Quick Facts
Fact #1: Arbitrum is a layer-2 scalability solution that enables fast and low-cost transactions on the Ethereum blockchain.
Fact #2: Common causes of failed Arbitrum transactions include incorrect gas limits, wrong recipient addresses, and wrong token balances.
Fact #3: When a transaction fails, Arbitrum’s on-chain bridge will emit an event indicating the reason for failure (e.g. insufficient gas, invalid recipient, etc.).
Fact #4: To debug failed Arbitrum transactions, use the `arb-get-logs` command to retrieve the transaction’s on-chain logs.
Fact #5: Check the transaction’s gas limit and adjust it if necessary. Arbitrum recommends at least 200,000 gas for most transactions.
Fact #6: Verify that the recipient address is correct and the token balance is sufficient. Arbitrum transactions require a balance of minimum 1 wei (0.00000001 ETH).
Fact #7: For Gas-optimized transactions, use the `arb-optimize-gas` command to adjust the gas limit automatically.
Fact #8: Regularly check the Arbitrum network’s current gas prices using the `arb-gas-prices` command to ensure you’re meeting the minimum gas requirement.
Fact #9: Use Arbitrum’s `arb-tx-hash` command to generate a human-readable hash for the transaction, making it easier to identify and track.
Fact #10: If you’re still having issues, consider joining the Arbitrum community or seeking help from a qualified developer expert.

As a trader on Arbitrum, you’re likely no stranger to the frustration of failed transactions. But what happens when a transaction fails, and how can you debug it to prevent it from happening again? In this article, we’ll take a deep dive into the world of Arbitrum transactions and provide you with a step-by-step guide on how to debug failed transactions.
Understanding Arbitrum Transactions
Before we dive into debugging, let’s take a look at how Arbitrum transactions work. Arbitrum is a layer 2 scaling solution for Ethereum, which means it allows for faster and cheaper transactions than the main Ethereum network. When you make a transaction on Arbitrum, it’s first processed by the Arbitrum node, and then the result is posted to the Ethereum mainnet. This process is called “rollup” and it allows for a high degree of scalability and security.
To better understand the process, let’s break down the steps involved in an Arbitrum transaction:
- The user initiates a transaction on the Arbitrum network
- The transaction is processed by the Arbitrum node
- The result is posted to the Ethereum mainnet
- The transaction is confirmed by the Ethereum Ethereum network
Common Reasons for Failed Transactions
So, why do transactions fail on Arbitrum? There are several common reasons, including:
- Insufficient gas
- Invalid transaction data
- Network congestion
- Node errors
Let’s take a closer look at each of these reasons:
| Reason | Description | Solution |
|---|---|---|
| Insufficient gas | The transaction doesn’t have enough gas to complete | Increase the gas limit> |
| Invalid transaction data | The transaction data is incorrect or malformed | Verify the transaction data |
| Network congestion | The network is too busy to process the transaction | Wait for the network to clear |
| Node errors | The Arbitrum node is experiencing technical difficulties | Contact the node operator> |
Debugging Failed Transactions
Now that we’ve covered the common reasons for failed transactions, let’s talk about how to debug them. The first step is to check the transaction status on the Arbitrum explorer. If the transaction is marked as failed, you can try to resubmit it with a higher gas limit. If the transaction is still failing, you can try to verify the transaction data using tools like Etherscan.
Here are some steps you can take to debug a failed transaction:
- the transaction status:
- Verify the transaction data:
- Increase the gas limit:
- Contact the node operator:
Use the Arbitrum explorer to check the status of the transaction
Use tools like Etherscan to verify the transaction data
Try resubmitting the transaction with a higher gas limit
If the transaction is still failing, contact the node operator for assistance
Common Debugging Tools
There are several tools available to help you debug failed transactions on Arbitrum. Some popular options include:
- Arbitrum explorer
- Etherscan
- Truffle
- Web3.js
These tools can help you verify transaction data, check the transaction status, and even resubmit failed transactions.
Real-Life Example
Let’s take a look at a real-life example of a failed transaction on Arbitrum. Suppose you’re trying to send 10 ETH from your wallet to a friend’s wallet, but the transaction keeps failing. You check the transaction status on the Arbitrum explorer and see that it’s marked as failed due to insufficient gas. You try resubmitting the transaction with a higher gas limit, but it still fails. You then use Etherscan to verify the transaction data and realize that the recipient’s address is incorrect. You update the recipient’s address and resubmit the transaction, which is then processed successfully.
Best Practices for Preventing Failed Transactions
While debugging failed transactions is an important skill, there an even more important to prevent them from happening in the first place. Here are some best practices to keep in mind:
- Always verify the recipient’s address:
- Use a sufficient gas limit:
- Monitor network congestion:
- Use a reliable node operator:
Double-check the recipient’s address before submitting a transaction
Make sure to use a sufficient gas limit to avoid running out of gas
Keep an eye on network congestion and wait for it to clear before submitting a transaction
Choose a reliable node operator to minimize the risk of node errors
By following these best practices, you can minimize the risk of failed transactions and ensure a smooth trading experience on Arbitrum.
Frequently Asked Questions:
Debugging Failed Arbitrum Transactions FAQ
General Troubleshooting
Q: What are the common reasons for failed Arbitrum transactions?
A: Common reasons for failed Arbitrum transactions include:
* Insufficient gas budget>
* Incorrect transaction data (e.g. wrong contract address, incorrect function-call data)
* Network congestion or high gas prices
* Contract errors or bugs
* Insufficient Ether balance
Q: What are the most common error messages for failed Arbitrum transactions?
A: Some common error messages for failed Arbitrum transactions include:
* “Transaction failed: out of gas”
* “Transaction failed: execution reverted”
* “Transaction failed: contract not found”
* “Transaction failed: invalid signature”
Transaction-Specific Issues
Q: What if my transaction fails with “out of gas”?
A: If your transaction fails with “out of gas”, it means that the transaction did not have enough gas to complete execution. You can try increasing the gas budget and retrying the transaction.
Q: What if my transaction fails with “execution reverted”?
A: If your transaction fails with “execution reverted”, it means that the contract execution was rolled back and the transaction did not update the state. You can try to debug the contract logic to find the root cause of the issue.
Contract-Specific Issues
Q: What if my contract logic is causing the transaction to fail?
A: If your contract logic is causing the transaction to fail, you can try to debug the contract using tools like Remix or using the Arbitrum debugger.
Q: How do I troubleshoot contract errors or bugs?
: To troubleshoot contract errors or bugs, you can try to:
* Read the contract code and understand the logic
* Use a contract debugger or a visual debugger
* Test the contract thoroughly before deploying it to the mainnet
Network-Specific Issues
Q: What if my transactions are being dropped due to network congestion?
A: If your transactions are being dropped due to network congestion, you can try to:
* Increase the gas budget to boost the transaction priority
* Use a more robust relay node to relay your transactions
* Monitor the network congestion and try to transmit your transactions during off-peak hours
Q: How do I monitor network congestion and transaction priority?
A: You can monitor network congestion and transaction priority using tools like Etherscan, EthGasStation, or Arbiscan.
Security-Specific Issues
Q: What if my private key is compromised?
A:If your private key is compromised, you should immediately:
* Rotate your private key
* Update your client with a new private key
* Monitor your transactions closely for any suspicious activity
