Phantom will end support for the Sui network on September 24, 2026, closing an integration that brought SUI and Sui-based assets into the multichain wallet for roughly 20 months.

Phantom and the Sui team jointly agreed to discontinue the integration, while leaving the door open to working together again. Users have one month to swap their Sui assets into networks Phantom will continue to support, or to move access to a Sui-compatible wallet.

The September 24 cutoff removes Sui balances and transaction functionality from Phantom's interface. It does not move, freeze or destroy the underlying assets, because Phantom remains a self-custodial wallet and users retain control of their keys.

Two Paths: Swap Inside Phantom or Move to Another Wallet

Sui holders who want to remain inside Phantom can swap their assets into supported tokens before the deadline, with Phantom waiving fees on the transition swaps. SOL, ETH and USDC are among the assets users can move into while continuing to use the wallet.

Users who prefer to keep their assets on Sui can instead export their recovery credentials and restore the same account in a compatible wallet. Slush, developed by Mysten Labs, replaced the former Sui Wallet and supports browser, mobile and web access. Suiet remains another native Sui option.

After September 24, SUI and other Sui assets held by the address will remain on the blockchain, even though Phantom will no longer display balances, send transactions or provide Sui swaps. Users should only enter a recovery phrase into verified wallet software and avoid migration links sent through direct messages or social media.

A similar access problem affected Cosmos users earlier this year, when the Leap Wallet shutdown forced users to restore their accounts elsewhere rather than move assets at the blockchain level.

Phantom Added Sui During Its Multichain Expansion

Phantom launched Sui support on January 29, 2025, initially in beta before opening the integration to all users in May. Sui became the first Move-based network supported by Phantom — Move being the smart-contract language originally developed for Meta's abandoned Diem payments project and shared with competing chains such as Aptos — joining Solana, Ethereum, Bitcoin and Base inside the wallet. Phantom itself began as a Solana-only wallet before that multichain expansion, so the delisting trims a roster built through cross-chain growth while the wallet's original chain remains supported.

The integration covered SUI transfers, Sui ecosystem tokens, decentralized applications and cross-chain swaps. Sui was still included in Phantom's experimental AI wallet tools in February 2026, when the wallet's MCP server supported wallet addresses and signing across Solana, Ethereum, Bitcoin and Sui.

Sui Network Activity Continues Beyond Phantom

Sui has continued adding network features independently of Phantom, including gasless stablecoin transfers for seven assets launched in May. The network is also preparing post-quantum signature support and has expanded Slush as its primary wallet interface.

SUI traded around $0.83 on August 24 after gaining sharply during the previous week, with no comparable network halt accompanying the Phantom announcement.

Phantom users holding Sui assets have until September 24, 2026 to complete swaps or restore their accounts in another Sui-compatible wallet before Sui transaction support disappears from the Phantom interface. Beyond the cutoff, the open questions are whether Phantom's supported-network lineup changes again, whether migrating users settle on Slush or Suiet as their primary Sui wallets, and whether the two teams act on the stated openness to working together again.
