Sui hardware wallet Suiball shuts down: no action needed for on-chain reservations; credit card reservations should only reply to the official email

At around 9:00 this morning (Hong Kong time), Sui ecosystem hardware wallet Suiball officially announced that it was shutting down and would refund USDC to all customers who preordered. The team said the device had entered manufacturing and was originally scheduled to ship to its first supporters. But according to the team, following a series of hardware wallet attacks in the industry recently, the Sui Foundation believed that continuing to support this kind of project posed too much risk at this time. This is Suiball’s unilateral account; as of the time of this report, the Sui Foundation had not publicly responded. This is not a theft or an exchange suspending deposits and withdrawals.

Who is affected: people who preordered. The team said about 80% of reservations were made on-chain. USDC will be airdropped to the wallets holding the soulbound reservation NFTs; no action is needed, and the funds are expected to arrive within a week. People who reserved with a credit card will receive an email asking them to provide a Sui wallet address, after which a second airdrop will be made. The team explicitly stated: it will not ask for seed phrases, private keys, or any payment. Only reply to emails from info@citadelwallet.io. Once all refunds are complete, the project will delete the personal information of customers who provided it and officially shut down.

First check which type of reservation you made, and confirm that any credit card email came from this official address. Don’t click unfamiliar links claiming to offer refunds or asking you to connect a wallet or sign a transaction.

Did you preorder on-chain or by credit card?

This is not investment advice.
