Summer.fi Announces Shutdown Following Protocol Attack, Frontend to Remain Available Until August 31

Odaily reported that Lazy Summer Protocol was attacked on July 6th, and the Summer.fi team has announced the closure of Summer.fi and its parent company, Labs. The attacker manipulated the share prices of two USDC Vaults on the Ethereum mainnet, stealing approximately $6.04 million in deposits in a single transaction, resulting in losses to both the protocol and the team's own funds, depleting operational capital. Against the backdrop of overall pressure on DeFi following the Stream Finance incident in October 2025, the team stated that no feasible restructuring path remains and will maintain the Summer.fi frontend available until August 31st.
