The people checking out this post need to calm down. When you use steem keychain you input your masterpassword, but the tool doesn't save it. It breaks it into the smaller keys and saves those.
The whole point of keychain is so that you don't have to put your keys into any website. They are stored in the browser under encryption. The sites don't ever have access.
The comments are right, avoid putting your masterkey into any website. They don't understand steem keychain and how it's precisely to protect your keys.
Lastly, it's cool to have another gambling app on the platform. I'm glad you guys are here and looking forward to what you can build on Steem.
