How to Build Sites Similar to Etherescan with Moralis’ Web3 API Suite 

Now that you have familiarized yourself with Moralis’ Web3 API suite, we’ll take this section to explore some prominent endpoints that can come in handy when building sites similar to Etherscan. Moreover, to do so, we need to start by identifying some key features of block explorers! 

Etherscan lets you explore most aspects of the Ethereum blockchain, including block data, token prices, wallet transactions, balances, etc. However, let’s look at a couple of concrete examples below: 

  • Exploring Block Data: A central feature of Etherscan is that you can look up the contents of any block. To do so, click on one of the blocks on the Etherscan landing page:

Doing so displays a bunch of information, including the block’s timestamp, transactions, gas used, gas limit, and much more:

  • Look Up Wallet Addresses: Another feature is that you can look up any address using Etherscan. To do so, simply input any address into the search field at the top:

Searching an address on Etherscan takes you to a page looking something like this where you 1) get an overview field showing the native balance, value in USD, and all tokens of the account and 2) can view all transactions, internal transactions, token transfers, NFT transfers, etc.:

All in all, blockchain explorer sites like Etherscan display block data, token prices, native balances, transactions, transfers, and more! 

So, how can you get this information? 

The easiest way to fetch and integrate data like this into your Web3 projects is to leverage Moralis’ various APIs. And we’ll show you exactly how this works in the following sections! 

Get Block Data with the Blockchain API 

With the Blockchain API, you can effortlessly get the contents of any block with a single call to the getBlock() endpoint. All you have to do is specify two parameters: chain and blockNumberOrHash

const response = await Moralis.EvmApi.block.getBlock({
  "chain": "0x1",
  "blockNumberOrHash": "15863321"
});

In return for calling the endpoint, you get a response containing the block’s timestamp, number hash, log blooms, transactions, gas used, gas limit, etc. Here’s an example of what the response might look like: 

{
  "timestamp": "2022-10-30T20:39:11.000Z",
  "number": "15863321",
  "hash": "0x4f5d3bb78f0311301ef282b281d23e178ced236a7ae465820fe6edeba609954a",
  "parent_hash": "0x27e61d430386d7b4a144bee6e120a57010fbdb3cf963ca37e2d20b5452203621",
  "nonce": "0x0000000000000000",
  "sha3_uncles": "0x1dcc4de8dec75d7aab85b567b6ccd41ad312451b948a7413f0a142fd40d49347",

  "state_root": "0xcb1df24273693eb33869961233baac112adbdf51e980e5cf8b8aa7084e8063be",
  "receipts_root": "0x3a3d89417ad3898d47f66155e0e5fdf3e1efde2a6f389e7b051acf729db28617",
  "miner": "0x388C818CA8B9251b393131C08a736A67ccB19297",

  "extra_data": "0x",
  "gas_limit": "30000000",
  "gas_used": "19044124",
  //...
}

Fetch Native Balances with the Wallet API 

The Wallet API lets you fetch the native balance of any wallet with a single call to the getNativeBalance() endpoint. You simply need to add two parameters: chain and address

const response = await Moralis.EvmApi.balance.getNativeBalance({
  "chain": "0x1",
  "address": "0x057Ec652A4F150f7FF94f089A38008f49a0DF88e"
});

Calling the getNativeBalance() endpoint will give you a simple response showing the native balance of the wallet in question. This is what the response might look like: 

{
  "balance": "123322"
}

Query Token Prices with the Token API 

With the Token API, you can get the price of any token with a single call to the getTokenPrice() endpoint. All you have to do is specify a chain parameter and add a token’s address to address

const response = await Moralis.EvmApi.token.getTokenPrice({
  "chain": "0x1",
  "address": "0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0"
});

In return for calling the endpoint above, you’ll get a response with the price denominated in the chain’s native token and USD. This is what it can look like: 

{
  "tokenName": "Matic Token",
  "tokenSymbol": "MATIC",
  "tokenLogo": "https://cdn.moralis.io/eth/0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0.png",
  "tokenDecimals": "18",
  "nativePrice": {
    "value": "407101727793637",
    "decimals": 18,
    "name": "Ether",
    "symbol": "ETH",
    "address": "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2"
  },
  "usdPrice": 0.7680647947395282,
  "usdPriceFormatted": "0.768064794739528156",
  "exchangeName": "Uniswap v3",
  "exchangeAddress": "0x1F98431c8aD98523631AE4a59f267346ea31F984",
  "tokenAddress": "0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0"
}

Get All Tokens of a Wallet with the Token API 

The Token API also lets you get all tokens owned by a specific wallet. All you need to do is call the getWalletTokenBalances() endpoint while passing along two parameters: chain and address

const response = await Moralis.EvmApi.token.getWalletTokenBalances({
  "chain": "0x1",
  "address": "0x1f9090aaE28b8a3dCeaDf281B0F12828e676c326"
});

In return for calling the getWalletTokenBalances() endpoint, you get an array of all tokens held by the wallet in question. Here’s an example of what it might look like: 

[
  {
    "token_address": "0x3c978fc9a42c80a127863d786d8883614b01b3cd",
    "symbol": "USDT",
    "name": "USDTOKEN",
    "logo": null,
    "thumbnail": null,
    "decimals": 18,
    "balance": "10000000000000000000000",
    "possible_spam": true
  },
  //...
]

The Token API also features advanced spam detection, marking tokens as possible_spam if they are potential scam coins. This is a neat feature, allowing you to seamlessly filter through the array and remove any suspicious coins so your end user doesn’t have to deal with them:

Query All Transactions of a Wallet with the Wallet API 

With the Wallet API, you can seamlessly fetch all transactions of a wallet with a single call to the getWalletTransactions() endpoint. All you have to do is pass along two parameters: chain and address

const response = await Moralis.EvmApi.transaction.getWalletTransactions({
  "chain": "0x1",
  "address": "0x1f9090aaE28b8a3dCeaDf281B0F12828e676c326"
});

In return for calling the endpoint above, you get an array of all transactions of the specified wallet. Here’s an example of what the response might look like: 

[
	//...
    {
      "hash": "0x59034c908cc483eea265dfa359e9cca4d65534f6a27af68c04ae085636b49843",
      "nonce": "351249",
      "transaction_index": "167",
      "from_address": "0x1f9090aae28b8a3dceadf281b0f12828e676c326",
      "from_address_label": "rsync-builder",
      "to_address": "0x388c818ca8b9251b393131c08a736a67ccb19297",
      "to_address_label": "Lido: Execution Layer Rewards Vault",
      "value": "292138497314265085",
      "gas": "22111",
      "gas_price": "35862701891",
      "input": "0x",
      "receipt_cumulative_gas_used": "24862993",
      "receipt_gas_used": "22111",
      "receipt_contract_address": null,
      "receipt_root": null,
      "receipt_status": "1",
      "block_timestamp": "2023-11-08T12:56:35.000Z",
      "block_number": "18527378",
      "block_hash": "0xd0de438f288648120b7172c17108b70071810ee5a8fcbd24bee451c7e2a6dd19",
      "transfer_index": [
        18527378,
        167
      ]
    },
    //...
]

Also, all transaction and transfer endpoints have address labels. With this feature, you can significantly improve the user experience of your dapps by effortlessly displaying human-readable labels rather than long, bothersome addresses involved in all transactions:
