py-order-utils
Python utilities used to generate and sign orders from Polymarket's Exchange
Decision gist · record as of 2026-08-14
Yes, if you are actively building on Polymarket and need order signing. The library is permissively licensed, has low install friction, and carries no known vulnerabilities. However, dormant maintenance (last update 2024-07-29) means you should verify compatibility with the current Polymarket API and Ethereum tooling before committing to production use.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python >= 3.9.10 and a private key or account to instantiate the Signer.
- Low install friction with a pure-Python wheel.
- Maintenance is dormant—last commit was 2024-07-29 and no releases since the first release on 2022-02-03—but the repository remains active and unarchived.

What it is and what it does
py-order-utils is a Python library for constructing and signing orders on Polymarket's CLOB exchange. It wraps the order-building and EIP-712 signing logic needed to prepare orders for submission to Polymarket's API, handling the cryptographic details through dependencies on eth-account, eth-utils, and poly-eip712-structs.
The package is designed for developers integrating Polymarket trading into Python applications. It provides an OrderBuilder class to construct order objects and a Signer class to cryptographically sign them, then serializes the result to JSON for API transmission. The library requires Python >= 3.9.10 and depends on Ethereum signing primitives.
Use it for
- Build and sign limit orders programmatically for Polymarket prediction market trading.
- Automate order submission workflows that require cryptographic signing before API calls.
- Integrate Polymarket trading into a larger Python trading bot or portfolio management system.
- Generate properly formatted order and signature JSON for direct CLOB API consumption.
