- A complete of $71 million stays frozen by the Arbitrum Safety Council. A court docket listening to in New York remains to be pending.
The hacker chargeable for the Kelp DAO exploit of $293 million managed to launder roughly $220 million in stolen funds in simply six weeks, in line with knowledge from Arkham and onchain analysts. The pockets linked to the attacker holds simply $1.7 million in traceable funds, drastically decreasing the possibilities of recovering the non-frozen property.

Kelp DAO itself additionally migrated its rsETH token to Chainlink CCIP, shifting away from the LayerZero-based bridge it attributed the exploited vulnerability to.
LayerZero, for its half, clarified that the exploit originated in a single level of failure in Kelp DAO’s implementation, which relied on a single LayerZero DVN as the only verified route, regardless of warnings issued towards that configuration.
