# Why Does the Transfer Fail Even After Renting Energy on TRON?

Even if you’ve already rented energy, your transfer might still fail. Below are some common reasons and suggested solutions to help you troubleshoot the issue:

***

#### 1. **Insufficient Energy**

Although you've rented energy, the actual transfer may require **more energy than expected**, especially in cases where:

* The **recipient address has no USDT**, or
* The network is **congested** and resource demands are high.

For example, transferring to an address **without USDT** usually requires **130,285 Energy**. If your rented energy is below this threshold, the transaction may fail.

**Solution:**

* Check whether your rented energy is enough, especially when the destination address has no USDT.
* Consider increasing your rented energy through platforms like [**CatFee.IO**](https://catfee.io/) to ensure the transaction completes successfully.

***

#### 2. **Insufficient Bandwidth**

The TRON network also requires a certain amount of **Bandwidth** to process transactions. If bandwidth is lacking, especially for **TRC-20 token transfers** like USDT, the transaction may fail.

**Solution:**

* Ensure you have sufficient bandwidth.
* If not, you can **freeze TRX** to gain bandwidth, or **purchase additional bandwidth**.

***

#### 3. **Smart Contract Execution Failure**

When transferring TRC-20 tokens (like USDT), the transfer involves **invoking a smart contract**. If the contract fails for any reason (e.g., invalid address, incorrect amount), the transaction fails — and **the energy consumed won’t be refunded**.

**Solution:**

* Double-check the **recipient address** and **amount**.
* Ensure the destination address supports **TRC-20 tokens** like USDT.

***

#### 4. **Frozen Resource Limitations**

On TRON, users can freeze TRX to gain Energy and Bandwidth. If the amount of **frozen TRX is too low**, your account may lack enough resources. Even if you've rented energy, **insufficient bandwidth from freezing** can still cause the transaction to fail.

**Solution:**

* Freeze additional TRX to gain more Bandwidth and Energy.
* Ensure your frozen resources are sufficient to support the transaction.

***

#### 5. **Network Congestion**

During times of **heavy network usage**, transactions might fail due to resource exhaustion or long queues. Even if you have enough Energy and Bandwidth, congestion may prevent your transaction from being processed in time.

**Solution:**

* Wait for network congestion to ease before retrying the transaction.
* Avoid peak hours or purchase extra resources to increase transaction priority.

***

#### 6. **Transaction Signature or Network Issues**

A failed **signature** or unstable **network connection** during transaction submission can also cause the transfer to fail. These issues typically occur during the signing process or when the transaction is broadcasted to the network.

**Solution:**

* Make sure the transaction is **correctly signed** and conforms to TRON's requirements.
* Check your **internet connection** and ensure network stability before submitting the transaction.

***

#### Summary

Even after renting energy, transfer failures on TRON may be caused by:

* **Insufficient Energy** (especially if the recipient doesn’t already have USDT)
* **Insufficient Bandwidth**
* **Smart Contract execution errors**
* **Lack of frozen TRX resources**
* **Network congestion**
* **Signature or connection issues**

**Solutions** include increasing your Energy and Bandwidth, double-checking transaction parameters, and ensuring the TRON network is not congested at the time of the transfer. If issues persist, consider contacting your energy provider (such as [**CatFee.IO**](https://catfee.io/)) or reaching out to TRON official support for help.
