#Overview

The Content Security Policy (CSP) of a browser dictates what resources can load. Magic maintains a predefined list of RPC URLs in the CSP. You can find these RPC URLs in the page relevant to your chosen blockchain. If you are using a Dedicated Wallet, you can update the policy on the Settings page of the dashboard with a custom URL.

#Use cases

• Use the connect-src directive to allow specific URLs, such as a custom RPC URL to send transactions to your node

#Usage

When connecting to a custom RPC node, ensure that the URL you use in your code has been added to the CSP in your Magic Dashboard.
