According to CoinMeta, Phantom has announced that it will cease support for SUI on September 24th. Prior to this, the total locked-up value of SUI ($TVL) had declined from a peak of $2.58 billion in October 2025 to $469 million, representing a decrease of 82%. Phantom users are required to transfer their $SUI to other compatible wallets or exchange it for supported assets before the deadline. This move has raised concerns about a potential decline in network activity on the SUI platform.
