BlockBeats reports that on June 14th, the Echo Protocol, which focuses on Bitcoin liquidity re-staking and yield layers, announced that its wallet holding 2515.648579 uBTC (currently valued at over $266 million) has suffered a highly complex supply chain attack and has been maliciously compromised. The team has initiated an emergency investigation and will release an event review report as soon as possible. Currently, the collateral rate of the platform's treasury has fallen to 20%. To ensure system security, all withdrawal operations have been suspended since midnight Eastern Time. Echo Protocol stated that it is closely collaborating with auditing firms and security experts to handle this incident and will later announce a bounty program to encourage informants to assist in tracking the stolen assets.
