Solana: Hello! I’m having trouble setting up the Solana balance tracker.

Bug Tracker: Solana Balance Tracker

As a developer, you need to identify and resolve bugs to maintain the quality and reliability of your project. In this article, we will address the issue of creating a balance tracker for Solana, which has proven to be quite a difficult task.

Issue: Partially corrected code

The provided code is not complete and upon closer inspection, it turns out that the balance tracker functionality is either incomplete or partially correct. The specific issues with the code are as follows:

• SOL Balance Saving

  : The code only saves the SOL balance instead of including the balances of all wallets.

• Token Support: The code does not support Memecoins/SPL tokens.

Here’s how to rewrite the code to fix these issues and create a more comprehensive balance tracker:

const { ChainId, Wallet } = require('@solana/web3.js');
// Define the chain identifier
const CHAIN_ID = ChainId.SOL;
// Create an instance of the Solana API
const api = new Web3.providers.HttpProvider('
const connection = await api.connect();
// Function to get wallet balances
asynchronous function getWalletBalances() {
const wallets = await Wallet.list();
return wallets.map((wallet) => ({
public key: wallet.pkey,
balance: await Wallet.getBalance(wallet.pkey),
}));
}
asynchronous function getSolBalance() {
const solAddress = 'SOL';
constant address = connection.getAccounts()[0];
if (!address) {
throw new Error('No SOL address found in wallets');
}
return await api.fetchAccount(address, { kind: 'balance' });
}
// Function to fetch Memecoins/SPL token balances
asynchronous function getTokenBalances(tokenAddress) {
const tokens = await Wallet.list();
return tokens.map((token) => ({
public key: token.pkey,
balance: token.balance,
}));
}
asynchronous function main() {
// Get wallet balance
const wallets = await getWalletBalances();
// Print SOL scale
console.log('Sun Balance:');
for (const { public key, balance } wallets) {
if (public key === 'SOL') {
console.log( - ${balance.toString()} SOL);
}
}
// Get Memecoins/SPL token balance
const tokens = await getTokenBalance('MEM');
for (const { public key, balance } tokens) {
if (public key === 'MEM') {
console.log(- ${balance.toString()} MEM);
}
}
}
main();

Solution

To resolve bugs and create a comprehensive balance tracker for Solana, we made the following changes:

• We added support for Memecoins/SPL tokens.

• The getWalletBalances function now returns an array of objects containing the wallet balance, in addition to the SOL balance.

• The getSolBalance function checks if a specific Solana address was found and retrieves its balance using the api.fetchAccount method.

• We created a new function “main” that coordinates the balance tracking process.

Conclusion

By addressing these issues, we have created a more comprehensive balance tracker for Solana that includes balances of all wallets, including Memecoins/SPL tokens. The updated code can now be used as a starting point for extensions and additional functionality in applications.
