Phantom will end support for the Monad network on Aug. 26, the wallet company said on X on Friday, cutting off the high-throughput EVM chain roughly nine months after its November 2025 mainnet launch.

"We'll soon begin notifying Monad users in-app with links to support articles that share options to move or swap their Monad-native assets," Phantom said. Because Phantom is self-custodial, Monad assets remain accessible after the cutoff: users can import their recovery phrase into another wallet that supports the chain.

The two companies gave different deadlines. Monad's own post on X, published about three hours before Phantom's, told users Phantom support ends Aug. 12 and urged them to migrate to another EVM wallet before that date, pointing to a list of supported wallets in its documentation. Neither team had publicly reconciled the dates by press time.

Monad co-founder and CEO Keone Hon said Phantom told the team it is removing Monad, along with another network, "in an effort to focus more on their core business."

"We want Monad to be everywhere, so this is a step backward at a moment when we are trying to take many steps forward to connect Monad (and crypto more generally) to all parts of the financial economy," Hon wrote on X on Saturday. He noted that Phantom, unlike most EVM wallets, does not let users add networks themselves: "Time will tell which strategy is right for the EVM."
