Renegade, an on-chain dark pool, reported that its older V1 Arbitrum deployment was exploited, resulting in a loss of approximately $209,000. A white hat hacker has returned about $190,000, and all affected users will receive full compensation. Renegade confirmed that the issue is isolated to the V1 Arbitrum deployment, with other deployments, including V1 Base, V2 Arbitrum, and V2 Base, remaining secure. All infrastructure supporting V1 Arbitrum transactions has been suspended, and no further funds are at risk.
