How I Snatched 153,037 ETH After A Bad Tinder Date

Over the weekend, I did a lot of swiping right. I’ve never had a Tinder go this fast from match to agreeing on a date time this fast before. I was thrilled! On the following Friday we went out. The evening started nice, but he got creepier and creepier by the hour. A few hours in, he’s a full-on creep. I had to bolt. Not a big deal — I prefer a night tracing scam ICO’s transactions anyway.

One of the bigger transactions originated from a multi-sig wallet smart contract. I don’t know why I did that, but I clicked in the Etherscan link and skimmed through the code.

Solidity is a shit language, so I wasn’t all that surprised. But, I mean, really? Wasn’t it so that you can call internal methods normally from derived contracts? I dunno, I’m not a Solidity programmer.

So I wanted to see how much of a moron either Gav/Nicolas or yours truly are, and decided to try it myself. I created wallet’s contract in my privatenet and referenced in another c...
