On Ethereum and other blockchains, not all transactions are successful. A transaction may fail due to various reasons, including insufficient gas, faulty smart contracts, or data errors. Monitoring these failed transactions can provide valuable insights into the network's health, identify potential issues with your transactions, and help improve your application's user experience. This blog post will explore why it's important to monitor failed transactions and how you can easily do it using Tatum SDK.

Understanding failed transactions

• Origin: Failed transactions occur when an attempted transaction does not successfully execute on the blockchain. This could be due to several reasons such as insufficient gas, incorrect contract calls, or even faulty smart contract code.
  
  
• Visibility: These transactions, although failed, are still recorded on the blockchain and consume gas, making them a relevant aspect to monitor, especially for developers and businesses running applications on the network.

Why monitor failed transactions?

Monitoring failed transactions on blockchain networks holds significant importance in diagnosing issues, improving user experience, and gaining insights into network health. Let's delve into the reasons why monitoring failed transactions is crucial:

• Diagnosing Issues: Failed transactions serve as valuable diagnostic tools, offering insights into potential issues with smart contract code or user input. By monitoring and analysing failed transactions, developers can identify and troubleshoot problems efficiently. These insights enable them to refine their code, improve transaction processes, and enhance the overall reliability of their applications.
• Improving User Experience: Promptly monitoring and reacting to failed transactions can greatly improve the user experience of blockchain applications. When a transaction fails, notifying the user promptly and providing guidance on resolving the issue helps maintain transparency and fosters trust. By offering clear instructions or alternative solutions, you can ensure a smoother user experience and enhance user satisfaction.
• Network Health Insights: The number of failed transactions can provide valuable insights into the health of the network. A sudden increase in failed transactions may indicate network congestion or other underlying issues. Developers and investors can leverage this information to make informed decisions, adjust their strategies, and allocate resources appropriately. Monitoring failed transactions helps identify potential bottlenecks and contributes to the overall stability and scalability of the blockchain network.

The challenge of monitoring failed transactions

Manually monitoring failed transactions requires fetching and analyzing every transaction in every block, which is highly resource-intensive. It would require running a full node, which comes with significant infrastructure and maintenance costs.

Tatum SDK for failed transactions

Tatum SDK makes monitoring failed transactions effortless. With a few lines of code, you can set up notifications for all failed transactions in each new block.

Setting up Failed Transaction Monitoring with Tatum SDK:

In this code snippet, we initialize the Tatum SDK for the Ethereum network. We then subscribe to failed transactions per block using the `notification.subscribe.failedTxsPerBlock` method.

Monitoring failed transactions is crucial for diagnosing issues, improving user experience, and understanding network health. Tatum SDK simplifies this process, eliminating the need for resource-intensive infrastructure and making it accessible to all developers. With Tatum SDK, you can stay informed about all failed transactions and swiftly react to improve your application's performance and user experience.

To simplify monitoring failed transactions in a block and improve the user experience, developers can leverage the Tatum SDK for efficient and reliable monitoring.
