Phantom, a popular self-custody crypto wallet, will end support for the Sui blockchain on Sept. 24, removing balances, sends, swaps and dapp connections for Sui from inside its app. If you keep Sui in Phantom, this change directly affects how you view and move that money.
What Phantom Is Changing for Sui Users on Sept. 24
Phantom announced that Sui support inside the wallet will be switched off on Sept. 24, according to the company’s post on X. After that date, Sui will no longer appear as a supported network in the app. For related coverage, see Canada and Australia Exit Tax: Unrealized Bitcoin Gains Explained.
Four functions are being removed together. These are balances, sends, swaps and dapp connections, all specific to Sui. For related coverage, see Artificial Intelligence Summit –Philippines 2026.
In plain terms, a dapp connection lets your wallet link to a decentralized application, meaning an app that runs on a blockchain instead of a company’s servers. All four of these Sui features go away at once. For related coverage, see Artificial Intelligence Summit –Malaysia 2026.
How the Removal Could Affect Existing Phantom Sui Users
Losing balance visibility means Phantom will no longer show your Sui holdings inside the app. The tokens are a network feature of the wallet interface, not something you can see there anymore.
Losing sends and swaps means you cannot move Sui out, or trade it, from within Phantom. A send is transferring tokens to another address; a swap is exchanging one token for another.
Losing dapp connections means Sui-based apps can no longer link to Phantom. Anyone using Sui apps through the wallet will need another way to connect.
Why Phantom’s Sui Exit Matters
This is more than a minor feature tweak. Phantom is pulling four separate Sui functions at the interface level, not adjusting a single setting.
The significance comes from a wallet withdrawing interface support for an entire chain. That kind of rollback pushes affected users toward migrating their Sui workflow to a different wallet before the deadline.
Practical takeaway: if you hold Sui in Phantom, note the Sept. 24 date and plan where your Sui activity will live afterward. Security-conscious holders may also want to review broader wallet safety trends, such as the U.S. Treasury’s push to add digital assets to quantum-readiness planning, when choosing their next setup. Newcomers weighing a first purchase can watch how wallets handle multiple chains, a factor even in popular roundups of top cryptocurrencies.
Phantom has not, in the available information, given a reason for ending Sui support. What is confirmed is the date and the exact features being removed.
