My Crypto Transaction Is Stuck Unconfirmed – Changelly

why is my transaction stuck

Anyone who has ever dealt with Bitcoin knows that there are two problems – low transaction speed and high transaction fees. In 2009, when the cryptocurrency just appeared, the issue of transaction speed was non-existent. Transactions were carried out in fractions of a second even with zero commission fees.

Today, the load on the network has increased dramatically, which has resulted in a huge number of unconfirmed transactions. However, as they say, modern problems require modern solutions. For this reason, Bitcoin Transaction Accelerators were introduced.

What Is Bitcoin Transaction Accelerator?

To prevent freezing of BTC and unconfirmed financial transactions, Bitcoin accelerators have been launched. 

A transaction accelerator is an online service that speeds up transaction processing by distributing this task over miners. 

Some BTC transaction accelerator services are paid, some are available for free. You can accelerate a BTC transaction worth 100-200 for free. When it comes to larger sums, fees will apply. 

How to Cancel Unconfirmed Transaction 

Take into consideration that cryptocurrency transactions are irreversible. Yet, if your transaction is stuck unconfirmed, some steps can be taken to cancel such a transaction. Most probably a transaction got stuck because miner’s fee was too low. Therefore, no miner wants to confirm it. To cancel a transaction, you should:

  • Check whether a transaction is confirmed. To do that, copy the Transaction ID and enter it to a cryptocurrency block explorer ( for BTC, for ETH, for GRAM, etc.)  
  • See the number of confirmations. If there are 0 confirmations, the transaction can be canceled. If not, the transaction is currently processing and can’t be reversed. 

Once you know that your transaction is not in the blockchain yet, there are several ways to get it back. Take a look at strategies that might help you cancel unconfirmed BTC transaction. 

#1. Replace by Fee (RBF) 

There are wallets that support an RBF method, for example, BitcoinCore, Bitrefill, and so on. An RPF protocol allows you to replace an unconfirmed transaction with another one with a higher miner fee.

However, this method works if you initially set up an RBF option in the wallet when sending the first transaction. Otherwise, it will not help. However, there is another way to cancel an unconfirmed transaction. 

#2. Double spend with higher miner fee

Double spending is considered to be a problem within the blockchain space. But now, it might help you reverse the transaction. Create a new transaction with the same amount of BTC as the original transaction has and send it to yourself (to your address). At this stage, don’t forget to enter a higher miner fee to avoid another stuck transaction.

Note, that you probably need to use another crypto wallet or a ceratin software that allows a double-spending feature for the transaction to be rebroadcasted to the blockchain. 

Top 5 Bitcoin Transaction Accelerators to Use in 2020

Use the below-mentioned services to speed up Bitcoin transactions: these platforms have proved to be highly efficient and reliable. Both paid and free platforms are available – choose the one that fits your budget and requirements.
