The Sandbox blocks Base, BNB Chain bridging after vulnerability attack

The Sandbox said on X it identified a vulnerability related to its cross-chain bridge on Base and BNB Chain and blocked bridging on both networks. The attacker minted unbacked SAND on the two networks, with the impact estimated at under 0.01% of total SAND supply, the project said. The Sandbox added that SAND on Ethereum and Polygon, user wallets, and Ethereum-based SAND deposited as bridge collateral were not affected. The project is preparing a compensation plan for affected liquidity pool users and urged users not to trade SAND on Base or BNB Chain.
