Quick Facts
- Definition:
- Transaction Bundle Error occurs in an EVM (Ethereum Virtual Machine) when a transaction bundle has been malformed or is invalid, preventing it from being included in a block.
- Causes:
- It is often triggered by a mismatch in the gas costs, an incorrect maximum transaction fee (maxFeePerGas), or a broken transaction dependency chain.
- Error Receipt:
- The error is logged in the block explorer as a Transaction Bundle Error with an EVM error code (e.g., ” Transaction bundle error: Invalid transaction dependency chain “).
- Dependency Chain:
- It occurs when the gas costs of a dependent transaction chain do not match with the expected costs of its child transactions.
- Gas Costs Mismatch:
- Gas costs mismatch can result in the refusal to process the transaction by the miners as it might lead to non-termination of the program.
- Transaction Bundle Size Limitations:
- Each transaction bundle can consist of multiple transactions but with gas cost constraints such as Bundle Gas Limit (31 million).
- Parent and Child Bundles:
- To keep track of dependencies in transactions so it maintains accurate record and will cancel the operation if dependency fails between parent and child transactions.
- Transaction R and S Component:
- Each transaction’s signature component is checked in a bundle when verification fails the Transaction Bundle error is triggered.
- Correcting Errors:
- In the case of a transaction Bundle error the user can, Increase the gas limit, provide higher gas fees, verify dependencies.
- Blockchain Explorer Log Analysis:
- Analyzing blockchain logs for an error to occur to see the reason of transactions which aren’t processed, an error could indicate that other bundles in the block could also be problematic and thus if there is lots of errors such as gas failures then re-execution from the start on node to apply is necessary.
Transaction Bundle Error: A Technical Analysis
At TradingOnramp.com, we understand the importance of seamless trading experiences. However, even with the best systems in place, errors can still occur. One such error is the Transaction Bundle Error (TBE). In this article, we will delve into the world of TBE, exploring its causes, effects, and potential solutions.
What is a Transaction Bundle Error?
A Transaction Bundle Error occurs when a group of trades, bundled together for execution, fail to complete due to errors in one or more of the trades. This can lead to partial fills, rejects, or even complete cancellation of the bundle.
Causes of Transaction Bundle Error
There are several reasons why a TBE may occur:
- Insufficient Funds: When the account balance is insufficient to cover the total cost of the trades in the bundle.
- Invalid Order Parameters: Incorrect or missing order parameters, such as quantity, price, or time-in-force, can cause the bundle to fail.
- Market Volatility: Rapid market movements can lead to price mismatches or order queuing issues, resulting in TBEs.
- System Congestion: High volumes of trades can overwhelm the trading system, increasing the likelihood of errors.
Effects of Transaction Bundle Error
A TBE can have significant consequences for traders, including:
- Financial Losses: Partial fills or cancellations can result in unexpected losses or missed opportunities.
- Order Delays: Bundles may be delayed or queuing, leading to missed market moves.
- System Downtime: In severe cases, TBEs can cause system crashes or downtime, further exacerbating the issue.
Identifying Transaction Bundle Errors
To minimize the impact of TBEs, it is essential to identify them quickly. Here are some common signs of a TBE:
- Error Messages: System-generated error messages, such as ” Bundle rejected due to insufficient funds.”
- Partial Fills: Incomplete executions, where only some trades in the bundle are filled.
- Delayed Order Reports: Slow or missing order reports, indicating issues with the bundle.
Preventing Transaction Bundle Errors
While it is impossible to eliminate TBEs entirely, several strategies can help minimize their occurrence:
| Strategy | Description | Benefits |
|---|---|---|
| Pre-Bundle Validation | Verify order parameters and account balances before submitting the bundle. | Reduced errors due to incorrect parameters or insufficient funds. |
| Real-time Monitoring | Continuously monitor the bundle’s status, allowing for quick identification and resolution of issues. | Swift response to errors and reduced downtime. |
| Error Handling Mechanisms | Implement automated error handling procedures to address TBEs. | Minimized impact on trading operations and reduced losses. |
Case Study: Real-Life Example of Transaction Bundle Error
In a recent instance, a trader submitted a bundle of 10 trades, with a total value of $100,000. However, due to an error in the order parameters, the system rejected the entire bundle. The trader lost out on potential gains and incurred significant losses due to the missed market opportunity.
Best Practices for Resolving Transaction Bundle Errors
When dealing with a TBE, follow these best practices:
- Act Quickly: Address the error promptly to minimize its impact.
- Verify Order Parameters: Double-check the order details to ensure accuracy.
- Communicate with the Trading Desk: Inform the trading desk to facilitate manual intervention, if necessary.
- Analyze and Adjust: Review the bundle and adjust as needed to prevent future errors.

Transaction Bundle Error FAQ
What is a Transaction Bundle Error?
A Transaction Bundle Error occurs when a set of transactions, bundled together for simultaneous processing, fails to process successfully. This can happen due to various reasons, such as incorrect data, network connectivity issues, or system failures.
Q: What causes a Transaction Bundle Error?
A: Transaction Bundle Errors can be caused by a variety of factors, including:
- Incorrect data: Incomplete or incorrect data within the transaction bundle can lead to errors.
- Network connectivity issues: Problems with internet connection or network infrastructure can cause transaction bundles to fail.
- System failures: Technical issues with the processing system can result in errors.
- Timeouts: If the transaction bundle takes too long to process, it may time out, resulting in an error.
Q: How can I resolve a Transaction Bundle Error?
A: To resolve a Transaction Bundle Error, try the following steps:
- Verify the transaction bundle: Check the transaction bundle for any errors or inconsistencies.
- Check network connectivity: Ensure that your internet connection is stable and working correctly.
- Retry the transaction bundle: Attempt to reprocess the transaction bundle.
- Contact support: If the issue persists, contact the processing system’s support team for assistance.
Q: Can I prevent Transaction Bundle Errors?
A: Yes, there are steps you can take to minimize the likelihood of Transaction Bundle Errors:
- Verify data before sending: Ensure that all data within the transaction bundle is accurate and complete.
- Use a reliable processing system: Choose a processing system with a good reputation for reliability and uptime.
- Regularly update software and systems: Keep your software and systems up-to-date to ensure you have the latest security patches and features.
Q: What happens to the transactions in a failed bundle?
A: When a transaction bundle fails, the individual transactions within the bundle may be:
- Rolled back: Reverted to their original state, as if the transaction had never occurred.
- Retried: Automatically retried by the processing system, if possible.
- Cancelled: Cancelled and require manual reprocessing.
