Why Does a TRON Transaction Sometimes Hang Without Confirmation?

Users of the Tron blockchain interacting with TRC-20 standard tokens may encounter a situation where a transaction that usually takes a few seconds to complete suddenly freezes without confirmation. We analyze the main reasons and provide step-by-step instructions for unblocking frozen transactions in the Tron network.

In the world of centralized online financial systems, payment for energy and computing resources is taken over by the service provider, for example, an online bank. In decentralized systems, which include cryptocurrency blockchains, these costs are paid by users. On almost all cryptocurrency blockchains, the so-called gas fee, or transaction fees, is charged only in tokens of the platform's own crypto.

Tron blockchain allows developers and smart contract callers to pay for transactions involving TRC-10 and TRC-20 tokens in more than just the native cryptocurrency – TRX. Unlike other cryptocurrencies blockchains that accept only their own crypto as a transaction fee, the Tron system also provides special resources for transactions.

Bandwidth is used mainly to pay for transactions involving TRC-10 tokens, such as transferring TRX. However, those who deal with smart contracts, i.e. TRC-20 tokens, should remember that they should also stock up on some Bandwidth for transactions involving, for example, USDT transfers or DApps development. Why are we warning you about this? After all, each user receives 600 units of this resource from the system every day for free. The daily Bandwidth limit is enough for a couple of transactions involving TRC-10 tokens, but for smart contracts, you should have a reserve of 345 units of this resource (about 0.345 TRX) per transaction. Those who frequently transfer stablecoins should remember that the daily Bandwidth limit is only enough for one transaction. As soon as the wallet's "reserves" run out, TRX will be burned at the current rate. Yes, the expense is small, but the lack of Bandwidth can be the reason for the transaction to hang if the account does not have sufficient reserves and TRX is missing.

Energy is, of course, the primary resource used to pay transaction fees on the Tron network. For some users, this is a headache, but most callers and smart contract developers already know that, if done correctly, Energy can be used to reduce transaction costs to zero.

In order to provide their wallet with enough Energy, experienced Tron users and holders of large volumes of TRX turn to staking – freezing the native crypto for a certain period and receiving Energy as “rent.”

But the most advanced ones, who save their time and do not want to withdraw large volumes of TRX from circulation for half a month, use the capabilities of the Energy rental service. It is much more convenient: there is no need to use large amounts of TRX, transactions are free, and the rental commission is 20–25% of the cost of these transactions.

But these are the methods that allow you to most effectively prevent a transaction from hanging. To understand this, let's look at the reasons for this phenomenon, due to which the user can lose the already paid fee, fail to fulfill their obligations and lose their reputation, delay the transfer of funds, not receive funds on time, etc.

Tron blockchain is distinguished by its efficiency, and the reasons for freezing or lack of (delayed) response usually depend on erroneous actions of the user or third-party services involved in the transaction – the exchange, the recipient's wallet, the exchanger website, etc.

Reason 1: Not Enough Power or TRX to Complete the Transaction

The most common reason for a transaction to hang is a lack of Energy (less often – Bandwidth) on the wallet with the absence or lack of TRX. After all, when any resource that is charged by the system to pay commissions runs out, the network switches to charging TRX. But if the wallet does not have enough native crypto, the transaction may not be completed.

To avoid this, you should definitely check the balance of assets in your wallet before interacting with TRC-20 tokens. For this purpose, Tron offers its official TronScan browser.

Here you can also check the status of the transaction, for which you should perform the following steps:

• open TronScan and enter the sender's address;
• go to transaction history;
• check if there is a transaction with the Pending status in the history.

Solution:

1. Top up your TRX wallet or rent additional Energy.
2. Try sending the transaction again.

Reason 2: High Load on the TRON Network

With a sharp increase in activity in the Tron network, the commission may increase, since in order to ensure the same level of transaction processing as with standard workload, it is necessary to use additional computing and energy capacities. In this regard, the volumes of Energy and Bandwidth in the composition of the commission may also increase. Accordingly, the TRX consumption will also increase when replacing these resources in the fee.

How to check:

• go to TronScan browser;
• go to the Network Status section;
• check the blockchain load – if this indicator exceeds 80%, there may be delays.

Solution:

1. Wait until the network load drops to standard levels.
2. Try sending the transaction again later.

Reason 3: Wallet or Exchange Error

As mentioned above, delays in response after a transaction has been completed may be due to internal processes on the side of the wallet or exchange involved in the process.

Increased waiting times are usually observed on the part of exchanges that do not have automatic processing of incoming transfers and the process is carried out manually.

How to check:

• go to TronScan browser;
• check transaction status;
• get confirmation that the problem is on the wallet or exchange side;
• contact technical support for these services.

Solution:

1. Wait for the transaction to be processed.
2. If the delay is long, contact the exchange or wallet technical support again until they resolve the problem.

Problems with transactions on the Tron network can also be related to fraudulent activities, such as spam transactions or sending empty transactions. We will not go into details, the goal of these actions is one: to make the user mistakenly copy the fraudster's address and send a transaction to it. Therefore, carefully check the addresses of not only the recipients of transactions, but also those that you give to other users.

How to Unblock a Stuck Transaction

For the above reasons for transaction hanging, different actions should be taken in each individual case:

1. If there are not enough assets on the wallet, top up the balance of TRX and Energy. Energy rental services allow you to do this in a few seconds.
2. If your wallet allows, try using the "speed up transaction" feature.
3. If the network is overloaded, please try sending the transaction again later, after making sure that the system load has returned to normal.
4. If the transaction is stuck on the exchange, or the recipient wallet is delaying the response, please contact the technical support of the relevant service.

Summarizing the above information, we conclude that transactions in the Tron blockchain can hang due to a lack of Energy, network overload, problems on the recipient wallet or exchange side. First of all, you should check the transaction status through TronScan – the official browser of the Tron eco-platform.

The most reliable and profitable way to avoid problems is to rent Energy in advance so that the transaction goes quickly and without burning TRX.

NETTS rental service will calculate the required amount of Energy for your transactions and at the time you specify, it will download the entire volume to your wallet in seconds. At the same time, you will save up to 80% of your TRX if you log in via Telegram bot. A deposit of 15 TRX will allow you not to worry about the availability of Energy for 3–5 transactions.

TRX will be taken from your deposit for rent, when you receive 65,000 or 131,000 Energy within a couple of seconds, for example, for USDT TRC-20 transfer. While without NETTS you will have to wait 14 days to release your TRX from staking – and this is about 23,000 TRX, which is not available to everyone. Or pay 13.4 or 27 TRX respectively. The difference is not difficult to calculate – here is an example of calculating the savings when renting 131,000 Energy through NETTS. Almost 80% – there are no services that will offer such a discount!

If you are not satisfied with the conditions with the deposit, go to the NETTS service through the website form. To do this, you will not need to register or create an account, as when entering through the Netts Energy Bot. This way, pre-payment is required for the ordered volume of Energy, which you receive immediately after payment and for the period you ordered.

Energy Rentals from NETTS are hassle-free transactions without burning TRX.
