Suiball, a Sui ecosystem project developing a native hardware wallet, will shut down and refund preorder customers in USDC. The project said it had spent years developing the product, completed hardware development and entered manufacturing, with initial shipments planned. The decision followed a recent series of attacks targeting crypto hardware wallets, leading the Sui Foundation to conclude that supporting the project posed excessive risks. About 80% of reservations were made on-chain and will be refunded in USDC to wallets holding the soulbound reservation NFT, with no user action required and distribution scheduled within one week. Credit-card customers will be emailed to provide a Sui wallet address before receiving USDC in a second distribution. Suiball will formally close after all refunds are completed.
