Thanks very much
@alwsyoung You have to open the server in your archive console, if you put this: python -m http.server
Then you go to chrome, firefox... etc and search localhost:8000
Its like emulate the web conection, if you think that, you are trying to conect metamask with nothing.
It does not work! i can't connect metamask, nothing happends
my task is when we click on metamask wallet button metamask extention will open ...
i am fresher i dont know how to do it please help me
This is grate intro , but unsecured as hell... I just create extension that creates window. , not taking that data are added to windows params , but they are requested over script received over body (unclean playground to test it out : https://gist.github.com/shivergard/a9c0c0d18303e9b304876ded604f77f8)
is there are any secure sample around ?
same problem @dynamo-foundation got like, did some one know how to fix ?
