Hello,
I have some questions regarding payvault security.
1. the only way to implement payvault in your game is via client like in this linkhttp://playerio.com/documentation/payvault/provider/paypal:? No serverside.
2. this is secured because if someone hacks your game he can only modify the coin amount he wished to purchase, but this is set up by me in the payvault interface so he can't get 1000000 coins for 0.01 $?
Thanks.
