Please make sure that you are also submitting your entry through the G4C Portal https://g4cstudentchallenge.secure-platform.com/a/organizations/main/home as only submissions also submitted through their platform will be considered for the prize funding. G4C will coordinate with winners on how the prize is awarded. However, as it is a global challenge, they are well aware that many of the participants are not US based and they have experience working with folks with various different forms of payment processes around the world.
