all in the title

Just grant them the permission: economics.transfer -- Allows player to use the transfer command

no it's not that, I want to know if there is a way to see the transfer, like in a log

Ah, I thought your title had "Set", not "See"; in that case, no there is no logging right now, but you could use a plugin such as Logger to listen for the command you want to log.

oh thank you !! :)
