Bitget, the world's sixth-largest crypto exchange, disclosed on Thursday that roughly $352 million in digital assets was affected in a suspected hack — one of the more significant security incidents the industry has seen this year.
Here's how it unfolded: independent blockchain researchers first flagged unusual wallet activity, with early estimates ranging from $170 million to $183 million in moved assets, including ETH, BNB, AVAX, and USDT0 spread across three hot wallets and one cold wallet on multiple chains. Bitget CEO Gracy Chen confirmed the incident shortly after, stating that the exchange detected unauthorized transfers at 18:31 UTC and immediately activated emergency response protocols. The final figure landed at approximately $351.6 million. Chen emphasized that Bitget's cold wallets — where the majority of user funds are typically held — remained fully secure, and that the exchange's three-tier wallet architecture contained the breach to a portion of its hot and warm wallet layers. The company also pointed to a user protection fund holding over $464 million as a backstop. Withdrawals have been temporarily paused while the security review continues, though deposits and trading remain active.
Why does this matter? Hot-wallet breaches remain one of the most persistent vulnerabilities for centralized exchanges, since these wallets need to stay internet-connected to process transactions quickly — a trade-off between convenience and exposure. An incident at this scale, on a top-six exchange, tends to reignite broader conversations around custody practices, wallet architecture, and how much of an exchange's holdings should sit in cold storage versus hot wallets at any given time. How Bitget handles reimbursement and transparency in its incident report over the coming days will likely shape how much lasting impact this has on user trust — something the industry has weathered before, with mixed outcomes depending on the response.
Whether the promised protection fund fully covers the loss, and what the final incident report reveals about how the breach occurred, are still open questions.
Does an exchange's response after a hack matter more to trust than the fact that the hack happened at all? 🤔
