The team behind the metaverse The Sandbox faced a serious security challenge, which, however, was quickly contained. I detected an attempt at unauthorized minting of a colossal volume of SAND tokens — 14.9 billion units, issued on the Base and BSC networks. For context: the total supply of the original asset on Ethereum is only 3 billion SAND, equivalent to approximately $140 million at current market prices. Thus, the attacker generated five times more tokens than exist legitimately, which could have crashed the market.
The project's developers responded promptly to the incident: they blocked cross-chain operations and isolated the suspicious tokens on the original blockchains where they were created. This prevented them from infiltrating the main Ethereum ecosystem, where the real SAND is traded. It is important to emphasize that user wallets were not affected — the damage impacted only 0.01% of the total SAND in circulation, indicating a targeted attack rather than a systemic infrastructure breach.
This case highlights the vulnerability of multichain architectures, where bridges and sidechains become entry points for manipulation. Although The Sandbox team acted professionally, investors should remember: such incidents are a reminder that liquidity on alternative networks is not always backed by real assets. I recommend monitoring the team's further reports to assess whether the root causes of the vulnerability have been addressed, not just its consequences.
