@particle-network/connectkit @particle-network/aa Demo Application

Particle Connect, Account Abstraction SDK, Next.js, & ethers V6 on the 5ire Chain

⚡️ Basic demo application using @particle-network/connectkit and @particle-network/aa to initiate social login and send transactions via an account abstraction smart account on the 5ire Chain.

Note that Account Abstraction is included wihint the new connectkit package. @particle-network/aa is required when using an EIP 1193 provider like ehter.js. This demo showcases both options.

This app allows you to log in using social logins and interact with various testnets by displaying account information and sending a gasless transfer transaction to an address you can input in the UI.

Built using create @particle-network/connectkit

npm init @particle-network/connectkit@latest
# or
pnpm create @particle-network/connectkit@latest
# or
yarn create @particle-network/connectkit

🔑 Particle Connect

Particle Connect enables a unified modal driving connection with social logins (through Particle Auth) and standard Web3 wallets, creating an equally accessible experience for Web3 natives and traditional consumers. Particle Connect is an all-in-one SDK capable of handling end-to-end onboarding and wallet connection.

This app enables you to log in using social logins or Web3 methods via Particle Connect and interact with the Ethereum Sepolia, Base Sepolia, and Avalanche Fuji testnets. You can view your account information and send transfer transactions to any address you input in the UI.

🪪 Account Abstraction SDK

Particle Network natively supports and facilitates the end-to-end utilization of ERC-4337 account abstraction. This is primarily done through the account abstraction SDK, which can construct, sponsor, and send UserOperations, deploy smart accounts, retrieve fee quotes, and perform other key functions.

Every gasless transaction is automatically sponsored on testnet. On mainnet, you'll need to deposit USDT in the Paymaster.

Sending AA Transactions

You can send gasless transactions using the native smartAccount instance provided by Particle Connect.

This does not require the Particle AA ADK.

Here’s an example from the demo:

import { useSmartAccount } from "@particle-network/connectkit";
const smartAccount = useSmartAccount();

/**
 * Sends a transaction using the native AA Particle provider with gasless mode.
 */
const executeTxNative = async () => {
  setIsSending(true);
  try {
    const tx = {
      to: recipientAddress,
      value: parseEther("0.01").toString(),
      data: "0x",
    };

    // Fetch fee quotes and use verifyingPaymasterGasless for a gasless transaction
    const feeQuotesResult = await smartAccount?.getFeeQuotes(tx);
    const { userOp, userOpHash } =
      feeQuotesResult?.verifyingPaymasterGasless || {};

    if (userOp && userOpHash) {
      const txHash =
        (await smartAccount?.sendUserOperation({
          userOp,
          userOpHash,
        })) || null;

      setTransactionHash(txHash);
      console.log("Transaction sent:", txHash);
    } else {
      console.error("User operation is undefined");
    }
  } catch (error) {
    console.error("Failed to send transaction:", error);
  } finally {
    setIsSending(false);
  }
};

For users utilizing an EIP1193 provider such as ethers.js, you'll need to leverage the Particle AA SDK. Install it with the following command:

yarn add @particle-network/aa

Here’s how to use it with ethers.js:

// Initialize custom provider with gasless transaction mode
const customProvider = smartAccount
  ? new ethers.BrowserProvider(
      new AAWrapProvider(
        smartAccount,
        SendTransactionMode.Gasless
      ) as Eip1193Provider,
      "any"
    )
  : null;

/**
 * Sends a transaction using the ethers.js library.
 * This transaction is gasless since the customProvider is initialized as gasless.
 */
const executeTxEthers = async () => {
  if (!customProvider) return;

  const signer = await customProvider.getSigner();
  setIsSending(true);
  try {
    const tx = {
      to: recipientAddress,
      value: parseEther("0.01").toString(),
    };

    const txResponse = await signer.sendTransaction(tx);
    const txReceipt = await txResponse.wait();

    setTransactionHash(txReceipt?.hash || null);
  } catch (error) {
    console.error("Failed to send transaction using ethers.js:", error);
  } finally {
    setIsSending(false);
  }
};
