It is a next milestone in our history. We have implemented and tested hypergrid transactions and you do not need to be a resident of a virtual world to buy, sell or transfer coins. You can be a hypergrid visitor and have possiblity to use our service as a native avatar. Virtual world owners need to make a small change in their grid software and we will do the rest. Do not hesitate to contact us for more details!
We recommmend reading Maria Korolov article regarding this case.
