# Gate: JEFF Bridge

The JEFF Bridge connects the **Base Chain** with other blockchains, allowing users to seamlessly transfer assets between chains. However, the bridge only supports transfers between wallets owned by the same user.

Currently, the bridge supports transfers between **Ethereum** and **Base Chain**.\
Supported assets:

* **$JEFF Tokens**
* **LAND NFTs**
* **AKDONG NFTs**

***

#### ***※ Important Notes***

* Using the bridge requires gas fees:
  * **$JEFF Tokens** (for Base Chain)
  * **$ETH** (for Ethereum Chain)
* You must connect your MetaMask wallet to your JEFF World account(Go to Mypage) to use the bridge.
* The transfer process consists of **3 steps**:\
  **Approve → Send → Claim**

## How to Access the Bridge

* Log in to the JEFF World homepage.
* Navigate to the **"Bridge"** section in the menu tab.
