How to debug failed blockchain transactions with your AI

Connect AntChain to your AI client to turn cryptic error codes into actionable insights. Once connected, your agent handles the heavy lifting of data retrieval and error analysis.

Short answer

Why did my blockchain transaction fail?

Your AI pulls the specific execution results and gas usage for a transaction hash to identify the exact cause of a revert. It then explains the error in plain English so you can fix the logic or adjust the gas settings. You'll see exactly where the execution hit a wall.

The outcomes.

Where your debugging results land.

The AI processes the raw data and sorts the findings into these categories.

LOGIC

Smart contract errors

The AI identifies failed requirements or invalid state changes. You get a clear explanation of why the contract logic rejected the call.

GAS

Gas limit issues

The AI checks if the transaction ran out of gas. It compares the gas used against the limit to show if you need to increase the cap.

DATA

Raw execution logs

The AI pulls the specific event logs and traces. You get the raw technical evidence needed to verify the failure.

HUMAN

Manual fixes needed

The AI flags issues that require you to change your code or wallet settings. It won't touch your private keys or contract code directly.

The workflow

What your AI does when a transaction fails.

The AI acts as a technical investigator, digging through the chain to find the root cause.

  1. Fetch transaction data

    The AI pulls the full execution details for a specific hash to see what actually happened on-chain.

    query_transaction

  2. Analyze execution results

    It looks at the status and error messages returned by the node to find the specific revert reason.

    query_transaction

  3. Inspect gas consumption

    The AI compares the gas used to the gas limit to determine if the transaction failed due to insufficient funds or complexity.

    query_transaction

  4. Summarize the failure

    The AI translates the technical trace into a simple explanation of what went wrong and how to prevent it next time.

  • Analyze this failed transaction hash: 0xabc123...

  • Why did this transaction fail? Check the gas usage for 0xdef456...

  • Look at the execution results for 0x789ghi and tell me why the contract reverted.

  • Compare the gas limit and gas used for transaction 0xjkl012 to see if I ran out of gas.

FAQ

How the debugging works

  • 01

    Can the AI fix my smart contract?

    No. The AI only analyzes the data and explains the error. You have to write and deploy the actual code fixes yourself.

  • 02

    Can the AI resend the transaction for me?

    No. The AI has no permission to sign or broadcast transactions. It only reads data from the blockchain.

  • 03

    Does the AI need my private keys?

    No. The AI only needs the transaction hash to query the network. It never touches your wallet or private keys.

  • 04

    What kind of errors can it find?

    It can identify revert reasons, out-of-gas errors, and issues within the execution traces.

  • 05

    Can it analyze transactions on any chain?

    It can analyze any transaction that the AntChain MCP is configured to query.
