Loopscale Expands Earn With Curated Vaults, Bringing Managed Lending Strategies to Solana DeFi

Loopscale has built its Earn product around a curator model that delegates active lending strategy management to third parties, giving passive depositors on Solana access to fixed-rate yield across multiple markets without requiring them to manage individual loan parameters.

How Curated Vaults Work

Each vault designates a Curator (an individual or team) responsible for allocating depositor capital across Loopscale's order-book lending markets. Curators set the eligible collateral types, loan-to-value thresholds, fixed-rate borrow terms, loan size caps, and liquidity buffers for their vault. Depositors supply a single asset (typically USDC or SOL) and the curator handles deployment from there.

A key structural safeguard: curators cannot withdraw user deposits. Their authority is limited to parameter management. Changes to high-risk parameters (collateral types, LTV thresholds) trigger a 24-hour cooldown before taking effect, giving depositors a window to exit if they disagree with a strategy shift. Lower-risk adjustments can be applied immediately.

Curators earn fees via origination charges on new loans and a percentage of interest the vault generates. They may also distribute token rewards to depositors on a curator-defined schedule.

Growth Trajectory and RWA Concentration

Loopscale launched in April 2025 and reached $62 million in deposits by the end of Q2 that year, with more than $1 billion in cumulative borrowing volume across 4,574 active loans, according to its Q2 2025 recap. By the end of Q1 2026, total deposits had grown to $141 million, with real-world assets representing roughly 40% of that figure.

The RWA concentration reflects an unusual mix for Solana DeFi. Per the same Q1 recap, OnRe's ONyc reinsurance yield token grew from $15 million to more than $23 million in deposits during Q1 alone, representing 43% of Loopscale's total market. Maple Finance's syrupUSDC reached $15 million within its first month on the platform, while Hastra's PRIME token, backed by Figure's HELOC lending operations, hit $10 million in deposits within weeks of launch. Apollo-backed ACRED accounted for nearly 95% of all ACRED minted on Solana by quarter-end.

DeFiLlama currently shows $73 million in TVL and $46.78 million in active loans, with $337,000 in cumulative protocol fees, a figure that reflects the platform's early stage relative to its deposit base.

Loops 2.0 and Vault LP Collateral

In April 2026, Loopscale shipped Loops 2.0, a revamped interface for leveraged yield strategies that lets users deposit yield-bearing tokens and atomically borrow against them at fixed rates. The protocol also allows vault LP tokens to serve as collateral for separate borrowing positions, enabling a depositor to earn lending yield while simultaneously using that same deposit as collateral: a two-layer yield structure that other Solana lending protocols have not offered at the same fixed-rate granularity.

Vault strategy types span a range of risk profiles. Conservative vaults target liquid, low-volatility collateral for stable returns. Higher-yield vaults may accept LP tokens or leveraged collateral exposure, with curators responsible for disclosing and managing that additional risk.

The April 2025 Exploit

The platform's expansion comes after a significant early security event. On April 26, 2025, just over two weeks after launch, an attacker exploited an oracle pricing vulnerability in Loopscale's RateX PT token integration, draining approximately $5.7 million in USDC and 1,200 SOL from the protocol's Genesis Vaults. The attacker had taken out undercollateralized loans by exploiting a mismatch between the protocol's assessment of PT token value and actual market prices.

Loopscale offered a 10% bounty in exchange for return of 90% of the stolen funds and full legal immunity. The attacker accepted, returning all funds within 48 hours. No users suffered losses. The protocol subsequently completed multiple third-party audits, introduced borrow and supply caps, added collateral exposure limits per asset, and established mandatory external review for all future program updates. Three further audits were completed during Q1 2026, per the company's quarterly recap.

Order-Book Lending and the Curator Bet

The curator model is a departure from the liquidity-pool approach that dominates Solana DeFi lending. Protocols like Kamino and marginfi aggregate lender capital into shared pools where borrowing rates float with utilization. Loopscale's order-book structure matches individual loans at fixed rates, and the vault layer gives passive lenders access to that market without navigating individual offers.

Whether the model can sustain its deposit growth as incentive programs mature will be a cleaner test of its core design. The RWA-heavy composition (reinsurance yield tokens, HELOC-backed credit, tokenized treasuries) is itself a differentiated position: more institutional credit exposure than most Solana DeFi protocols have targeted, and a concentration that will reflect the credit performance of those underlying assets alongside Loopscale's own platform mechanics.
