's SOL to cover it. There are no funding fees, and the rate can't change while the position is open. What a leveraged SOL trade really costs sets that fixed rate against the variable rates of other Solana lending apps.
So a month costs about the same either way: about $20.27 on Nolus with the swap, against $19.90 on xSOL. Over a year xSOL is far cheaper to carry, $19.90 against about $244, as long as its pool stays in its normal band. That interest is the price of choosing your own leverage and knowing, the day you open, your rate and where selling would start.
For Lenders
Both apps also pay the people on the other side. Hylo's Earn Pool takes hyUSD and paid 10.60% a year on the day. Its yield is the staking yield from the SOL pool and the borrow rate that holders of Hylo's BTC and HYPE tokens pay, plus or minus what each pool gains or loses when it sells or buys its own assets to get back into its band. It is also Hylo's first-loss capital: if a pool's ratio falls below 100%, the Earn Pool's hyUSD is burned to cover the gap, up to its whole balance, and later yield repays that loss before depositors earn again.
Nolus USDC Earn paid 10.43% that day. Its yield is the interest users pay on their positions, and the pool rate goes to lenders whole, while Hylo splits what it collects between the Earn Pool and its treasury. There are no token emissions (new tokens handed out as a reward) and no points, and the yield compounds automatically. There is no lockup: you can withdraw whatever isn't lent out, at any time. On $1,000 over 30 days the two come to about the same, $8.18 against $8.32 on Hylo. The Nolus pool is far smaller, about 221,000 USDC against about 20.7 million hyUSD in Hylo's Earn Pool, so a large deposit or withdrawal moves its rate more. Where stablecoin yield comes from shows the live Nolus rate and covers the risks of lending USDC.
Which One Fits
Hylo xSOL fits when you want a hands-off long SOL token that you can hold in a wallet and trade on Solana exchanges, at whatever leverage the pool runs, and you expect to hold through calm stretches, when it costs little to carry.
Nolus fits when:
- You want to pick your leverage, up to 5x, and have nobody else's trades change it.
- You want to know your costs the day you open. The rate is fixed at open, interest runs only on the part you borrow, and there are no funding fees.
- You want selling to start late, and the first sale to be partial. At 2.73x, with interest paid when due, nothing is sold until SOL is about 29% down, after three warnings, and the first sale takes only a part, with a $0 penalty on a partial liquidation. A full liquidation can still happen. Nolus liquidates on the trend, not on a brief spike in price, as Market Anomaly Guard explains.
- You want to get out at any price with no Nolus fee, including in a fall; the swap costs cents.
- You want the position to hold the asset. When you close, you can pay it off and keep the SOL, or settle into stablecoins and walk away.
- You want more than a SOL long: Nolus has shorts on SOL, cbBTC and wETH, and longs on more assets than SOL.
What you are choosing between is who holds the controls. On Nolus you set the leverage, and the rate and the line where selling starts are fixed the day you open. xSOL hands them to a pool, which costs little while the pool is calm and decides when to sell and what leaving costs when it isn't. What the Nolus side costs is interest, about $20 a month on $1,000 at 2.73x.

Each fall assumes nothing else in Hylo's pool changes, except where the dip names the pool's selling; Nolus figures count a month of interest on the $1,730 borrowed, and the dip and monthly totals add the swap. The swap cost is the median of read-only quotes for buying and selling $2,730 of SOL on the route Nolus uses. Earn rates are APYs; dollars on $1,000 compound them over 30 days.
Frequently asked questions
What is Hylo xSOL?
xSOL is Hylo's leveraged SOL token. Hylo holds a pool of staked SOL and splits it in two, a debt fixed at $1 a unit that backs its stablecoin hyUSD, and xSOL, which takes everything above that debt. That makes xSOL move by a multiple of SOL's price, 2.73x at the time of writing.
What are leveraged tokens?
Tokens whose price moves by a multiple of an asset's price, with the borrowing done inside the product instead of in your name. On Solana, as with xSOL, you hold the token in your wallet and can move it like any other. The product manages the leverage; you don't choose it.
Can xSOL be liquidated?
Not in the usual sense. Nobody closes your xSOL and there are no margin calls. Losses show up in its price instead. Below a 135% pool ratio the pool opens its SOL to buyers to lower its leverage, and the fee to get out rises to 4%, then 8%. If the ratio reaches 100%, xSOL is worth zero for every holder and redemptions stop.
Can you use leverage without liquidation?
You can use leverage that nobody closes, as with xSOL, but not leverage that cannot lose. On xSOL the loss arrives through the price instead of a sale. On Nolus a position can be liquidated, but a liquidation is partial where it can be: it sells only enough to bring the position back to health, with a $0 penalty on a partial liquidation. A full liquidation can still happen.
Why does xSOL's leverage change?
Because it is the leverage of the whole pool. It rises when SOL falls, when new hyUSD is created or when xSOL is cashed in, and it falls when SOL rises, when new xSOL is bought from Hylo or when hyUSD is cashed in. From October 2025 to October 2026 it ranged from about 1.8x to 4.2x. When the pool's ratio leaves its normal band of 135% to 165%, Hylo opens a route to sell or buy SOL that pulls the ratio back into the band.
What is volatility decay in a leveraged token?
It is value a leveraged token loses when the price swings and comes back. A token that rebalances sells some of its asset after a fall and buys after a rise, so on a round trip it sells low and buys back higher. xSOL's pool does this only once its ratio leaves its 135% to 165% band, so how much xSOL loses depends on how much the pool sells. Hylo's docs illustrate it with xSOL at 2x. SOL falls 20% and recovers, and xSOL ends at $90 from $100.
Can a leveraged token go to zero?
Yes. xSOL reaches zero if its pool's ratio falls to 100%, about a 37% fall in SOL from its price at the time of writing, if nothing else in the pool changed. The pool's selling on the way down is meant to push that point further away. Any leveraged position can lose everything, and on Nolus a full liquidation can still happen.
Are leveraged tokens better than margin?
Neither is better for everyone. Margin on Nolus lets you pick the leverage, fixes your rate and the line where selling starts the day you open, and lets you go short. A leveraged token is simple to hold and, like xSOL in a calm market, can cost less to carry. The difference shows most when the price falls.
