Polymarket SDK v0.4.0 is officially released 🎉
Thanks for all the support — we’ve reached 580 stars already!
https://t.co/jcNbpdyEat

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 ⭐️
https://t.co/jcNbpdyEat
@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
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
https://t.co/jcNbpdyEat

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.

@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https://t.co/gBiKosFx6W

[0xhhh @hhhx402]

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：
