Application Title

JavaScript SDK and related projects development Q4-2023


Denis Davidyuk – GitHub

Value Application

JS SDK is actively used by onboard and community developers. Some use cases raise features that need to be implemented on the SDK side, the same as bugs that need to be fixed. Dependent projects may contribute to SDK and these contributions need to be reviewed. This proposal is intended to solve these requests firstly, to keep the development of dependent projects efficient.

Additionally, there is a set of things that are known to be good to have, the most important of them are:

Definition of Terms

JS SDK aka @aeternity/aepp-sdk is an NPM package that implements basic functionality for web-based aepp to communicate with aeternity blockchain and to access user accounts provided by the wallet.

Status Quo

I released @aeternity/[email protected], including bug fixes and non-breaking features from the previous grant.

Required Work

After Ceres protocol is finalized need to release one more non-breaking version of SDK supporting that.


I would be working 3 days a week on this (based on my availability for the last 3 months).

Known Limitations

Although I aim at delivering all proposed features as outlined, there may be some higher priority tasks coming up that need to be worked on, thus not every proposed item is expected to be delivered.


SDK should satisfy the demands of projects depending on it. In the same, it should be easy to use, well-documented, well-typed, and built according to the modern standards of the JavaScript ecosystem.


The work outcome will be published at GitHub - aeternity/aepp-sdk-js: JavaScript SDK for the æternity blockchain and related repositories under ISC license.


Maintenance is part of the proposal and included in the proposed timeframe.

Final report

Overall spent 115.26 hours out of 300 hours available. Here is a list of issues closed in this grant, the same for merged pull requests. The most noticeable change is:

There were no releases made while working on this grant.

I started to work on these features, but was not able to deliver them in this grant because of third parties:

Because they contain breaking changes:

There is significant progress regarding some of the objectives defined at the beginning, but the others were postponed due to reported issues and to avoid making breaking changes.

Thank you for the update on your grant activities. The contributions, especially the integration for Basic Ceres compatibility and the support for all names delegation to contract are notable achievements that enhance the aepp-sdk-js’s functionality.

Please continue to keep us informed of any development :rocket: :rocket: :rocket:
