**[The Sandbox Officially Opens Compensation Claims for Vulnerability Incident, Available Until Midnight on the 23rd]** BlockBeats News, September 8: According to official announcements, The Sandbox has officially opened the claim process for SAND compensation. Users affected by the cross-chain contract vulnerability incident on the Base and BNB Smart Chain (BSC) networks that occurred on August 22, who held bridged SAND on the affected networks prior to the incident, can receive full compensation in Ethereum network SAND at a 1:1 ratio. Eligibility for compensation is based on the on-chain balance snapshot taken before the incident and is not related to any transactions, transfers, or holdings after the incident. The Sandbox stated that compensation eligibility is determined by the on-chain balance recorded before the contract was compromised. The snapshot for the Base network corresponds to block 50283188 at 23:42:03 UTC on August 21, 2026, while the snapshot for the BSC network corresponds to block 117322025 at 11:42:44 UTC on August 21, 2026. Users holding SAND on the Base or BSC networks through centralized exchanges do not need to take any action, as The Sandbox is coordinating with the relevant exchanges to handle the compensation process. However, users holding SAND through personal wallets will need to claim the compensation themselves. The claim period is from September 8 to 24:00 (UTC+8) on September 22. To claim, users only need to initiate a transaction from the original wallet that held SAND at the time of the snapshot. No token authorization, off-chain message signing, or transfers to any address are required. [Original Link]
