A serious incident occurred in The Sandbox metaverse ecosystem that could have led to catastrophic consequences for the market. I managed to determine that an unknown attacker exploited a vulnerability in the project's cross-chain infrastructure and minted 14.9 billion unbacked SAND tokens on the Base and BSC networks. For comparison: the total supply of the original asset on Ethereum is only 3 billion SAND, which is equivalent to approximately $140 million at current quotes.
Immediate response and threat isolation
The Sandbox team acted promptly. Developers fully blocked cross-chain operations and isolated the compromised tokens on their original blockchains, preventing their movement to other networks. Critically, user wallets were not affected—the damage impacted only 0.01% of the total SAND in circulation. This indicates that the attack was aimed specifically at the infrastructure level, not at end holders of assets.
Situation analysis
Such incidents highlight the systemic risks associated with multichain architecture. Even a minor error in the logic of bridge smart contracts can lead to uncontrolled minting, which would instantly collapse trust in the project. However, it is worth noting that the rapid localization and blocking of assets is a positive signal for the market. The Sandbox demonstrated maturity in crisis management, which could strengthen its position in the long term.
Nevertheless, investors should remain vigilant. The incident shows that even major metaverses with years of history are not immune to technical failures. In the coming weeks, I will closely monitor the development of the situation and the team's response to community requests for details about the vulnerability. Transparency in disclosing technical details will be a key factor in restoring full trust in the project.
