Loopscale vs Nolus: Loan Terms or a Rate Locked at Open?

Loopscale is a lending app on Solana that matches lenders and borrowers on an order book, each loan at a fixed rate for a fixed term. The default term is one day: when it ends, the loan renews itself with whichever lender is cheapest that day, at that lender's rate. A Nolus position fixes its rate the day it opens, for as long as it stays open, with no term to renew.

This article follows one $1,000 SOL long at 2.5x both ways: what the rate does after the first day, what a fall in SOL sells, and what a calm month costs. For people who lend rather than borrow, it also sets Loopscale's lending vaults next to Nolus Earn. Every live number was read on October 26, 2026, with SOL at $101.41, and borrowing rates are given the way the Nolus app shows them: a monthly rate on the whole position.

Loopscale vs Nolus: Two Ways to Borrow for SOL

Most lending apps pool every lender's money and let a formula set one rate for everyone, which moves with how much of the pool is lent out. Loopscale works like a market instead. Lenders post offers, each with a rate, a term and how much they will lend against a given collateral, the asset you lock up to secure the loan. A borrower takes the cheapest offer that fits. If the collateral's value falls too far, the app sells some of it to repay the lender, which is called a liquidation.

How Does Loopscale Work?

Every Loopscale loan has a fixed rate for a fixed term, from one day to three months, depending on what lenders offer. The default way to borrow, Quick Borrow, uses one-day terms. On the day, Loopscale's public quote showed about $7,430 of one-day offers for USDC borrowed against SOL, at 0.54% to 0.60% a month for a position like this one.

When a term ends, Loopscale's auto-refinance, which is on by default, rolls the loan into a new one-day term with the cheapest lender at that moment. In Loopscale's words, "This process can repeat indefinitely, as long as your loan remains healthy". So the rate is fixed for one day at a time.

Loopscale also runs Loops, one-click positions that borrow against a token and buy more of it to multiply the yield it earns, and lending vaults, where a manager called a curator lends one asset out on the book for its depositors. Both come up below.

How a Nolus Position Works

On Nolus you put in $1,000 and the protocol lends you the rest. At 2.5x it lends $1,500, and the position buys $2,500 of real SOL in one step. You pick the leverage, up to 5x. The interest rate is fixed the day you open: a position opened that day got 0.71% a month, as the app shows it. There is no term. The loan lasts as long as the position, and the rate can't change while it is open.

Both monthly costs count 30 days of interest on the $1,500 borrowed and the swaps. Loopscale's assumes each of the 30 daily rates stays where it was on the first day; each one could come in higher or lower.

A Rate Fixed for a Day: When a Loopscale Loan Ends

A one-day term means the rate is fixed for one day. Each renewal takes whatever the cheapest lender asks at that moment, higher or lower, and Loopscale's own risk page warns that the new rate "may be significantly higher than the rate at which you started". Over 30 days the $1,500 in this example would be priced 30 times.

A renewal also needs a lender. If none matches, Loopscale gives the loan a 48-hour grace period at the old rate, in which you can repay or refinance by hand. After that, in its words, "your position may be partially liquidated to cover the outstanding debt." Some of your SOL would be sold, whatever SOL's price is doing. Loopscale says this is rare: healthy loans "are highly unlikely to default due to failed refinancing". Still, the depth of the book is part of your risk. The public quote showed about $7,430 of one-day USDC offers against SOL that day, and Loopscale's three largest USDC vaults had 93% to 99.7% of their deposits lent out.

You can pick a longer term where a lender offers one, which fixes the rate for longer; when it ends, auto-refinance moves the loan back to one-day terms. You can also switch auto-refinance off, and then the loan must be repaid when its term ends or the collateral is liquidated. Loopscale counts a term's full interest as debt from the first day, "the total interest that will accrue over the full loan term", so a longer term starts slightly closer to the liquidation line.

On Nolus there is nothing to renew. The rate you open at is the rate you keep: it doesn't rise if market rates rise, and it doesn't fall if they fall. The loan lasts as long as the position. What comes due is interest, every 30 days: you pay it then, or the protocol sells a little of the position's SOL to cover it.

When SOL Falls: What Each One Sells

Both apps watch the same number: the debt as a share of what the SOL is worth. Loopscale's SOL offers that day let you borrow up to 80% and set the liquidation line at 90%. Nolus also starts selling at 90%. At 2.5x the debt starts at 60%, so on both, nothing is sold until SOL falls about 33%, to about $67.61.

What happens at the line is where they differ. Loopscale sells enough SOL to bring the debt back below 80%, the borrowing limit, not just back under the 90% line. Every dollar of SOL sold repays a dollar of debt, so getting from 90% down to 80% takes a lot: $833 of the $1,667 of SOL in the position, half of it. The buyer, one of the liquidators Loopscale approves, earns a fee that grows the further past the line the loan is when sold, 0.5% for a loan sold at 90.5%. A vault's curator can add a penalty on top.

Nolus sells only enough to bring the debt back to 83% of the position's value: $686 of SOL, about 41% of it, with a $0 penalty on a partial liquidation. Before that, the position sends three warnings, as the debt passes 85%, 86.5% and 88%. Nolus liquidates on the trend, not on a brief spike in price, as Market Anomaly Guard explains; Loopscale says its liquidations use price smoothing too. A full liquidation can still happen on either app. Liquidations on Nolus walks through each step.

The difference shows when SOL comes back. Say SOL falls to the line, the first sale happens, and SOL then returns to $101.41. The Nolus position kept more SOL, 14.50 against 12.33, so it still owes more, $813.73 against $666.67, but it gains more on the way back. After 30 days of interest, at 0.71% a month on Nolus and about 0.55% a month on Loopscale borrowing USDC, and the swaps, the Nolus position is worth $639.31 and the Loopscale position $569.38, before Loopscale's liquidation fee.

If SOL keeps falling instead, the extra SOL Nolus kept falls with it. At $62.35, just before the next Nolus sale, the Nolus position is worth about $90 against about $102 on Loopscale. Loopscale's next sale comes later, at about $60.09, and each app again takes the same share of what is left: about 41% on Nolus, half on Loopscale.

What Is DeFi Looping?

Looping means borrowing against a token, buying more of the same token, adding it as collateral and repeating, so a deposit carries more of the asset than you put in. Each round adds leverage. A Loop on Loopscale does the whole cycle in one transaction: it borrows the full amount for an instant through a flash loan, buys the collateral, deposits it, borrows against it and repays the flash loan.

Loopscale built Loops for yield. It describes them as "leveraged exposure to yield-bearing assets", and most pair a token that earns interest or staking rewards with the asset it tracks: staked SOL against SOL, up to 10x, or yield-earning dollar tokens against USDC. Staked SOL and SOL move together, so the leverage doesn't multiply SOL's price moves; the deposit still rises and falls with SOL, one for one. What the leverage multiplies is the gap between the staking yield and the borrow rate.

That gap decides whether a loop earns or loses. That day, the Loop of JupSOL, one kind of staked SOL, against SOL showed 6.22% a year at 10x, while the Loop of JitoSOL, another, showed a loss of 7.01% a year at 10x, because borrowing SOL for it cost more than JitoSOL earned. Every swap costs a fee that leverage multiplies too, or in Loopscale's words, "a 3x leveraged Loop will have 3x the fees." Several of its Loops are built on Hylo's xSOL, a leveraged SOL token we set against Nolus in Hylo xSOL vs Nolus.

No Loop borrows a stablecoin against SOL, so none holds 2.5x SOL. The closest one-click route is the Loop of xSOL against SOL, which takes its leverage from Hylo's pool. A 2.5x position that holds SOL itself has to be built by hand on the Borrow page: swap $1,000 to SOL and deposit it, borrow $800 of USDC, swap it to SOL and add it, borrow $640 more, swap and add, then borrow the last $60, swap and add. That is four swaps and three rounds of borrowing for one position, each loan on one-day terms. On Nolus your $1,000 and one loan buy the $2,500 of SOL in a single step, and nothing loops.

Loopscale Fees and What a Month Costs

Loopscale charges no fee of its own: its docs list none, and DefiLlama records no protocol revenue. On the lending side, each vault's curator keeps a share of the interest, 5% to 25% across its vaults, and no vault charged an origination fee that day. A position built by hand pays for its swaps, which come to cents: about 31 cents on this size for the four buys and the sale at close.

Interest is where the two differ. At that day's one-day rates, borrowing USDC cost about 0.55% a month and borrowing USDT, Tether's dollar stablecoin, 0.18%. Over 30 days the $1,500 loan would cost $13.65 or $4.32. Both assume every daily rate stays where it was on the first day; each one could come in higher or lower.

Nolus charges no fee of its own to open or close a position; the swap that buys and sells the SOL costs about 16 cents. Interest is 0.71% a month, fixed the day the position opens. Over 30 days it comes to $17.38, $17.55 with the swap. The rate can't change while the position is open, so it doesn't fall if market rates do. What a leveraged SOL trade really costs sets that fixed rate against the variable rates of other Solana lending apps.

So 30 calm days cost more on Nolus at the day's rates: about $3.60 more than borrowing USDC on Loopscale, and about $12.90 more than borrowing USDT. That is the price of a rate that never re-prices, a loan that never needs a new lender, and a first sale that takes less, with a $0 penalty on a partial liquidation.

For Lenders: Loopscale Vaults vs Nolus Earn

Lending on Loopscale mostly goes through its vaults. You deposit one asset, and the vault's curator, usually Loopscale's own curation team, lends it out on the book. That day its three largest USDC vaults paid 6.45% to 8.20% a year after the curator's share, plus 0.13% to 2.40% in rewards, and had 93% to 99.7% of their deposits lent out. Withdrawals are instant only from a small buffer each vault keeps; beyond it you pay a fee to leave at once or wait in a queue.

Nolus USDC Earn paid 10.49% a year that day. Its yield is the interest users pay on their positions, and the pool rate goes to lenders whole. 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, and 29.3% of the pool was free that day.

On $1,000 over 30 days, Nolus Earn comes to $8.23, against $5.15 to $6.50 in those Loopscale vaults before rewards and $5.65 to $7.06 with them. The Nolus pool is far smaller, about 221,000 USDC against about $24.1 million in Loopscale's largest USDC vault, 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

Loopscale fits when you want leveraged yield on assets that move together, such as staked SOL against SOL, when you want to borrow against collateral few apps take, such as positions in exchange liquidity pools or yield-earning dollar tokens, or when you want a rate the market sets again every day, which can fall as well as rise.

Nolus fits when:

• You want leverage on the asset's price, in one position that holds real SOL, at the leverage you pick, up to 5x.
• You want to open in one step: your $1,000 and one loan buy the SOL, one swap in and one out, rather than four swaps and three rounds of borrowing.
• You want the rate fixed for as long as the position is open, with no term to renew and no new lender to find.
• You want the first sale to take less. At 2.5x, nothing is sold until SOL is about 33% down, after three warnings, and the first sale takes about 41% of the SOL rather than half, with a $0 penalty on a partial liquidation. A full liquidation can still happen.
• You want more than a SOL long: Nolus has shorts on SOL, cbBTC and wETH, and longs on more assets than SOL.
• You lend USDC and want the interest users pay, with no lockup, no points and no token rewards to count on.

What you are choosing between is when your terms are set. Loopscale sets them every day, at whatever the market asks; Nolus sets them once, the day you open, and keeps them. What that costs on Nolus is more interest over 30 calm days: about $3.60 to $12.90 on this example at the day's rates, depending on whether you would borrow USDC or USDT on Loopscale.

Borrowing rates are shown as the Nolus app shows them, a twelfth of the yearly rate on the loan, times the loan's share of the position (Nolus 14.1% a year; Loopscale's one-day offers 10.90% to 11.99% on USDC and 3.50% on USDT). Loopscale's interest takes the cheapest one-day offers that cover $1,500 on its public quote and assumes each daily rate holds for 30 days. Liquidation figures use each app's own line and selling rule, with no top-ups; the dip-and-back figures count 30 days of interest and the swaps; every dollar figure counts 30 days, a little under the app's month of a twelfth of a year.
