Loopscale Review 2026: Fixed-Rate Lending on Solana, Post-Exploit

Loopscale is a lending protocol on Solana. It describes itself as a non-custodial, order book-based platform that offers fixed-rate borrowing, lending vaults and leveraged strategies. Its design aims to give borrowers and lenders clear terms instead of a pooled rate that moves with demand.

The protocol drew attention in April 2025 when it was exploited for about $5.8 million. One report said the breach affected roughly 12% of total funds, mainly USDC and SOL deposits in its vaults. Later coverage reported that the attacker had agreed to return the stolen money in exchange for a 10% bounty, and that the team had restored loan repayment and top-up features after the attack.

Data from DIA Oracles at one point showed about $134 million in total value locked across 18 pools on a single chain. Third-party analysis in 2026 describes Loopscale as operating on Solana, which means its activity and risks are concentrated on one network.

Loopscale is built on Solana and acts as a matching layer between people who want to borrow and people who want to lend. Instead of a single pool where interest changes with supply and demand, it uses an order book. Lenders post the rate and term they will accept, and borrowers choose from those offers. Each loan has a fixed rate, which means the cost to the borrower and the return to the lender are known when the loan starts.

Collateral backs each loan. If the value of the collateral falls too far, the position can be liquidated under the rules of the market. Because the platform is non-custodial, users keep control of their assets through their own wallet and the smart contracts, rather than handing funds to a company's account.

Vaults add another layer. A depositor can place funds in a vault managed by a curator, who spreads them across loan markets. This is simpler than picking individual loans, but the depositor relies on the curator's choices and on the contracts that route the funds.

Loopscale does not publish a fee schedule in the sources behind this page. Borrowers and lenders should look for rate, origination and any protocol charges in the app before committing funds. Because loans are priced through an order book, the rate a borrower pays is set by the offer they accept, not by a single published rate card.

Network fees on Solana are usually small, but they are separate from any lending charges. Readers should compare the total cost of a loan, including network fees, against the yield on any vault.

Loopscale was exploited in April 2025 for about $5.8 million. One report said the attacker agreed to return the funds for a 10% bounty, and a later report described the team restoring loan repayment and top-up functions. Readers should check the current incident summary and any post-incident reports from the team before relying on the platform.

The sources behind this page do not state a list of smart contract audits, the audit firms involved or the dates of any audits. They also do not describe a regulatory licence or the jurisdiction the company is registered in. Treat these as unknown until the project publishes them.

DeFi lending carries smart contract risk, counterparty risk from borrowers and curators, and liquidation risk on collateral. Lending and borrowing crypto is restricted in some places, so check that it is legal where you live. Only use these products if you are 18 or older and can afford to lose the funds you put in.

Loopscale is for DeFi users who already hold assets on Solana, want a fixed rate on a loan, and are comfortable with smart contract and vault risk. It is less suited to people who need a published fee schedule, a regulated provider or a simple savings product with no exposure to protocol failures.
