Suiball, the hardware wallet built specifically for the Sui blockchain, is closing down before a single unit reached a customer’s hands.
The project halted its launch and says it will refund on-chain pre-orders in USDC within a week. For a device that had finished development and entered manufacturing, that is a remarkably late exit.
The announcement came on November 11, 2026. It closes a roughly year-long arc that began with a splashy debut and ended with a security reckoning that wasn’t even about Suiball itself.
What happened to Suiball
Suiball was developed by Citadel Wallet and pitched as a hardware wallet native to the Sui network. The core reason for the shutdown is that the Sui Foundation withdrew its support.
The foundation cited heightened security risks facing hardware wallets. Those concerns followed a series of security breaches across the broader industry.
The notable detail is what the foundation did not say. No specific vulnerabilities were identified in Suiball’s own system.
In October 2026, Suiball paused shipments so it could undergo additional security audits recommended by Mysten Labs and Sui Network teams.
A month later, the pause became permanent.
How the refunds will work
Suiball says customers will be paid back in USDC, the stablecoin pegged to the US dollar. The mechanics depend on how each buyer placed their order.

Approximately 80% of pre-orders were made on-chain using soulbound NFTs. Those buyers are slated to receive refunds automatically.
Soulbound NFTs are tokens that can’t be transferred once issued. Think of them as a receipt glued permanently to your wallet, which conveniently tells the company exactly where to send your money back.
The remaining customers paid by credit card. They will receive instructions on how to submit a Sui wallet address so their refund can be processed.
The company also says it plans to delete all personal customer data it collected once refunds are processed.
The device that almost was
Suiball first launched at SuiFest in October 2025. The pitch centered on deep integration with the Sui network rather than treating Sui as one more chain in a long dropdown menu.
It wasn’t Sui-only, though. The wallet also included support for Bitcoin.
On the hardware side, Suiball featured an EAL6+ secure element and a touchscreen display. A secure element is a dedicated chip designed to store private keys in isolation, so they never touch the parts of a device that are easier to attack.
The EAL rating refers to a certification scale for security evaluation. Higher numbers indicate more rigorous testing, and EAL6+ sits near the top of that ladder.
The project had completed development and begun manufacturing before shipments were frozen.
What this means for Sui and hardware wallets
The most immediate takeaway is about ecosystem dependence. Suiball’s fate was tied closely to the Sui Foundation, and once the foundation stepped back, the project didn’t continue independently.
The Sui Foundation pulled support without pointing to a flaw in Suiball, based instead on the broader threat climate for hardware wallets.
For pre-order customers, the outcome is about as orderly as a cancellation gets. Refunds are promised in a dollar-pegged stablecoin, most on-chain buyers don’t need to take any action, and personal data is slated for deletion.
The company has committed to paying on-chain buyers within a week, and credit card customers will need to follow the submission process to get theirs.
