# Speed Up Transaction

The **Speed Up Transaction** feature allows you to accelerate pending blockchain transactions without manually creating replacement transactions or worrying about duplicate transfers.

Although uncommon, network congestion can occasionally cause transactions to remain pending longer than expected. This is most likely to occur during periods of high network activity when gas fees increase rapidly.

With ZKX Wallet, you can quickly resubmit your pending transaction using a higher gas fee, giving it a higher priority for confirmation.

## **Why Transactions Become Stuck**

Blockchain networks such as PulseChain process transactions based on gas fees. During periods of increased demand, validators prioritize transactions offering higher gas prices.

If your transaction was submitted with a gas price that is too low, it may remain pending until network congestion decreases.

## **How to Speed Up a Transaction**

If a transaction remains pending:

1. Open the **Activity** section in ZKX Wallet.
2. Select the pending transaction.
3. Click **Speed Up Transaction**.
4. Choose a higher gas fee (for example, **Ape Gas**).
5. Review the updated transaction details.
6. Confirm the transaction.

The wallet will broadcast a replacement transaction with the same nonce but a higher gas fee, increasing its likelihood of being confirmed sooner.

## **Why Use Speed Up Instead of Sending Again?**

Many crypto wallets require users to manually cancel pending transactions or resend them themselves.

If this process is performed incorrectly, users may encounter problems such as:

* Duplicate transactions
* Nonce conflicts
* Confusing pending transaction states
* Accidentally sending funds multiple times

For example, if you send funds to Alice and then manually submit another transfer because the first appears stuck, you may unintentionally send the payment twice once both transactions are confirmed.

## **Smarter Transaction Management**

ZKX Wallet is designed to simplify pending transaction management and reduce these risks.

Instead of requiring manual intervention, the wallet intelligently handles transaction replacement by prioritizing the original transaction. If conflicting replacement transactions are created, duplicate executions are prevented whenever possible through proper nonce management.

This approach helps users:

* Reduce the risk of accidental duplicate transactions
* Avoid common nonce-related issues
* Resolve pending transactions more safely
* Improve the overall transaction experience during network congestion

## **When Should You Use Speed Up?**

Consider using **Speed Up Transaction** when:

* A transaction has remained pending for an unusually long period.
* Network gas fees have increased significantly since the transaction was submitted.
* You want the transaction to be confirmed more quickly without manually managing replacement transactions.

## **Important Notes**

* Speed Up Transaction does **not** modify the transaction recipient, transferred assets, or transaction data. It only increases the gas fee used to prioritize confirmation.
* A higher gas fee generally increases the probability of faster confirmation but does not guarantee immediate inclusion in a block.
* Always review the updated network fee before confirming the replacement transaction.

By automating transaction replacement and simplifying nonce management, **Speed Up Transaction** provides a safer and more reliable way to handle pending transactions while helping protect users from common mistakes that can occur with manual transaction resubmission.
