Polymarket bot GitHub & npm risks

A repository or package listing is not a security audit. Before running third-party Polymarket code, establish who maintains it, what it installs and which account permissions it needs.

This checklist does not label a particular project as malicious or claim a measured rate of unsafe tools. It is part of the Polymarket trading bots handbook.

Distinguish keys and credentials

Polymarket’s key guidance says not to share a private key with another party. Its API documentation distinguishes wallet signatures from API credentials: public market data needs no credentials; private trading operations require authentication and order authorization.

Review before installation

  1. Identity: follow links from official documentation when choosing an official SDK; verify the repository and package names.
  2. Installation: inspect dependencies and install scripts before running code. Open-source availability alone does not establish safety.
  3. Permissions: document whether the tool needs public data, private account data, trading authority or withdrawal capability.
  4. Secret handling: identify where credentials are stored, logged or transmitted. Do not paste a wallet key into a third-party form or chat.
  5. Control: understand how to stop the process and remove the access it uses before connecting an account.
  6. Scope: check the US or International path and test the risk controls.

If credentials may have been exposed

Stop using the untrusted tool. Use independently verified wallet or platform controls to review activity and secure the affected account. Do not rely on instructions supplied by the suspected tool. Revoking an API credential is different from securing a disclosed wallet private key.
