# How to Bridge Your $DBIO and $USDT to the DeBio Network Appchain

$DBIO is a native token on the NEAR Protocol but [compatible with a Substrate-based chain](https://blog.debio.network/dbio-follows-the-substrate-standard-and-the-farm-reaches-an-all-time-high-apr-in-ref-finance-e1f8ae7900e4) thanks to the Octopus Network bridge. This also applicable for $USDT.e (a token representing USDT on NEAR Protocol that was bridged from the Ethereum blockchain via the Rainbow Bridge). inside The Octopus Network bridge transfers value from a native NEAR Protocol token into their Appchains. Every Octopus Network Appchain is a Substrate-based chain because Octopus Network is built on top of Substrate for interoperability purposes.

**TL;DR** You can follow the steps outlined in the image above. For a more detailed explanation, you can read the steps below.

1. [Create a Polkadot Address](#0f65)
2. [Bridge from ETH to NEAR](#9d68)
3. [Exchanging $NEAR with $DBIO](#8a1a)
4. Exchanging $NEAR with $USDT.e
5. [Bridge From NEAR to the Appchain](#8ab2)
6. [View the Funds via Octopus Bridge](#view-the-funds-via-octopus-bridge)
7. [View the Funds via Appchain](#view-the-funds-on-the-appchain)

### Create a Polkadot Address <a href="#id-0f65" id="id-0f65"></a>

First, download the Polkadot.js extension and create a Substrate account.

### Bridge From ETH to NEAR <a href="#id-9d68" id="id-9d68"></a>

$DBIO is a native NEAR Protocol token. Using NEAR’s Rainbow Bridge, you need to bridge your Ethereum assets to the NEAR Protocol. The [Rainbow Bridge](https://ethereum.bridgetonear.org/) is a native ETH ↔ NEAR Bridge built by NEAR Protocol.

[Rainbow Bridge](https://ethereum.bridgetonear.org/) doesn’t physically transfer tokens between networks and instead utilizes a [smart contract](https://learnnear.club/how-the-near-rainbow-bridge-works/) to lock tokens on the Ethereum ecosystem and mint them on NEAR.

The NEAR Protocol already provides resources for you to use the [Rainbow Bridge](https://ethereum.bridgetonear.org/):

* You can check out an in-depth video walk-through on how to bridge your funds from Ethereum to NEAR [here](https://www.youtube.com/watch?v=zbmnITYLE-M).
* You can learn more about how [Rainbow Bridge](https://ethereum.bridgetonear.org/) works[ here](https://learnnear.club/how-the-near-rainbow-bridge-works/).

### Exchanging $NEAR with $DBIO/ $USDT.e <a href="#id-8a1a" id="id-8a1a"></a>

After you have bridged your funds to NEAR from Ethereum, you can use Ref Finance to exchange it with $DBIO tokens provided by the liquidity pools.

In the top right of the Ref Finance dashboard, click on the **“Connect to Near”** button.

Go to the Swap page by:

1. Clicking the **“Swap”** button on the navbar.
2. Choose $NEAR as your first token.
3. Choose $DBIO or $USDT.e as your second token.
4. Set the amount of $NEAR you want to bridge
5. Click **Swap**.

### Bridge From NEAR to the Appchain <a href="#id-8ab2" id="id-8ab2"></a>

To use your tokens within the DeBio Network Appchain, you need to bridge using the [Octopus Network bridge](https://mainnet.oct.network/bridge/near/debionetwork).
