+## Wallet
+
+### Create a new wallet
+
+```bash
+wallet create
+```
+
+> Add the `--no-password` flag to skip the optional encryption step.
+
+> **Wallet Security**
+>
+> Encrypted wallets provide an additional layer of security, requiring a password to read the private key and perform
+> transactions. However, ensure you remember your password; losing it may result in the inability to access your encrypted
+> wallet.
+
+Example:
+
+   ```bash
+   $ wallet create
+   Enter password (leave empty for none):
+   Repeat password:
+   Wallet address: 0xaf676aC7C821977506AC9DcE28bFe83fb06938d8
+   Stored wallet in: "/Users/macuser/Library/Application Support/safe/autonomi/wallets/0xaf676aC7C821977506AC9DcE28bFe83fb06938d8.encrypted"
+   ```
+
+### Import a wallet
+
+```bash
+wallet create --private-key <PRIVATE_KEY>
+```
+
+### Check wallet balance
+
