How to debug smart contracts with your AI

Connect Infura to your AI client to access live Ethereum data. Once connected, your agent can inspect contract code and troubleshoot transaction failures.

Short answer

How can I use AI to debug smart contracts?

Your AI pulls real-time data from the Ethereum network to inspect deployed bytecode and transaction history. This lets your agent pinpoint why a function reverted or how contract state changed. You get a clear breakdown of the execution logic and error logs.

Debugging outcomes.

What your AI finds.

The AI uses on-chain data to deliver these specific insights.

CODE

Bytecode verification

The AI pulls the deployed bytecode to confirm the logic on-chain matches your local source code.

STATE

State inspection

Your agent checks current contract variables and balances to see if the state is what you expect.

FAILURE

Revert analysis

The AI examines transaction receipts to find the specific reason a call failed or ran out of gas.

HUMAN

Manual fixes

The AI identifies the bug, but you must write and deploy the corrected contract yourself.

The workflow

What your AI does when a debug request arrives.

The AI moves from raw data retrieval to logical troubleshooting.

  1. Fetch deployed code

    The AI pulls the exact bytecode sitting at a specific address to verify the logic.

    eth_getCode

  2. Simulate calls

    Your agent runs a dry run of a function to see how it would behave with specific inputs.

    eth_call

  3. Locate transaction

    The AI finds a specific transaction in the block history using its hash.

    eth_getTransactionByHash

  4. Analyze execution

    The AI looks at the receipt to check status codes and logs for errors.

    eth_getTransactionReceipt

  • Get the bytecode for contract 0x123... and tell me if it matches my local implementation.

  • Check the receipt for transaction 0xabc... to see why it failed.

  • Simulate a call to the 'transfer' function on 0x456... with these parameters.

  • Look up the transaction details for 0xdef... and explain the logs.

FAQ

How the debugging task behaves.

  • 01

    Can the AI fix the bug in my contract automatically?

    No. The AI identifies the error and suggests a fix, but you have to perform the actual code changes and deployment.

  • 02

    Can the AI execute a transaction on my behalf?

    No. The tools only allow the AI to read data and simulate calls. It cannot sign or broadcast transactions.

  • 03

    Does the AI see my private keys?

    No. The AI only interacts with the blockchain through the Infura RPC provider. It has no access to your wallet or keys.

  • 04

    Can it debug contracts on L2 networks?

    Yes, as long as the Infura endpoint you provide supports that specific network.

  • 05

    How does it know why a transaction failed?

    It uses the transaction receipt data to inspect the status and error logs returned by the node.
