Suiball, a hardware wallet project built for the Sui ecosystem, announced it is shutting down and refunding all user pre-orders. The project had completed hardware development and entered the manufacturing phase, with initial shipments planned for early adopters. However, following multiple hardware wallet security breaches across the industry, the Sui Foundation determined that supporting hardware wallet projects posed excessive risk and withdrew its backing. Refunds will be distributed via USDC airdrops. Approximately 80% of pre-orders were placed on-chain; those users holding soulbound reservation NFTs will receive automatic refunds within one week with no action required. Credit card pre-order customers will receive an email requesting their Sui wallet address, after which a second round of USDC airdrops will follow. The project will officially close once all refunds are completed.
