Phantom drops Sui support: Sept 24 migration deadline
Phantom, the multichain wallet, announced that it will stop supporting the Sui network on September 24, giving users one month to migrate their assets before the integration ends. The change follows a joint agreement between Phantom and the Sui team, framing it as a mutual transition rather than a unilateral delisting.
Phantom drops Sui support but says users are not at risk of losing funds. The wallet will not take custody or interfere with private keys. Instead, users can either (1) transfer SUI assets to another Sui-compatible wallet (Suiet and the official Sui Wallet are listed) or (2) swap SUI into assets that Phantom continues to support. Phantom is waiving swap fees for these migrations before September 24. It is also rolling out in-app notifications and a step-by-step migration guide.
Phantom first announced Sui support in December 2024 and launched the integration on January 29, 2025. The Sui addition came during a broader multichain expansion beyond Phantom’s Solana roots, including support for Ethereum and Bitcoin. The wallet also dropped support for the Monad network on August 26, shortly after the Sui announcement, suggesting a deliberate thinning of its network roster.
For traders, Phantom drops Sui support may create short-term friction for SUI holders using Phantom, including migration-driven flows and temporary liquidity shifts, but it is not an on-chain shutdown of Sui itself.
Neutral
Phantom drops Sui support is a product/integration change for a specific wallet, not a protocol-level disruption. Because Phantom explicitly states that users keep control of private keys and assets, the event is unlikely to trigger a broad loss-of-funds panic. In similar past cases—when major wallets temporarily delist or sunset a chain’s integration—market impact has usually been limited to short-term flow effects and short-lived sentiment pressure rather than sustained price trends.
Short term, SUI holders who rely on Phantom may migrate during the final month, creating localized liquidity shifts and potential volatility around fee-eligible swaps (until September 24). Some users may also rotate to other wallets, slightly reducing Phantom-based demand for SUI.
Long term, the bigger question is whether the migration burden increases friction enough to reduce active wallet usage on Sui. However, Sui itself remains live, and alternatives are available, which typically limits the macro effect on market stability.
Net: likely neutral, with watchpoints on SUI liquidity/DEX volumes and wallet-to-wallet flow data leading up to September 24.
