Hi, I don’t understand how callback must be used in the balance_of entrypoint. Can someone give me any example? Thanks
Getter contract here gives an example: the
getter entrypoint calls
balance_of and then the
_setter entrypoint receives the callback.
Thanks for answer.
I have already seen that but i don’t totally understand what actually the callback is or does.
Can you help me with a easier example?
The callback is a transfer of 0 tez done by the FA2 contract to the entrypoint given to
The associated argument is a list of requests (owner and token_id) and response (balance).
The list contains the exact same requests (in the same order and without de-duplication) as given in the
balance_of parameter and it associates an answer: the number of tokens owned by the owner for the given token id.
Ok now i understand! Thanks
