Sui Users Have Until September 24 to Leave Phantom

Phantom will end native support for the Sui network on September 24, 2026, giving holders roughly 31 days from the August 24 announcement to move or convert their Sui assets before the wallet stops displaying balances and processing transactions. The change trims Phantom’s supported network list down to three chains.

The Announcement: What’s Ending and When

Phantom confirmed the cutoff in an August 24 announcement, describing it as a mutual decision reached with the Sui team rather than a unilateral drop. After September 24, Phantom will no longer show Sui balances, and it will stop signing or broadcasting Sui network transactions entirely.

That does not mean funds disappear. Sui assets stay on-chain and under user custody, and they remain accessible to anyone holding the corresponding secret recovery phrase, per Phantom’s help documentation. The wallet is simply removing its own interface layer for that network, not touching the underlying blockchain state.

What Sui Holders Need to Do Before the Deadline

Phantom is laying out two paths for affected users. The first is an in-wallet swap: Phantom is waiving its own fee on conversions from native SUI to its wrapped equivalent on Solana through the September 24 deadline, though swaps into SOL, ETH, or USDC still carry standard network and exchange fees.

The second path is migration to a Sui-native wallet. Phantom’s documentation points users toward Slush, a wallet associated with the Sui Foundation, though any Sui-compatible wallet that accepts a standard recovery phrase will work. The process mirrors any self-custody migration: export the secret recovery phrase from Phantom, import it into the new wallet, and existing Sui addresses and balances appear automatically.

Phantom has also flagged a fraud risk tied to the transition, noting it will not initiate contact with users about the change and will never ask for a recovery phrase. Any unsolicited message offering to help move Sui assets should be treated as a scam attempt.

Missing the Deadline Doesn’t Mean Losing Funds

Users who let September 24 pass without acting will not be locked out of their holdings permanently. The recovery-phrase path stays open indefinitely as a matter of self-custody design – anyone can import that phrase into another Sui-compatible wallet after the cutoff and regain full access.

What they lose is the ability to view or move Sui assets through Phantom specifically. That’s a meaningful distinction for anyone tracking positions daily across multiple wallets: the asset isn’t at risk, but the interface convenience is gone the moment the clock runs out.

Phantom’s Network Footprint After the Cut

Once Sui is removed, Phantom supports three networks: Solana, Ethereum, and Bitcoin. The wallet launched as a Solana-native product before expanding into Ethereum and then Bitcoin, and Sui’s addition in January 2025 marked the first Move-language blockchain the wallet natively supported – a milestone Phantom highlighted at the time as part of its multichain push.

That integration ran roughly 20 months before both sides agreed to end it. Neither Phantom nor the Sui Foundation offered a detailed public explanation beyond the mutual-decision framing, though the announcement left room for future collaboration. The move follows a similar pattern to Phantom’s earlier decision to end Monad network support, suggesting a broader consolidation strategy rather than a one-off call specific to Sui.

For context on how platforms handle user access and controls when integrations shift, Phantom’s approach here echoes broader industry questions about wallet permissions and user controls that come up whenever a major access point changes its supported scope. It’s also a reminder that platform exits can leave lingering effects on user data and access long after the headline decision is made.

Why This Matters for Phantom’s Roadmap

Phantom CEO Brandon Millman discussed the company’s direction in August 2025, framing the product as building toward a consumer finance super app centered on Solana, alongside IPO considerations and M&A plans. Trimming the network list back to three chains – Solana, Ethereum, and Bitcoin – fits that stated strategy: fewer supported surfaces, but a tighter focus on the networks where Phantom’s active user base actually operates.

That’s a rational call from a product-simplification standpoint, but it’s also a reminder that wallet support is a business decision, not a permanent feature. Any asset a wallet chooses to integrate today can be cut tomorrow if the traffic doesn’t justify the maintenance cost – a dynamic worth keeping in mind for anyone holding assets on newer or lower-traffic chains inside any multichain wallet, including how supported-asset lists evolve at platforms offering wallet and payment functionality more broadly.

What Comes Next

The immediate milestone is September 24 itself – the date after which Sui balances vanish from Phantom’s interface and transactions stop processing. Between now and then, the fee-waived swap window from native SUI to wrapped SUI on Solana remains the lowest-friction option for anyone looking to convert exposure rather than migrate wallets.

Beyond that, the open question is whether Phantom and Sui’s stated openness to future collaboration amounts to anything concrete, or whether this is simply the end of the relationship. Neither party has committed to specifics beyond the mutual-decision framing, so holders should treat the current guidance – swap, migrate, or rely on the recovery-phrase fallback – as the only certainty on the table.
