I am writing smart contract and I test on rinkeby network. I have issued about 18 ethereums from faucet. But after a short time, there are 2 strange transactions: one getting 15eth and one getting 3eth from my account. Here is transaction detail:
My address is:
0x627306090abab3a6e1400e9345bc60c78a8bef57. You can view my transaction detail here (from the time I issue 18eth):
So, what is my problem here ? I afraid if "something wrong" and I don't know, I will lost more money on main network.
