Blockchain data

ChainGate offers additional blockchain data endpoints that let you explore the state of various networks beyond your own addresses. This includes:

  • Transaction details
  • Latest blocks
  • Block transactions
  • ...and more.

You can access these endpoints through the BlockchainData class.

Quick example​

import { BlockchainData } from 'chaingate'

async function fetchBlockchainInfo() {
  // Instantiate with your API key
  const blockchainData = new BlockchainData('your-api-key')

  // Get transaction details (Bitcoin example)
  const txDetails = (await blockchainData.BitcoinApi.transactionDetails('e9a66845...')).data
  console.log('Transaction details:', txDetails)

  // Get the latest Ethereum block
  const ethLatestBlock = (await blockchainData.EthereumApi.latestBlock()).data
  console.log('Latest Ethereum block:', ethLatestBlock)
}

Available APIs​

Each supported blockchain includes its own set of APIs under the BlockchainData class (e.g., BitcoinApi, EthereumApi, etc.). You can call methods to retrieve detailed information about transactions, blocks, mempools, and more.

Key points​

  • Independent of wallet: These calls do not require an initialized wallet. They query blockchain data directly from ChainGate’s services.
  • Multiple chains: A single BlockchainData instance can access endpoints for multiple blockchains.
  • Exploration: Use these methods to build explorer-like functionality or perform in-depth network analysis.
  • Security: You only need your API key. No private keys or mnemonic phrases are involved in reading blockchain data.
