⚠️CrossCurve $3 Million Theft Analysis
👉On the evening of February 1, 2026, the CrossCurve (@crosscurvefi @ceo_eywa) cross-chain bridge was attacked, resulting in the theft of approximately $3 million. The vulnerability primarily stemmed from the fact that the `expressExecute` method of the CrossCurve Axelar receiver contract allowed anyone to call it. Attackers used this to trick the contract into believing that cross-chain funds had arrived, thus allowing the CrossCurve PortalV2 contract to unlock the assets.
👉The attackers stole a total of $3 million from the ETH and ARB chains, using Jumper Exchange for cross-chain operations. Most of the funds remain untouched. Below is a detailed analysis diagram and the vulnerable code.
