DigifferWallet

DigifferWallet is a JavaScript library designed to integrate Google OAuth login for creating and managing blockchain wallets. It provides a simple interface to show a login popup, handle Google login responses, and perform various wallet-related operations such as creating wallets, getting balances, and interacting with smart contracts.

Installation

Install the package using npm or yarn:

Using NPM

npm install digiffer-wallet-web

Using Yarn

yarn add digiffer-wallet-web

Then, include the DigifferWallet class in your project.

Usage

Initialization

Initialize the DigifferWallet class with the necessary configuration:

import DigifferWallet from './path/to/DigifferWallet';

const config = {
    hostUrl: 'https://your-api-host.com',
    apiKey: 'your-api-key',
    googleClientID: 'your-google-client-id'
};

const digifferWallet = new DigifferWallet(config);

Handle Login

To display the login popup, call the initLogin method with a response handler function:

  const handleLogin = async () => {
    try {
        digifferWallet.initLogin((response) => {
          console.log('Google login response:', response);
        });
    } catch (error) {
        console.error('Error in Login', error);
    }
  };

  <button onClick={handleLogin}>Login </button>

API Methods

DigifferWallet provides several methods for interacting with the wallet:

getWalletAddress(requestData)

Get the wallet address for the given user.

const requestData = { "sub_id": "user-sub-id" };
const walletData = await digifferWallet.getWalletAddress(requestData);
console.log(walletData);

getBalance(requestData)

Get the balance of the wallet.

const requestData = { "sub_id" : "user-sub-id" } // for Native token balance
const requestData = { "sub_id" : "user-sub-id", "token": "0xe954c2d9ff2a4d260dcd32386b1f9fc8135d2522" } // Custom token balance

const balance = await digifferWallet.getBalance(requestData);
console.log(balance);

readContract(requestData)

Read data from a smart contract.

const requestData= { "sub_id": "user-sub-id", "contractAddress": "Contract Address Here", "contractABI": [], "functionName": "contract-function-name", "functionArguments": "Function aruguments (Leave Blank if empty) " }
const contractData = await digifferWallet.readContract(requestData);
console.log(contractData);

writeContract(requestData)

Write data to a smart contract.

const requestData = { "sub_id": "user-sub-id", "contractAddress": "Contract Address Here", "contractABI": [], "functionName": "contract-function-name", "functionArguments": [] }
const writeResponse = await digifferWallet.writeContract(requestData);
console.log(writeResponse);

writeMultipleOnContract(requestData)

Perform multiple transactions on a smart contract.

const requestData = { "sub_id": "user-sub-id", "transactionData": [
    {
      "contractAddress": "Contract Address Here", "contractABI": [], "functionName": "contract-function-name", "functionArguments": [] 
    }
    {
      "contractAddress": "Contract Address Here", "contractABI": [], "functionName": "contract-function-name", "functionArguments": [] 
    }
]}
const batchResponse = await digifferWallet.writeMultipleOnContract(requestData);
console.log(batchResponse);
