Phantom Removes Sui From Wallet, Users Lose In-App Access

Phantom will remove Sui support from its wallet interface on Sept. 24. After that date the app will stop showing Sui balances, prevent Sui sends and swaps, and end connections to Sui decentralized applications. The change affects only Phantom’s interface; assets remain on the Sui blockchain and remain controlled by the cryptographic credentials for each account.

Phantom and the Sui team announced on Aug. 24 that they had jointly decided to end the integration. The companies did not provide a reason for the split and did not disclose how many users will be affected.

Phantom added Sui support on Jan. 29, 2025. At launch the wallet allowed users to send and receive SUI, perform in-wallet swaps, and connect to Sui applications. After Sept. 24 Phantom will remove Sui from its network list, stop showing balances for Sui addresses, and disable any Sui transactions or dapp connections initiated through the wallet.

Phantom has cited 15 million monthly active users for the wallet since the Sui launch, up from seven million when the integration was first announced in December 2024. Those figures describe Phantom’s total user base and do not indicate how many customers held or transacted Sui through the app.

Phantom outlined three main options for users who want to retain value tied to Sui. The wallet is temporarily waiving its own fee for cross-chain swaps that convert native SUI into wrapped SUI on Solana; network and exchange fees still apply. Users can also swap SUI into other assets Phantom will continue to support, such as SOL, ETH or USDC, avoiding recovery-phrase export but incurring normal fees.

Users who want to keep native Sui balances and addresses can export a recovery phrase from Phantom and import it into a compatible wallet such as Slush. That process preserves the same Sui address and onchain holdings but requires users to manage and import the recovery phrase. Any additional recovery phrases or private keys previously imported into Phantom must be exported and imported separately. Hardware-wallet users can preserve private keys offline; Slush documents a direct Ledger connection for Sui accounts that restores interface visibility while leaving keys on the device.

Phantom’s guidance warns that exporting a recovery phrase creates an opportunity for credential theft if a user is targeted by phishing or installs malicious software during the migration. Phantom notes it will not initiate contact asking for recovery phrases or private keys. Slush’s guidance likewise states its staff will not request those secrets. Security concerns about key export were raised publicly after the announcement.

Sept. 24 will end Sui support inside Phantom’s app. Users who miss the date retain ownership of their Sui assets onchain and can restore access later through a compatible wallet, though they may face additional fees, technical steps or security choices when doing so.
