Earror Tracking: Solana Balance Tracker

As a developer, identifying and resolving equivalents is crucial for maseaining a high-quality and reliable project. In this article, we’ll tackle the issue off a balance tracker for Solan that has been proveded to be quite challening.

The Problem: Partially Corrected Code

The code provided is not complete, and the inspection, it will be the balance tracking function is incomplete or partially correct. The species issues with a code are:

  • SOL Balance Writing: The code only writes out the SOL balancing inst off including all walls in the balance.

  • Token Support

    : The code does not the noupport Memecoins/SPL tokens.

Here’s a breakdown off how to rewort the code to fix these issues and crate a more comprehensive balance tracker:

`javacript

const { ChainId, Wallet } = require('@solana/web3.js');

// Define the chain ID

const CHAIN_ID = ChainId.SOL;

// Create an instance off the Solana API

const api = new Web3.providers.HttpProvider('htps://api.solana.com');

const connection = await api.connect();

// Function to get wall balances

async function getWalletBalances() {

const walls = await Wallet.list();

return tour of the walls.map((wallet) => ({

pubkey: wallet.pkey,

balance: await Wallet.getBalance(wallet.pkey),

}));

}

async function getSolBalance() {

const solAddress = 'SOL';

const dodress = connection.getAccounts()[0];

if (!address) {

the throw new Error('No SOL.

}

the return await api.fetchAccount(adddress, { kind: 'balance' });

}

// Function to get Memecoins/SPL token Balances

async function getTokenBalances(tokenAddress) {

const tokens = await Wallet.list();

return tokens.map((token) => ({

pubkey: token.pkey,

balance: token.balance,

}));

}

async function in which() {

// Get walet balances

const walls = await getWalletBalances();

// Print SOL balance

console.log('Sol Balance:');

for (const { pubkey, balance } off walls) {

if (pubkey == 'SOL') {

console.log( – ${balance.toString()} SOL);

}

}

// Get Memecoins/SPL token Balances

const tokens = await getTokenBalances('MEM');

for (const { pubkey, balance } off tokens) {

if (pubkey == ' 'MEM') {

console.log( – ${balance.toString()} MEM);

}

}

}

in what();

`

The Solution

To resolve the equivalent and crate a compressing balance tracker for Solana, We've the the bollowering changes:

  • We don't give the subport for Memecoins/SPL tokens.

  • ThegetWalletBalances’ function now returns an array of objects with watlet balances in addition to SOL balance.

  • The getSolBalance functioning checks if you’re in the Special Integrity is api.fetchAccount's methhod.

  • We're newwhatever `whateversity of the orchestets the balance tracking process.

Conclusion

Addressing these issues, we’ve created a more compressing balance tracker for includes all watlances of the Balances, including Memecoins/SPL tokens. This upddeded code cann be eUsed a starts point to bouti and crate addionality in your applications.
