getBalance

The getBalance RPC method provides a simple and efficient way to retrieve the native SOL balance of any account on the Solana blockchain. The balance is returned in lamports.

The getBalance RPC method provides a simple and efficient way to retrieve the native SOL balance of any account on the Solana blockchain. The balance is returned in lamports, where 1 SOL = 1,000,000,000 lamports. Unlike getAccountInfo, which returns detailed metadata, getBalance is ideal for lightweight balance checks.

🎯 Primary Use Case

• Quick SOL Balance Check Instantly determine how much SOL an account—such as a wallet or program-owned address—holds.

🛠 Parameters

• publicKey (string, required): The base-58 encoded public key of the account to query.

• config (object, optional): Optional fields to control query behavior:

  • commitment (string): Determines the commitment level for the request:

    • finalized (default) – Highest level of confirmation.

    • confirmed – Recent vote-confirmed block.

    • processed – Most recent block (possibly unconfirmed).

  • minContextSlot (number): Minimum slot at which the query may be evaluated.

Sample Request (CoinVera RPC):

Nodejs

const fetch = require('node-fetch');

async function getBalance(rpcUrl) {
  try {
    const response = await fetch(rpcUrl, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        jsonrpc: '2.0',
        id: 1,
        method: 'getBalance',
        "params": [
            "4UJuvGZ7Ge8H3je63Nsb9ZRNVBAd3CG2ajibnRaVSbw5"
          ]
      }),
    });

    const data = await response.json();
    
    // Print the exact full response
    console.log('Full RPC Response:');
    console.log(JSON.stringify(data, null, 2));
    
    return data;
  } catch (error) {
    console.error('Error getting health:', error.message);
    return null;
  }
}

// Example usage
const RPC_URL = 'https://rpc.coinvera.io/?x-api-key=your-coinvera-x-api-key';

getBalance(RPC_URL);

Python

import json
import asyncio
import aiohttp

async def get_balance(rpc_url):
    try:
        payload = {
            "jsonrpc": "2.0",
            "id": 1,
            "method": "getBalance",
            "params": [
                "4UJuvGZ7Ge8H3je63Nsb9ZRNVBAd3CG2ajibnRaVSbw5"
            ]
        }
        
        async with aiohttp.ClientSession() as session:
            async with session.post(
                rpc_url,
                headers={'Content-Type': 'application/json'},
                json=payload
            ) as response:
                data = await response.json()
                
                # Print the exact full response
                print('Full RPC Response:')
                print(json.dumps(data, indent=2))
                
                return data
                
    except Exception as error:
        print(f'Error getting health: {error}')
        return None

# Example usage
async def main():
    RPC_URL = 'https://rpc.coinvera.io/?x-api-key=your-coinvera-x-api-key'
    await get_balance(RPC_URL)

# Run the async function
if __name__ == "__main__":
    asyncio.run(main())

🧠 Developer Tips (with CoinVera)

• Use getBalance for Simplicity When you only need SOL balance, this method is significantly lighter than getAccountInfo and avoids unnecessary data transfer.

• Account Existence Check If the account hasn't been initialized on-chain, getBalance returns 0. This makes it a quick way to check if an account exists for balance purposes only.

• Convert Lamports to SOL Don’t forget: divide the result by LAMPORTS_PER_SOL (1,000,000,000) to display balances in SOL.

• Commitment Strategy Choose your commitment level based on the application:

  • confirmed – Best for UI and general info.

  • finalized – Best for financial or high-assurance operations. See Solana’s commitment model for more on consistency vs. speed.

• Scaling with getMultipleAccounts Need balances for multiple accounts? While getBalance only handles one at a time, using getMultipleAccounts and extracting lamport balances can be more efficient at scale.
