I am trying to modify the price in mini cart with a custom product attribute

now the price in the minicart come from:


and look like this

<div class="price-container">
  <span class="price-wrapper" data-bind="html: price"></span>

So, somehow the price is binding.

Does anyone know where this price is binding? or in which part of the code the mini cart product attributes are render?

    First extend checkout module , on debug mode and you will see all files rendering for price. Please post more details what changes you required in price so that community can answer you question.

You can follow these steps to resolve the minicart price issue-

STEP.1 Create events.xml file at app/code/YourNamespace/YourModule/etc/frontend

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="checkout_cart_product_add_after">
        <observer name="custompricemodule" instance="YourNamespace\YourModule\Observer\CustomPrice" />

STEP.2 Create CustomPrice.php file at app/code/YourNamespace/YourModule/Observer

namespace YourNamespace\YourModule\Observer;

use Magento\Framework\Event\ObserverInterface;
use Magento\Framework\App\RequestInterface;

class CustomPrice implements ObserverInterface

public function execute(\Magento\Framework\Event\Observer $observer) 

        $item = $observer->getEvent()->getData('quote_item');         
        $item = ( $item->getParentItem() ? $item->getParentItem() : $item );
        $price = 600; //set your price here
