DID-ETH Resolver CLI

Overview

The DID-ETH Resolver CLI is a command-line interface tool for resolving Decentralized Identifiers (DIDs) on the Ethereum (ETH) blockchain. It allows users to query and verify digital identities anchored in the Ethereum blockchain.

Prerequisites

• Ethereum Node or RPC Endpoint Access
• XMTP didethresolver Endpoint Access
• Rust
  • clap
  • dotenv

Installation

For Node.js:

npm install did-eth-resolver-cli

For Python:

pip install did-eth-resolver-cli

Configuration

Set up your Ethereum node or specify an RPC endpoint in the configuration file:

{
    "RpcUrl": "http://localhost:8545"
}

Optionally, dotenv may be used for configuration, or a command line argument such as "--rpcurl". Preferrably multiple of these paths are possible.

Usage

To resolve a DID:

did-eth-resolver resolve [DID]

Example:

did-eth-resolver resolve did:eth:123456789abcdef

Output:

{
  "@context": [
    "https://www.w3.org/ns/did/v1",
    "https://w3id.org/security/suites/ed25519-2020/v1"
  ],
  "controller": "did:ethr:123456789abcdef",
  "id": "did:ethr:123456789abcdef",
  "service": [
    {
      "id": "did:ethr:123456789abcdef",
      "recipientKeys": "123456789abcdef",
      "serviceEndpoint": "XMTP",
      "type": "MessagingService"
    }
  ],
  "verificationMethod": [
    {
      "controller": "did:ethr:123456789abcdef",
      "id": "did:ethr:123456789abcdef",
      "publicKeyMultibase": "123456789abcdef",
      "type": "Ed25519VerificationKey2020"
    }
  ]
}

Commands

• resolve: Resolves a DID on the Ethereum Classic blockchain and returns the DID document.
• help: Displays help information about the commands.

DID Document Format

The resolved DID document follows the standard DID document format including properties like @context, id, publicKey, authentication, etc.

Error Handling

Errors such as invalid DIDs, network issues, or unsupported features are handled gracefully with descriptive messages.

Security Considerations

• Ensure secure and private access to the Ethereum Classic node.
• Regularly update the CLI tool to get security updates and patches.

This is a basic outline, and the actual documentation would need to include more specific details and instructions tailored to the actual functionality and requirements of the DID-ETH Resolver CLI.
