- Sui's current TVL stands at approximately $469 million.

Phantom Wallet has announced it will end support for the Sui network on September 24, 2026, a decision that comes as Sui's total value locked (TVL) has plummeted by 82% from its peak. The integration, which began in late 2024, is being discontinued due to the sharp contraction in capital on the Layer-1 network.
Sui's TVL reached a high of approximately $2.58 billion in October 2025, but has since fallen to around $469 million. This decline has made continued support less viable from an infrastructure perspective, despite earlier institutional backing such as Coinbase's launch of Sui staking services.
Following the September 24 deadline, Phantom will no longer display Sui balances or facilitate Sui transactions. Users' assets will remain on the Sui blockchain and can be accessed using any compatible wallet with the same recovery phrase. Phantom suggests Slush (slush.app) as the Sui Foundation's preferred alternative.
For users who wish to remain with Phantom, the wallet is waiving its own fees for cross-chain swaps from native SUI to wrapped SUI on Solana until the deadline, though network and exchange fees will still apply. The delisting follows a pattern of Phantom ending support for less active networks to focus on higher-traffic chains like Solana, Ethereum, Base, and Bitcoin.
The exit from Phantom adds friction for SUI holders, particularly as the network faces reduced developer activity and capital outflows. While Sui possesses technological strengths like its Move-based architecture and parallel execution model, its recovery hinges on attracting new applications, stablecoin growth, or renewed capital inflows to reverse the TVL trend.
