A new package, payitgo 0.2.0, has been published on PyPI — a Python client for a crypto payment gateway. On its own it's a technical event, but it directly concerns anyone who sends or accepts crypto payments through third-party libraries: every such dependency is a potential entry point for key and credential theft.

What the package is

payitgo is a Python client library that simplifies integration with a crypto payment gateway. It lets developers work with the gateway API: create invoices, check transaction statuses, retrieve payment data. Version 0.2.0 is early — which is itself a signal: the code is young, may not have been audited, and the community hasn't vetted it for security yet.

Why it matters for wallet holders

If you use third-party libraries to work with crypto, you trust them with access to API keys and sometimes private keys. The main risks:

  • API key leaks. If the library sends keys to a third-party server or logs them, an attacker gains access to your account.
  • Recipient address substitution. Malicious code can swap the wallet address when building a transaction — your funds go elsewhere.
  • Hidden telemetry. The package may collect data about your transactions and share it with third parties.
  • Trojan dependencies. Even if the package itself is clean, its dependencies may contain malicious code.

How to protect yourself with new libraries

A few practical steps that reduce risk:

  • Verify the source. Download packages only from the official PyPI, check the author name and repository. Similar names are a common typosquatting trick.
  • Read the code. For early versions (0.x) this is a must: check where data goes and whether there's obfuscation.
  • Isolate the environment. Run integrations in a separate virtual environment or container without access to your main wallets.
  • Limit API key permissions. Create keys with only the needed scopes (e.g., read-only or invoice creation only) and no withdrawal rights.
  • Enable 2FA on your exchange and payment gateway. Even if a key leaks, without the second factor an attacker can't withdraw funds.
  • Monitor transactions. Set up alerts for any account activity.
Simple rule: the younger the library and the broader its access to your keys, the more carefully you should vet it before using it in production.

What to do if you already use similar packages

Audit your dependencies: update them to current versions, remove unused ones, and check for suspicious updates. If in doubt, revoke old API keys and create new ones with limited permissions. For large sums, use a cold wallet rather than a hot one with API access.

FAQ

Is it safe to use payitgo 0.2.0?

Decide after your own code audit and repository check. For production, early unaudited versions are a risk.

How can I tell if a library is stealing keys?

Look for network requests to unknown domains, logging of sensitive data, and obfuscated code. Test in an isolated environment.

What to do if I suspect a leak?

Immediately revoke API keys, change passwords, enable 2FA, review transaction history, and contact the gateway support if needed.
