How to use it

// yarn add @tatumio/tatum

import { TatumSDK, AvalancheC, Network } from '@tatumio/tatum'

const tatum = await TatumSDK.init<AvalancheC>({ network: Network.AVALANCHE_C })

const balance = await tatum.rpc.getBalance('0xa41d19F4258a388c639B7CcD938FCE3fb7D05e86')

Overview

The eth_getBalance method is an JSON-RPC method that allows you to retrieve the balance of a specified address. This method can be used to query the balance of any address, whether it is a contract or an externally owned account (EOA). A common use case for this method is to display the current balance of a user's account in a wallet application or a decentralized application (DApp).

Parameters

The method requires two parameters:

address (required): The address of the account or contract whose balance you want to query.
- Example: "0x742d35Cc6634C0532925a3b844Bc454e4438f44e"
blockParameter (optional): The block number or block identifier to specify the point in time for which you want to query the balance.
- Example: "latest" or "0x1"

Transaction Details

For the purpose of this documentation, we'll also describe the transactions field of a full transaction object. The eth_getBalance method does not return transaction details, but we provide this information for completeness.

A full transaction object includes the following fields:

hash: The transaction hash.
nonce: The number of transactions made by the sender prior to this one.
blockHash: The hash of the block in which the transaction was included.
blockNumber: The block number in which the transaction was included.
transactionIndex: The index of the transaction in the block.
from: The sender's address.
to: The recipient's address (or null for contract creation transactions).
value: The value transferred, in wei.
gasPrice: The gas price provided by the sender, in wei.
gas: The maximum gas allowed for the transaction.
input: The data sent with the transaction (typically for contract interaction).
v, r, s: The raw signature values of the transaction.

Return Object

The method returns a single field:

result: The Flare balance of the specified address in wei, as a hexadecimal string.
- Example: "0x1a2e1a", which corresponds to 1,726,666 wei.
