Phantom wallet will discontinue support for the Sui blockchain on September 24, 2026, ending users’ ability to manage Sui-based assets directly through the wallet’s interface. After the deadline, users will no longer be able to view, send, swap, or interact with Sui assets through Phantom.
The decision marks a change for users who currently rely on Phantom to manage assets connected to the Sui network. While access through the Phantom interface will end, the assets themselves will remain recorded on the Sui blockchain and will not be removed from users’ control.
According to the information provided, Phantom has not disclosed why it plans to end support for Sui. The company has, however, indicated that users’ assets will remain secure and under their control. Because blockchain assets are recorded onchain rather than stored directly by a wallet provider, users can continue accessing them through another compatible wallet using their recovery credentials.
Phantom’s Sui support will end on September 24, requiring users who want continued access through a wallet interface to migrate their assets or import their recovery credentials into a compatible Sui wallet before the deadline.
Sui Assets Will Remain on the Blockchain
The end of Phantom’s support does not mean that users will lose ownership of their Sui assets. Instead, the change affects the wallet interface and its ability to interact with the Sui network.
Users who hold Sui assets through Phantom can retain control as long as they have access to the appropriate recovery phrase or credentials. Those credentials can be used with another wallet that supports the Sui blockchain, allowing users to regain access to their assets and continue managing them onchain.
Users have therefore been advised to complete any necessary migration before September 24. Those who prefer to continue using a wallet interface after the deadline can import their recovery phrase into another compatible wallet, including Slush, according to the information provided.
The transition highlights the importance of maintaining secure access to wallet recovery credentials. Users should ensure that their recovery phrases are stored safely and never shared with third parties, particularly during a migration period when phishing attempts or fraudulent support accounts could emerge.
Fee Waiver Available for SUI Conversion
Phantom has also introduced a temporary fee waiver for users swapping native SUI into wrapped SUI on Solana before the support deadline. The waiver is intended to make the conversion process easier for users who want to move their assets into the Solana ecosystem.
The fee waiver does not cover blockchain network fees. Users conducting the swap will therefore still be responsible for applicable network costs associated with processing the transaction.
The availability of the waiver provides users with another option before Sui support is removed, particularly for those who already use Solana-based assets and want to continue managing their holdings through Phantom.
Phantom and Sui have decided to end Sui support on Phantom on September 24, and leave open the opportunity to explore other collaborations in the future.
Your funds remain safe and fully under your control. Before 9/24, you can move your wallet to another app that supports Sui,…

Migration Deadline Approaches
As the September deadline approaches, Sui users should determine how they intend to manage their assets after Phantom ends support. Users choosing another compatible wallet can use their recovery credentials to restore access, while those opting for the Solana conversion route can take advantage of Phantom’s temporary swap-fee waiver.
The change affects access through Phantom rather than ownership of Sui assets, meaning users who securely retain their recovery credentials can continue accessing their holdings through compatible wallets after the deadline.
As per reports, Phantom has not provided a specific explanation for the decision to discontinue Sui support. The company’s assurance that assets remain under users’ control means the primary action required is migration or conversion rather than asset recovery.
With the September 24 deadline fixed, users are encouraged to avoid waiting until the final day to move their holdings. Completing the transition early can provide additional time to verify wallet compatibility, secure recovery credentials, and resolve any transaction issues before Phantom’s Sui functionality is removed.
