# Custom Linking

> Create shareable swap links with your referral code—no coding required

Create custom deBridge links with pre-filled parameters and your referral code. Share them anywhere—social media, blog posts,
Discord—and earn from every swap.

## What You Can Do

* Create links with pre-selected chains and tokens
* Embed your referral code to earn [deBridge Points](/home/monetization/debridge-points)
* No coding or technical setup required

<Note>
  Your referral code only applies to **new users** who have never visited deBridge before and haven't made any transactions
  through the protocol. Existing users won't be counted as your referrals.
</Note>

## Step-by-Step Guide

<Steps>
  <Step title="Generate Your Referral Code">
    Go to [app.debridge.com/refer](https://app.debridge.com/refer)

    1. Connect your wallet
    2. Select **Polygon** (cheapest option, works for all chains)
    3. Click **Generate**
    4. Save your referral code (e.g., `7895`)
  </Step>

  <Step title="Create Your Custom Link">
    Start with the base URL and add your referral code:

    ```
    https://app.debridge.com/?r=YOUR_CODE
    ```

    Example with referral code `4850`:

    ```
    https://app.debridge.com/?r=4850
    ```
  </Step>

  <Step title="Add Optional Parameters">
    Customize the link further by pre-selecting chains and tokens.

    Example: USDC on BSC → USDT on Ethereum with referral code:

    ```
    https://app.debridge.com/?inputChain=56&inputCurrency=0x8ac76a51cc950d9822d68b83fe1ad97b32cd580d&outputChain=1&outputCurrency=0xdac17f958d2ee523a2206206994597c13d831ec7&r=4850
    ```
  </Step>

  <Step title="Share Your Link">
    Post your custom link on Twitter, Discord, Telegram, or your website. New users who swap through your link will contribute to your points.
  </Step>
