I am studying Smart Contract with solidity. I can't understand something, so I want to get expert advice.
I logged in to the Upbit exchange to trade the golem's token. The Upbit exchange gave me a token deposit address. That address was a contract address(0x27c6769A0549fa03DafEd89d555C7E71B21Dd35E)
After depositing the golem's token, something happened that I could not understand. There is no ether to pay for the gas at the deposit address, but the golem's token was transferred to another address.
Q1] To transfer tokens without Ether, how to implement smart contract?
Q2] If you know where to find the sample code to reference, I would like to know the url
