Users holding assets on Sui through Phantom must move funds before the cutoff date, reports say.
Phantom is removing support for the Sui network, according to reporting from CryptoBriefing. The wallet provider has given users until September 24 to move any Sui-based assets before access through Phantom ends. CryptoBriefing’s report frames the change primarily as a logistical shift, centered on the migration deadline itself.
Cryptopolitan covered the same development but placed it in a different context. That outlet linked the decision to Sui’s difficulty regaining traction as a layer-1 blockchain. Neither report specified the exact reasons Phantom gave for dropping the integration, and the two accounts differ in emphasis rather than in the core fact of the discontinuation.
Phantom built its reputation as a Solana-native wallet before expanding to support multiple chains, including Ethereum, Polygon, and Sui. Adding new networks has been a common strategy among wallet providers competing for users who hold assets across several ecosystems. Removing a chain is less common and typically signals either low usage, technical maintenance costs, or a strategic narrowing of focus.
Sui launched as a high-throughput layer-1 blockchain built by Mysten Labs, a team with roots in Meta’s former Diem project. It positioned itself as a competitor to Solana and other performance-focused chains, emphasizing parallel transaction processing. Despite early attention, Sui has faced questions about sustained developer activity and user growth relative to rival networks.
For users affected by the change, the practical concern is straightforward. Anyone holding Sui-based tokens, NFTs, or other assets within Phantom needs to transfer them to another compatible wallet before the September 24 deadline. Missing that window could complicate access to those holdings, though neither report detailed what specifically happens to funds left unmigrated.
Wallet providers periodically reassess which chains justify continued engineering and support resources. Maintaining multi-chain compatibility requires ongoing updates as networks upgrade their protocols. A decision to drop a chain often reflects an internal calculation about user demand versus maintenance cost, rather than a single dramatic event.
The timing of Phantom’s announcement, paired with commentary about Sui’s momentum, may draw added scrutiny to the network’s competitive standing. Observers will likely watch whether other infrastructure providers make similar decisions in the coming months.
Sources disagree on this story
This article was published before the reports below were compared. The reporting above stands; what follows is where the published accounts do not agree.
Reports agree Phantom is ending Sui support September 24, but differ on why the integration is ending and which wallet Phantom recommends for retaining native Sui assets.
What all sources agree on
- Phantom will end support for the Sui network on September 24.
- Users will not lose their funds; assets remain on the Sui blockchain accessible via recovery phrase.
- Phantom is waiving fees for swaps out of Sui before the deadline (network/exchange fees still apply).
- Phantom also dropped support for the Monad network.
Where the reports disagree
1Stated reason for ending Sui support
The decision came through a joint agreement between Phantom and the Sui team, which makes it a mutual parting rather than a unilateral cut.
Phantom has not publicly explained why it is withdrawing the integration.
Its support notice describes the decision as a product transition and does not provide a technical or commercial reason.
The exit comes after a sharp decline in Sui activity, with DeFi TVL falling from around $2 billion to below $1 billion and SUI trading far below its 2025 peak.
What would settle it: Phantom's official statement or support notice explaining the reason for ending Sui support.
2Which wallet Phantom recommends for retaining native Sui assets
Users can transfer their Sui assets to another Sui-compatible wallet, with Suiet and the official Sui Wallet listed as alternatives.
The Phantom wallet recommends Slush as the preferred wallet of the Sui Foundation and indicates that the same address and balances should be reflected automatically.
Phantom recommends Slush, the wallet associated with the Sui ecosystem.
What would settle it: Phantom's official support page or migration guide listing recommended wallets.
What to make of it
Treat the September 24 deadline, fee waivers, and no-loss-of-funds points as established across all sources; do not rely on any single account of why Phantom is exiting Sui or which replacement wallet it recommends until Phantom's own statement or support page is checked directly.
Market Impact
A wallet dropping support for a blockchain can reduce that network's accessibility for retail users, even if the underlying protocol remains functional. Reduced wallet compatibility may modestly affect user activity metrics for Sui, particularly among users who relied on Phantom as their primary access point.
The broader significance lies in what the move signals about competitive positioning among layer-1 blockchains. If additional wallets or infrastructure providers follow with similar decisions, it could reinforce perceptions about Sui's relative standing versus other high-throughput chains. No pricing or trading volume data was provided in the reports, so any direct market effect remains unconfirmed.
Users with Sui assets in Phantom should plan to migrate before September 24 to avoid disruption, while the broader implications for Sui's ecosystem position remain to be seen.
