# Manage wallets

## Import an existing wallet

Optionally import a mnemonic string of an existing EOA wallet and store it on the user's device.

```dart
final someExistingMnemonic = "some value from other product or IO...";
final wallet = await WalletManager.getInstance().importExistingWallet(someExistingMnemonic);
```

## Reading balances

## Recovery and persistence

By default, EOA wallets are generated on-device and backed up to the user's cloud.  Read about [key persistence](https://docs.rallyprotocol.com/flutter/how-it-works#persistence) here.
