Non-custodial multichain wallet Phantom has confirmed that it will end support for the Sui network on September 24, 2026. The announcement was made in a coordinated release through the company’s official X account and a dedicated help center article published this week.
After the cutoff, users will no longer be able to view Sui balances, send or receive SUI, execute in-app swaps involving Sui assets, or interact with Sui-based decentralized applications through the wallet, and Sui will be removed from the network list within the app.
The wallet has emphasised that user funds are neither frozen nor lost. Because Phantom is a self-custodial wallet, the assets remain on the Sui blockchain and can be accessed at any time by importing the same recovery credentials into another Sui-compatible wallet.
Migration Path: Swap or Export
Phantom has outlined two migration routes ahead of the September 24 deadline. Users who want to stay within the Phantom ecosystem can swap their native SUI into a supported asset before the transition date.
The company has waived its own fee on cross-chain swaps from native SUI to wrapped SUI on Solana through the transition window, although network and exchange fees will still apply. Users may alternatively swap into SOL, ETH, or USDC, but standard fees apply on those routes.
Those wishing to continue transacting on Sui after the cutoff can export their Secret Recovery Phrase from Phantom, accessible via Settings, Security & Privacy, and Show Recovery Phrase. That phrase can then be imported into another Sui-native wallet.
Phantom’s help article explicitly points to Slush, the Sui Foundation’s recommended wallet, as a compatible option. Additional recovery phrases or private keys imported into Phantom that hold Sui assets will need to be exported and imported separately.
Any dApp connections previously established through Phantom on Sui will stop working after the transition date, and users will need to reconnect through whichever wallet they migrate their credentials to. The company has also confirmed that there is no deadline for users to eventually restore their wallets elsewhere, since assets remain on-chain under user control at all times.
Scam Warning Around the Migration Window
In a notable inclusion, Phantom has reiterated that it will not proactively contact users, request Secret Recovery Phrases or private keys, or offer to move funds on a user’s behalf. Any outreach of that nature, whether on X, Telegram, Discord, or via email, should be treated as a phishing attempt by the recipient.
Migration announcements have historically been fertile ground for scam operators impersonating official support, and Phantom’s advisory appears designed to pre-empt the pattern seen during previous chain-support windups across the industry. The company has directed users to rely solely on guidance published inside the app or in its official help article.
A Repeat of the Monad Playbook
The Sui wind-down mirrors, almost line for line, Phantom’s July decision to end support for the Monad network on August 26, 2026, which The Crypto Times reported earlier. In both cases, the wallet gave roughly a month of notice, waived its own swap fees for cross-chain migration to a wrapped Solana-based equivalent, and offered a two-track exit of either swapping out or migrating credentials.
Phantom first announced Sui integration in December 2024 and formally launched the feature on January 29, 2025, making Sui the first Move-based chain to be integrated into the wallet. At the time, Christian Thompson, then Managing Director of the Sui Foundation, described the integration as validation of the ecosystem’s growth, while Phantom CEO Brandon Millman framed the addition around Sui’s scalability and user experience. Neither party has publicly cited a specific reason for the current wind-down.
Phantom, which raised $150 million at a $3 billion valuation in a Sequoia and Paradigm-led Series C round in early 2025, reports over 15 million monthly active users and roughly $20 billion in annualized token swap volume. Two Layer-1 exits inside two months suggest an active consolidation of the wallet’s supported network roster, though the company has not published a formal criteria list for network review.
SUI Market Snapshot
At press time, SUI was trading at approximately $0.81, down around 3.1% in the last 24 hours but up 20.8% over the past seven days, according to CoinGecko data. The token holds a market capitalization of roughly $3.31 billion, placing it 29th by market cap, on a circulating supply of 4.07 billion out of a 10 billion maximum supply. Fully diluted valuation stands near $8.11 billion, with 24-hour trading volume at approximately $621.9 million.
The announcement’s near-term price impact appears contained relative to the token’s weekly performance. However, the removal from one of the industry’s most-used consumer wallets marks a notable narrowing of Sui’s retail distribution surface heading into the September deadline.
