IAM Libraries

Identity Access and Management (IAM) Client Library

A TypeScript library that provides high-level functions related to the identity and access management (IAM) for all users, assets, organizations and applications that are anchored on the Energy Web Chain. This includes:

• Management of Switchboard namespaces

• DID/DID Document management

• Creation and governance of organizations, applications and their associated roles. Once created, these are persisted on the IAM Cache Server

• Claim requests, verification and issuance for role permissioning. Once created, claims are persisted on the IAM Cache Server

• Staking functionality

DID Library

A class-based TypeScript library that provides an abstraction layer to manage and interact with DIDs and Verifiable Credentials on the Energy Web Chain.

The DID Library enables users to adopt and/or implement different DID methods, which promotes interoperability with other methods of decentralized identifiers. The DID library currently implements the ERC1056 standard for creating and updating identities on the blockchain.

The DID library interacts with the Energy Web Chain using the ethers.js library.

Passport-DID-Auth

A backend class-based TypeScript library that allows other JavaScript/TypeScript applications to easily add authentication and authorization based on Switchboard roles to their applications. This allows any application to use Switchboard's decentralized approach to identity and access management.
