On Aug 22, 2026, The Sandbox disabled cross-chain bridging to and from Base and BNB Smart Chain after an exploit minted unbacked SAND tokens. On-chain monitors led by PeckShield flagged roughly 14.9 billion SAND created across attacker addresses, about $49 billion in face value at the time. The project said the affected amount stayed under 0.01% of supply and told users not to use SAND on Base and BNB. SAND fell roughly 10% intraday. South Korean exchanges Upbit and Bithumb froze SAND transfers.
