The Sandbox has officially opened compensation claims for its vulnerability incident, with the application window remaining open until 00:00 on the 23rd.

According to an official announcement, The Sandbox has officially opened SAND compensation claims. Users affected by the SAND cross-chain contract vulnerability incident on Base and BNB Smart Chain (BSC) on August 22 will receive full SAND compensation on the Ethereum network at a 1:1 ratio, provided they held bridged SAND on the affected networks before the incident. Eligibility is based on on-chain balance snapshots taken prior to the event and is independent of any transactions, transfers, or holdings users made after the incident. The Sandbox stated that compensation eligibility is determined by on-chain balances recorded before the contract exploit. The Base network snapshot corresponds to Block 50283188 at 23:42:03 UTC on August 21, 2026, while the BSC snapshot is Block 117322025 at 11:42:44 UTC on the same date. Users holding SAND on Base or BSC via centralized exchanges do not need to take any action, as The Sandbox is coordinating with relevant platforms to process compensation. Those holding SAND in personal wallets must submit claims on their own. The claim period runs from September 8 to 24:00 UTC+8 on September 22. To file a claim, users only need to initiate a single transaction from the original wallet that held SAND at the snapshot time—no token authorization, off-chain message signing, or transfers to any addresses are required.
