Parameters

• address — the address to check the balance of.

• quantity or tag — the integer of a block encoded as hexadecimal or the string with:

  • latest — the most recent block in the blockchain and the current state of the blockchain at the most recent block. A chain reorganization is to be expected.

  • safe—the block that received justification from the beacon chain. Although this block could be involved in a chain reorganization, it would necessitate either a coordinated attack by the majority of validators or severe propagation latency.

  • finalized — the block accepted as canonical by more than 2/3 of the validators. A chain reorganization is extremely unlikely, and it would require at least 1/3 of the staked ETH to be burned.

  • earliest — the earliest available or genesis block

  • pending— the pending state and transactions block. This is the current state of transactions that have been broadcast to the network but have not yet been included in a block.

Response

• quantity — the integer value of the current balance in Wei

eth_getBalance code examples

const { Web3 } = require("web3");
const NODE_URL = "CHAINSTACK_NODE_URL";
const web3 = new Web3(NODE_URL);

async function getBalance(address, block) {
  const balance = await web3.eth.getBalance(address, block)
  console.log(balance)
 }
 
 getBalance("0x038D8981cC8fB8421CB96e8EEe8093Fc1F2E63dC", "latest" )

const ethers = require('ethers');
const NODE_URL = "CHAINSTACK_NODE_URL";
const provider = new ethers.providers.JsonRpcProvider(NODE_URL);

const getBalance = async (address, block) => {
    const balance = await provider.send("eth_getBalance", [address, block]);
    console.log(balance);
  };

getBalance("0x038D8981cC8fB8421CB96e8EEe8093Fc1F2E63dC", "latest")

from web3 import Web3  
node_url = "CHAINSTACK_NODE_URL" 

address = web3.to_checksum_address("0x038D8981cC8fB8421CB96e8EEe8093Fc1F2E63dC")
balance = web3.eth.get_balance(address, "latest") 
print(balance) 

Use case

One practical use case for eth_getBalance is to check the balance of an account for a program that scans the balance periodically and fills up the account when the balance drops below a certain value.
