Woofun AI reports that Phantom Wallet will discontinue Sui network integration on September 24, 2026, a strategic retreat driven by an 82% collapse in total value locked. This decision aligns with a broader resource reallocation toward higher-traffic ecosystems, including Solana, Ethereum, Base, and Bitcoin, following a similar withdrawal from Monad.

Woofun AI data shows that the financial deterioration was precipitous, with Sui's total value locked plummeting from $2.58 billion to $469 million. Although the network briefly touched all-time highs on August 24, 2026, the surge proved short-lived, rendering continued active integration economically unfeasible for the wallet provider.

Operationally, users will no longer see Sui balances or process transactions within the interface, though assets remain secure on the Sui blockchain and recoverable via any compatible wallet. Slush (slush.app) has waived its own fees for affected users, although standard network and exchange fees still apply to remaining activities.

Structurally, the exit reflects declining developer activity and persistent capital outflows that have overshadowed the chain's technological strengths. While new applications and stablecoins may eventually drive capital inflows, the current trajectory suggests a prolonged period of consolidation for the ecosystem.
