The Sandbox contained a cross-chain exploit minting unbacked SAND; impact under 0.01% of total supply.

The Sandbox identified and contained a vulnerability in its cross-chain bridge on Base and BNB Smart Chain that allowed an attacker to mint unbacked SAND tokens. The incident affected less than 0.01% of the total 3 billion SAND supply, with no user wallets compromised and Ethereum and Polygon tokens remaining secure. Transfers on the affected networks were disabled, and liquidity providers before the attack will be compensated. Exchanges like Upbit and Bithumb halted SAND deposits and withdrawals as a precaution while the investigation continues.
