Using EVMExplorer-Blockscout SDK

Fetching a Transaction

To fetch a transaction on Ethereum mainnet as demonstrated on Ethereum Stack Oveflow answer:

import type { TransactionBlockscout } from '@evmexplorer/blockscout';
import { fetchTransactionBlockscout } from '@evmexplorer/blockscout';

const data: TransactionBlockscout = await fetchTransactionBlockscout(
  '0xdc7ddf3d0e53532eeeda7a7a99c88255ccee5a3b4404441278cbbd79b4c85086',
);

console.log(data);

Output

The fetchTransactionBlockscout function returns an object with the following properties:

Fetching Vitalik's Address Tokens

You can also query the blockchain address token balances as demonstrated on Stack Overflow. For example, let's query Vitalik's balances:

export type { AddressTokens } from "@evmexplorer/blockscout";
export { fetchTokensAddress } from "@evmexplorer/blockscout";

const data: AddressTokens = await fetchTokensAddress(
  '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045',
);
console.log(data.length)
console.log(data[0])

Address Tokens Output

6081
{
  token: {
    address: '0x28561B8A2360F463011c16b6Cc0B0cbEF8dbBcad',
    circulating_market_cap: '75858317.61202328',
    decimals: '9',
    exchange_rate: '0.00017784',
    holders: '14334',
    icon_url: 'https://assets.coingecko.com/coins/images/50348/small/1000000612.jpg?1727248974',

    type: 'ERC-20',
    volume_24h: '10219755.637613483'
  },
  token_id: null,
  token_instance: null,
  value: '30000105889157756560'
}

Vitalik has 6081 tokens. The first token in the array of all 6081 tokens is Moo Deng token.

Fetching Latest Block Transactions

You can also query the latest block transactions with Ethers provider as demonstrated on Stack Overflow.

import { fetchBlockTransactionsBlockscout } from '@evmexplorer/blockscout';
const block = await provider.getBlock();
const data = await fetchBlockTransactionsBlockscout(block);
