Overview of the EVM Blockbook JSON-RPC Add-on​

The EVM Blockbook JSON-RPC Add-On gives you access to balances, transactions, and address balance history for addresses via JSON-RPC. This add-on utilizes the Blockbook REST API, which is designed to offer efficient querying of blockchain data, including detailed analyses of smart contracts, native ETH transfers, internal transactions, and token transfers.

Benefits Over Standard EVM Methods​

  • Detailed Data: The Blockbook JSON-RPC Add-on returns more detailed data compared to standard EVM methods, including internal transactions and token transfers.
  • Efficient Querying: It simplifies executing efficient queries on transactions and balances, reducing the complexity of interacting with the blockchain.
  • Currency Conversion: Allows retrieving the currency rate for a specific currency (e.g., USD, EUR) and date for the specific timestamp, making it easier to perform financial analysis and reporting.

As of this writing, the EVM Blockbook add-on provides 8 RPC methods. We will use one of them in this guide:

  • bb_getAddress: Returns balances and transactions of an address. The returned transactions are sorted by block height, newest blocks first.

Setting Up an Ethereum Endpoint​

Before you begin, please note that the EVM Blockbook JSON-RPC is a paid add-on. Please check the details here and compare plans based on your needs.

Setting up your Ethereum endpoint with the EVM Blockbook JSON-RPC is quite easy. If you haven't signed up already, you can create an account here.

Once you have logged in, navigate to the Endpoints page and click Create an endpoint. Select Ethereum mainnet, then click Next. Then, you'll be prompted to configure the add-on. Activate EVM Blockbook JSON-RPC. Afterward, simply click Create Endpoint.

If you already have a Ethereum endpoint without the add-on, go to the Add-ons page within your Ethereum endpoint, select the EVM Blockbook JSON-RPC, and activate it.

Quicknode Endpoints page

Once your endpoint is ready, copy the HTTP Provider link and keep it handy, as you'll need it in the next section.

Building an Ethereum Transaction Report Generator with EVM Blockbook JSON-RPC​

Before you start, make sure Node.js is installed on your machine. Node.js will be the backbone for running your application, and npm, the default package manager included with Node.js, will handle all dependencies efficiently. You can find installation instructions on their official page.

Additionally, if you haven't already installed TypeScript, set it up globally to make it available across all your projects by running the following commands:

npm install -g typescript ts-node

Setting Up the Project​

Before we start coding, let's take a look at what we will build. In the end, our app will resemble the one shown below.

App Overview

Step 1: Initialize a New Vite Project​

Create a directory for your project and initialize a new Vite project within it:

npm create vite@latest ethereum-transaction-reports -- --template react-ts
cd ethereum-transaction-reports

This command will create a new directory named ethereum-transaction-reports with the Vite project template for React and TypeScript, then change your current directory to the new project folder.

Step 2: Install Necessary Packages​

Proceed to install the necessary packages:

npm install axios luxon dotenv fs-extra @quicknode/sdk
npm i --save-dev @types/fs-extra @types/luxon tailwindcss postcss autoprefixer
📘 Packages
  • axios: A promise-based HTTP client for making requests to external services, ideal for fetching data from APIs.
  • luxon: A powerful, modern library for working with dates and times in JavaScript. Luxon is used to handle and manipulate dates and times, which is crucial for processing transaction timestamps effectively.
  • dotenv: A zero-dependency module that loads environment variables from a .env file into process.env, ensuring sensitive information is kept secure.
  • fs-extra: A module for interacting with the file system, such as writing files and reading files.
  • @quicknode/sdk: The QuickNode SDK provides convenient access to QuickNode's infrastructure, facilitating easier interaction with the Ethereum blockchain. This SDK enhances the application's capability to connect, query, and interact with Ethereum, streamlining complex blockchain operations.
  • @types/fs-extra and @types/luxon: These are DefinitelyTyped packages that provide TypeScript type definitions for fs-extra and luxon.
  • tailwindcss: A utility-first CSS framework that provides a set of predefined classes to help build custom designs without writing custom CSS. Tailwind CSS promotes a design system based approach and speeds up the styling process.
  • postcss: A tool for transforming CSS with JavaScript plugins. PostCSS allows you to use plugins to automate routine CSS tasks, such as optimizing styles or integrating with CSS preprocessors and frameworks.
  • autoprefixer: A PostCSS plugin that parses your CSS and adds vendor prefixes to CSS rules. It helps ensure compatibility with different browsers by automatically applying the necessary prefixes.

Step 3: Set Up Tailwind CSS​

Now, set up Tailwind CSS in the project by running the command:

npx tailwindcss init -p

Modify the tailwind.config.js file to add the paths in the configuration file:

/** @type {import('tailwindcss').Config} */
export default {
  content: ['./index.html', './src/**/*.{js,ts,jsx,tsx}'],
  theme: {
    extend: {},
  },
  plugins: [],
}

Delete all code in the ./src/index.css file and add the @tailwind directives in it.

@tailwind base;
@tailwind components;
@tailwind utilities;

After these commands, the required packages are installed, and Tailwind configuration files are completed.

Building the Project​

Before diving into the coding of our Ethereum transaction reports tool, it's crucial to understand its operational flow. This overview ensures that our development is guided by a clear understanding of how each component contributes towards achieving our goal. Here is a breakdown of the operational flow:

  • Import Dependencies: Each component and helper file begins by importing necessary libraries and modules. For instance, App.tsx might import React, ReportForm.tsx, and ResultTable.tsx to assemble the user interface, while helper functions from blockbookMethods.ts and calculateVariables.ts manage data retrieval and processing.

  • User Input: The user interacts with the ReportForm.tsx component, inputting an Ethereum address and selecting a date range for the transaction report. This data is then submitted to the main application logic in App.tsx.

  • Fetch Transaction Data: Upon form submission, App.tsx calls the function bb_getAddress from blockbookMethods.ts, using the provided Ethereum address to gather its transaction history from Blockbook, including details of ERC-20, ERC-721, and ERC-1155 token transfers.

  • Process Data: After data retrieval, the calculateVariables function from calculateVariables.ts processes this data. This function handles different aspects like token transfers, smart contract interactions, and standard Ethereum transactions to provide a structured dataset.

  • Display Results: Once the data is processed, the data is passed to ResultTable.tsx, which renders the data in a user-friendly table format on the front end, allowing users to view and analyze their Ethereum transaction history.

  • Generate Report: If a user wants to copy or export the data in a CSV format, the convertToCsv function organizes the processed data into a CSV format, making it suitable for analysis and reporting.

Now, let's start coding.

Step 1: Creating Necessary Files​

Create the necessary files in your project's directory (i.e., ethereum-transaction-reports):

mkdir src/helpers
mkdir src/components

echo > .env
echo > src/interfaces.ts
echo > src/helpers/blockbookMethods.ts
echo > src/helpers/calculateVariables.ts
echo > src/helpers/convertToCsv.ts
echo > src/components/CopyIcon.tsx
echo > src/components/ReportForm.tsx
echo > src/components/ResultTable.tsx

📘 Files

  • .env: Stores environment variables such as your QuickNode endpoint URL. This setup ensures sensitive information like API keys is securely managed and easily configurable.

  • src/interfaces.ts: Defines TypeScript interfaces to ensure type safety and consistency across the application. This file includes type definitions for the data structures used in and returned by various functions, enhancing code reliability and maintainability.

  • src/helpers/blockbookMethods.ts: Contains functions to interface with the Ethereum Blockbook API, fetching transaction and smart contract interaction data for specified Ethereum addresses.

  • src/helpers/calculateVariables.ts: Processes the Ethereum blockchain data retrieved by blockbookMethods.ts, including calculations for transactions, token transfers, and interactions with contracts.

  • src/helpers/convertToCsv.ts: Converts the processed blockchain data into a CSV format, making it suitable for analysis and distribution.

  • src/components/CopyIcon.tsx: A React component that provides a user interface element for copying text to the clipboard.

  • src/components/ReportForm.tsx: A React component that renders a form for users to input parameters such as Ethereum addresses and date ranges. This form is used to generate specific transaction reports based on user input.

  • src/components/ResultTable.tsx: A React component that displays the transaction report data in a tabular format, making it easy for users to read and analyze the information.

Step 2: Configuring Environment Variables​

Store your QuickNode endpoint and other sensitive information, if you have them, in a .env file.

Open the .env file and modify it as follows. Do not forget to replace the YOUR_QUICKNODE_ETHEREUM_ENDPOINT_URL placeholder with your QuickNode Ethereum HTTP provider URL.

.env
VITE_QUICKNODE_ENDPOINT = "YOUR_QUICKNODE_ETHEREUM_ENDPOINT_URL"

Step 3: Creating Interfaces​

The interfaces.ts file defines TypeScript interfaces to ensure type safety and consistency across the application. This file includes type definitions for the data structures used in and returned by various functions, enhancing code reliability and maintainability.

Open the src/interfaces.ts file with your code editor and modify the file as follows:

src/interfaces.ts
import { DateTime } from "luxon";

export interface CalculateVariablesOptions {
  startDate?: DateTime;
  endDate?: DateTime;
  userTimezone?: string;
}

export interface Config {
  startDate?: {
    year: number;
    month: number;
    day: number;
  };
  endDate?: {
    year: number;
    month: number;
    day: number;
  };
  userTimezone?: string;
}

export interface Result {
  page: number;
  totalPages: number;
  itemsOnPage: number;
  address: string;
  balance: string;
  unconfirmedBalance: string;
  unconfirmedTxs: number;
  txs: number;
  nonTokenTxs: number;
  internalTxs: number;
  transactions: Transaction[];
  nonce: string;
}

export interface Transaction {
  txid: string;
  version: number;
  vin: Vin[];
  vout: Vout[];
  ethereumSpecific?: EthereumSpecific;
  tokenTransfers?: TokenTransfer[];
  blockHash: string;
  blockHeight: number;
  confirmations: number;
  blockTime: number;
  size: number;
  vsize: number;
  value: string;
  valueIn: string;
  fees: string;
  hex?: string;
}

export interface EthereumSpecific {
  internalTransfers?: InternalTransfer[];
  parsedData?: ParsedData;
}

export interface InternalTransfer {
  from: string;
  to: string;
  value: string;
}

export interface ParsedData {
  methodId: string;
  name: string;
}

export interface TokenTransfer {
  type: string;
  from: string;
  to: string;
  contract: string;
  name: string;
  symbol: string;
  decimals: number;
  value: string;
  multiTokenValues?: MultiTokenValues[];
}

export interface MultiTokenValues {
  id: string;
  value: string;
}

export interface ExtractedTransaction {
  txid: string;
  blockHeight: number;
  direction: "Incoming" | "Outgoing";
  txType: string;
  assetType: string;
  senderAddress: string;
  receiverAddress: string;
  value: string;
  fee: string;
  day: string;
  timestamp: string;
  userTimezone: string;
  status: string;
  methodNameOrId: string;
  contract?: string;
  tokenId?: string;
}

export interface ExtendedResult extends Result {
  extractedTransaction: ExtractedTransaction[];
  startDate: DateTime;
  endDate: DateTime;
}

export interface Vin {
  txid: string;
  vout?: number;
  sequence: number;
  n: number;
  addresses: string[];
  isAddress: boolean;
  value: string;
  hex: string;
  isOwn?: boolean;
}

export interface Vout {
  value: string;
  n: number;
  hex: string;
  addresses: string[];
  isAddress: boolean;
  spent?: boolean;
  isOwn?: boolean;
}

Step 4: Fetching Data with Blockbook​

The blockbookMethods.ts file includes functions designed to interact with a QuickNode endpoint using the Blockbook API. These functions facilitate fetching detailed transaction data for a specific Ethereum address and obtaining token transfer details.

Open the src/helpers/blockbookMethods.ts file with your code editor and modify the file as follows:

src/helpers/blockbookMethods.ts
// Import necessary types and libraries
import { Result } from "../interfaces";
import axios from "axios";

// Retrieve the QuickNode endpoint URL from environment variables
const QUICKNODE_ENDPOINT = import.meta.env.VITE_QUICKNODE_ENDPOINT as string;

// Fetches detailed transaction data for a specified Ethereum address
export async function bb_getAddress(address: string): Promise<Result> {
  try {
    // Prepare the request payload for the bb_getAddress method
    const postData = {
      method: "bb_getAddress",
      params: [
        address,
        { page: "1", size: "1000", fromHeight: "0", details: "txs" }, // Query parameters
      ],
      id: 1,
      jsonrpc: "2.0",
    };

    // Make the POST request to the QuickNode endpoint
    const response = await axios.post(QUICKNODE_ENDPOINT, postData, {
      headers: { "Content-Type": "application/json" },
      maxBodyLength: Infinity,
    });

    // Check for a successful response and return the data
    if (response.status === 200 && response.data) {
      return response.data.result;
    } else {
      throw new Error("Failed to fetch transactions");
    }
  } catch (error) {
    console.error(error);
    throw error;
  }
}

Step 5: Processing Data​

The calculateVariables.ts file processes the Ethereum blockchain data retrieved by blockbookMethods.ts. This file handles calculations for transactions, token transfers, and interactions with contracts.

Open the src/helpers/calculateVariables.ts file with your code editor and modify the file as follows:

src/helpers/calculateVariables.ts
// Import necessary types and libraries
import { DateTime } from "luxon";
import { viem } from "@quicknode/sdk";
import {
  Result,
  ExtractedTransaction,
  ExtendedResult,
  CalculateVariablesOptions,
} from "../interfaces";

export async function calculateVariables(
  result: Result,
  options: CalculateVariablesOptions = {}
): Promise<ExtendedResult> {
  const userTimezone = options.userTimezone || DateTime.local().zoneName;
  const startDate = options.startDate || DateTime.now().setZone(userTimezone);
  const endDate = options.endDate || DateTime.now().setZone(userTimezone);

  const startOfPeriod = startDate.startOf("day");
  const endOfPeriod = endDate.endOf("day");

  const extractedData: ExtractedTransaction[] = [];

  for (const transaction of result.transactions) {
    const blockTime = DateTime.fromMillis(transaction.blockTime * 1000, {
      zone: userTimezone,
    });
    const day = blockTime.toFormat("yyyy-MM-dd");
    const timestamp: string = blockTime.toString() || "";

    const status = transaction.confirmations > 0 ? "Confirmed" : "Pending";

    let methodNameOrId = "";
    if (transaction.ethereumSpecific?.parsedData) {
      const { name, methodId } = transaction.ethereumSpecific.parsedData;
      if (name && methodId) {
        methodNameOrId = `${name} (${methodId})`;
      } else {
        methodNameOrId = name || methodId || "Unknown";
      }
    }

    if (blockTime < startOfPeriod || blockTime > endOfPeriod) continue;

    // Handle normal ETH transactions
    for (const vin of transaction.vin) {
      if (vin.addresses && vin.addresses.includes(result.address)) {
        for (const vout of transaction.vout) {
          if (vout.value === "0") continue;
          extractedData.push({
            txid: transaction.txid,
            blockHeight: transaction.blockHeight,
            direction: "Outgoing",
            txType: "Normal",
            assetType: "ETH",
            senderAddress: result.address,
            receiverAddress: vout.addresses.join(", "),
            value: viem.formatEther(BigInt(vout.value)),
            fee: viem.formatEther(BigInt(transaction.fees)),
            day,
            timestamp,
            userTimezone,
            status,
            methodNameOrId,
          });
        }
      }
    }

    for (const vout of transaction.vout) {
      if (vout.addresses && vout.addresses.includes(result.address)) {
        extractedData.push({
          txid: transaction.txid,
          blockHeight: transaction.blockHeight,
          direction: "Incoming",
          txType: "Normal",
          assetType: "ETH",
          senderAddress: transaction.vin.map((vin) => vin.addresses).join(", "),
          receiverAddress: result.address,
          value: viem.formatEther(BigInt(vout.value)),
          fee: viem.formatEther(BigInt(transaction.fees)),
          day,
          timestamp,
          userTimezone,
          status,
          methodNameOrId,
        });
      }
    }

    // Handle internal ETH transfers
    if (transaction.ethereumSpecific?.internalTransfers) {
      for (const transfer of transaction.ethereumSpecific.internalTransfers) {
        if (
          transfer.from === result.address ||
          transfer.to === result.address
        ) {
          const direction =
            transfer.from === result.address ? "Outgoing" : "Incoming";

          extractedData.push({
            txid: transaction.txid,
            blockHeight: transaction.blockHeight,
            direction: direction as "Outgoing" | "Incoming",
            txType: "Internal",
            assetType: "ETH",
            senderAddress: transfer.from,
            receiverAddress: transfer.to,
            value: viem.formatEther(BigInt(transfer.value)),
            fee: viem.formatEther(BigInt(transaction.fees)),
            day,
            timestamp,
            userTimezone,
            status,
            methodNameOrId,
          });
        }
      }
    }

    // Handle token transfers
    if (transaction.tokenTransfers) {
      for (const tokenTransfer of transaction.tokenTransfers) {
        if (
          tokenTransfer.from === result.address ||
          tokenTransfer.to === result.address
        ) {
          const direction =
            tokenTransfer.from === result.address ? "Outgoing" : "Incoming";

          const assetType =
            tokenTransfer.name && tokenTransfer.symbol
              ? `${tokenTransfer.name} (${tokenTransfer.symbol})`
              : "N/A";

          let value = "";
          let tokenId = "";

          switch (tokenTransfer.type) {
            case "ERC1155":
              if (tokenTransfer.multiTokenValues) {
                const tokens = tokenTransfer.multiTokenValues;
                tokens.forEach((token, index) => {
                  tokenId += token.id + (index < tokens.length - 1 ? ", " : "");
                  value +=
                    token.value + (index < tokens.length - 1 ? ", " : "");
                });
              } else {
                // Handle the case where there are no multiTokenValues
                tokenId = "N/A";
                value = "N/A";
              }
              break;
            case "ERC721":
              value = "1";
              tokenId = tokenTransfer.value;
              break;
            case "ERC20":
              // Standard handling for ERC20 tokens using their decimal value
              value = viem.formatUnits(
                BigInt(tokenTransfer.value),
                tokenTransfer.decimals
              );
              tokenId = "N/A";
              break;
            default:
              continue;
          }

          extractedData.push({
            txid: transaction.txid,
            blockHeight: transaction.blockHeight,
            direction: direction as "Outgoing" | "Incoming",
            txType: tokenTransfer.type,
            assetType: assetType,
            senderAddress: tokenTransfer.from,
            receiverAddress: tokenTransfer.to,
            value: value,
            fee: viem.formatEther(BigInt(transaction.fees)),
            day,
            timestamp,
            userTimezone,
            status,
            methodNameOrId,
            contract: tokenTransfer.contract,
            tokenId: tokenId,
          });
        }
      }
    }
  }

  const extendedResult: ExtendedResult = {
    ...result,
    extractedTransaction: extractedData,
    startDate: startOfPeriod,
    endDate: endOfPeriod,
  };

  return extendedResult;
}

Step 6: Converting Data to CSV​

The convertToCsv.ts file converts the processed blockchain data into a CSV format, making it suitable for analysis and distribution.

Open the src/helpers/convertToCsv.ts file with your code editor and modify the file as follows:

src/helpers/convertToCsv.ts
import { ExtractedTransaction } from "../interfaces.ts";

const convertToCSV = (data: ExtractedTransaction[]) => {
  const csvRows = [];
  // Headers
  csvRows.push(
    [
      "Day",
      "Time",
      "Block",
      "Transaction ID",
      "Transaction Status",
      "Transaction Type",
      "Asset",
      "Sender Address",
      "Direction",
      "Receiver Address",
      "Amount",
      "Token ID",
      "Fees [ETH]",
      "Method Name/ID",
    ].join(",")
  );

  // Rows
  data.forEach((tx) => {
    const row = []; // Create an empty array for this row
    row.push(tx.day);
    row.push(
      new Date(tx.timestamp).toLocaleTimeString("en-US", {
        timeZone: tx.userTimezone,
        timeZoneName: "short",
      })
    );
    row.push(tx.blockHeight);
    row.push(tx.txid);
    row.push(tx.status);
    row.push(tx.txType);
    row.push(tx.assetType);
    row.push(tx.senderAddress);
    row.push(tx.direction);
    row.push(tx.receiverAddress);
    row.push(tx.value);
    row.push(tx.tokenId ? tx.tokenId : "N/A");
    row.push(tx.fee);
    row.push(
      tx.methodNameOrId.startsWith("0x")
        ? `"${tx.methodNameOrId}"`
        : tx.methodNameOrId
    );
    csvRows.push(row.join(",")); // Join each row's columns and push
  });

  return csvRows.join("\n"); // Join all rows
};

export const copyAsCSV = (data: ExtractedTransaction[]) => {
  const csvData = convertToCSV(data);
  navigator.clipboard.writeText(csvData).then(
    () => console.log("CSV copied to clipboard"),
    (err) => console.error("Failed to copy CSV: ", err)
  );
};

export const exportAsCSV = (
  data: ExtractedTransaction[],
  filename = "ethereum-report.csv"
) => {
  const csvData = convertToCSV(data);
  const blob = new Blob([csvData], { type: "text/csv;charset=utf-8;" });

  // Create a link to download the blob
  const link = document.createElement("a");
  link.href = URL.createObjectURL(blob);
  link.download = filename;
  link.style.visibility = "hidden";

  // Append to the document and trigger the download
  document.body.appendChild(link);
  link.click();

  // Clean up
  document.body.removeChild(link);
};

Step 7: Creating the Copy Icon Component​

The CopyIcon.tsx file is a React component that provides a user interface element for copying text to the clipboard.

Open the src/components/CopyIcon.tsx file with your code editor and modify the file as follows:

src/components/CopyIcon.tsx
import React from "react";

const CopyIcon: React.FC = () => (
  <svg
    fill="#000000"
    height="16"
    width="16"
    version="1.1"
    id="Layer_1"
    xmlns="http://www.w3.org/2000/svg"
    viewBox="0 0 64 64"
    enableBackground="new 0 0 64 64"
  >

    </g>
  </svg>
);

export default CopyIcon;

Step 8: Creating the Report Form Component​

The ReportForm.tsx file is a React component that renders a form for users to input parameters such as Ethereum addresses and date ranges. This form is used to generate specific transaction reports based on user input.

Open the src/components/ReportForm.tsx file with your code editor and modify the file as follows:

src/components/ReportForm
// src/components/ReportForm.tsx
import React, { useState } from "react";
import { viem } from "@quicknode/sdk";

interface ReportFormProps {
  onSubmit: (
    address: string,
    startDate: string,
    endDate: string,
    timezone: string
  ) => void;
  isLoading: boolean;
}

const ReportForm: React.FC<ReportFormProps> = ({ onSubmit, isLoading }) => {
  const [address, setAddress] = useState("");
  const [isValidAddress, setIsValidAddress] = useState(false);
  const [startDate, setStartDate] = useState(
    () => new Date().toISOString().split("T")[0]
  ); // default to today's date
  const [endDate, setEndDate] = useState(
    () => new Date().toISOString().split("T")[0]
  ); // default to today's date
  const [timezone, setTimezone] = useState("UTC");

  /* eslint-disable  @typescript-eslint/no-explicit-any */
  const handleAddressChange = (e: any) => {
    const inputAddress = e.target.value;
    setAddress(inputAddress);
    setIsValidAddress(viem.isAddress(inputAddress));
  };

  const handleSubmit = (e: React.FormEvent) => {
    e.preventDefault();
    onSubmit(address, startDate, endDate, timezone);
  };

  /* eslint-disable  @typescript-eslint/no-explicit-any */
  const timezones = (Intl as any).supportedValuesOf("timeZone") as string[];
  if (!timezones.includes("UTC")) {
    timezones.unshift("UTC");
  }

  return (
    <form onSubmit={handleSubmit} className="space-y-4">
      <div>
        <label htmlFor="address" className="block">
          Ethereum Address
        </label>
        <input
          type="text"
          id="address"
          name="address"
          value={address}
          onChange={handleAddressChange}
          className="border p-2 w-full"
          required
        />
        {!isValidAddress && address && (
          <div className="text-red-500">
            This is not a valid Ethereum address.
          </div>
        )}
      </div>
      <div className="flex space-x-3 ">
        <div>
          <label htmlFor="startDate" className="block">
            Start Date
          </label>
          <input
            type="date"
            id="startDate"
            name="startDate"
            value={startDate}
            onChange={(e) => setStartDate(e.target.value)}
            className="border p-2"
            required
          />
        </div>
        <div>
          <label htmlFor="endDate" className="block">
            End Date
          </label>
          <input
            type="date"
            id="endDate"
            name="endDate"
            value={endDate}
            onChange={(e) => setEndDate(e.target.value)}
            className="border p-2"
            required
          />
        </div>
        <div>
          <label htmlFor="timezone" className="block">
            Timezone
          </label>
          <select
            id="timezone"
            name="timezone"
            value={timezone}
            onChange={(e) => setTimezone(e.target.value)}
            className="border p-2"
          >
            {timezones.map((timezones) => (
              <option key={timezones} value={timezones}>
                {timezones}
              </option>
            ))}
          </select>
        </div>
      </div>
      <button
        type="submit"
        disabled={!isValidAddress}
        className={`${
          isValidAddress ? "bg-blue-500" : "bg-gray-500 cursor-not-allowed"
        } text-white px-4 py-2 rounded`}
      >
        {isLoading ? "Loading..." : "Generate"}
      </button>
    </form>
  );
};

export default ReportForm;

Step 9: Creating the Result Table Component​

The ResultTable.tsx file is a React component that displays the transaction report data in a tabular format, making it easy for users to read and analyze the information.

Open the src/components/ResultTable.tsx file with your code editor and modify the file as follows:

src/components/ResultTable.tsx
import React from "react";
import { ExtendedResult } from "../interfaces.ts";
import CopyIcon from "./CopyIcon.tsx";
import { exportAsCSV, copyAsCSV } from "../helpers/convertToCsv.ts";

interface ResultsTableProps {
  data: ExtendedResult;
}

function shortenAddress(address: string) {
  if (address.length < 10) {
    return address;
  }
  return `${address.slice(0, 5)}...${address.slice(-4)}`;
}

function copyToClipboard(text: string) {
  navigator.clipboard.writeText(text).then(
    () => {
      console.log("Copied to clipboard!");
    },
    (err) => {
      console.error("Could not copy text: ", err);
    }
  );
}

const ResultsTable: React.FC<ResultsTableProps> = ({ data }) => {
  return (
    <div className="overflow-x-auto mt-6">
      <div>
        <h3>Address: {data.address}</h3>
        <p>Current Balance: {parseFloat(data.balance) / 1e18} ETH</p>
        <p>Nonce: {data.nonce}</p>
        <p>Total Transactions: {data.txs}</p>
        <p>Non-Token Transactions: {data.nonTokenTxs}</p>
        <p>Internal Transactions: {data.internalTxs}</p>
      </div>
      <div className="my-4 flex space-x-4">
        <button
          onClick={() => exportAsCSV(data.extractedTransaction)}
          className="bg-blue-500 text-white px-4 py-2 rounded"
        >
          Export as CSV
        </button>
        <button
          onClick={() => copyAsCSV(data.extractedTransaction)}
          className="bg-blue-500 text-white px-4 py-2 rounded"
        >
          Copy as CSV
        </button>
      </div>
      <table className="min-w-full table-fixed text-xs">
        <thead className="bg-blue-100">
          <tr>
            <th className="p-2 text-center">Day</th>
            <th className="p-2 text-center">Time</th>

        </thead>
        <tbody>
          {data.extractedTransaction.map((tx, index) => (
            <tr key={index} className="border-t">

          ))}
        </tbody>
      </table>
    </div>
  );
};

export default ResultsTable;

Step 10: Assembling the Application​

The App.tsx file serves as the main component of your React application. It imports and uses the ReportForm.tsx and ResultTable.tsx components to create a cohesive user interface. It also manages the state and handles user input submission.

Open the src/App.tsx file with your code editor and modify the file as follows:

src/App.tsx
// src/App.tsx
import React, { useState } from "react";
import "./index.css";
import ReportForm from "./components/ReportForm.tsx";
import ResultTable from "./components/ResultTable.tsx";
import { bb_getAddress } from "./helpers/blockbookMethods.ts";
import { calculateVariables } from "./helpers/calculateVariables.ts";
import { ExtendedResult, CalculateVariablesOptions } from "./interfaces.ts";
import { DateTime } from "luxon";

const App = () => {
  const [reportData, setReportData] = useState<ExtendedResult | null>(null);
  const [loading, setLoading] = useState<boolean>(false);

  const handleFormSubmit = (
    address: string,
    startDate: string,
    endDate: string,
    timezone: string
  ) => {
    setLoading(true); // Start loading

    const configStartDate = DateTime.fromISO(startDate, {
      zone: timezone,
    });

    const configEndDate = DateTime.fromISO(endDate, {
      zone: timezone,
    });

    const options: CalculateVariablesOptions = {
      startDate: configStartDate,
      endDate: configEndDate,
      userTimezone: timezone,
    };

  1. Generate Report:
  • Click the "Generate" button to fetch and process the transaction data based on the input criteria.
  1. View Results:
  • The transaction data will be displayed in a table format below the form. This table includes details such as the date, time, block number, transaction ID, transaction status, type, asset, sender and receiver addresses, amount, token ID, fees, and method name/ID.
  1. Export or Copy Data:
  • Export as CSV: Click the "Export as CSV" button to download the transaction data as a CSV file.
