Kelp DAO, which suffered a $292 million hack in April, announced via X: "We detected potential suspicious activity from a specific address (starting with 0xc70f) that received rsETH a few hours ago. As a precautionary measure, we have applied a temporary freeze to this address for 24 hours, during which deposits and withdrawals of rsETH from this wallet will be restricted. Currently, the Kelp DAO contract is secure, and rsETH is fully collateralized. All operations, including minting, withdrawals, and external protocol integrations, are proceeding normally, and no separate action is required from users."
