How to fix “OUT OF ENERGY” error on TRON Transfers?
When making TRC20 contract calls on the TRON network — such as transferring Tether (USDT) — you might have encountered the frustrating error:
❌ FAILED - OUT OF ENERGY
This message indicates that your transaction lacked sufficient energy, a key resource required for executing smart contract operations on TRON. Let’s break down why this happens and how to solve it — fast and efficiently.
Common Causes of the “OUT OF ENERGY” Error
1. Your Wallet Lacks Energy
Every contract interaction on TRON consumes Energy. If your wallet hasn’t staked TRX to earn energy or hasn’t obtained energy from external sources, it will rely on burning TRX instead. If neither resource is sufficient, you’ll encounter the error.
2. Not Enough TRX to Cover Fees
If your wallet lacks energy, TRON tries to burn TRX to compensate. For example:
Sending USDT to an address without USDT requires 130,285 Energy, which costs about 27.74 TRX.
Sending USDT to an address with USDT requires 64,285 Energy, around 13.7 TRX.
Without enough TRX, the transaction will fail.
3. Fee Limit Too Low in Programmatic Calls
If you're using a script or API to perform transactions and you’ve set a low feeLimit (e.g., 10 TRX), but the required fee is over 27 TRX, the transaction will fail due to insufficient resources.
How to Fix It?
✅ Option 1: Deposit More TRX
Make sure your wallet has enough TRX to cover burned energy costs. This works, but it’s expensive and inefficient in the long run.
✅ Option 2: Rent Energy Instantly via CatFee.IO
