Crypto Bridge Protocol CrossCurve Exploit

Crypto bridge CrossCurve has told users to pause interacting with its protocol while it conducts an investigation into a smart contract breach.

Crypto protocol CrossCurve said its cross-chain bridge has been attacked, with reports that $3 million has stolen across multiple networks.

CrossCurve posted to X late on Sunday that its bridge was โ€œunder attack, involving the exploitation of a vulnerability in one of the smart contracts used.โ€

โ€œPlease pause all interactions with CrossCurve while the investigation is ongoing,โ€ it added.

The blockchain security-focused X account Defimon Alerts said CrossCurve was exploited for around $3 million โ€œon several networks.โ€

It added that one of CrossCurveโ€™s smart contracts allowed anyone to spoof a message to bypass validation and unlock tokens.

โ€œAnyone could call expressExecute on ReceiverAxelar contract with a spoofed cross-chain message, bypassing gateway validation and triggering unlock on PortalV2,โ€ Defimon Alerts said.

Curve Finance, which has partnered with CrossCurve, posted on X that users who allocated to CrossCurve pools โ€œmay wish to review their positions and consider removing those votes.โ€
