Phantom is dropping Sui on Sept. 24 — your coins stay, the interface leaves

Phantom will remove Sui from its wallet interface on Sept. 24, one month after announcing on Aug. 24 that it and Sui had jointly decided to end the integration. After that date Phantom will no longer show Sui balances, support Sui sends or swaps, or connect to Sui applications. The assets themselves stay on the Sui blockchain, tied to the credentials that authorize the account, and Phantom's transition guide says users can restore access through a compatible wallet even after the cutoff. Neither company has given a reason for the split.

That gap between ownership and access is the lesson here. A self-custodial wallet provider cannot take your coins, but it can withdraw the screen, the transaction buttons and the app connections you actually use the chain through. Sui support went live in Phantom on Jan. 29, 2025, and at launch the Sui Foundation said Phantom users could send, receive and manage Sui assets, swap SUI, and connect to applications including Suilend, Navi, Aftermath and Bluefin. The same interface that carried the network to users can now take it off the list.

Phantom's guide splits users by what they want to keep. Anyone who wants to stay inside Phantom can swap out of native SUI. Recovery-phrase users who want to keep native Sui exposure can import the same account into Slush. Ledger users have a separate connection path that keeps keys inside the hardware wallet. The advertised fee waiver is narrower than the short announcement suggests: it covers only Phantom's own fee on cross-chain swaps from native SUI to wrapped SUI on Solana, while network and exchange fees still apply, and swaps into assets such as SOL, ETH or USDC carry standard fees.

How much work the move takes depends on how your account is secured. Phantom tells recovery-phrase users moving to Slush to view the phrase inside Phantom, record it offline, and import it into the destination wallet, and any additional recovery phrases or private keys previously imported into Phantom have to be handled one by one. Hardware-wallet users are a different case: Phantom says a supported hardware wallet keeps private keys offline and that the phrase and private keys are not exposed to the app, and Slush separately documents a direct Ledger connection for Sui accounts, though the general sunset guide does not spell that path out.

A dated migration is also a scam window, and this is the part beginners should read twice. When people are told to expect new instructions, new downloads and credential prompts, impersonation gets easy cover. Phantom says it will not contact users first, will not request a recovery phrase or private key, and will not offer to move assets for anyone. Slush's security guidance likewise says its staff will not initiate direct messages or ask for a recovery phrase. One public reaction, from Ivan on Tech, criticized key export as bad for security; it is a single attributed opinion rather than a consensus, but it names the real tension, which is that portability only helps if you can move safely.

Missing the date is not the same as losing money. Sui keeps running, ownership does not change hands, and access can be restored later through compatible software. How many people this affects is unknown: the 15 million monthly active users cited at the Sui integration launch, up from seven million in a December 2024 announcement, describe Phantom overall, not Sui users inside it, and no affected-user count has been published. The practical caution is to not let a deadline rush you into typing a recovery phrase into software you did not get from an official site.
