The Sandbox confirms SAND cross-chain bridge vulnerability: Base and BSC networks affected, cross-chain functionality has been suspended

The Sandbox official stated that the team has confirmed and fully controlled the recent SAND cross-chain bridge vulnerability incident, involving the Base and BNB Smart Chain (BSC) networks.

The official said that the impact of this incident is limited, involving less than 0.01% of the total supply of SAND tokens. SAND on Ethereum and Polygon is unaffected, and user wallets have not been compromised; related token holders and liquidity providers do not need to take action.

According to disclosures, the attacker minted uncollateralized SAND tokens on the Base and BSC networks through the vulnerability. Currently, The Sandbox has disabled the SAND cross-chain functionality on both networks, and SAND on Base and BSC has been isolated, temporarily unable to be transferred or exchanged.

The Sandbox reminds users not to buy, sell, or trade SAND on the Base and BSC networks, as liquidity on these networks has been affected.

The team stated that they have completed a snapshot before the incident and are formulating a compensation plan for affected liquidity pool (LP) users, while continuing to investigate the scope of the vulnerability's impact. A complete incident report and technical review will be released subsequently.
