Phantom to End Sui Support on September 24 as SUI TVL Falls 82%

Phantom will end support for the Sui network on September 24, 2026, less than 20 months after adding native Sui support. The decision means Phantom users will soon lose the ability to view, send, swap or interact with Sui assets through the wallet.

The announcement comes as Sui's total value locked (TVL) has fallen sharply, adding to concerns about declining capital and activity across the network.

Phantom Ends Sui Wallet Support

Phantom said the decision was reached jointly with Sui and left open the possibility of future collaboration between the two projects. Importantly, Sui assets will not be lost when Phantom support ends.

After September 24, Sui balances will no longer appear in Phantom, while Sui transactions, swaps and connected applications will stop working. The assets themselves remain on the Sui blockchain and can still be accessed through another compatible wallet using the same recovery credentials.

Users who want to continue holding SUI have two options. They can move their wallet to another Sui-compatible application, with Phantom recommending Slush, or they can swap native SUI into a supported asset before the deadline.

Phantom has also waived its own fee for swapping native SUI into wrapped SUI on Solana through September 24, although network and exchange fees still apply.

Sui TVL Falls 82% From 2025 Peak

The Phantom Sui support shutdown comes against a backdrop of significantly lower capital locked in the Sui ecosystem.

Sui's TVL has fallen from approximately $2.58 billion in October 2025 to around $469 million, representing an 82% decline from its peak.

The decline does not necessarily mean that all Sui network activity has disappeared, but the reduction in TVL represents a substantial contraction in capital deployed across its decentralized finance ecosystem.

For SUI holders, Phantom's decision therefore creates another factor to monitor as the network attempts to rebuild liquidity and ecosystem activity.

What Sui Holders Should Do

Phantom users holding SUI should complete any desired swaps or wallet migration before September 24. Missing the deadline will not destroy the assets, but users will need to access their funds through another compatible Sui wallet.

Phantom has also warned users that it will never contact them asking for their recovery phrase or private keys. Users should therefore avoid unsolicited messages offering assistance with the migration.

The end of Phantom's Sui support marks a significant reversal less than two years after the wallet integrated the network. Whether the decision has a lasting impact on Sui adoption will depend on how effectively the ecosystem retains users, liquidity and wallet access following the transition.
