According to CoinMeta, Wu said that he learned that the SUI ecological hardware wallet project suiball has announced its closure and will refund all pre-order users. suiball stated that its hardware devices have been developed and have entered the manufacturing phase, with plans to deliver them to the first batch of users. However, due to several recent hardware wallet attacks in the industry, SUI Foundation believes that the risks of continuing to support the hardware wallet project are too high, and therefore has decided to stop supporting it. Approximately 80% of the pre-order orders were completed on-chain, and relevant users will automatically receive their refunds within a week. Pre-order users who made payments via credit card will need to provide their SUI wallet addresses to receive the refunds. The project will be officially closed after all refunds have been made.
