truffle migrate -f 2 --network rinkeby. Then, I navigated to https://rinkeby.etherscan.io/address/[ADDRESS_OF_DEPLOYER]
And I got two TXs:
The second TX is clear since
To equals to "Contract Creation". Now, what is the first TX? The
From is the same as the second TX, however, the
To is another address (0xb52078acf139....).
