We are three weeks into the Nebulas Incentive Program, and the response from our developer community has been outstanding. Recently, noticed developers have a high enthusiasm for iterating on their DApps. Since Week 1, developers contacted us to ask about whether they can upgrade the DApps they have submitted.

Of course, releasing improved DApps benefits the creation of a healthy ecosystem. Therefore, we encourage developers to continue to optimize their applications. This article sets out our guidelines for developers on how to upgrade their DApps in a way that qualifies them for new rewards.

NIP considers the popularity of an application in the past week, and winners of the Weekly Third, Second, and Champion Prizes have the chance to compete for the Monthly Champion. We allow all previously submitted DApps to iterate and submit upgraded versions, to stand a chance at winning the top monthly prize. This means that, in the next few weeks, if you try to improve your rankings, you will also have a chance to compete for Monthly Champion award.

To submit an upgraded DApp, please follow these instructions:

1. If your previously submitted application has won the New Application Award, send the following to the email contact@nebulas.io, with “DApp Upgrade Request” as the subject email.

(1) The application name and contract address of the old version application.

(2) Your application must have all changes applied, such as application access URLs, contract addresses, application names, application descriptions, application images, etc.

We will review your new version and email the results. You can also see the results directly in the background of incentive.nebulas.io.

Special reminder:

1 An upgraded DApp is not considered as a new DApp submission, and will therefore not be eligible for multiple new application NAS awards.

2 After the new version is approved, the ranking algorithm will take the highest ranked address. Please submit it carefully so as not to negatively affect the rankings.

3 If the new version fails to meet requirements, and the information and status of the original version remain unchanged, you are encouraged to take noticed of our feedback and re-send the upgrade request email.

4 The deadline for the upgrade request is Friday at 24:00 on Beijing time. If the upgrade time has passed,, it will be processed in the next week.

5 It is recommended that upgrade requests be made for major changes such as access URL changes and contract address upgrade changes. If you resubmit your app directly and you don’t inform us that this is an upgraded version, it may affect the ranking result due to high code duplication or it may not be approved directly due to duplicate submissions.

Second, if the application you submitted earlier did not pass the audit itself, please resubmit the application without submitting the upgrade request. Your new version has the opportunity to win new application NAS rewards.
