Phantom to end Sui network support on September 24
Tech & Launches ·
The wallet provider will retire Sui compatibility next month, pushing users toward fee-free swaps and a migration path to other chains.
Phantom will discontinue support for the Sui network effective September 24, 2026, according to wublockchain.xyz. Users holding Sui-based assets in Phantom will need to move them to a compatible wallet before that date, or risk losing convenient access through the app's existing interface.
To ease the transition, Phantom is offering fee-free swaps and has published a wallet migration guide, according to wublockchain.xyz. The fee waiver is intended to offset the cost of converting or transferring assets out of Sui-linked holdings before support ends, while the guide walks users through the steps needed to move funds to a wallet that will continue to support the network.
The move narrows the list of chains Phantom actively maintains, a decision that affects any user who has parked Sui tokens or interacted with Sui-based applications through the wallet. Because a wallet functions as the primary interface for signing transactions and managing keys on a given network, dropping support means Phantom will no longer generate addresses, track balances, or facilitate transaction signing for Sui once the cutoff passes.
The announcement is corroborated by a second account describing the same September 24, 2026 discontinuation date and the option for users to migrate assets to compatible wallets, indicating the deadline and migration mechanism are consistently reported across available coverage.
What remains unclear is why Phantom chose to drop Sui specifically, whether the change reflects usage levels, technical maintenance costs, or a broader roadmap shift, and whether other networks could face similar reductions in support. Also unaddressed is what happens to any assets not migrated by the deadline, and whether Phantom will offer further assistance or extended access for users who miss the September 24 cutoff.
