Description

Returns the balance of a given address as of the provided block.

Parameters

blockTag parameters

• pending - A sample next block built by the client on top of latest and containing the set of transactions usually taken from local mempool. Intuitively, you can think of these as blocks that have not been mined yet.
• latest - The most recent block in the canonical chain observed by the client, this block may be re-orged out of the canonical chain even under healthy/normal conditions.
• safe - The most recent crypto-economically secure block, cannot be re-orged outside of manual intervention driven by community coordination. Intuitively, this block is “unlikely” to be re-orged. Only available on Ethereum Goerli.
• finalized - The most recent crypto-economically secure block, that has been accepted by >2/3 of validators. Cannot be re-orged outside of manual intervention driven by community coordination. Intuitively, this block is very unlikely to be re-orged. Only available on Ethereum Goerli.
• earliest - The lowest numbered block the client has available. Intuitively, you can think of this as the first block created.

4
// Configures the Alchemy SDK
5
const config = {
6
    apiKey: "alchemy-replit", // Replace with your API key
7
    network: Network.ETH_MAINNET, // Replace with your network
8
};
9
10
// Creates an Alchemy object instance with the config to use for making requests
11
const alchemy = new Alchemy(config);
12
13
const main = async () => {
14
  	// This response fetches the balance of the given address in the paramter as of the provided block.
15
    let response = await alchemy.core.getBalance("vitalik.eth", "latest")
16
17
    //Logging the response to the console
18
    console.log(response)
19
};
