Sui-native hardware wallet project Suiball is shutting down before its first production batch has reached customers, and all preorders will be refunded in USDC. The team announced the decision on X on November 11, 2026, saying it followed a reassessment of hardware wallet risk by the Sui Foundation, which suspended its backing of the project amid what Suiball described as a wave of recent hardware wallet attacks across the industry.

The closure is an unusually late-stage one. According to the team, Suiball completed years of development, produced a finished and working device, entered manufacturing, and was preparing to ship its first batch to supporters when the decision arrived. The project had set out to build a secure hardware device that was fully native to Sui — more than just a conventional hardware wallet. The episode also illustrates how industry-wide hardware wallet security concerns can reach past individual vendors to ecosystem-level support decisions, stopping a finished product at the edge of shipment.

Suiball shared the news and full refund details in the following announcement:

Suiball Refund Announcement

Thank you to everyone who supported us on this journey.

We set out to build a secure hardware device that was more than just a hardware wallet: one fully native to Sui. We did it. Suiball went into manufacturing, and we were ready to ship the first batch to our supporters.

After a wave of recent hardware wallet attacks across the industry, the Sui Foundation decided the risk of backing a hardware wallet project was too high right now. We understand that decision. Sui puts the security of its users and ecosystem first.

Still, after years of intense development and a finished, working product, it's hard to say that we have to close Suiball down. That's the nature of building an ambitious startup. We had the right intentions and the right capabilities, but this one wasn't meant to be.

How refunds work:

🔹 On-chain pre-orders (~80% of orders): You'll get your refund in USDC, airdropped straight to the wallet that holds your soul bound pre-order NFT. You don't need to do anything. This will happen within the next week.

🔹 Credit card pre-orders: You'll get an email asking for a Sui wallet address. Your refund will be airdropped there in USDC. We'll run a second airdrop once addresses come in.

🔒 All the personal information you gave us for device delivery, including your name, email, shipping address, and phone number, will be permanently deleted once refunds are complete. We won't keep any records.

⚠ We will never ask for your seed phrase, private key, or any payment. Only reply to emails from info@citadelwallet.io

Suiball will officially close once all refunds are complete. Thank you for believing in us.

A Finished Product That Never Shipped

The timing makes the closure particularly significant, as the product was far beyond the prototype phase. Suiball's website showcased a Sui-native device offering native support for Sui transactions and Move contracts, together with Bitcoin support, NFC, Bluetooth, and a secure element. Public product materials had positioned Suiball as the dedicated Sui wallet, featuring a touchscreen, an EAL6+ secure element, Bluetooth, USB-C, and NFC connectivity. Hardware wallets of this kind are built to keep users' private keys offline. The EAL6+ designation refers to a high assurance level under the Common Criteria international security certification framework.

The project had also adopted a deliberately conservative approach to security, previously holding back its initial shipment in order to complete additional audits before releasing devices to customers.

On-Chain Buyers to Receive Automatic USDC Refunds

Refund mechanics depend on how each customer originally paid. Suiball estimated that roughly 80% of preorders were made on-chain. Those buyers will receive refunds in USDC, a US dollar stablecoin, airdropped directly to the wallet holding their soulbound preorder NFT — a non-transferable token tied to a single wallet — with no action or claim process required. The team said this first round of refunds will be completed within the next week.

Customers who paid by credit card will instead receive an email asking them to provide a Sui wallet address. Once those addresses have been collected, Suiball will run a second USDC airdrop.

Suiball's preorder site had accepted only credit cards and USDC, so the two refund channels mirror the two payment methods used.

Team Warns Against Scams During Refund Process

As the refunds get underway, the team cautioned customers that it will never ask for seed phrases, private keys, or any form of payment during the process. Buyers were advised to reply only to emails sent from info@citadelwallet.io.

Customer Data to Be Permanently Deleted

Personal information collected for device delivery — including names, email addresses, shipping addresses, and phone numbers — will be permanently deleted once all refunds are complete, according to the announcement. The team said it will keep no records.

Official Closure to Follow Final Refunds

Suiball will officially shut down once every refund has been processed. The team did not claim that Suiball itself had suffered a breach, noting only that recent attacks had targeted third-party wallet applications. It attributed the shutdown to the broader risk assessment facing any hardware wallet product and to the withdrawal of the Sui Foundation's backing. From here, the announced milestones to watch are the first USDC airdrop due within the week, the second airdrop once card buyers have submitted wallet addresses, and the project's formal closure once every refund has landed.
