Cointelegraph’s report, published at 05:24 on Nov. 11, 2026 (UTC+8), said Across had warned users the previous Tuesday not to open its app or connect wallets while it investigated a potential security incident. Across is a cross-chain bridging protocol used to transfer digital assets between Ethereum and other blockchain networks.
In that Tuesday post on X, Across told users not to sign transactions or approvals until further notice. The warning did not say what the incident was, and it did not say whether the Across website had been compromised.
Cointelegraph then relayed three accounts posted on X and said it had not independently verified them.
- It attributed a claimed loss of $9,000 in USDC to X user bilm01, and its report shows Across responding to that claim.
- Another user reported losing 7,053 USDT0 across seven transactions on the Plasma blockchain.
- A third user said their wallet was drained after using the bridge several times and alleged that the website had been compromised.
Across asked those users for transaction details so it could investigate. Across Protocol did not immediately respond to Cointelegraph’s request for more details.
The only boundary Across stated in the material Cointelegraph published is the app itself: do not open it, do not connect a wallet, and do not sign a transaction or an approval while the investigation continues. The loss figures and the website-compromise allegation are user claims. Cointelegraph presented them as unverified.
