How a Loop executes

01
Deposit asset
Deposit your yield-bearing asset (e.g. JitoSOL) as initial collateral.
02
Borrow
Flash borrow SOL against your collateral at a fixed rate.
03
Redeposit
Swap borrowed SOL for more JitoSOL, redeposit as collateral. Repeat.
04
Earn
The position accrues leveraged staking yield while your borrow cost is fixed.
Single Atomic Transaction
The full loop executes in one Solana transaction. No partial states, no multi-step risk.
📉
Market-Neutral Strategies
Amplify yield without directional price exposure. Your net return comes from the yield-rate spread.
📐
Directional Loops
Take on price exposure alongside yield by looping into assets you believe will appreciate.
Security

Built to isolate risk at every layer.

Loopscale's architecture is designed so that problems in one market never affect other markets, lenders, or borrowers elsewhere in the protocol.

🔐
Isolated Collateral Markets
Each market is a separate, independent module. A liquidation event or oracle anomaly in one market is fully contained. Other markets continue to operate normally.
🔮
Enhanced Price Oracles
Multiple redundant price feeds with on-chain verification and circuit breakers prevent oracle manipulation. Post-audit oracle upgrades were completed following the April 2025 security review.
⏱️
Per-Market Supply Caps
Borrow and supply caps limit maximum exposure concentration in any single market, preventing systemic overexposure to any one collateral type or asset.

Mandatory Audits
All protocol updates undergo formal third-party review before deployment. No program functionality ships without completed audit sign-off — a standard Loopscale commits to maintaining.

FAQ

30 Common Questions

Everything you need to know about Loopscale's fixed-rate order book lending protocol.

Loopscale is a modular, order book-based lending protocol built on Solana. It matches lenders and borrowers directly at fixed rates and terms, rather than pooling liquidity into shared reserves. Lenders earn the full borrow rate with no spread dilution; borrowers lock in predictable costs for the entire loan duration.
Traditional pool-based protocols aggregate deposits into shared reserves and set variable rates algorithmically based on utilization. On Loopscale, each lender creates a specific offer — defining which collateral they accept, the rate, and the term. Borrowers match against the best available offer. Both parties lock their rate for the full duration with no rate volatility mid-loan.
Loopscale supports over 40 asset types: liquid staked tokens (JitoSOL, JupSOL, fragSOL), LP tokens from Solana DEXes, yield-bearing tokens, principal tokens from Exponent and RateX, tokenized real-world assets, and many more. Each market defines its own eligible collateral independently so new assets can be added without protocol-wide risk decisions.
Fixed-term loans are available for 1 day, 1 week, 1 month, or 3 months. The rate is locked for the entire term once a match is made. To exit early, borrowers can sell their loan position on the secondary order book and receive any remaining collateral after the debt is settled.
Loopscale Vaults are curated lending strategies managed by third-party experts. Deposit a single asset and the vault curator allocates it across multiple markets automatically — optimizing yield while managing risk parameters. The SOL GENESIS Vault has consistently delivered over 10% APR. Many vaults offer liquidity buffers for instant withdrawals; others use a queue system or small early-exit fee.
Loops are one-click leveraged yield strategies that execute a recursive borrow-and-redeposit sequence in a single atomic transaction. Deposit a yield-bearing asset, borrow against it at a fixed rate, swap borrowed funds for more of the same asset, redeposit as collateral, and repeat — up to 9x leverage while locking in a fixed borrowing cost for the chosen term.
Loops support up to 9x leverage with fixed borrowing costs locked for up to 3 months. For new users, 2x is recommended to understand the mechanics and liquidation dynamics. Each loop position displays the net APY and liquidation threshold clearly before you confirm the transaction.
Advanced Lending lets you place limit offers with fully custom parameters: which collateral types you accept, your target APR by duration, the maximum LTV you allow, and whether idle capital earns variable-rate yield via Optimized Yield while waiting for a match. Your liquidity is reusable across all matching markets simultaneously.
Virtual Markets let you define a ruleset — acceptable collateral, target APRs, and durations — and Loopscale aggregates all matching opportunities into one unified market view automatically. This concentrates your liquidity, reduces fragmentation, and maximizes match probability without requiring you to manage multiple separate offers.
If a borrower's collateral value falls below the market's liquidation threshold (typically 82.5% LTV), automated on-chain liquidation is triggered. Collateral is sold to recover the loan principal plus accrued interest and returned directly to the lender. Because markets are isolated, a liquidation in one market has zero effect on positions in any other market.
Lenders can withdraw unused liquidity at any time. If your capital is deployed in an active loan, sell that loan position on the secondary order book to exit early and claim all accrued interest. Borrowers can repay early at any time — interest accrues only up to the actual repayment date, not the full term.
Rates are market-driven, not algorithmic. Lenders post minimum APR offers; borrowers take the best available offer from the order book. Both sides lock the agreed rate for the full term at the moment of matching. This creates a true fixed-rate instrument — closer to a term deposit or bond than a variable-rate revolving line.
Loopscale Points track all on-chain activity: lending, borrowing, looping, and referrals. Referring a user earns 5% of all their non-referral points indefinitely with no cap. Certain positions carry bonus multipliers and external partner points from Solayer, Meteora, marginfi, and OnRe. Points track protocol participation and may be considered for future incentives.
Loopscale has completed multiple third-party security audits and mandates formal review for all future program updates. The protocol uses isolated collateral markets, enhanced Pyth price oracles, and per-market borrow and supply caps. An April 2025 oracle exploit was fully resolved within 72 hours via white-hat bounty recovery. No incidents have occurred since. An active bug bounty program continues.
Loopscale supports all major Solana-compatible wallets: Phantom, Solflare, Backpack, and any WalletConnect-compatible wallet. No account creation, no KYC, no email required. Simply connect your wallet to access all protocol features immediately.
Loopscale charges no spread between borrow and lend rates — lenders earn exactly what borrowers pay. Solana network fees (~$0.001) apply to all on-chain actions. Some vault strategies may include a curator management or performance fee, clearly disclosed before you deposit. No hidden withdrawal or deposit fees exist.
Yes. Loopscale's modular architecture allows any verified asset to be listed in an isolated market immediately. Tokenized stocks (xStocks), RWA tokens, and other emerging on-chain primitives are actively supported. New markets form organically as soon as there is lender and borrower interest — no protocol-wide governance vote required.
The Loopscale portfolio section shows all active positions: lend offers, active loans, vault deposits, and loop positions in one view. P&L cards provide real-time return tracking, including daily accrued interest, points earned, and net APY accounting for borrowing costs on leveraged loop positions.
There is no enforced minimum for lending or borrowing. Solana's sub-$0.001 network fees keep even small positions cost-effective. For loop positions, the practical minimum depends on the specific market's parameters and acceptable slippage thresholds, clearly displayed in the UI before you confirm.
Full documentation, SDK access, API references, and integration guides are available in the Loopscale Docs. Developers can build on Loopscale's lending infrastructure with permissionless API access. The GitHub repository is publicly available and an active bug bounty program rewards responsible disclosure of security vulnerabilities.
When a loan reaches maturity, Loopscale automatically attempts to refinance at current market rates unless the borrower has disabled auto-refinancing. This provides continuity for both lenders and borrowers. If no matching offer is available for refinancing and the borrower has not repaid, the position may enter liquidation to protect the lender.
Market-neutral Loops amplify yield from the spread between a yield-bearing asset's staking return and the fixed borrowing cost — without directional price exposure. Your net return comes from the yield-rate differential only. Directional Loops additionally benefit if the looped asset appreciates in price, creating a leveraged long position alongside yield amplification.
Yes. LP tokens from major Solana DEXes — including Orca, Raydium, and Meteora — are supported as collateral in isolated markets. This lets liquidity providers access loans without exiting their LP positions, continuing to earn trading fees while borrowing against the position's value.
Loopscale uses Pyth Network price feeds combined with protocol-specific feeds for complex assets like LP tokens and staked tokens. Following the April 2025 security review, oracle infrastructure was significantly enhanced with additional redundancy, circuit breakers, per-market supply caps, and manipulation-resistant pricing mechanisms.
Yes. Because each Loopscale market is isolated, lenders can choose to accept long-tail collateral — including niche and memecoin tokens — without exposing the broader protocol. Lenders accepting higher-risk collateral typically charge higher rates, and each market independently sets its own LTV and liquidation parameters.
Borrowers can repay at any time before maturity. Interest accrues only up to the actual repayment date — not the full term — making early repayment cost-effective. Alternatively, borrowers can sell their active loan position on the secondary order book and keep any collateral remaining after the debt is settled.
When you refer a new user, you earn 5% of all non-referral points they accumulate through their on-chain activity — lending, borrowing, looping, and vault deposits — indefinitely with no cap. Connecting your X and Discord accounts awards an immediate 5,000 points on first connection. Some campaigns carry time-limited bonus multipliers announced through official channels.
Any individual or team can apply to become a Vault curator. Curators design lending strategies by defining collateral types, LTV ratios, interest rate targets, and duration allocations — earning management or performance fees on vault deposits. Changes to high-risk parameters trigger a 24-hour cooldown giving depositors time to review and exit before the change takes effect.
Optimized Yield automatically routes unmatched lender capital to external variable-rate protocols such as marginfi while waiting for an order book match. This eliminates idle capital drag — instead of earning nothing while waiting, your funds earn a competitive variable rate until a fixed-rate match is found and capital is redeployed.
Unlike Aave and Kamino — which use variable rates determined by pool utilization — Loopscale offers fixed rates for the full loan term. Lenders earn exactly what borrowers pay with no spread dilution from idle capital. Loopscale also supports a broader range of collateral types through its isolated market architecture, preventing risk contagion between asset types. The main trade-off is that early exits require selling loan positions on the secondary order book rather than instant repayment.
