The team behind the metaverse The Sandbox has faced a serious challenge: during routine monitoring of the Base and BSC networks, anomalous activity was detected related to the unauthorized issuance of SAND tokens. The attacker managed to generate a colossal volume — 14.9 billion unbacked assets, which is many times greater than the legitimate supply of the original token on Ethereum, which amounts to just 3 billion SAND (approximately $140 million at the current exchange rate).
Immediate response and threat isolation
The project's developers acted swiftly: cross-chain bridges and related operations were immediately blocked, and suspicious tokens were isolated in their original networks. This prevented the spread of fake assets to other blockchains and minimized potential damage to the ecosystem.
It is important to emphasize that user wallets were not affected. The incident impacted only 0.01% of the total SAND in circulation, indicating the targeted nature of the attack. Nevertheless, the very fact of such a vulnerability raises questions about the security of cross-chain infrastructure as a whole — such incidents serve as a reminder that even mature projects with multi-million-dollar capitalization remain vulnerable to new attack vectors.
At the moment, The Sandbox team continues its investigation, and users are advised to monitor the project's official channels for updates. This case is another signal to the industry about the need to implement stricter mechanisms for verifying issuance and auditing smart contracts at all levels of bridges.
My analysis: Although the scale of the issuance looks threatening, the rapid containment demonstrates the team's maturity in crisis management. However, investors should consider that such incidents may temporarily pressure the price of SAND, even if the project's fundamental indicators remain stable. In the long term, this is rather a positive signal — the vulnerability was found and closed before it could be exploited to its full extent.
