Someone Sold $12,000 worth of ZRX for $1 of ETH

I really like this one. I like it because the guy who got scammed thought he was scamming the scammer.

But it’s a harsh lesson. This mistake cost some unlucky person around $12,000.

Here’s what happened:

Some guy started a thread on 4chan’s /biz/ board saying he wanted to buy 50,000 ZRX tokens. At the time, these were trading for around 0.0008 ETH on the etherdelta exchange. The OP said he was willing to pay 0.003 ETH (so around 4 times the market value).

“Is anyone selling ZRX tokens? I’m buying 50000 for 0.003 eth ea”

He then posted a link to fill the order by using the 0x protocol. 0x is a decentralized exchange with no order book to look at.

“I’m buying at a ridiculous [premium to not have to deal with fucking etherdelta

you can literally buy more if you know how to use delta”

Buy the 0x tokens, transfer them to etherdelta, sell for a quick 4x profit. It sounds too good to be true.

And the OP soon realised his mistake – or at least pretended to.

OP realises his mistake


Someone reading the thread saw an opportunity to take advantage of the OP’s mistake and filled the order.

But he didn’t check the contract.

The contract wasn’t for 0.003 ETH per token. It was 0.003 ETH for all 50,000 tokens.

At the time, ZRX was trading for around 0.0008 ETH per token, or $0.24 in dollar terms. This means that the OP got over $12,000 worth of ZRX for around $1 worth of ETH.

It’s pretty clear in hindsight that the OP knew what he was doing all along. He posted a too good to be true offer and then pretended he’d made a mistake. But he knew someone would be keen to take advantage of this ‘mistake’ – and they did.

4chan reacts to the ZRX scam

The reaction wasn’t particularly sympathetic to the guy who got scammed. After all, he had been looking to take advantage of the OP – though not to quite the same extent.

The OP didn’t post again, nor did anyone in the thread admit to being the one who got scammed. We don’t know who it was, but I imagine he looks something like this:
