Sandbox Security Breach Alert: 500M+ SAND Minted On Base

A suspected Sandbox Security Breach on the Base network has put the metaverse project at the center of crypto news today , after on-chain records showed an attacker gaining minting control over the SAND token.

According to blockchain research firm WuBlockchain , more than 500 million SAND had been created without authorization as of August 22, with the activity still ongoing at the time of reporting.

WuBlockchain also covered this development on X, and the attacker wallet can be tracked directly on BaseScan .

An unknown actor obtained token minting permissions on the contract deployed on Base, Coinbase's layer-2 network .

This SAND minting exploit allowed new tokens to be created outside the project's normal supply schedule, meaning the SAND token was minted illegally, and figures kept climbing without protocol approval.

The SAND, a voxel-based metaverse platform, is a subsidiary of Animoca Brands and raised $93 million in a 2021 funding round.

As one of the top stories in SAND crypto news , this Animoca Brands hack stands out because the exploit involves direct token creation rather than a wallet drain, unlike typical custodial hacks.

Analysts tracking the wallet flagged that this metaverse hack could pressure circulating supply if the minted tokens reach open markets, marking one of the more serious cases of a Sandbox Security Breach on a major L2 network this year.

Tokens minted (unauthorized)

South Korea's two largest exchanges moved quickly once signs of the token hack surfaced:

Upbit issued a formal Upbit SAND warning, flagging the token for a possible security issue and cautioning users heightened price volatility. Upbit said it identified the anomaly on August 22.

Bithumb went further, confirming Bithumb suspended deposit and withdrawal functions as a precaution while the situation was assessed.

Both platforms are known for reacting fast to on-chain anomalies, having previously restricted trading on other tokens during past incidents.

Neither exchange has stated whether SAND will be delisted, and both actions are currently framed as temporary safety measures tied to the unfolding Sandbox Security Breach rather than confirmed findings against the project.

Not officially, at least not yet. The team has not issued a public statement confirming or denying the exploit as of this report.

What is verifiable is the on-chain data itself: BaseScan shows large mint-related transactions tied to the flagged contract, which supports the community's concern even without an official confirmation from Animoca Brands or The Sandbox.

Traders should treat this as a developing situation. The Sandbox Security Breach narrative is currently built on on-chain evidence and exchange precautions, not a verified incident report from the project.

Following the reports, saw a sharp move lower, with trading activity spiking well above normal levels as the news spread across social platforms.

A sudden jump in unconfirmed supply tends to weigh on price sentiment, and that appears to be playing out here, though figures on the exact price drop vary across trackers and have not been independently confirmed by an official source.

Market analysts note that minting-permission exploits rank among the more severe smart contract risks since they affect token economics directly rather than draining a single wallet.

Until The Sandbox or Animoca Brands issues an official post-mortem, the scale of damage and any remediation plan, such as a contract pause or token migration, remain unclear.

Exchange caution measures from Upbit and Bithumb are typically standard risk controls during unresolved incidents, not a judgment on the project's long-term viability, though how quickly the team addresses this Sandbox Security Breach will likely shape trader confidence.

The details of this suspected exploit are still developing and unconfirmed by The Sandbox's official channels. Readers should verify updates directly from Animoca Brands, The Sandbox, Upbit, and Bithumb before making any trading decisions involving.
