Across Protocol warns users to pause using the app amid multiple reports of wallet theft

Across Protocol is a cross-chain bridging solution enabling users to transfer digital assets between Ethereum and other blockchain networks. On Tuesday, the protocol issued a security alert on X, announcing an ongoing investigation into a potential security incident of undetermined nature. It urgently advised users to stop accessing its application, refrain from connecting wallets, avoid signing any transactions, and not grant any permissions. As of now, Across has not confirmed whether its official website was compromised, nor has it disclosed specific details about the incident. Several users have reported fund losses on X: one user claimed a loss of $9,000 in USDC; another reported losing 7,053 USDT across seven transactions on the Plasma network; and a third stated their wallet balance dropped to zero after multiple uses of the bridge and alleged the website had been hacked. Across has reached out to these users, requesting relevant transaction details to support its investigation.
