## Main Chain ELA > Elastos Smart Chain ELA (side chain)

### Essentials wallet

Assume you decided to buy your ELA on one of the [centralized exchanges](https://creda-app.gitbook.io/creda-protocol/elastos-guides/where-can-i-buy-ela).

### Step 1&#x20;

Make sure you are connected to the Elastos network and tap in the middle of the purple field (as shown on the image below)

**It will open next screen**

Here you can see your wallet balance:

* ELA on Main Chain
* ELA on Identity Chain (EID)
* ELA on Smart Chain (ESC)

**Select ELA on Main Chain**

**Select RECEIVE in the bottom right corner**

Copy your ELA Main Chain wallet address (tap to copy)

### Step 2

Visit the exchange website where you acquired your ELA and on the withdrawal process window, paste your ELA Mainchain wallet address.

{% hint style="info" %}
Always use ONLY Main Chain wallet address for any withdrawals from centralized exchanges!\
\&#xNAN;*(note: Coinbase has ERC20 version of ELA, so DO NOT withdraw it as part of this process or you will loose all of your ELA)*
{% endhint %}

Wait for the withdrawal process to complete. For this guide purpose, we have withdrawn 1 ELA.

### Step 3

Now that you received your ELA, tap again in the middle of the purple field

**Select Main Chain**

And now we will **send** 1 ELA **from Main Chain to Elastos Smart Chain** (side chain)

{% hint style="info" %}
Elastos cross-chain transfer usually takes between 15 and 25 minutes. During this time you will not see your funds, please remain patient.
{% endhint %}

**Congratulations!**\
You now have your ELA on Elastos Smart Chain (ESC) and you are all set to interact with CreDA dApp on the Elastos network.
