Zerion Wallet is non-custodial and your data is always stored locally, Zerion does not have access to it.
Just follow these steps to import your external wallets to Zerion:
Tap on ‘Manage wallets’ in the Settings tab
Select ‘Import wallet to Zerion’
Paste your seed phrase / private key and tap on ‘Import’. You can usually find them in the wallet’s settings.
You could also scan the WalletConnect QR code to make the process faster. Please keep in mind that since all the wallet details are stored locally you would need to import your seed phrase or your private key for each wallet imported from the web app.
You can also use the QR code scanner to connect your wallet to dApps.
