Solana’s Loopscale Halts Lending After $5.8M Exploit

Loopscale, a DeFi protocol on Solana, halted lending activities after experiencing a $5.8 million exploit involving USDC and SOL vaults on April 26, 2025.

The incident highlights ongoing vulnerabilities in DeFi, spurring calls for increased transparency and security measures from both the community and institutional backers.

Vulnerability in Pricing Function Leads to Exploit

A vulnerability in the RateX PT token pricing function led to the unauthorized draining of approximately 5.7 million USDC and 1,200 SOL. Mary Gooneratne, co-founder of Loopscale, is spearheading the investigation and recovery efforts, focusing on affected vaults without impacting borrowers or loopers.

“The incident only affected SOL and USDC Genesis vault depositors, not borrowers or loopers, and promised a technical post-mortem and detailed withdrawal plan soon.”

12% Drop in Total Value Locked After Breach

The exploit caused a 12% reduction in Loopscale’s total value locked, with immediate freezing of market functions. Confidence in Solana’s DeFi ecosystem faced a blow, as institutional backers, including Solana Labs and Coinbase Ventures, engage in ongoing recovery dialogues.

Recalling Previous Solana Exploits and Lessons

The event recalls previous Solana exploits similar to the Slope Wallet hack, stressing systemic DeFi vulnerabilities. Such incidents typically result in protocol-native asset price drops and TVL contractions. Recovery paths will depend on Loopscale’s transparency and infrastructure enhancements.
