If you are one of those users who do many transactions in the Ethereum wallet, you have probably encountered the problem that you can not create new transactions due to the pending transaction issue. Sometimes you even face issues such as waiting too long for a transaction to occur, and you may have to wait for hours to occur, but this does not happen. This problem is in most cryptocurrencies. But how can it be fixed?

Because Ethereum blockchain transactions must be processed in queues, they will either encounter an error entering the above number of transactions or wait for hours for the transaction to occur. But we will explain why and how this happens in the following.
Why does the transaction lock?
One of the main reasons your transaction encounters an error, and the execution process delays are that no miner selects your transaction to perform. In general, in the Ethereum blockchain, a gas fee is set for each transaction, according to which each miner who chooses the transaction and performs it receives a certain amount as a reward based on the gas fee. Now consider that sometimes the adjusted gas fee is not so high that the miner wants to do the transaction, so the process cancels. However, the first thing you can do is first cancel the transaction and increase the gas fee.
How do I know which fee (gas price) is sufficient?
Many Ethereum wallets, such as Metamask, automatically calculate the transaction gas fee by connecting to the Ethereum blockchain network. But if your transaction is still not set due to the low gas fee, you can manually increase it in the gas fee setting section of Metamask wallet.
Other wallets, such as TrustWallet, also have the option to adjust the gas fee manually. You can get this information through the Etherscan website and the gas tracker section to determine how much you need to set for each transaction.
How to fix a pending transaction error?
If your transaction is not completed due to a low gas fee, you can set another transaction with a higher gas fee once and send it to the Ethereum blockchain. Similarly, the previous transaction automatically cancels, and the new transaction with a higher gas fee is selected more quickly by a miner, and the process is done.
In Ethereum blockchain transaction queuing, each transaction has a unique number known as the nonce. If the nonce of the new transaction is greater than the previous transaction, if the original transaction is not feasible, the latest transaction replaces it and executes quickly.
On the other hand, if you can set the transaction number equal to the previous transaction, which can no longer be done due to the low gas fee, the transaction with a higher gas fee will replace the previous one and will be done.
Wallets that calculate the amount of gas fee
Some Ethereum wallets can calculate the gas fee automatically to reduce the amount of work you do at this point. Venly wallet or Metamask, for example, both have such a system.
What does pending transaction mean?
There are several reasons why a transaction places in Pending mode. The meaning of pending here is that the blockchain network has not yet approved the transaction, and no miner has selected it for processing. The amount of time required to approve a transaction on the network depends on the cost of the transaction and network competition.
The pending sign removes when the transaction is confirmed, and a transaction address is assigned to it.
Why the transaction get stuck?
Transaction operations are exactly like bank checks, which may take 2 to 3 days. Digital asset networks have also reduced this trend to a few hours and sometimes a few minutes. But due to the high competition in this network and the small number of miners who can approve the transaction, you sometimes encounter pending transactions.
In general, there are several reasons for a transaction to be in pending mode, including the following:
- You are receiving a transaction with a low gas fee or fee set to complete the transaction. As we explained, blockchain is a competitive system, and miners reward your transaction, so each person must set a transaction fee to be selected sooner. If the cost is low, the transaction process may not be completed at all.
- If you want to send an account of a digital asset that has not yet been verified, the transaction will probably remain in pending mode. Suppose you have received a cryptocurrency elsewhere, but it has not yet wholly entered your digital wallet, and you want to send part of it to another address. In that case, there will undoubtedly be a pending transaction error.
- If the blockchain network is experiencing a lot of traffic, your transaction will likely remain in pending mode for hours, in which case you will have to wait for the volume of blockchain network transactions to decrease so that you can complete the process.
- If the transaction is not done after the specified hours, it returns to the sender, and you will have the property you sent back in your wallet.
The amount of time expected to confirm the transaction in different blockchains
| Asset | Typical Pending Time |
| Bitcoin | 60 minutes or less |
| Monero | 20 minutes or less |
| Dash | 15 minutes or less |
| Binance Coin | 5 minutes or less |
| Ethereum | 5 minutes or less |
| Cardano | 5 minutes or less |
| Solana | 5 minutes or less |
Conclusion
There are many reasons why and how a pending transaction error occurs. So your transaction is not performed in the blockchain network. You can either wait or increase the transaction cost to fix the error and complete the new transaction faster.
