+# User Wallets
+
+SettleMint's **User Wallets** feature offers a production-ready solution for managing infinite wallets with efficiency and scalability. This tool empowers users with seamless wallet generation, ensuring **cost-effective management** and eliminating additional expenses. By generating **unique addresses for each user**, privacy is significantly enhanced, while improved performance ensures faster, parallel transaction processing through separate nonces. User wallet also simplifies wallet recovery since all wallets are derived from a single master key. User wallets use the same signing proxy to sign transactions with the corresponding user private key.
+
+## Set up User Wallets
+
+To set up your user wallets, navigate to your application, click **Private keys** in the left navigation, and then click **Create a private key**. This opens a form.
+
+Select **HD ECDSA P256** as the private key type then, enter a **name** for your deployment. You can also select the nodes or load balancers on which you want to enable the user wallets. You can change this later if you want to use your user wallets on a different node. Click **Confirm** to deploy the wallet.

+
+You can now see the address associated with that user. Remember that for networks that require gas to perform a transaction, the user wallet should contain enough funds to cover the gas price. You can fund it using the address displayed in the list.
