Following a series of cold wallet incidents, Sui has decided to exit this space. @suiballO, the Sui ecosystem’s cold wallet project, has just announced its closure and is issuing full refunds to all pre-order customers. Notably, the device had already been fully developed, entered production, and was set to ship its first batch. After a string of recent cold wallet attacks, the Sui Foundation determined the risks were too high and decided to cease support. The crisis stemmed from CryptoBilis, a distributor in Southeast Asia, where Ledger discovered that wallets sold through this channel had been tampered with—hidden chips were installed to capture screen data and transmit seed phrases to hackers, resulting in estimated losses of $93 million. Subsequently, Trezor also received reports of similar tampering on wallets purchased through the same distributor.
