🆕🐥 First Timers Only

This issue is reserved for people who have never contributed to Hedera or any open source project in general. We know that creating a pull request (PR) is a major barrier for new contributors. The goal of this issue and all other issues labeled by 'good first issue' is to help you make your first contribution to Hedera.

👾 Description of the issue

Problem

The Hedera Java SDK includes an example that demonstrates how to create an account with a threshold key (CreateAccountThresholdKeyExample.java). This is a crucial feature that allows users to create accounts where multiple signatures are required to authorize transactions, which is an essential security mechanism.

However, there is no equivalent example available in the Hedera JavaScript SDK. Developers using the JavaScript SDK would benefit from having a similar example to guide them in creating accounts with threshold keys in a JavaScript environment.

Solution

Below is a link to the existing Java implementation, which can serve as a basis for creating the JavaScript example: CreateAccountThresholdKeyExample.java

Steps to Implement

Generate key pairs using the JavaScript SDK (PrivateKey.generateED25519()).
Create a threshold key by initializing a KeyList with a threshold and adding the public keys.
Create an account with the threshold key.
Perform a transaction requiring multi-signature from the threshold key.
Delete the account as part of cleanup, also requiring multi-signature.

Expected Outcome

The new example will provide developers with a clear guide for setting up multi-signature accounts using threshold keys in JavaScript. This is especially important for those building more complex, secure applications that require multi-signature transactions

By providing this JavaScript example, we align the JavaScript SDK with the Java SDK in terms of documentation and usability, making it easier for developers to build Hedera-based applications.
