# User Guide: Non-custodially BTC Staking (via Script)

## Step 1: Create a Merge Order via Web UI

Go to [Merge Marketplace](https://app.b14g.xyz/marketplace) and connect your EVM wallet (OKX wallet).

On the main screen, find and click the **‘Create Order’** button.

{% stepper %}
{% step %}

### Set reward sharing allocation and Create order

Enter the percentage of rewards you want to keep, and the remainder will go to future CORE holders.\
\&#xNAN;*<mark style="color:green;">Please keep in mind that the reward shared portion only applies to the additional rewards gained through CORE dual-staking. Your original BTC staking rewards stay yours and aren’t affected.</mark>*
{% endstep %}

{% step %}

### Copy Reward Address

Reward Address on Core chain (aka **Order address**) will be used to add to BTC staking script in the next step.
{% endstep %}
{% endstepper %}

{% hint style="warning" %}
Each order corresponds to one BTC lock. If you want to execute multiple BTC locks, you'll need to create multiple orders.
{% endhint %}

## Step 2: Run BTC Staking Script

Staking on b14g follows Core’s non-custodial BTC staking model. You can use CoreDAO’s BTC staking tool here: <https://github.com/coredao-org/btc-staking-tool>.

{% hint style="info" %}
Just make sure to **replace the reward address with the order address in Step 1.**
{% endhint %}

{% code overflow="wrap" %}

```
// BTC Staking Script

node dist/index.js stake --account tb1qzdvhlak7y8kz0v5hu2tw7qae3969jzrt7rj7n5 --privatekey ${private key} --amount 1000000 --bitcoinnetwork 1 --corenetwork 1 --locktime 1712847585 --rewardaddress ${Order Address} --validatoraddress ${Validator Address}
```

{% endcode %}

{% hint style="success" %}
**That’s it!** Your order is now live. Wait for CORE holders to match with your BTC to enable dual-staking.
{% endhint %}

{% hint style="info" %}
**Why haven't my merge order shown up in marketplace?**

As with all blockchain transactions, it's not instantaneous. Bitcoin deposits take about 6 blocks to confirm. Once confirmed, your order will appear in the marketplace.

Visit the **‘My Portfolio’** tab to view your created orders.
