The Sandbox announced 1:1 compensation on Ethereum for users affected by a bridge exploit, with claims opening within two weeks based on a pre-attack onchain snapshot, the company said on August 27.
The compensation structure covers SAND token holders on Base and BNB Chain at two fixed block heights: 50,283,176 on Base and 117,321,965 on BSC. Users will receive one Ethereum-based SAND token for each SAND held at those heights. The snapshot timing places the claim baseline before the attack occurred.
The bridge exploit in August drained approximately 675,000 SAND tokens across multiple chains, according to the company's post-incident review. The attack exposed a vulnerability in The Sandbox's cross-chain bridge architecture that allowed unauthorized token minting on Base and BSC while draining legitimate holdings. The incident marked one of the larger bridge exploits in 2026 by token volume.
The Sandbox said it has contained the unbacked token supply created during the attack. The company did not disclose the total compensation amount in absolute terms but framed the 1:1 replacement as restoring holdings to pre-attack levels for affected users. Recovery of user funds has become a standard expectation in the metaverse and gaming token ecosystems after similar incidents at Ronin and Axie in prior years.
The two-week window gives The Sandbox time to finalize claim infrastructure and verification systems. The company has not specified a claim duration or hard deadline for compensation distribution once the window opens. Users will need to verify ownership through wallet signatures or other proof-of-holdings mechanisms, though The Sandbox has not detailed the exact process.
Bridge exploits have persisted as a category of blockchain risk despite heightened security audits. The Sandbox's incident follows a pattern where cross-chain protocols become targets when custody mechanics are complex or when upgrades introduce temporary vulnerabilities. The company operates a metaverse platform where SAND serves as both governance and in-game currency, making widespread token loss a material disruption to user experience and platform economics.
The compensation plan addresses the most direct victims of the drain but does not recover funds for any secondary market trading or liquidation losses that may have occurred during or after the attack. The Sandbox's commitment to 1:1 compensation on a single chain (Ethereum) rather than across all affected chains leaves open the question of how users on Base and BSC will move claimed tokens if they prefer to hold them on those networks. If The Sandbox does not clarify the multi-chain bridge status before claims open, users may face friction moving compensation into their preferred chains.
