Upbit and Bithumb Place SAND Under Caution Following Bridge Exploit

The exchanges initiated the restrictive measures after detecting abnormal activity linked to a vulnerability in the project's bridge infrastructure. While The Sandbox confirmed that the exploit was contained and that assets held on Ethereum and Polygon remained secure, the lack of a finalized resolution prompted both platforms to suspend deposits and withdrawals. Trading remains active, but the token is now subject to heightened oversight to protect users from potential price volatility and security risks.

Upbit has scheduled a review period running through early October to determine the token's future on its platform. The exchange may choose to lift the warning, extend the review, or terminate trading support entirely if the project fails to satisfy security requirements. Bithumb is following a similar timeline, with a final decision expected during the first week of October. The Sandbox team is currently preparing a compensation plan for affected liquidity providers and expects to release a full technical post-mortem once their internal investigation concludes.
