As a rule, cryptocurrency operations and handling must take place within the parent openx platform. If platforms would like to add support for other cryptocurrencies, such functionality must be added to the openx repository to enable cross platform investments with the new cryptocurrency. This is to ensure that users in openx based platforms do not worry about security of the platform, and can refer to openx's central contract audits to build confidence in the platform. This is also to encourage the idea of open innovation where people can collaborate on building something useful.
