💡 Developer Tips

• Only Works on Token Accounts This method only accepts token account addresses, not general wallet addresses. Use getTokenAccountsByOwner first if needed.

• Lamports ≠ Token Amounts Unlike SOL balances, token balances vary in decimal precision—always respect the decimals value.

• String for Precision Use uiAmountString in UIs to avoid rounding errors, especially for large or small balances.

• Commitment Matters Add commitment: "finalized" if you need the most reliable confirmed result.

The getTokenAccountBalance method is essential for tracking SPL token balances in real-time, especially in dApps, wallets, and trading bots built on CoinVera.
