EMN Post-Mortem
So. First, the official post-mortem by Andre:
https://twitter.com/AndreCronjeTech/status/1310763506170499072. Let him frame the narrative without me doing the subjective side.
Now my context: Andre deployed some contracts, they had a few tokens and interesting designs with a bonding curve. It was deployed from the Yearn Deployer, so some smart/opportunistic people noticed it right away. Me included. I put in, but the mathematician guy said the slope was flat, so I sold. You can check ivangbi.eth transactions. But damn, I was so enthusiastic about some new deployment and bonding curve stuff - but it seemed like the design was way too user-focused, aka no ponzi/pumpenomics. Saaaad, right.
The contract had back then about 25K Dai total:
https://etherscan.io/address/0x5ade7ae8660293f2ebfcefaba91d141d72d221e8. A few hours later, someone noticed that the price was actually kinda going up harder... checked: fuck, it was aping. The contract had about 100K then. So I go and put in more. Lobsters do, it was all public. We see prices are going stronger than we thought. And damn, the fomo started. I bought more at about 500K AUM, then 1M AUM, and actually... at the top of 17M AUM was my 40% purchase lol. But we will get to that later.
Some game Dynamics 🕹
So they all use Bancor Bonding Curve -

And this is what we calculated wrong as being flat, as the total reserve balance actually is a more complicated math than a Uniswap formula (or, different). So then you have two main tokens: EMN and GIL, both on a curve with Dai. GIL is a thing for minting STR which is like a power boost for the cards in the game. And EMN mints eSNX, eYFI, eAAVE, eCRV, eYFI as factions. So two tokens with direct Dai curve, and other ones as a 1-hop... and there is likely more, we barely saw anything yet. So yes it's fun to play with contracts, being early on every curve, and so on! And let me point out that yes, this is a zero sum game at first glance, but obviously it's Andre and we all expected/knew that more cool stuff is coming. Cause it was/is. And it’s part of the game.
PS 🃏 it's apparently some cool NFT multiverse game with cool backend mechanics and fractions. With some gamedev shops included. It was all supposed to come later.
Now to the price part ☠️
AUM at 17M, I buy 40% more, and 5 minutes later - a few market sells making the AUM drop to 12M. I am a panic seller and a pleb. What do I do? I pack losses on eTokens and sell at small profits anyway. By far not what I would have had, but enough to get a nice laptop after 6 hours, a lot of fun, and fun-ethereum interactions. I am then on a call with Klim and Artem, who aped in around that price again, and they are making fun of me being a pleb. Everyone knows that when I sell - freedom is coming. So I finish selling, and we go to sleep...
And then 5min later the AUM goes back to 15M, I already message in the chat that I am rekt and thinking of buying back. And then bam: it's empty. Just empty, all gone:
https://twitter.com/IvanGBi/status/1310752541240590336. Yes, all 15M Dai evaporated. A flashloan type of attack (still need to understand the math) pocketing the entire Dai pool and rekking everyone:
