Ok im wanting to do a direct buy from a trusted vendor, basically im asking how to get coins from coinbase to blockchain on tor. Step 1 buy coins on coinbase, step 2 send coins to blockchain on clearnet, step 3 do a shared send to blockchain on tor? is this how i go about doing this anonymously so i cant be linked to the wallet on tor?
I think I understand you're question.
Whether ordering on a market or direct with a vendor, you may use the method you are describing. In fact, that method is almost exactly how I do it.
[ ^ ] = click "Temporarily allow all on this page" in the NoScript add-on. I've never used Coinbase, but I assume it also requires scripts to temporarily be enabled. Don't allow scripts globally here.
[ * ] = click "Allow Scripts Globally (dangerous)" (Note: I have no idea why this is necessary for shared send, but not for regular send. As long as you have no sites open other than Blockchain, you should be fine)
The goal here is to have a clean wallet that is never used for illegal purchases; and a dirty wallet for darknet stuff. Shared Send acts to sever the tie between them.
