Phantom, the cryptocurrency 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. Once the deadline passes, users will no longer be able to view, send, swap, or otherwise interact with Sui assets inside Phantom.

The decision marks a change for users who currently rely on Phantom — available at phantom.com — to manage assets connected to the Sui network. Phantom first built its user base around Solana before expanding multichain support to additional networks, and its Sui integration was part of that broader push, so the upcoming removal narrows the set of chains the wallet supports. 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.

Phantom disclosed the change in a post on X on August 24, 2026:

"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,…"

According to the information provided, Phantom has not disclosed why it plans to end support for Sui, beyond the statement that the two parties are leaving open the opportunity to explore other collaborations in the future. 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, including Slush, a wallet built for the Sui ecosystem, according to the information provided, 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 rather than leaving their holdings without an interface for management.

The transition also 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, where Phantom continues to operate.

The fee waiver does not cover blockchain network fees. Users conducting the swap will therefore still be responsible for the applicable network costs associated with processing the transaction.

The availability of the waiver gives users 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 after the Sui functionality is switched off.

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. Wallet compatibility can be confirmed through official Sui ecosystem listings and wallet providers' own documentation before any transfer is initiated.

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, and the company's assurance that assets remain under users' control means the primary action required is migration or conversion rather than asset recovery. The stated openness to exploring other collaborations leaves room for follow-up announcements from either party, though none had been outlined beyond the August 24 statement.

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.
