A periphery contract of DeFi platform Aave was hacked for $56,000 across Ethereum, Arbitrum, Polygon, Optimism, and Avalanche networks. The affected ParaSwapRepayAdapter contract, not part of Aave's core protocol, held leftover tokens from swap slippage. Aave confirmed no user funds were at risk, likening the incident to raiding a "tip jar." The hack sparked renewed tensions between Aave and Euler Finance, with founders exchanging criticisms over past security incidents and protocol management.
