The Sandbox: Officially opens the compensation claim for the vulnerability incident, which will last until midnight on the 23rd

According to official news, The Sandbox announced the official opening of SAND compensation claims. Users affected by the cross-chain contract vulnerability incident involving Base and BNB Smart Chain (BSC) networks on August 22, who held bridged SAND on the affected networks before the incident, can receive full compensation in SAND on the Ethereum network at a 1:1 ratio. Eligibility for compensation is based on the on-chain balance snapshot taken before the incident and is unrelated to the user's transactions, transfers, or holdings after the incident.

The Sandbox stated that eligibility for compensation is determined based on 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 BSC snapshot 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 process the compensation; however, users holding SAND in personal wallets will need to claim it themselves. The claim period is from September 8 to September 22, 24:00 (UTC+8). Claims only require a transaction initiated from the original wallet that held SAND at the time of the snapshot, without the need for token authorization, signing off-chain messages, or transferring to any address.
