The Sandbox says it contained a bridge exploit that minted unbacked SAND on Base and BNB Smart Chain, as Upbit and Bithumb froze SAND deposits and withdrawals.

Over 500 million SAND tokens were minted through an infinite mint exploit on The Sandbox's Base network deployment, threatening major supply

The Sandbox disabled bridging on affected networks to isolate tokens and warned users not to trade SAND on Base and BNB, citing impact under 0.01% of supply.
