When you initiate a transaction using the Tron cross-chain bridge, you need to encode the transaction information into a transaction memo. According to the latest protocol of the TRX network, each transaction requires bandwidth and energy as handling fees, and including a memo costs an additional 1 TRX. Therefore, if you lack sufficient energy and bandwidth, you may encounter transaction failures or error messages.
This guide explains how to properly manage these resources to ensure smooth transactions on the TRON network.
Why Is My Bandwidth Always Zero?
If your bandwidth shows zero, it means your account has not been activated yet. To activate it, simply transfer some TRX into your wallet. Once activated, your account will receive 600 bandwidth points for free every 24 hours.
After activation, initiating transactions—such as transfers—will consume bandwidth and energy resources. If your wallet doesn’t have enough available TRX to cover these costs, the transaction may fail or you might see an error message about insufficient bandwidth.
We recommend transferring 50–100 TRX into your wallet. This will activate your account and cover the resource requirements for future transactions.
What Are Bandwidth and Energy?
- Bandwidth refers to the byte size of a transaction. For example, a transfer transaction sized 250 bytes consumes 250 bandwidth points.
- Energy refers to the time required for smart contract execution, measured in microseconds (μs). If a smart contract takes 100 μs to execute, it consumes 100 energy points.
How to Get Bandwidth and Energy
Option 1: Burn TRX (Recommended)
Transfer 50–100 TRX tokens into your TRX wallet. When you make a transaction, a small amount of TRX will be automatically burned to cover the bandwidth and energy costs.
Option 2: Freeze TRX
Go to the "Resource Management" section on the asset homepage. In the TRON Resource interface, choose the type of resource you want (bandwidth or energy), and enter the amount of TRX you wish to freeze. It’s recommended to freeze 2000–3000 TRX. Frozen TRX can be unfrozen and retrieved after 3 days.
Important Notes:
- All transactions consume bandwidth.
- Some transactions, such as smart contract calls (including TRC-20 transfers and DApp interactions), also consume energy.
- An activated account receives 1500 free bandwidth points every 24 hours, which can be used for multiple TRX and TRC-10 token transfers each day.
- Resources obtained by freezing TRX will gradually recover over 24 hours after being consumed.
Frequently Asked Questions
Why did my TRON transaction fail even though I have TRX?
Your transaction may require more energy or bandwidth than your account currently has. Ensure you have enough resources by either freezing more TRX or keeping a balance to cover burning costs.
Can I use the free daily bandwidth for any transaction?
The free 1500 bandwidth points are suitable for standard TRX and TRC-10 token transfers. However, smart contract interactions and memo-included transactions require additional resources.
What happens if I don’t have enough energy?
Transactions requiring energy—such as interacting with dApps or TRC-20 tokens—will fail. You can acquire more energy by freezing TRX or ensuring you have enough TRX to burn.
Is freezing TRX better than burning it?
Freezing is ideal for frequent users as it provides recurring resources. Burning is simpler for occasional transactions since it doesn’t require locking funds.
How long does it take to unfreeze TRX?
Once you initiate an unfreeze, it takes 3 days for the TRX to become available in your wallet.
Can I use other wallets to get resources for imToken?
Yes, you can obtain resources in a compatible wallet like TP Wallet and then transfer assets to imToken. However, this adds extra steps and may not be efficient for regular use.

Summary
Managing bandwidth and energy is essential for executing transactions on the TRON network. By activating your account, maintaining a sufficient TRX balance, or freezing tokens, you can avoid common errors and ensure smooth operations. Whether you choose to burn TRX for immediate needs or freeze for long-term benefits, understanding these mechanisms helps optimize your blockchain activities.
Always remember that resource requirements can vary based on transaction type and network conditions. Stay informed and prepare accordingly to make the most of your imToken wallet.
