JustaName Core SDK

The JustaName Core SDK empowers developers to seamlessly integrate robust digital identity and subnaming features into their Web3 applications. It simplifies the complexities of blockchain addresses by enabling the use of human-readable subdomains within the Ethereum Name Service (ENS).

Key Features

• User-Friendly Addresses: Replace unwieldy blockchain addresses with memorable subnames (e.g., 'yourname.eth').
• Secure Sign-In (SIWE): Implement Ethereum-based authentication without centralized systems.
• Subname Management: Create, reserve, update, and revoke subdomains with ease.
• Cross-Chain Compatibility: Support interactions across various blockchain networks.

Installation

npm install @justaname.id/sdk

Configuration

Obtain an API Key and initialize the SDK:

import { JustaName } from '@justaname.id/sdk';

async function main() {
  const apiKey = 'your-api-key';
  const justaName = JustaName.init({ apiKey });
  // Your SDK is now ready to be used!
}

main();

Usage Examples

SIWE: Request a Secure Sign-In Challenge

const requestChallengeResponse = await justaName.siwe.requestChallenge({
  chainId: 1,
  origin: 'http://localhost:3333',
  address: '0x59c44836630760F97b74b569B379ca94c37B93ca',
  domain: 'localhost',
});

Subnames: Add a New Subname

const addedUser = await justaName.subnames.addSubname({
  username: 'testuser',
  ensDomain: 'justaname.id',
  chainId: 1,
}, {
  xAddress: '0x59c44836630760F97b74b569B379ca94c37B93ca',
  xSignature: '...',
  xMessage: '...'
});

Error Handling

try {
  // SDK operations
} catch (error) {
  console.error("Error:", error.message);
}
