Polymarket SDK v0.4.0 is officially released 🎉 Thanks for all the support — we’ve reached 580 stars already! github.com/cyl19970726/poly-… In this release, we also implemented a 15-minute market strategy. Feel free to use it if you’re interested. Strategy Overview (15-Minute Markets) The core idea is simple: Leg 1 (Entry): Detect a sharp crash (e.g. 30% drop within 3 seconds) and buy immediately. Leg 2 (Exit): When the price reverts to a more rational level, sell to lock in profit. Leg 1 Parameters slidingWindowMs: 3000, // 3 seconds dipThreshold: 0.3 // 30% dip With these settings, if the market drops 30% within 3 seconds, the bot will buy automatically — regardless of YES or NO. Leg 2 Parameter sumTarget: 0.95 This means you can spend 0.95 USDC to obtain both UP and DOWN shares (worth 1 USDC). Risk Control We also added a stop-loss mechanism: leg2TimeoutSeconds For example, if set to 100, and Leg 2 hasn’t executed after 100 seconds, the bot will automatically sell the Leg 1 position to prevent it from going to zero. Capital Efficiency Improvements Auto-merge support: After completing Leg 2, positions are automatically merged back into USDC.e, significantly improving capital efficiency. Auto-rollover: After each 15-minute market ends, the bot automatically enters the next market. Any remaining positions will be redeemed once the market allows redemption. So in practice, you can just let it run — though parameter tuning matters a lot. Different parameters produce very different results. We strongly recommend avoiding overly aggressive settings. With fees now applied to 15-minute markets, high-frequency strategies are even less suitable. Large Orders If you’re trading large sizes, you can use splitOrders, which automatically splits a large order into multiple smaller ones. Architecture Updates Added a Binance service Fixed the issue where only YES/NO was returned in previous versions More details are available in the codebase.

🚀 Polymarket SDK v0.3.0 is out! Thanks for all the support — the repo has reached 352 stars ⭐️ github.com/cyl19970726/poly-… @Polymarket You can now implement copy trading in just 10 lines of code. Our new architecture: Tomorrow I’ll go deeper into what’s new in v0.3.0 — beyond the new Smart Money Service, there are several other important updates. That’s all for today — getting some rest now. Good night 😴 If you’re also interested in arbitrage, check my previous tweet — it includes a complete implementation you can directly reuse.

Polymarket SDK 0.3.0 发布了,感谢大家支持现在已经有 352个star了 github.com/cyl19970726/poly-… @Polymarket 现在你可以用 10 行代码做跟单了 原理如下： 我们的新架构： 明天我在来说下v0.3.0 除了增加了 smart money service 还做了哪些更新，今天困了先睡了晚安。 以及如果你还需要做套利可以参考上条推特，都有完整的实现，需要自取吧。

Yesterday I open-sourced polymarket-sdk for @Polymarket github.com/cyl19970726/poly-… Thanks for the support — the repo already has 223 stars and 63 forks ❤️ Today, we shipped a major update. The SDK now covers almost everything you need to build on Polymarket: 🔄 Real-time arbitrage detection (WebSocket-based) 📊 Smart money analysis — track top traders and strategies 💱 Trading integration (GTC / GTD / FOK / FAK) 🔐 On-chain ops: split, merge, redeem CTF tokens 🌉 Cross-chain deposits from Ethereum, Solana, Bitcoin 💰 DEX swaps on Polygon (QuickSwap V3) 📈 Market analytics: K-lines, signals, volume Today’s highlight: ArbitrageService 👀 We now officially support Polymarket arbitrage. The idea is simple: - If buying a YES NO pair costs < 1 USDC, buy both and redeem on-chain - If selling a YES NO pair yields > 1 USDC, mint a pair for 1 USDC and sell The hard part is execution. In real markets, arbitrage windows are short — there’s often no time to do on-chain actions when profit appears. So the ArbitrageService uses dynamic position management: - Maintain USDC ↔ YES/NO positions - Keep USDC ratio between 20%–80% - Always ready to buy or sell immediately when opportunities show up Handling partial fills Partial fills are inevitable and can leave you with unbalanced YES/NO positions. The service automatically: - Sells the excess side - Keeps YES and NO close to 1:1 - Exposes a settlePosition helper to clean up exposure anytime Full arbitrage theory implementation details are documented in the repo.

承蒙大家厚爱，polymarket-sdk 仓库现在已经有 129 个 star 和 37个fork. 开源YYDS! github.com/cyl19970726/poly-… @Polymarket 今天更新了下架构，基本上你在polymarket上需要的所有操作这里都提供了对应的方法，比如存钱，Swap,Search Market,以及给大家提供一个ArbitrageService,大家如果想做套利可以用这个进行套利尝试。 ArbitrageService： Polymarket Arbitrage简单来说： 就是如果 Buy Pair(yes,no) 的成本小于 1USDC,那么你可以同时买1yes和1no，然后去合约里换回1USDC, 这样就可以赚一个价差。 相反如果 Sell Pair(yes,no) 大于 1USDC, 那么也可以去合约里花1USDC mint 1 Pair(yes,no) 然后卖出同样也可以赚取价差。 但是在实际的套利过程中，利润产生的那个时刻，其实是没有时间给你去链上操作合约的，所以我们在实现套利服务的时候采用的是动态仓位，就是USDC : Pair(yes,no) 的比在20%~80% 之间从而保证我们出现 Sell的机会有Pair(yes,no)可以Sell,出现Buy的机会有USDC可以买入. 以及因为套利很多时候会有一个严重的问题，就是往往你只能部分成交，所以可能出现 (YES,NO) 数量不是1:1 的情况，这里我在套利服务里使用了比较简单的办法处理，看就是卖掉多的那一个token，保证YES跟NO 1:1 以及也实现了帮你随时情况仓位的 settlePosition 功能等等 关于Polymarket完整套利原理，我在仓库的文档里也写了完整文档，需要的朋友可以自取github.com/cyl19970726/poly-…

写了一个 polymarket-sdk 把 @Polymarket 的所有api 接口都封装了一下。 并且在API接口的基础上提供了，K线 接口，套利检测，缓存，orderbok 自动排序等等，需要的自取吧： github.com/cyl19970726/poly-… 架构如下：
