Blockscout App SDK

A React SDK for integrating Blockscout transaction notifications and transaction history into your dApp.

Features

• Transaction Toast Notifications
• Transaction History Popup
• Transaction interpretation and summaries
• Support for multiple chains
• Mobile-responsive design

Installation

npm install @blockscout/app-sdk
# or
yarn add @blockscout/app-sdk

Usage

1. Transaction Toast Notifications

The transaction toast feature provides real-time notifications for transaction status updates. It shows pending, success, and error states with detailed transaction information.

Setup

Wrap your application with the NotificationProvider:

import { NotificationProvider } from "@blockscout/app-sdk";

function App() {
  return (
    <NotificationProvider>
      <YourApp />
    </NotificationProvider>
  );
}

Using Transaction Toast

import { useNotification } from "@blockscout/app-sdk";

function YourComponent() {
  const { openTxToast } = useNotification();

  const handleTransaction = async (txHash) => {
    try {
      // Your transaction logic here
      await sendTransaction();

      // Show transaction toast
      openTxToast("1", txHash); // '1' is the chain ID for Ethereum mainnet
    } catch (error) {
      console.error("Transaction failed:", error);
    }
  };

  return (
    <button onClick={() => handleTransaction("0x123...")}>
      Send Transaction
    </button>
  );
}

2. Transaction History Popup

The transaction history popup allows users to view recent transactions for a specific address or all transactions on a chain.

Setup

Wrap your application with the TransactionPopupProvider:

import { TransactionPopupProvider } from "@blockscout/app-sdk";

function App() {
  return (
    <TransactionPopupProvider>
      <YourApp />
    </TransactionPopupProvider>
  );
}

Using Transaction Popup

import { useTransactionPopup } from "@blockscout/app-sdk";

function YourComponent() {
  const { openPopup } = useTransactionPopup();

  // Show transactions for a specific address
  const showAddressTransactions = () => {
    openPopup({
      chainId: "1", // Ethereum mainnet
      address: "0x123...", // Optional: specific address
    });
  };

  // Show all transactions for a chain
  const showAllTransactions = () => {
    openPopup({
      chainId: "1", // Ethereum mainnet
    });
  };

  return (
    <div>
      <button onClick={showAddressTransactions}>
        View Address Transactions
      </button>
      <button onClick={showAllTransactions}>View All Transactions</button>
    </div>
  );
}

Features

Transaction Toast

• Real-time status updates (pending, success, error)
• Transaction interpretation and summaries
• Links to block explorer
• Automatic status polling
• Error handling with revert reasons

Transaction Popup

• View recent transactions
• Filter by address
• Transaction status indicators

Chain Compatibility

The SDK is compatible with any blockchain that has a Blockscout explorer instance with API v2 support. These chains are listed in the Chainscout. To verify if your target chain is supported, visit our compatibility checker.

Here are some common supported chain IDs:

• 1: Ethereum Mainnet
• 137: Polygon Mainnet
• 42161: Arbitrum One
• 10: Optimism

API Reference

useNotification Hook

const { openTxToast } = useNotification();

// Open a transaction toast
openTxToast(chainId: string, hash: string): Promise<void>

useTransactionPopup Hook

const { openPopup } = useTransactionPopup();

// Open transaction popup
openPopup(options: {
  chainId: string;
  address?: string;
}): void
