1. Installation​

To get started with FuseBox Web SDK, install it using npm:

npm install @fuseio/fusebox-web-sdk

2. Getting Started​

Importing FuseBox Web SDK​

import { FuseSDK } from "@fuseio/fusebox-web-sdk";

Initializing a Smart Contract Wallet​

const fuse = await FuseSDK.init(publicApiKey, credentials, {
    withPaymaster: true,
});

Replace 'YOUR_API_KEY' with your actual API key obtained from the Fuse Console Dashboard. If you don’t want to enable Paymaster set it to false. It is default false

Authentication​

const userToken = await fuse.authenticate('USER_PRIVATE_KEY');

The authenticate method returns a JSON Web Token (JWT) that will be used for making calls to other methods in the SDK.

3. Available Methods​

authenticate​

Authenticate a user using their private key and obtain a user token (JWT) for subsequent operations.

const userToken = await fuse.authenticate('USER_PRIVATE_KEY');

init​

Initialize the FuseBox Smart Contract Wallet with your API key.

fuse.init({ apiKey: 'YOUR_API_KEY' });

callContract​

Call a method on a smart contract deployed on the Fuse Network.

  const to = <RECEIVER_ADDRESS>;
  const value = parseEther("0.001");
  const data = Uint8Array.from([]);

  const res = await fuse.callContract(to, value, data);
  
  console.log(`UserOpHash: ${res?.userOpHash}`);
  console.log('Waiting for transaction...');
  const receipt = await res?.wait();
  console.log('Transaction Hash:', receipt?.transactionHash);

executeBatch​

Execute a batch of transactions atomically.

const batchTransactions = [
  { method: 'transfer', parameters: ['RECIPIENT_ADDRESS', 'AMOUNT'] },
  // Add more transactions as needed
];
await fuse.executeBatch(batchTransactions, wallet);

getBalance​

Retrieve the balance of a wallet.

const balance = await fuse.getBalance(wallet);

getAllowance​

Retrieve the allowance of a wallet.

const allowance = await fuse.getAllowance('TOKEN_ADDRESS', 'SPENDER');

getERC20TokenDetails​

Retrieve details about an ERC-20 token.

const tokenDetails = await fuse.getERC20TokenDetails('TOKEN_ADDRESS');

4. Example Usage​

Creating a Smart Contract Wallet​

// createSmartAccountWallet.mjs

// Import necessary libraries
import { ethers } from 'ethers';
import { FuseSDK } from '@fuseio/fuse-web-sdk';

// Main function to create a Smart Account Wallet
const main = async () => {
  // Load your private key from the environment variables
  const credentials = new ethers.Wallet(process.env.PRIVATE_KEY as string);

  // Retrieve your public API key from the environment variables
  const publicApiKey = process.env.PUBLIC_API_KEY as string;

  // Initialize the Fuse SDK with your public API key and wallet credentials
  const fuseSDK = await FuseSDK.init(publicApiKey, credentials);

  // Log the sender address of the Smart Wallet
  console.log(`Sender Address is ${fuseSDK.wallet.getSender()}`);
};

// Execute the main function
main();

Executing Batch Transactions - Coming Soon!

const batchTransactions = [
  { method: 'transfer', parameters: ['RECIPIENT_ADDRESS', 'AMOUNT'] },
  // Add more transactions as needed
];
await fuse.executeBatch(batchTransactions, wallet);

Executing Batch Transactions​

const batchTransactions = [
  { method: 'transfer', parameters: ['RECIPIENT_ADDRESS', 'AMOUNT'] },
  // Add more transactions as needed
];
await fuse.executeBatch(batchTransactions, wallet);

5. Additional Information​

Authentication Token (JWT)​

The authenticate method returns a JSON Web Token (JWT) that must be used as the sender parameter in subsequent method calls.
