When DeFi Lending Takes a Hit, Everyone Feels It

Last weekend’s attack on Kelp, a liquid restaking protocol, drained nearly $300 million from its vaults. The hackers exploited weak spots in how Kelp moved assets between blockchains, a process called cross-chain bridging. This move didn’t just hurt Kelp—it rippled across several lending platforms. Aave, Compound, and others froze trading of Kelp’s rsETH token to prevent losses from spreading. Experts say this wasn’t just one platform’s problem. It showed how risky it is to rely on shared collateral systems. When one token fails, many users face problems. Even well-known lending systems like Aave have had issues with this setup in the past. The lesson? DeFi platforms need to check tokens more carefully before letting them be used as collateral.Cross-chain bridges have become a big target for hackers. They’re a bridge between blockchains, but if they’re not secure, money can vanish fast. Some say these bridges should only be used when absolutely needed—like a last resort. Others point out that hacks like this aren’t new. Over $480 million was lost in the first three months of 2026 alone. The fallout from Kelp’s hack wasn’t limited to one place. At least nine different protocols had to take action, either freezing trades or limiting damage. The real challenge? Stopping problems from spreading before they explode. Security firms warn that the next hack could be even bigger if platforms don’t upgrade their defenses.
