In Chrome, the homepage is either the actual URL or the New Tab page.
So this will be chrome://newtab/, except that if you try this on the page, you will raise this security error:
Unable to load local resource: chrome: // newtab /
(see bug in Chrome Developer Tools)
So, I do not think this is possible. I could be wrong, I'm not an expert in Chrome.
chrome://newtab/ , , .
