Blockchain Development Simplified with a Unified API

Blockchain development is often seen as complex and fragmented, especially when working across networks like Bitcoin, Solana, and Ethereum. Developers face challenges with diverse protocols, real-time monitoring, and transaction management. This is where Blockchain Development Simplified comes into play. By using a Unified Blockchain API, developers can streamline their workflows, reduce complexity, and accelerate innovation—all through a single, powerful interface.

To address these pain points, I created the Blockchain API. This Node.js-based solution provides a single interface to interact seamlessly with Bitcoin, Solana, and Ethereum. Whether you’re building a cryptocurrency wallet, a blockchain explorer, or a DeFi app, the Blockchain API streamlines development and accelerates innovation.

The Challenges of Blockchain Development Across Network

Working with multiple blockchain networks introduces several challenges:

• Diverse Protocols: Bitcoin uses UTXOs, Solana relies on lamports, and Ethereum works with accounts and smart contracts. Each demands unique handling.
• Real-Time Monitoring: Tracking events like transaction confirmations or balance changes requires different mechanisms for each network.
• Transaction Management: Building and submitting transactions involves different data formats, fee structures, and network-specific nuances.

These challenges increase development time and complexity, making multi-blockchain applications difficult to scale.

Introducing the Unified Blockchain API: Simplify Bitcoin, Solana, and Ethereum Interactions

The Blockchain API addresses these challenges by providing a developer-friendly, unified interface for Bitcoin, Solana, and Ethereum. Its modular architecture enables scalability and extensibility, making it easy to add support for future blockchains.

Technical Overview of the Unified Blockchain API

1. How the Unified Blockchain API Works

Each blockchain service (Bitcoin, Solana, Ethereum) is encapsulated in its own module, ensuring clean separation of concerns and easy maintenance. An Express-based API gateway exposes RESTful endpoints to handle client requests.

2. Real-Time Monitoring Across Blockchains

Bitcoin Service

The Bitcoin module interacts with the Blockchair API for transaction details, UTXOs, and fee estimates.

• Fetch Transaction Details:

const getTransactionDetails = async (txid) => {
  const url = `https://api.blockchair.com/bitcoin/dashboards/transaction/${txid}`;
  const response = await axios.get(url);
  return response.data;
};

• Manage UTXOs:

const getUTXOs = async (address) => {
  const url = `https://api.blockchair.com/bitcoin/outputs?q=recipient(${address})`;
  const response = await axios.get(url);
  return response.data.data;
};

Solana Service

The Solana module uses Web3.js for RPC interactions and WebSocket subscriptions for real-time updates.

• Check Account Balance:

const getBalance = async (address) => {
  const connection = new web3.Connection(web3.clusterApiUrl('mainnet-beta'));
  const balance = await connection.getBalance(new web3.PublicKey(address));
  return balance / web3.LAMPORTS_PER_SOL;
};

• Real-Time Updates:

const subscribeAccountChanges = (address) => {
  const connection = new web3.Connection(web3.clusterApiUrl('mainnet-beta'), 'confirmed');
  connection.onAccountChange(new web3.PublicKey(address), (accountInfo) => {
    console.log('Account updated:', accountInfo);
  });
};

Ethereum Service

The Ethereum module integrates Alchemy and Infura APIs to support account and transaction management.

• Fetch the First Transaction Hash:

const getFirstTransactionHash = async (address) => {
  const response = await axios.post(alchemyUrl, {
    jsonrpc: "2.0",
    method: "alchemy_getAssetTransfers",
    params: [{ fromBlock: "0x0", toBlock: "latest", toAddress: address, category: ["external"], maxCount: "0x1" }],
    id: 1,
  });
  return response.data.result.transfers[0]?.hash || null;
};

• Send Ethereum Transactions:

const sendTransaction = async (fromAddress, privateKey, toAddress, amount) => {
  const web3 = new Web3(INFURA_URL);
  const nonce = await web3.eth.getTransactionCount(fromAddress, "latest");
  const tx = {
    from: fromAddress,
    to: toAddress,
    value: web3.utils.toWei(amount.toString(), "ether"),
    gas: await web3.eth.estimateGas({ from: fromAddress, to: toAddress, value: web3.utils.toWei(amount.toString(), "ether") }),
    gasPrice: await web3.eth.getGasPrice(),
    nonce,
  };
  const signedTx = await web3.eth.accounts.signTransaction(tx, privateKey);
  const receipt = await web3.eth.sendSignedTransaction(signedTx.rawTransaction);
  return receipt.transactionHash;
};

Key Benefits of Using a Unified Blockchain API for Developers

1. Simplified Development

Developers no longer need to integrate multiple libraries or APIs. The Blockchain API handles all the complexities of interacting with Bitcoin, Solana, and Ethereum.

2. Real-Time Monitoring

WebSocket-based updates ensure instant notifications for account changes or transaction confirmations.

3. Cross-Network Compatibility

Uniform endpoints allow developers to build applications that interact with multiple blockchains without worrying about network-specific protocols.

4. Extensibility

The modular architecture makes it easy to add support for new blockchains like Polygon or Binance Smart Chain in the future.

Getting Started with the Blockchain API: A Developer’s Guide

Here’s how to use the Blockchain API:

1. Clone the Repository

git clone https://github.com/rick001/blockchain-api.git

2. Install Dependencies

npm install

3. Set Environment Variables

Configure the .env file with API keys for Blockchair, Alchemy, and Infura.

4. Run the Server

node server.js

5. Access the Endpoints

• • Bitcoin Transaction Details: /bitcoin/transaction/:txid
  • Solana Account Balance: /solana/balance/:address
  • Ethereum Transaction Hash: /ethereum/transaction/:hash

Future of Blockchain Development: Scaling Beyond Bitcoin, Solana, and Ethereum

While the Blockchain API currently supports Bitcoin, Solana, and Ethereum, future enhancements will include:

• Smart Contract Interactions: Enabling developers to read and write data to Ethereum smart contracts.
• Support for Additional Blockchains: Expanding compatibility to include Polygon, Binance Smart Chain, and Avalanche.
• Advanced Features: Implementing transaction batching and analytics tools for gas fee optimization.
