SUI Phantom will stop supporting the Sui blockchain on September 24.
Phantom, the popular self-managed crypto wallet, announced that it will end its support for the Sui blockchain on September 24, when Sui-related balance viewing, sending, redemption and decentralized application (dapp) connection functions in the wallet will be removed. If you own Sui in Phantom, this change will directly affect how you view and use these assets.
What content has Phantom adjusted for Sui users?
Phantom posted a document on the X platform confirming that it will turn off the Sui support function in its wallet on September 24. From that date, Sui will no longer appear in apps as a supported network. The removal involves four functions: balance viewing, sending, redemption and dapp connection, all for the Sui network. Simply put, dapp connections allow wallets to interact with decentralized applications running on the blockchain rather than applications on company servers. These four Sui-related functions will fail at the same time.
What impact will this change have on existing Phantom Sui users?
Losing the balance view feature means Phantom will no longer display your Sui positions in the app. These tokens were originally a web feature of the wallet interface, but you will no longer be able to see them directly. Losing sending and redemption capabilities means that you can no longer transfer out or trade Sui through Phantom. Sending means transferring tokens to another address, and redemption means exchanging one token for another. Losing dapp connectivity means Sui-based apps will no longer be able to connect to Phantom. Anyone using the Sui app through the wallet will need to find other ways to connect.
Why is it important for Phantom to withdraw from Sui support?
This is not just a small adjustment in functionality. Phantom removes four independent Sui functions at the interface level at one time, rather than adjusting a single setting. The importance is that one wallet withdraws interface support for the entire blockchain network. This fallback operation forces affected users to migrate Sui-related operations to other wallets before the deadline. Practical advice: If you hold Sui in Phantom, please keep an eye on September 24 and plan in advance where your subsequent Sui activities will be placed. Safety-conscious holders may also want to focus on broader wallet security trends when selecting new wallets, such as the U.S. Treasury Department's push to include digital assets in quantum security plans. For newcomers to cryptocurrency, you can observe how the wallet handles multi-chain support-a factor often mentioned in mainstream cryptocurrency inventories.
Based on available information, Phantom did not provide specific reasons for terminating Sui support. What has been confirmed so far is the deadline and the specific features that will be removed.
