@cheqd/sdk v4.0.5

TypeScript SDK for cheqd

ℹ️ Overview

The purpose of this @cheqd/sdk NPM package is to provide base functionality for interacting with cheqd network. It combines the DID and DID-Linked Resources modules, and putting them into a Cosmos transaction wrapper using CosmJS.

This package is consumed by other SDKs/libraries such as Veramo SDK for cheqd and Hyperledger Aries Framework JavaScript (AFJ) to add cheqd network support.

This package includes:

• TypeScript Protobuf definitions for custom cheqd Cosmos SDK modules
• CosmJS, for base Cosmos SDK module functions

🆔 Features

Our identity documentation site provides tutorials for utilising the identity features on cheqd network.

With this SDK, developers are able to:

• ✅ Create a did:cheqd method DID
• ✅ Update a did:cheqd method DID
• ✅ Deactivate a did:cheqd method DID
• ✅ Create or update a DID-Linked Resource

🧰 Tooling

• ✅ Raw payload creator: Enables users to generate a valid raw DID payload which is ready to be populated, depending on the use case. For example, did-provider-cheqd leverages this helper in the CLI application.
• ✅ Identity key converter: Enables users to convert specific key formats from different kinds of SDKs, by transforming the input keys into valid sign inputs for a cheqd specific DID transaction (e.g. createDidDocTx, updateDidDocTx). For example, the Veramo SDK for cheqd uses this helper to enable users to pass a key in a Veramo SDK specific format to a cheqd sign input keys interface.
