Phantom to End Sui (SUI) Support on Sept. 24

Phantom Confirms Sept. 24 Sui Cutoff

Phantom will remove Sui (SUI), a layer-1 altcoin built on the Move-based AltVM architecture, from its wallet on Sept. 24, 2026, ending access to balances, transactions, swaps and decentralized applications. The wallet provider's official X post confirms the cutoff, and the accompanying support notice stresses that funds stay safe and remain under the user's control. SUI and other tokens stay recorded on the Sui blockchain, accessible through the same recovery phrase or private key in any compatible wallet. The move reverses an expansion from January 2025, when Phantom added native Sui access less than 20 months ago; no public reason has been given for the withdrawal. Sui balances will no longer be displayed, the network will be dropped from Phantom's supported list, and existing connections to Sui applications will stop working. At launch in early 2025, the integration let users manage SUI and other network tokens, perform swaps, and connect with applications such as Suilend, Bluefin, Navi and Aftermath. Anyone switching to another wallet will need to re-establish those app connections in the new interface. Users who want to keep native SUI can import their Phantom recovery phrase into another wallet before or after the deadline, with Phantom pointing users to Slush, a wallet built for the Sui ecosystem. Alternatively, users can swap Sui assets into SOL, ETH or USDC inside Phantom before the cutoff. Through Sept. 24, Phantom is not charging its own fee for moving native SUI into wrapped SUI on Solana, but network and exchange fees remain. Wrapped SUI is a Solana-based representation of SUI, not native SUI, so holders should verify the receiving network and token contract before approving a transaction. The company cautioned that it never initiates contact, asks for recovery phrases, or offers to move funds for users, and that unsolicited migration assistance should be treated as a potential scam. The transition does not transfer, delete or convert assets automatically.

Monad Removal Follows Sui Exit

The Sui withdrawal is one of two network removals Phantom has scheduled this month. On Aug. 26, Phantom will end support for Monad, a layer-1 blockchain it added on Nov. 24, 2025, around Monad's mainnet launch; that integration will last roughly nine months. Once Monad support ends, Phantom's supported networks will total eight: Solana, Ethereum, Base, Sui, Polygon PoS, Bitcoin (Native SegWit and Taproot), HyperEVM and Robinhood Chain. The Sept. 24 Sui cutoff will then reduce that count to seven, assuming no new networks are added in the interim. The two removals signal a broader consolidation in Phantom's network lineup rather than an isolated product decision. Phantom has not reported a security breach or network failure connected with the Sui withdrawal, describing the change as a product transition and leaving open the possibility of future collaboration with the Sui team. For Sui users, the practical effect is a narrowing of wallet choices among mainstream multi-chain wallets. The migration path recommended by Phantom points users to Slush, while the Sui ecosystem's own wallet tools remain available. Phantom cautioned that phishing campaigns may impersonate support accounts, distribute fake wallet apps, or send links to sites built to steal recovery phrases. The replacement wallet should be downloaded only from its official website, and the domain should be confirmed independently before any credentials are entered. Restoring with the correct credentials should bring back the same Sui address and its assets. Each recovery phrase or separately imported private key has to be migrated one by one to restore the corresponding addresses. Phantom also reminded users that the Sept. 24 deadline applies to in-app functionality and the swap fee waiver, not to asset ownership; even if a user does nothing before the cutoff, the underlying assets can still be recovered later by importing credentials into a Sui-compatible wallet. The company has not announced any plan to resume Sui support after the transition.

Sept. 24 Migration Deadline in Focus

Phantom and the Sui Foundation described the split as a mutual agreement, emphasizing that no security breach or risk to user funds prompted the withdrawal. The decision arrives as on-chain activity metrics flag a steep slowdown: Sui’s total value locked now stands at $470.38 million, down from more than $2 billion when Phantom launched its integration, while SUI trades near $0.83 against its January 2025 all-time high of $5.36, with a market cap of roughly $3.4 billion. Despite the contraction, Sui recently introduced a protocol-level feature enabling gas-free stablecoin transfers, and Circle still lists Sui among the blockchains supported by its stablecoin infrastructure. Both parties said they remain open to exploring future collaborations, leaving the door ajar for a possible re-integration down the line.

(as of 06:57 UTC) Taken together, the composite S/R engine places SUI's immediate resistance at $0.8287 (83/100, strong), backed by Keltner Upper, BB Upper, Fibo 0.382 and the pivot point, while the nearest support sits at $0.8142 (47/100, moderate) with Ichimoku Tenkan, Kijun, S1 and HVN contributing. Spot trades at $0.8215, up 4.80% in 24 hours, with the trend firmly uptrend and RSI at 65.07 while MACD confirms bullish momentum. Derivatives positioning shows a modest perp funding rate of 0.0056% and open interest of $92,290,573, suggesting balanced leverage. Market sentiment registers Greed at 73/100 on the Fear & Greed Index. A decisive break above $0.8287 could open the path toward $0.8652 and then $0.9002 (64/100), while losing $0.8142 would expose $0.7754 (69/100) as the next strong support. The key levels to watch are $0.8287 and $0.8142 as the price consolidates in this tight range.
