Cross-chain protocol Across says it is investigating a domain issue, warns users not to use the app for now
Cross-chain protocol Across posted on the X platform that it is currently investigating an issue with the Across domain. Until further notice, users should not access its app, connect their wallets, or sign any transactions or approvals in the app. It will publish further updates.
The statement was issued on November 10, 2026, and Across’s official account explicitly reminded users to pause all interactions with the app. At present, the protocol has not further explained the specific nature of the issue, whether it affects smart contracts or bridging operations, nor has it disclosed any losses or the scope of the impact. Across said it will continue to provide updates.

ABAB AI Insight
Across is a cross-chain bridge protocol that was launched around 2021 and focuses on improving the speed and cost of cross-chain transfers, having processed a large cumulative amount of cross-chain funds. The official statement only confirms that a “domain issue” is under investigation and takes precautionary measures to suspend frontend app interactions; it does not confirm whether domain hijacking, DNS tampering, frontend poisoning, or any other security incident has occurred.
Such statements are common in cases of suspected domain or frontend tampering, with the aim of preventing users from signing malicious transactions after connecting their wallets. Public information does not indicate that the smart contracts themselves or historical bridged funds have been affected, nor has there been any officially confirmed user fund loss. The protocol said it will continue to provide updates, indicating that the investigation is still ongoing.
Compared with security incidents at other cross-chain protocols, the publicly available information this time is more focused on the frontend/domain layer rather than directly pointing to a contract vulnerability. If users previously completed cross-chain operations through Across, they need to watch for whether subsequent official statements involve advice to revoke approvals.
This incident reminds cross-chain and DeFi users that frontend applications and domains are common attack surfaces. Before the official warning is clearly lifted, users should avoid accessing the relevant links and check wallet approvals. Key indicators are follow-up official updates, whether the specific issue type is confirmed, and whether there are reports of abnormal transactions from users.

An official cross-chain protocol warning users not to access the app or connect wallets usually points to frontend- or domain-related security concerns.
A statement saying it is “under investigation” and asking users to pause interactions does not mean that a contract or funds loss has already been confirmed.
Before the official warning is lifted, users should avoid interacting with the relevant app and pay attention to subsequent updates.
