# Gate: Mirgration(to Base)

JEFF World is now officially running on the **Base chain**.\
Assets previously used on JEFF Chain—such as **$JEFF tokens, AKDONG NFTs, and LAND NFTs**—must be migrated to Base in order to be used in the global version.

> ⚠️ **To use NFTs and tokens in Global JEFF World, you must migrate them to Base.**

#### ✅ Prerequisites

1. Go to **My Page > \[Migration]** and create your new **Base JEFF Wallet**.

   > ⚠️ **Save the Private Key securely** when it pops up. It will not be shown again.
2. Go to **My Page > \[Connect Wallet]** and register your personal wallet.

   > If you've already registered, you do not need to do this again.
3. Go to **My Page > Settings > 2nd Password**, and register your **second password**.

   > This is required for all migration actions.
