MetaMask also announced that support for Solana on its mobile platform is expected to launch in the coming weeks.

Solana is just the start. We’ll be adding more non-EVM networks over the coming months, to make wallet juggling a thing of the past. One wallet, one interface, every network,” MetaMask.

While the Solana network is not yet available on the MetaMask mobile app, mobile support is expected "in a few weeks," according to the company.
