I tried to configure my account called splinterlandspro to delegate assets to the main account called viniciotricolor.
https://api.splinterlands.com/players/reward_delegations?username=splinterlandspro
According to the API, it seems to be configured correctly. I don't know if one thing out of the ordinary is that it starts with [ and ends with ]. I'm not sure if this is normal or not.
I also have a question about how it works. Does it send assets automatically? Do I need to do something to start it, or does it work automatically at intervals of hours?
