The Sandbox announced on August 28, 2026, that it will fully reimburse users affected by a $700,000 exploit on its cross-chain bridge. Eligible token holders on Base and BNB Chain will receive Ethereum-based SAND tokens directly from the project’s treasury. The repayment will be made on a 1:1 basis, ensuring affected users recover the full value of their lost assets. Claims are expected to open in the coming weeks following verification procedures. The exploit occurred when attackers manipulated a vulnerability in the bridge contract, allowing unauthorized minting and withdrawal of SAND tokens across chains. The Sandbox team detected the anomaly quickly and halted further transactions to prevent additional losses. While the breach did not affect the core game or metaverse functionality, it raised concerns about cross-chain security in decentralized applications.

The company emphasized that user funds held in its treasury remain secure and sufficient to cover the repayment. How the Repayment Process Will Work Affected users will need to verify their holdings on Base and BNB Chain through an official claims portal. The Sandbox will use snapshot data taken before the exploit to determine eligibility and payout amounts. Once verified, users will receive SAND tokens on the Ethereum mainnet, which can be used within the platform or transferred to other wallets. The project stated that no action is required from users who held SAND on Ethereum or other unaffected chains during the incident. What Measures Are Being Taken to Prevent Future Incidents? In response to the exploit, The Sandbox has engaged third-party security firms to conduct a full audit of its bridge infrastructure. The team is implementing upgraded validation checks and multi-signature controls to strengthen transaction integrity.

Additionally, the company plans to introduce a bug bounty program focused specifically on cross-chain components. These steps aim to restore user confidence and improve resilience against similar threats in the evolving DeFi landscape. Frequently Asked Questions Who is eligible for repayment? Only users who held SAND on Base or BNB Chain at the time of the exploit and can verify their holdings via the official snapshot are eligible for reimbursement. Will users need to pay fees to claim their tokens? No, The Sandbox will cover all transaction costs associated with the repayment process; users will not incur any fees to receive their SAND tokens. Is the Sandbox metaverse or gameplay affected by this incident? No, the exploit was isolated to the bridge contract and did not impact the core platform, user avatars, land holdings, or in-game assets.
