Terms of Service

Last updated: September 2026.

1. What Wasit is

Wasit is an open-source conformance tester for the x402 and MPP (Machine Payments Protocol) payment protocols on Stellar. It ships as a CLI, an MCP server, and a shared core library (@wasit-dev/cli, @wasit-dev/server,@wasit-dev/core), published to npm under the Apache License 2.0. This website is documentation and a landing page for that project — it is not a paid product, an account-based service, or a custodian of funds.

2. Open-source license

The Wasit source code is licensed under the Apache License 2.0. That license, not this page, governs your rights to use, modify, and redistribute the code. If the two ever conflict on a code-licensing question, the LICENSE file in the repository controls.

3. No warranty

Wasit is provided “as is,” without warranty of any kind, as stated in the Apache 2.0 license. It is a testing tool: it inspects and runs real payment flows (including on-chain settlement checks) against services you point it at. You are responsible for running it against services you are authorized to test, for reviewing what a check does before running it with --allow-destructive or similar flags, and for any funds moved by the flows it exercises. Wasit’s maintainer is not liable for losses arising from its use.

4. Using this website

You’re free to browse and link to this site. Please don’t attempt to disrupt it (scraping at abusive rates, attempting to break the hosting, and similar) or use it to distribute malware or misleading claims about the project.

5. Third-party services

This site is hosted on Vercel and its source is on GitHub; the published packages are distributed via npm. Your use of those platforms is governed by their own terms, not this page.

6. Changes

These terms may be updated as the project evolves. Material changes will be reflected by updating the date at the top of this page.

7. Contact

Questions about these terms can be raised as an issue on GitHub or via X.
