In today's blockchain ecosystem, having access to real-time data is not just a luxury - it's a necessity. ZettaBlock's Prebuilt APIs are designed to meet this demand head-on. These real-time APIs provide the foundational building blocks for asset management, enabling seamless transactions, balance tracking, and real-time data analytics.

With just a few lines of GraphQL code, you can effortlessly integrate these functionalities into your application, enhancing both user experience, user engagements and operational efficiency.

A Practical Example: Fetching Native Balance

Let's dive into a real-world example. Say you want to fetch the native balance of a specific blockchain address. Traditionally, this would involve multiple steps and potential errors. With ZettaBlock, it's as simple as executing the following GraphQL queries:

query {
  native_balance(address: "0x...")
}

query {  
  token_balances(  
    where: {address: {eq: "0xd8da6bf26964af9d7eed9e03e53415d37aa96045"}}  
  	first:20  
    orderBy: value  
    orderDirection:desc  
  ) {  
    value  
    contract_address  
    token_metadata {  
      name  
      symbol  
    }  
  }  
}

The Traditional Way: Using RPC Node for Wallet Balance

In contrast, using an RPC node to get the same information is a cumbersome process. You'd first need to identify the wallet address and the ERC20 token contract address/addresses. Then, you'd have to create a data parameter using the Keccak hash of balanceOf(address) for each ERC20 and execute an eth_call to the Ethereum RPC node. After all these steps, you'd still need to decode the hex-encoded response (in some cases) to get the actual balance. It's not just time-consuming but also error-prone.

Why ZettaBlock Stands Out

What sets ZettaBlock apart is its commitment to simplifying complex processes. With our Prebuilt APIs, you can:

• Eliminate multiple steps in fetching data and decoding it.
• Reduce the risk of errors and maintain better data quality, all in real time.
• Accelerate development cycles.
