+# Solana
+
+[Solana](https://solana.com/) is a high-performance, non-EVM network that provides fast transaction speeds and low fees.
+You can interact with users' Solana accounts in MetaMask using the [Wallet Standard](#wallet-standard) or [third-party libraries](#third-party-libraries) for Solana dapps.
+
+:::note Supported Solana networks
+MetaMask supports Solana Mainnet.
+Solana Devnet is only supported on [MetaMask Flask](/snaps/get-started/install-flask).
+After adding Solana to MetaMask Flask, [show test networks](https://support.metamask.io/configure/networks/how-to-view-testnets-in-metamask/) to view Solana Devnet.
+:::
+
+:::info Extension only
+Connecting your dapp to Solana in MetaMask is currently only available on the extension.
+Mobile support is coming soon.
+:::
+
+## Wallet Standard
+
+MetaMask implements the [Wallet Standard](https://github.com/wallet-standard/wallet-standard), so MetaMask is supported out-of-the-box for Solana dapps that use the Wallet Standard or that integrate Solana's [Wallet Adapter](https://github.com/anza-xyz/wallet-adapter/blob/master/APP.md).
+
+Learn more in Solana's [Interact With Wallets](https://solana.com/developers/courses/intro-to-solana/interact-with-wallets) documentation.
+
+:::note
+With the Wallet Standard, MetaMask does not appear as a connection option for users that don't already have MetaMask installed.
+Ask the MetaMask team on [Discord](https://discord.gg/consensys) if you need support for a custom integration.
+:::
+
+## Third-party libraries
+
+Several third-party libraries for Solana dapps detect and handle MetaMask out-of-the-box, including:
