Sui Network Support Ending
Phantom Wallet Will Discontinue Support for Sui Network Starting September 24, 2026
Key Points
The decision to discontinue Sui support is described as a mutual agreement between Phantom and the Sui team, not a unilateral move.
Phantom has set an exact one-month migration window—assets must be moved by September 24, 2026 following an August 24 announcement.
Sui’s on-chain metrics have deteriorated since Phantom’s integration: current TVL around $470.38 million and SUI price near $0.83, after a peak above $2 billion TVL and an all-time high of $5.36 in January 2025.
After September 24, 2026, Phantom will stop displaying Sui balances and remove Sui from its network list; Sui dapps and transactions via Phantom will cease, and users must reconnect to a replacement wallet to use Sui apps.
Phantom is waiving its own cross-chain conversion fee for moving native SUI to wrapped SUI on Solana until the cutoff, but network and exchange fees still apply; the fee waiver ends at the deadline.
Phantom, one of the crypto world's most popular wallets, is dropping support for the Sui blockchain on September 24, 2026. Crypto News reports the move comes less than 20 months after Phantom added Sui to its platform. Users have until the deadline to move their SUI tokens or convert them to other assets, as Phantom will stop displaying balances and processing Sui transactions after that date.
The withdrawal follows Sui's declining performance. The network's total locked value has tumbled to $470.38 million, down from over $2 billion at its peak. Cryptopolitan notes that SUI's price has slid to around $0.83, far below its January 2025 all-time high of $5.36. Crypto Briefing emphasizes this was a mutual decision between Phantom and the Sui team, not a unilateral move.
Two Ways to Move Your Crypto Before the Deadline
Users have two options to protect their SUI holdings. First, they can convert native SUI to wrapped SUI on the Solana network using Phantom. The wallet is waiving its conversion fee until September 24, though network fees still apply. Second, users can export their recovery phrase and move assets to another Sui-supporting wallet. Crypto News reports that Slush is recommended by the Sui Foundation.
What Happens to Your Funds After September 24
After the September 24 deadline, Phantom will no longer display SUI balances or allow Sui transactions. Crypto Briefing explains that users won't be able to view, send, swap, or interact with Sui assets through Phantom's interface. The network will be removed from Phantom's roster entirely. However, funds remain safe on the Sui blockchain itself and under the user's control through their recovery phrase or private key.
Users who don't migrate before the deadline will need to reconnect to a different wallet to access Sui dapps and complete transactions. CryptoNews emphasizes that Phantom does not custody user funds, so assets never leave the blockchain. The wallet simply stops being a gateway to view and manage them.
Sui's Sharp Decline Since Phantom Integration
Phantom integrated Sui support in early 2025, right as the network peaked. Crypto Briefing reports that Sui's total locked value once exceeded $2 billion. The price climbed to an all-time high of $5.36 in January 2025. Both metrics have plummeted since then, signaling weakening confidence in the network and dwindling developer activity.
The timing is striking—Phantom's support barely lasted 20 months. Cryptopolitan attributes the withdrawal to Sui's persistently weak on-chain activity. As user interest dropped, the value locked in Sui dapps fell sharply. The mutual agreement suggests both teams acknowledged that Phantom's presence was no longer essential to Sui's ecosystem.
One Month to Act Before Access Disappears
The one-month window runs from the August 24 announcement to September 24, 2026. Crypto News stresses this is a hard deadline. Users who procrastinate risk losing convenient access to their SUI holdings through Phantom. After that date, they'll need to use a different wallet entirely to manage Sui assets on the blockchain.
