Guidelines and Review Process
In January 2022, we opened the xApp development process up to the XRP community.
Anyone who would like to create their own xApp is now able to do so, but the created xApps will be 'sandboxed' ie. they can only be accessed by the developer.
This article is designed to assist you with this process and outline the steps required to get your completed xApp published in Xumm, so other users can open & use your xApp.
- 1.Review the guidelines to estimate your chance for success before coding or submitting your xApp for review.
- 2.Review initial questions that will be asked to determine if you can continue to finish the xApp before submitting the xApp for a final review.
- 3.Submit your code with a detailed explanation as to what your xApp does.
- 4.Our development team will;
- 1.review your code
- 2.test your xApp
- 3.if approved, the xApp will be made available through a direct, public URL available to all Xumm users.
#### Note::Please Note
This does not imply that your app will be listed in the Xumm "more xApps" section.
- xApps need to:
- add value to a significant share of the Xumm user base
- have clear instructions for end users
- be designed in a way that protects users from dangerous mistakes
- say what it does and do what it says
- have publicly available source code
- Keep it updated
- xApp developers need to:
- have gone through the KYC process
- provide both customer and technical support for their xApp
- have an easy and clear way to be contacted
- revoke any xApp from the Xumm platform without prior notice if it is deemed necessary to protect our users
Reasons for doing so may include (but not limited to):
- potential harm for users
- lack of customer support
- lack of updates
- promotes speculation (e.g. pushing users towards buying tokens is not allowed)
- involvement in any criminal activity or behavior detrimental to the XRP community
- Licensing issues/infringements
Make sure you review each question and thoroughly understand the purpose of your xApp.
