The Sandbox Opens SAND Compensation Claims for the August 22 Cross-Chain Vulnerability

Huo Xing Finance reports that, according to official announcements, The Sandbox has officially opened the claim period for SAND compensation. Users affected by the cross-chain contract vulnerability incident on the Base and BNB Smart Chain (BSC) networks on August 22, who held bridged SAND on the affected networks prior to the incident, are eligible for full compensation of SAND on the Ethereum network at a 1:1 ratio. Eligibility for compensation is determined solely by on-chain balance snapshots taken before the incident and is unrelated to any transactions, transfers, or holdings after the event. The Sandbox states that compensation eligibility is based on on-chain balances recorded prior to the contract compromise: the Base network snapshot corresponds to block 50,283,188 at 23:42:03 UTC on August 21, 2026, and the BSC snapshot corresponds to block 117,322,025 at 11:42:44 UTC on August 21, 2026. Users holding SAND on Base or BSC via centralized exchanges need take no action, as The Sandbox is coordinating with relevant exchanges to handle compensation; users holding SAND in personal wallets must claim compensation themselves. The claim period runs from September 8 to September 22, 24:00 (UTC+8). Claiming requires only a single transaction initiated from the original wallet that held SAND at the time of the snapshot—no token approval, no off-chain signature, and no transfer to any address is required.
