Phantom Wallet Blocking unpkg.com Access Within n8n Workflow

I am running an n8n workflow and have the Phantom browser extension wallet installed and active. Upon executing a specific node or opening the workflow editor, I receive a security warning from Phantom blocking access to unpkg.com.

This is causing an interruption in my workflow, and I am concerned about the security implications, despite n8n being a well-known platform.

Phantom Security Warning Details

The exact message displayed by the Phantom extension is:

unpkg.com is blocked! Phantom believes this website is malicious and it is unsafe to use. This site has been flagged as part of a community-maintained database of known scams and phishing websites. If you believe this site was marked erroneously, please submit an incident. Ignore this warning and take me to unpkg.com anyway.”

I expect the n8n workflow to execute or load without triggering a security warning from a major cryptocurrency wallet extension like Phantom.

Specific Questions for the n8n Community

  1. Has anyone else experienced Phantom or other crypto wallets (like MetaMask) blocking unpkg.com while using n8n?

  2. Is there a known package or dependency in n8n that relies on unpkg.com that could be causing this false positive?

  3. If this is an n8n dependency, what is the best practice for securely loading it without disabling my wallet’s security features?

I am seeing the same error when downloading from unpkg.com with Phantom Wallet installed:


This is bad.

We download the CSV templates from our npm package from unpkg.com

Would you consider removing unpkg.com from your block list, and instead switch to blocking specific npm packages instead?
