How Much Energy is Required for USDT Transfers on TRON?

On the TRON network, transferring USDT (TRC-20 tokens) consumes two main resources: Energy and Bandwidth. These resources pay for the computation and storage fees of transactions. The specific resource consumption varies depending on whether the destination address already contains USDT.

How Much Energy and Bandwidth is Needed for USDT Transfers?

1. If the destination address already has USDT:

   • Energy requirement: 64,285 Energy (without Energy, approximately 13.5 TRX will be burned)
   • Bandwidth requirement: 350 Bandwidth

2. If the destination address does not have USDT:

   • Energy requirement: 130,285 Energy (without Energy, approximately 27.7 TRX will be burned)
   • Bandwidth requirement: 350 Bandwidth

Why is There a Difference?

TRC-20 tokens are implemented through smart contracts, and transferring USDT is essentially calling the transfer() method of the TRC-20 contract. Different transfer scenarios may consume different amounts of energy:

• If the target address already has USDT, the TRON network can process the transfer operation more efficiently, requiring less energy.
• If the target address does not have USDT, the network needs to perform more initialization operations, resulting in higher energy consumption.

Recommended Energy Purchase

Since TRON's resource model is dynamic, it's recommended to purchase slightly more energy to ensure you can handle network resource fluctuations and avoid transfer failures due to insufficient resources:

• If the destination address already has USDT, we recommend purchasing 65,000 Energy.
• If the destination address does not have USDT, we recommend purchasing 131,000 Energy.

This approach ensures your transfers will complete successfully even under network congestion or other influencing factors.

TRON Network Resource Model

TRON's resource model is based on Energy and Bandwidth, where:

• Energy: Primarily used to pay for computational resources required for smart contract calls and execution. Each call to a TRC-20 contract (such as transferring USDT) consumes a certain amount of energy.

• Bandwidth: Used to pay for storage and transmission fees of transaction data. Simple TRX transfers generally consume bandwidth, while TRC-20 token transfers may consume both energy and bandwidth.

How to Obtain Energy?

1. Freeze TRX to Obtain Energy

On the TRON network, users can obtain energy and bandwidth by freezing TRX. Frozen TRX generates corresponding resources, and during the freezing period, users cannot freely transfer these TRX but can utilize the resources.

• Freezing TRX is a long-term holding method. Once the frozen TRX is unfrozen, the energy and bandwidth will disappear, but the resources are effective during the freezing period.
• After freezing a certain amount of TRX, the system automatically allocates energy and bandwidth. The more TRX frozen, the higher the energy and bandwidth.

2. Purchase Energy Through the EOPEN Platform

If you don't want to freeze TRX, or if the energy generated by your frozen TRX is insufficient, you can choose to purchase energy from the EOPEN.IO platform. The advantage of purchasing energy is flexibility and immediacy, without waiting for a freezing period.

On the EOPEN TRON Energy Platform, you can:

• Directly purchase the energy needed to pay for smart contract operations
• Use purchased energy immediately for transfers, smart contract calls, and other operations
• Choose different rental durations according to your needs, ranging from 10 minutes to 30 days

Why Do Transfers Still Fail After Renting Energy?

If you've rented sufficient energy but transfers still fail, there might be several reasons:

1. Insufficient Energy

Although you've rented energy, it might still be insufficient to complete the transaction. This could be because:

• The amount of energy rented is lower than actually needed
• Network congestion increases energy consumption
• The target address status differs from expectations (for example, you thought the target address already had USDT, but it actually doesn't)

Solution: Ensure you rent enough energy, recommending an additional 5-10% as a buffer.

2. Insufficient Bandwidth

While USDT transfers primarily consume energy, they also require a small amount of bandwidth. If your account doesn't have enough bandwidth, the transaction will fail.

Solution: Ensure your account has sufficient bandwidth, which can be obtained by freezing a small amount of TRX.

3. Receiving Address Issues

If there are problems with the receiving address, it can also cause transaction failures:

• Incorrect receiving address format
• The receiving address is a contract address but doesn't support direct USDT reception
• The receiving address is frozen or has other restrictions

Solution: Carefully check the receiving address to ensure its format is correct and it can normally receive USDT.

4. Network Congestion or Delays

During periods of network congestion, transactions may temporarily appear to fail due to network delays, even with sufficient energy.

Solution: Wait patiently for a few minutes, then check the transaction status. If it still fails, try initiating the transaction again.

5. Smart Contract Limitations

Some smart contracts may have specific limitations or requirements that cause transaction failures.

Solution: Review the error message to understand the specific reason for failure. If it's caused by smart contract limitations, you may need to adjust transaction parameters or contact the contract developer.

Related Knowledge: TRC-20 and TRON Network

TRC-20 is a token standard on the TRON network, similar to Ethereum's ERC-20 standard. TRC-20 tokens are issued and managed through TRON's smart contracts and are widely used in DeFi, NFTs, and other blockchain projects.

• TRC-20 tokens require energy to execute smart contracts. When users make transfers, they are essentially calling the transfer() method of the TRC-20 contract.
• TRX transfers only consume bandwidth, which is used to pay for the storage and transmission fees of transactions.

Conclusion

The energy and bandwidth resources required for USDT transfers are as follows:

• Destination address already has USDT: Consumes 64,285 Energy and 350 Bandwidth.
• Destination address does not have USDT: Consumes 130,285 Energy and 350 Bandwidth.

Recommended energy purchases:

• If the destination address already has USDT, we recommend purchasing 65,000 Energy.
• If the destination address does not have USDT, we recommend purchasing 131,000 Energy.

If your account doesn't have enough energy, you can choose to purchase energy through the EOPEN.IO platform to supplement energy and bandwidth, ensuring smooth transactions.
