# Third-Party Extensions

> Community-maintained libraries and integrations for StellarX402.

Community libraries built on top of the StellarX402 protocol and SDKs. They are not maintained by the StellarX402 team; check each project's health before depending on it in production.

If you have built something you would like listed here, open a PR on this page.

## Wallets that ship x402 support

## Vetting a third-party integration

Before depending on any of the above in production:

* Confirm it has been updated against the current facilitator minor version.
* Run the [buyer quickstart](/getting-started/quickstart-buyers) or [seller quickstart](/getting-started/quickstart-sellers) end-to-end using it.
* Check that its error handling maps to the [standard rejection codes](/reference/error-codes).
