我们如何在 DEX 上狙击价值超过 5000 万美元的垃圾币
我们在去中心化交易所狙击山寨币赚取5000万美元的历程
2020年8月。我兄长在大学教授IT课程。我刚结束在保险公司担任产品经理的1.5年合约期。
加密货币市场低迷多年，正从新冠疫情引发的暴跌中缓慢复苏。我们在币安 Launchpad 项目中斩获几笔小胜，但投资组合总值仅勉强维持在5万美元。
这时我们听说了名为Uniswap的新协议。朋友们在那里炒垃圾币，常在几小时内赚到3-4倍收益。我们虽不知其原理，却隐约感到不同寻常。
有朋友向我提及“抢购”策略。他说bZx在Uniswap发行代币时，单个机器人就赚了50万美元。难以置信。我和哥哥震惊不已。我们想知道这究竟如何实现。
我弟弟对Solidity一窍不通，我们甚至不明白区块链的运作原理。
首次狙击行动
八月底。我们随家人在西班牙度假。几天前弟弟开始学习Solidity，因为我们打算尝试Uniswap狙击。
某代币即将上线：$YMPL。市场热度尚可。我们搭建抢购系统，邀几位朋友共同出资。毕竟我们是新手，不愿独自承担风险。
我们投入50 ETH（当时约合2万美元）。$YMPL上线后，成功抢购到8%的发行量。我登录Uniswap，30分钟内全部售出。
盈利？60 ETH（约3万美元）。当时我们整个投资组合还不到5万美元。我们欣喜若狂，感觉这钱来得太容易了。
我们想要更多。
两天后，新抢购目标：$VIDYA。这次我们用盈利追加了资金，首次胜利更让我们信心倍增。投入165 ETH，15分钟内盈利159 ETH。比上次更顺利。
四天后，新抢购机会出现。我们投入460 ETH，获利353 ETH，相当于13.5万美元。这是我们首次实现六位数盈利，耗时不足一小时。感觉简直爽翻了。
Uniswap正疯狂暴涨。交易量攀升，加密货币狂热者蜂拥而至。一切显得过于轻松，我们深知这不会持久。我们必须精进技艺，深入理解抢购机制的本质。抢购如何运作？团队要在Uniswap上线代币，必须向流动性池注入资金。此前抢购时，我们总在等待“添加流动性”交易上链后才下单，导致永远慢一个区块。
部分竞争者已能与流动性注入同步进入区块。
经过研究，我们发现通过以太坊节点可监控公共内存池，在交易上链前捕捉待处理信息。
自九月起，我们的抢购策略升级为：
- 实时监控内存池中的待处理流动性添加交易
- 立即发送相同gas费的买单
- 目标锁定在流动性添加交易后的同一区块内完成
以太坊抢购新纪元
2020年9月中旬。
经历十日平静期无新项目上线，正是升级机器人的绝佳时机。我们已蓄势待发。
但新挑战随之而来：暑假结束，我兄长仍在大学教授IT课程。有时抢购时机恰逢他授课期间。
所幸疫情期间一切转为远程教学。
当项目上线临近，他会对学生说：“请自行研究十分钟。”这便是他腾出时间管理抢购的策略。
下一个目标是$CHADS。我们已蓄势待发，准备投入200 ETH进行抢购。这轮抢购必将火爆，市场热度已达疯狂程度。
我和兄弟正通话中，紧张感爆棚。
他率先在终端捕捉到“添加流动性”交易。当机器人检测到时，他用严肃的语气宣告：
“Ça part。”（抱歉我们是法国人）
（意为“开始了”）
这句话将永远铭刻在我心中。每次狙击前他都会用一模一样的语调说出这句话，瞬间引爆肾上腺素。
听到这句话的瞬间，我像疯子般疯狂刷新以太坊区块浏览器，等待账户余额归零的信号——那意味着我们成功入场。
我们成功了。200 ETH。图表疯狂波动。我的任务是手动在Uniswap上抛售。
面对$CHADS的惊人数据，我双手颤抖、汗流浃背，视野完全收缩成隧道，只顾批量抛售以最大化收益。
最终盈利675 ETH（约27万美元）。感觉难以置信。但压力与肾上腺素让我们精疲力竭。
无暇喘息。三天后：$FRONTIER。相同模式，相同压力。盈利800 ETH。
两天后：$LINA。+80 ETH。次日：$CHARTEX。+700 ETH。
六天狂揽2300 ETH利润。简直疯狂。一个月前，我们投入加密货币领域多年，最高持仓仅10万。
9月18日带来惊喜：Uniswap空投。任何与Uniswap有过交互的地址均可参与。
由于我们进行了数周的大规模测试，最终积累了海量符合条件的地址。每个地址可获得约2万美元。记得我兄弟翻遍所有能找到的钱包，总共领到了六位数金额。
当月最后一次精准狙击目标是
——Polkastarter平台代币，该项目后来成为当年最成功的发售平台。
智能合约与基础设施升级
是时候再次优化我们的机器人了。
在最初的抢购阶段，我们采用限价策略：投入X ETH时，至少需购得Y枚代币。这种模式迫使我们分批交易——尤其当项目方流动性投放量难以预估时。
示例：
若项目方仅投放20 ETH流动性，而我们试图投入200 ETH，限价策略将失效。
我兄弟设计了新系统：每投入1 ETH，至少获取Y枚代币，并在达到限额前持续买入。我们是首个实现该系统的团队。
我们还面临另一难题：无法预知团队将以ETH、USDT还是USDC形式注入流动性。为此我兄弟开发了智能合约，无论上市交易对如何组合都能自动执行代币购买。
我们同时致力于提升交易机器人的运行速度。在$CHAD抢购中，我们虽全力出击，但流动性注入后显然未能成为头号抢购者。
我们在多地部署以太坊节点并让它们竞相抢购同一笔交易。很快发现北弗吉尼亚地区的节点始终更快。
这让我们确信北弗吉尼亚是运行抢购服务器的最佳地点。
经深入研究，我们的推测得到验证：
当时几乎所有用户都通过MetaMask进行交易，该钱包将所有“添加流动性”交易路由至Infura的公共RPC端点，而Infura服务器正位于北弗吉尼亚。
更广泛而言，大部分以太坊基础设施都集中于该区域。
因此，AWS北弗吉尼亚区被证实是抢购操作中最具竞争力且延迟最优化的配置方案。
我们还制定了完善的垃圾币抢购流程：
寻找目标垃圾币。我们通常有10-15位加密货币圈好友负责搜寻新晋热门垃圾币。若你率先发现目标，可参与抢购并获得15%的份额（同时承担风险）。部分成员通过发掘山寨币抢购获利30-70万美元。
锁定上线去中心化交易所（Uniswap/Sushiswap等）
确认上线交易对：ETH/USDT/USDC等
追踪负责上线的钱包地址（链上工作）
部署抢购智能合约并设定参数：规模与买入限额
上线后全数套现，通常30分钟内完成——毕竟多数币种都是狗屎
波卡启动器时代
10月至12月初市场沉寂。新项目发行放缓，我们一度以为抢购时代就此终结。我们已积累了可观的ETH储备，静待时机即可。生活很美好。
但十二月，山寨币市场卷土重来。Uniswap项目重启，新发售平台Polkastarter横空出世。
其首款发售项目是SpiderDAO。虽然每个钱包限购2.5 ETH，但弟弟发现这个限制只是界面显示，我们仍可直接通过合约大举扫货。几笔大额交易后，我们成功买下发行量的50%，并在上市时再次抢购。这次操作让我们赚了50万美元，我们回来了。
这个例子充分揭示了加密生态的本质。多数团队根本是无能之辈，对自身项目毫无头绪。这对我们反而是天赐良机，我们果断抓住机会大展拳脚。
部分DeFi项目开始推出合成资产，我们通过套利操作赚取60万美元利润。
12月成为我们人生的转折点——我兄弟辞去了大学教授的职位。
一月，我们移居迪拜，双双全职投身套利。
我们的理念很简单：机会出现就抓住。哪怕“仅有”1万美元收益，我们也全力以赴。深知这扇窗口不会永恒敞开，绝不放过任何一次机会。
一月我们再创数次捷报，包括$PAID和$PHOON，累计盈利达300万美元。
这些利润主要以ETH形式持有，而ETH价格从我们开始狙击时的200美元飙升至1月底的1400美元。短短五个月间。
反狙击措施
自2021年2月起，越来越多的团队开始为代币发行设计反狙击机制。人们已对狙击者忍无可忍（理由充分哈哈），并着手实施反狙击措施。
第一项措施：限额购买。
在代币上市的前几分钟内，每人仅能购买X枚代币。我兄弟率先设计出带循环机制的狙击智能合约。通过单笔交易，我们便能购入大部分上市供应量——每次循环都购买限额额度。凭借这个智能合约，我们真正做到了精准狙击，因为大多数竞争对手并未采用此策略。
我们的核心优势在于智能合约创新。我兄弟总能找到狙击技巧，而我们反而欢迎反狙击措施——这反而降低了我们的竞争压力。
第二项措施：钱包限额购买。
我兄弟设计了主从式智能合约体系。主合约每次购买都会调用新创建的子合约。
这些功能极为出色，在BSC狂热席卷月球币的未来数月将大显身手。
Polkastarter首发与竞争格局
自2021年2月起，Polkastarter时代正式开启。该平台发行的每枚代币均采用最大发送机制，为抢购者创造了七位数的盈利机会。
然而竞争正变得异常激烈。我们虽仍能获利，但竞争压力巨大。
为此我们设计了名为“自杀式抢购”的新功能。
原理很简单：我们发现许多投机者试图无限额抢购代币。我们的自杀式抢购功能会在每次抢购后自动追加一笔无限额交易，并在4个区块后自动抛售，以此套牢后续抢购者。
这并非改变人生的策略，但经常能带来50-150 ETH的收益。
后来竞争愈发激烈，有个代号0x887的家伙速度碾压所有人。我们耗费无数小时优化机器人，甚至定制以太坊节点追求极致抢购速度，连续数日反复测试。但永远无法超越这个神枪手。BSC恶性竞争季
此时已是2021年2月中旬。我和弟弟搬到了迪拜同一处住所。这相当令人惊喜，毕竟过去六年我们从未同城生活过。我们全职投机抢购，时刻寻找新机会，随时准备设计开发新项目。
即便竞争激烈，我们仍在以太坊上抢购。虽然仍在盈利，但我们深知这不会永远持续下去。
听闻BSC生态蓬勃发展，部分币种表现亮眼。我们决定在$80价位重仓布局BNB
2月16日，我们在BSC的首笔狙击目标是名为$BRY的垃圾币。当时对狙击策略和竞争态势知之甚少，正是实践学习的良机。
投入200 BNB。30分钟内全数抛售，获利800 BNB。盈利8万美元。虽不及以太坊的常规收益，但潜力可期。
第二次狙击目标为$MATTER
。投入75 BNB，套现2100 BNB。天啊！+2000 BNB利润。BNB表现同样强劲，二月底已涨至240美元。我们感受到惊人潜力。头号抢购者0x887似乎无意布局BSC。这简直是白捡的钱！必须锁定目标全额抢购。
三月是丰收之月。以太坊项目表现亮眼，我们成功赚取数百万收益。BSC网络更是疯狂暴涨。当月盈利达15000 BNB，其中$KPAD项目贡献8300 BNB利润。
至今仍清晰记得$KPAD——这是我们迄今最大的胜利。
当时我身处迪拜公寓。深知这个项目炒作热度极高，预感即将全面爆发。我紧张得汗流浃背，几乎不抱能参与的希望。团队名单公布时，BSCscan卡得要命。我切换到Pancakeswap查看余额，发现$KPAD数量多得惊人。卧槽！隧道视野模式启动。此刻的我只是MacBook前发光的自闭症患者。我抢到1%的配额，这价值连城。浑身发抖。全神贯注抢购。1小时赚200万美元。
五天后，名为$COOK的垃圾币在多链上线。我告诉兄弟：我们该把狙击战线集中在HECO链，因为竞争会非常少。代币在HECO上线时，我们以550 BNB买入。趁BSC链上无人解锁时，我们成功桥接至BSC，最大化套利获利3000 BNB。这感觉太爽了。
三月底，$BNB交易价达300美元。BSC基础设施与升级
四月初市场趋于平静。我们趁机前往马尔代夫放松。但刚抵达就听闻BSC即将涌现大量炒作币种，必须做好准备。
通过DeepL.com（免费版）翻译我们决定在BSC上进行速度测试。目前BSC的运作机制与以太坊不同。在以太坊上，你需要快速检测待处理的“添加流动性”请求，并迅速将交易发送至其他节点。
而在BSC上，几周前我们发现区块内交易的排序机制是随机的。当你发现待处理交易并发送新交易时，你的交易可能排在“添加流动性”交易之前，从而导致失败。
我们在AWS全球部署了10个节点，每个节点发送50笔交易尝试抢占随机测试交易。完成20批次测试后，我们分析了与“添加流动性”交易处于同一区块的交易数据。
由此得出以下结论：
- 表现最佳的节点位于北弗吉尼亚、法兰克福，偶见东京节点
- 仅前5-15笔交易能成功打入目标区块
- AWS最高配服务器能打入更多目标区块交易
后续抢单行动中，我们将在BSC构建150-200节点的基础设施。每个节点发送10笔交易。
运行此类基础设施的AWS月账单在4万至6万美元之间。
这对我的兄弟而言是个巨大挑战，因为他必须在150台终端上逐个启动节点。请记住，我们没有任何雇员或帮手，只有我和我兄弟两人。
我们在BSC拥有显著优势：既积累了以太坊的丰富经验，又愿意投入基础设施成本，这为小型抢购者设置了准入壁垒。
BSC的迷因币时代
我们目前全情投入BSC。有时一天要执行6次抢购，几乎无暇喘息，整天都在抢购垃圾币。我们永远在与时间赛跑，几乎没法优化系统——大部分时间都耗在设置新抢购任务上。
记得很多抢购案例，尤其$PINKM(Pinkmoon)那次：两小时内从120个钱包刷出300万美元，因为设有买入限额。次日我就买下了Aventador SV跑车。
2021年5月，两个BSC发售平台迅速走红。这些平台允许任何人执行上市交易。我兄弟率先设计并构建了智能合约，能在单笔交易中完成代币上市与购买。
如今这或许微不足道，但当时无人能做到。记得有周平台疯狂涌现，我们疯狂抢购，整整一周日赚七位数。某晚我与朋友在Nammos餐厅聚餐时，弟弟发消息说要去抢购某项目，待我回家时，账户已多出百万利润。
五月底，BSC平台热度开始消退，我们决定在$450价位抛售大部分BNB。
六月虽有零星抢购，但市场明显转冷。
抢购时代的终结反而令人如释重负——我们已精疲力竭，亟需休整。
整个夏天我们将周游各地，终于能好好享受生活。EVN大获全胜2021年8月，我们正享受夏日时光，加密货币方面没什么动作。只是处理些基础事务时，偶然发现被列入黑名单的钱包里还存着这些无法售出的$EVN代币。$EVN价格疯狂飙升，单个钱包里竟囤积着价值100万美元的代币（未计滑点损失——以太坊区块链上可见数据），而我们黑名单里明明有20多个钱包。
我们在Uniswap尝试首次出售200美元代币。成功了。我们心想“哇靠，说不定能分批抛售每个钱包的小额代币，或许能赚几千美元”
我们对同一钱包再次出售，竟获得2000美元。我们惊呆了，开始觉得这下午会很有意思。
接着清空该钱包所有代币：竟获得233 ETH（初始仅2.5 ETH）。
肾上腺素飙升，我们火速将所有黑名单钱包的代币倾销至Uniswap。部分钱包仍被封禁，部分却能正常操作——原因不明。疯狂抛售中，我们惊觉自己正以惊人速度创造数百万美元。
疯狂抛售15分钟后，我们将所有资产转移至冷钱包，预计收益约2-3百万美元。结果这个夏日午后竟凭空涌现出6百万美元。
我们至今仍搞不懂究竟发生了什么，也不明白这些钱包为何突然被白名单化。
本月我们还抛售了大量在3000美元上方狙击赚取的ETH，感觉是时候保障自由了。
结语
那年堪称我们迄今最疯狂的岁月。仅凭4万美元起步，对区块链运作一无所知，连Solidity语言都毫无概念。
我们总计在十余条链上狙击了200余种山寨币。能与兄弟共同经历这一切，实属无上荣幸。
那些难以言喻的情感波动与惊险刺激，至今仍历历在目。
感谢您读到这里。
祝您在自己的旅程中一切顺利。

How We Made +$50M Sniping Shitcoins On DEXs
August 2020. My brother is teaching IT at the university. I’ve just finished a 1.5-year contract as a product manager in an insurance company.
Crypto has been terrible for years and is slowly recovering from the COVID crash. We caught a few wins on Binance Launchpad, but our portfolio barely sits at $50K.
We start hearing about a new protocol called Uniswap. Friends are shitcoining there and are often catching 3-4x in a few hours. We have no idea what it is, but something feels different.
A friend tells me about sniping. He says that when bZx launched its token on Uniswap, a single bot made $500K. Unreal. My brother and I are shocked. We want to know how that’s even possible.
My brother knows absolutely nothing about Solidity. We don’t even understand how a blockchain really works.
The first snipes
Late August. We’re on holiday in Spain with family. My brother started learning Solidity a few days earlier as we want to try sniping on Uniswap.
A token is launching:$YMPL. Hype looks decent. We set up a sniping operation and ask a few friends to pool with us. We’re fishes and don’t want to carry the risk alone.
We go in with 50 ETH (~$20k at the time).$YMPLlaunches. We manage to snipe 8% of the listing supply. I log into Uniswap and sell within 30 minutes.
Profit? 60 ETH (~$30k). Our entire portfolio was under $50k. We’re euphoric. It feels like easy money.
We want more.
2 days later, new snipe:$VIDYA. This time, we have more funds from the profit and we feel confident after the first win. 165 ETH in. 159 ETH profit in 15 mins. Even better than last time.
4 days later, new snipe opportunity. We are in with 460 ETH. 353 ETH profit. $135k. This is our first 6-figure profit. In less than an hour. It feels fucking good.
Uniswap is blowing up. Volume climbs. Crypto degens are flooding in. It all feels too easy and we know it won’t last. We need to get better. We have to understand better how sniping actually works. How sniping works? To list a token on Uniswap the team must add liquidity to a pool. During previous snipes we watched for that Add-Liquidity transaction to hit the chain, and then we sent our buy which made us one block late.
Some competitors are getting in the same block as the liquidity add.
After some research, we realize that with an Ethereum node we can monitor the public mempool to see pending transactions before they hit the chain.
Starting from September, this is how sniping works for us:
Watch the mempool for a pending Add Liquidity TX.
Immediately send a buy TX with the same gas price.
Aim to be included in the same block right after the liquidity add.
New era of sniping on Ethereum
It’s mid-September 2020.
We’ve had ten quiet days without new launches. Perfect time to upgrade our bot. We’re now ready.
We have to face a new challenge though. Summer holidays are over. My brother is still teaching IT at the university. Sometimes, a snipe happens in the middle of his class.
Luckily, it’s COVID time and everything is remote.
When listings get close, he tells his students: “Do some research on your own for ten minutes.” That’s his way to be available to manage the snipe.
The next snipe is$CHADS. We are ready for it. We want to snipe it with 200 ETH. We know this one is gonna be a good one as the hype is insane.
I’m on voice with my brother. We’re nervous. Max pressure.
He’s the first to see the Add-Liquidity transaction appear on his terminal. When the bot detects it, he says in a serious tone:
“Ça part.” (Sorry we are French)
(meaning “It’s happening.”)
That line will stay with me forever. He says it before every snipe, with exactly the same tonality every single time, and it triggers an instant adrenaline rush.
As soon as I hear it, I start refreshing Etherscan like a maniac, waiting to see if our ETH balance drops to zero, the sign that we’re in.
We’re in. 200 ETH. The chart goes wild. My job is to sell manually on Uniswap.
With$CHADS, the numbers are overwhelming. My hands are shaking, I’m sweating, completely tunnel-visioned, just selling batch by batch to print as much as possible.
We close with 675 ETH profit (around $270K). It feels incredible. But we are exhausted from the pressure and adrenaline.
No time to rest. Three days later:$FRONTIER. Same setup, same stress. 800 ETH profit.
Two days later:$LINA. +80 ETH. Next day:$CHARTEX. +700 ETH.
2300 ETH profit in 6 days. Absolutely insane. 1 month ago, we had spent years in crypto with 100k maximum.
September 18th brings a nice surprise: Uniswap airdrop. Any address that interacted with Uniswap is eligible.
Since we’ve been running large-scale tests for a few weeks, we end up with a shit ton of eligible addresses. Each one gets around $20K. I remember my brother going through every wallet he could find and pulling mid–6 figures from it in total.
Our last snipe that month is
, the token of Polkastarter which will become the GOAT of launchpads later that year.
Smart-contract and infrastructure improvements
It’s time again to improve our bot.
During our first month of sniping, we had a buy limit such as: for X ETH, we want at least Y tokens. With this system, we had to make batches of transactions, especially because in most cases we don’t know how much liquidity the team is going to add.
Example:
If a team is adding only 20 ETH of liquidity and we try to buy for 200 ETH, our limit price is not gonna be right.
My brother design a new system: for 1 ETH, we want at least Y tokens and we will buy as much as we can until reaching this limit. We were the first ones to implement such a system.
We also struggle because we never know if the team will add liquidity in ETH or USDT or USDC. My brother design a smart-contract that will buy the tokens whatever the listing pair is.
We also work on improving the speed of our bot. During$CHADsnipe, we printed hard but we were definitely not top 1 sniper after the Add Liquidity.
We deploy Ethereum nodes in multiple regions and make them compete against each other to snipe the same transaction. It quickly becomes clear that nodes hosted in North Virginia are consistently faster.
This leads us to believe that North Virginia is the best place to run our sniping servers.
After conducting further research, our assumptions are confirmed:
At the time, nearly all users are transacting through MetaMask, which route every Add Liquidity transaction via Infura’s public RPC endpoint and Infura’s servers are located in North Virginia.
More broadly, most of the Ethereum infrastructure is concentrated in that region.
As a result, AWS North Virginia proves to be the most competitive and latency-optimized setup for sniping.
We also have a very process to snipe a shitcoin:
Find shitcoin to snipe. We usually have 10-15 crypto friends to look for new hyped shitcoins. If you find it first, you can join the snipe with 15% size (you also take risk). Some friends made between $300k and $700k profit from finding shitcoins to snipe.
Find on which DEX they will list (Uniswap, Sushiswap, etc.)
Find the listing pair: ETH, USDT, USDC…
Find the wallet that will list it (on-chain work)
Deploy the sniping smart-contract with parameters: size & buy limit
Jeet all after launch, usually within 30 mins as most coins are dog shit
Polkastarter era
From October to early December, not much is happening. New launches have slowed down, and for a moment we actually believe this might be the end of sniping. We’ve built a solid stack of ETH and we’re fine just holding it. Life is good.
But in December, the shitcoin market is back. Uniswap launches are back, and a new launchpad makes its debut: Polkastarter.
Its very first sale is SpiderDAO. There’s a buy limit of 2.5 ETH per wallet but my brother realizes that this limit is only on the UI and we can still ape directly through the contract. We send a few big txs and we manage to buy 50% of the sale. We also snipe it at listing. We make $500k profit from it. We are back.
This example tells you a lot about the crypto ecosystem. Most teams are absolute clowns and have no fucking clue about what they are doing. This is actually amazing for us. We can take advantage of it. And we go for it.
Some DeFi projects are also starting to emerge with synthetic assets, which we manage to arb for $600k profit.
December marks a turning point in our journey, as my brother decides to resign from his position as a university professor.
In January, we move to Dubai and both go full-time on sniping.
Our mindset is simple: if there’s an opportunity, we take it. Even if it’s “only” $10K, we go for it. We know this window won’t last forever, and we don’t want to miss a single shot.
We make a few more wins in January, such as$PAIDand$PHOONand manage to print $3M.
Most of these profits are held in ETH and ETH is max sending, from $200 when we started sniping to $1400 at the end of January. Only 5 months later.
Anti-snipe measures
From February 2021, we start to see more and more teams designing anti-snipe measures for their launch. People are getting tired of snipers (for good reasons lol) and begin implementing anti-snipe measures for their token launches.
First measure: buy limit.
During the first few minutes of a listing, you can only buy X tokens. My brother is the first to design a snipe smart-contract with a loop. In one tx, we are able to buy most of the listed supply. Every loop buys the limit amount. With this smart-contract, we really manage to nail it as most sniper competitors are not doing this.
One of our biggest edge is smart-contract innovation. My brother always finds a trick to snipe and we actually like anti-snipe measures because it makes it less competitive for us.
Second measure: buy limit per wallet.
My brother design a smart-contract with “slave” smart-contracts. The main smart-contract calls a new smart-contract for every buy.
These features are great and will be very useful in the next months as BSC mania goes wild with mooncoins.
Polkastarter prime and competition
From February 2021, this is Polkastarter era. Every coin launching on Polkastarter is max sending and is basically a 7 figs profit opportunity for snipers.
This is becoming very very competitive though. We still manage to make good profits but competition is tough.
We design a new feature that we call “suicide snipe”.
The idea is simple. We notice that many degens are trying to snipe coins without any buy limits. Our suicide snipe feature sends one more buy transaction without any buy limit and automatically sells 4 blocs after to catch everyone sniping after it.
This is not a life changing strategy but it happens very often to print 50-150 ETH from it.
At some point, competition becomes too wild and one dude known as 0x887 is just faster than everyone else. We spend hours and hours trying to improve our bot. We try to customize an Ethereum node to make it as fast as possible for sniping. We try and try and try for days. But we will never manage to be as fast as this sniper. BSC degeneracy season
This is mid-february 2021 now. My brother and I moved to Dubai in the same residence. This is quite amazing as we have not been living in the same city for the past 6 years. We are full-time sniping. Always looking for new opportunities. Always willing to design and build new stuff.
We are still sniping on Ethereum even if the competition is wild. We are still printing but we feel like it’s not gonna last for eternity.
We hear about BSC ecosystem doing great. Some coins are performing well. We decide to ape big in$BNB
at around $80 as we will probably need it to snipe anyway.
Our first snipe of BSC is a shitcoin called$BRYon 16 February. We don’t know much about the sniping meta or the competition. It’s time to find out.
200 BNB in. We sell all in 30 mins, 800 BNB profit. $80k profit. Not as much as standard profit on Ethereum but still. There is some potential.
Our second snipe will be$MATTER
. 75 BNB IN. 2100 BNB out. Holy fuck. +2000 BNB profit. BNB is also very strong and by the end of February, already trading at $240. We feel an amazing potential. Top 1 sniper 0x887 doesn’t seem to care about BSC. This is FREE MONEY for us. We need to lock in and snipe everything.
March is a very prolific month. Ethereum launches are great, we manage to print a few millions on it. BSC is going absolutely wild. We print 15000 BNB profit in March, especially on$KPADwith 8300 BNB profit.
I still remember well$KPADas this was our biggest win to date.
I’m in my apartment in Dubai. I know this launch is really hyped. I know this is gonna full send. I’m nervous. I’m sweating. I highly doubt we are going to be in. The team lists, BSCscan is laggy as fuck, I check on Pancakeswap and I see a shit ton of$KPADon the balance. HOLY FUCK. TUNEL VISION ACTIVATED. From now I’m just an autist on my MacBook. I jeet 1% of what we have and this is worth A LOT of money. I’m shaking. Fully focused on jeeting. $2M profit in 1 hour.
Five days later, the shitcoin named$COOKis launching on multi-chain. I tell to my brother that we should focus snipe operation on HECO chain because competition is gonna be very low. Token launches on Heco, we buy for 550 BNB. We manage to bridge to BSC while no one is unlocked on BSC. We max jeet for 3000 BNB profit. This feels SO GOOD.
By end of March,$BNBis trading at $300. BSC infrastructure & improvements
The beginning of April is calmer. We take this opportunity to travel to Maldives to chill. But when landing in Maldives, we hear about some BSC hyped shitcoins coming soon. We need to be ready.
We decide to run speed tests on BSC. At this time, BSC doesn’t work like Ethereum. On Ethereum, you need to be fast to detect the pending Add Liquidity and you need to be fast to sent your transactions to other nodes.
On BSC, we had realized a few weeks ago that the system to organize transactions within a bloc is random. When you detect a pending transaction and send one tx, your transaction can be before the Add Liquidity and then fails.
We setup 10 nodes on AWS all around the world and each node sends 50 txs trying to snipe a random test transaction. Once done on 20 batches, we do an analysis of the txs in the same bloc as the Add Liquidity tx bloc.
We draw a few conclusions from this:
The best nodes are located in North Virginia, Frankfurt and sometimes in Tokyo
Only the first 5-15 txs sent from one node manage to be included in the right bloc
The most expensive servers on AWS are able to include more transactions in the right bloc
For the next snipes, we build an infrastructure of 150-200 nodes on BSC. Every node sends 10 transactions.
The AWS invoices to run such infrastructure are between $40k and $60k monthly.
This is quite challenging for my brother to run this whole infra as he has to start nodes one by one on 150 terminals. Remember, we don’t have any employees or anyone to help us on that part. We are just my brother and me.
We have a great edge on BSC as we have a lot of experience from Ethereum and we are fine to spend money on the infrastructure, which creates entry barriers for the small snipers.’
Memecoins era on BSC
We are full focus on BSC now. Sometimes, we have 6 snipes in one day. We barely have time to live. We are just sniping shitcoins. We are constantly running after time, we barely have time to improve our setup as mot of our time is spent setting up a new snipe.
I remember many snipes. Especially$PINKM(Pinkmoon) when we printed $3M in 2 hours from 120 wallets as there was a buy limit. The next day I was buying an Aventador SV.
Two BSC launchpads are getting popular in May 2021. These launchpads allow anyone to execute the listing transaction. My brother is the first one to design and build a smart-contract that list and buy the token in the same transaction.
Today this might seem trivial but back in the time, no one was doing this. I remember a week when these launchpads were going wild and we would just snipe everything, making 7 figs a day for a whole week. One night I’m out with some friends having dinner at Nammos, my brother texts me that he’s gonna snipe one thing and when I come back home, we have $1M more profit.
End of May, things are slowing down on BSC and we decide to jeet most of our$BNBat around $450.
There will be a few more snipes in June but things feel quite bearish.
The end of this sniping era actually feels like a relieve as we are completely cooked and definitely need some rest.
We will spend the whole summer traveling around and finally enjoying. EVN win It’s August 2021, we are enjoying summer and not doing much in crypto. We are just doing some basic stuff and we randomly find a blacklisted wallet still holding these$EVNtokens we could not sell.$EVNhas been running like crazy and there are like $1m worth of tokens (not including slippage - displaying on etherscan) on just one wallet (we had +20 wallets blacklisted).
We try a first sell for $200 on Uniswap. Successful. We are like “wow wtf maybe there’s a way to dump a small part on every wallet, maybe we can make a few k”
We try a new sell on the same wallet and we get $2k. We are like wtf and we are starting to feel it can be a very interesting afternoon.
We try another sell, all tokens of the wallet this time: we get 233 ETH (initial was 2.5 ETH).
Adrenaline is kicking in and we are rushing all blacklisted wallets to jeet everything asap on Uniswap. Some wallets are still blacklisted and some are not. No clue why. We dump and we realize we are printing millions like brrrrrr.
After 15 mins of dumping as much as we can find, we send everything to the cold wallet and we expect like $2-3m from it. It was actually $6m out of nowhere on a summer afternoon.
We still have no fucking clue what happened and why these wallets have been whitelisted.
This month, we also sell a huge stack of our ETH earned from sniping above $3k as we feel like this is time to secure our freedom.
Conclusion
That year was probably the craziest one so far for us. Starting with just $40k and no real understanding of how a blockchain worked or even a clue about Solidity.
In total, we sniped +200 shitcoins on +10 different chains. Experiencing all of this with my brother was an incredible privilege.
We went through emotions and thrills that are almost impossible to put into words.
Thanks for reading this far.
Wishing you good luck in your own journey.
