In some cases, certain existing wallet users may encounter a minor technical issue that prevents the direct addition of the Linea Mainnet through the standard process. This situation can be resolved through a straightforward workaround: removing the current wallet instance and subsequently re-importing it into your wallet application. This process refreshes the wallet's network configuration and resolves compatibility issues. The following section provides detailed instructions for this alternative approach.

Critical Security Notice: Before proceeding with wallet removal, ensure you have securely saved and verified your private keys or mnemonic phrase. Failure to do so may result in permanent loss of access to your digital assets.

Importing Linea Wallet into Mobile Applications

For users who need to import their Linea wallet or refresh their wallet configuration, begin by tapping the profile icon located at the top right corner of the application interface. This action opens your account management menu, where you should select the "+ Add a Wallet" option. The system will then present you with multiple import methods, allowing you to choose between software wallet import (using mnemonic phrase or private key) or hardware wallet connection.

Proceed by entering or pasting your 12-word or 24-word mnemonic phrase, or alternatively your private key, into the designated secure input field. The application employs encryption to protect this sensitive information during the import process. After entering your credentials, input "Linea" into the network search bar and select it from the available options. Upon completion, you will have successfully imported your wallet and added the Linea mainnet to your available networks, enabling full access to Layer 2 functionality.

This import process not only adds the Linea network but also synchronizes your existing assets and transaction history associated with that wallet address, providing a complete view of your blockchain activities across different networks.

Transferring Tokens on Linea Mainnet via Mobile Application
