# Bridge $BNRY between Optimism and Ethereum

This step involves using **Wormhole**, a bridge protocol, to transfer **BNRY tokens** from the **OP (Optimism) L2 network** to the **Ethereum L1 network**. **The OP L2 network** is an **Ethereum Layer 2 scaling solution**, and bridging involves moving tokens from this layer to the **Ethereum mainnet layer**.

### Step 1: Initiating the Transfer

1. Navigate to [Wormhole Bridge](https://portalbridge.com/advanced-tools/#/transfer?sourceChain=optimism\&targetChain=ethereum). 
2. Connect your wallet

3. Click **Select a token** and paste the [**BNRY token** **address**](https://optimistic.etherscan.io/token/0xb5090d514bcaca7dafb7e52763658844121f346d)

4. Enter the amount of **BNRY tokens** you wish to bridge.

5. Approve and confirm the transfer.&#x20;

> Once the transfer is confirmed, you will receive a transaction hash.

### Step 2: Wait for Confirmation

* After initiating the transfer, wait for **Wormhole** to process and confirm the transaction
* The transaction needs to receive 13 out of 13 signatures to be ready for redemption.&#x20;
* You can use the transaction hash to monitor on [**Wormhole Explorer**](https://wormholescan.io/)

### Step 3: Redeeming Tokens on Ethereum

Go to [Wormhole Redeem](https://portalbridge.com/advanced-tools/#/redeem).

1. Connect your wallet and choose **Optimism** as the source chain.
2. Paste the transaction hash.
3. Click on the "**Recover"** button and confirm the transaction.&#x20;

4. Once confirmed, the bridging process is complete, and your **BNRY tokens** will be available on **Ethereum**.
