# Name your wallet with an ENS

When you create a Loopring Smart Wallet, a randomly generated address of 42 letters and numbers is created for the wallet. This address is used when you send and receive Ethereum-based assets, such as sending LRC from another service to your wallet, or when receiving an NFT.

{% hint style="info" %}
A Loopring ENS follows the format of **\[your-unique-name].loopring.eth**. Purchasing an ENS for your Loopring Smart Wallet makes it easier for you to send and receive Ethereum-based assets because you don’t need to use your original 45-character address, which can lead to errors if not correctly copied and pasted during transactions.

### 1. Before you begin <a href="#before_you_begin" id="before_you_begin"></a>

Review the following considerations and limitations for using an ENS:

* Your Loopring Smart Wallet can have only one ENS. After you purchase an ENS, you can’t replace it or purchase a new one.&#x20;
* The name for your ENS must be 4-12 characters long and can’t already be in use.&#x20;
* The more characters in your ENS, the higher the ENS purchase fee will be.
* Your ENS can’t contain special characters or uppercase letters.
* You must purchase your ENS using LRC on Layer-2 or Loopring Points.

### 2. Understanding the ENS purchase fee <a href="#understanding_the_ens_purchase_fee" id="understanding_the_ens_purchase_fee"></a>

The total cost to purchase an ENS involves two fees: the ENS registration fee and the [Ethereum gas fee](https://ethereum.org/en/developers/docs/gas/).\
The ENS registration fee is a flat fee that is charged by the ENS Foundation to register an ENS. \
The Ethereum gas fee is a variable fee to add your ENS to the registry. Consider creating your ENS when gas fees are lower.

{% hint style="info" %}
**Wallet tip:** Here you can track the gas fee rates to get a much better price quotation when creating your wallet. The lower the gas fee rate is, the lower the activation cost is needed. \

### 3. Create an ENS <a href="#create_an_ens" id="create_an_ens"></a>

1. From your Loopring Smart Wallet, tap **Gear icon** > **Manage Current Wallet**.&#x20;
2. Tap your **profile details** (top portion of the screen) then tap **ENS**.
3. Enter a name for your ENS, and then tap Next.
4. Optional: Tap the total cost to change your method of payment.
5. Review your purchase, and then tap Confirm.

{% hint style="success" %}
You have successfully named your wallet! It should now be easier to remember your wallet address.
