Im a web developer, im trying to code a feature that upon completion of a task, a user is credited with a set amount of tokens to his wallet. Basically a reward in ETH upon demand of the server, is there a way i can do this? Do i need to have a centralized wallet which will send coins to the user, if so is there an API? Otherwise is there a simpler way to do this such as directly getting the coins from the blockchain?
Thanks in advance
