That's an issue we you need to resolve. We were working with HunnyPlay, they are planning to integrate BTC with their system. Maybe looking at their idea you may find a solution. Sorry, I have very limited knowledge about smart contracts and how the tech works. My understandings are sometimes below than average.

By the way, according to the forum rules, you can not make consecutive posts in a row within 24 hours. You need to wait until there is a new response. However you can edit a post and response as many as you want.
