How to debug smart contracts with your AI

Connect Snowtrace to your AI client once. From there, your agent can pull on-chain data to find bugs in your code or failed transactions.

Short answer

How can I use AI to debug smart contracts?

Your agent uses Snowtrace to fetch verified source code and ABIs to understand contract logic. It then inspects transaction receipts and execution statuses to find exactly why a call failed. You get a clear path to the root cause.

Debugging outcomes.

Where your findings land.

The AI categorizes its analysis into these four areas.

LOGIC

Code analysis

The AI pulls verified source code to explain how the contract works. You get a plain English breakdown of the logic.

ERRORS

Failure diagnosis

The AI checks transaction receipts to find revert reasons. It identifies if the error was due to gas, logic, or permissions.

DATA

ABI and state

The AI fetches the ABI to map function calls to data. This shows you exactly how parameters were passed.

HUMAN

Manual fixes

The AI flags complex vulnerabilities that need a developer. You decide when to rewrite code or change deployment settings.

The workflow

What your AI does when a transaction fails.

The AI follows a specific sequence to move from a raw hash to a clear explanation.

  1. Check the transaction

    The AI looks up the specific transaction to see if it succeeded or reverted.

    check_transaction_receipt_status

  2. Fetch the code

    It pulls the verified source code and the ABI to understand the contract's structure.

    get_contract_source_codeget_contract_abi

  3. Verify the logic

    The AI confirms the source code matches what is actually on the blockchain.

    verify_source_code

  4. Analyze execution

    The AI examines the execution status to find the specific point of failure.

    check_contract_execution_status

FAQ

How this task behaves.

  • 01

    Can the AI fix the smart contract for me?

    No. The AI can only read code and analyze data. You must write and deploy any fixes yourself.

  • 02

    Can the AI execute transactions on Avalanche?

    No. This MCP is for reading data and analyzing state. It cannot send transactions or move funds.

  • 03

    Does the AI work with unverified contracts?

    It can pull data, but it cannot perform source code analysis if the code isn't verified on Snowtrace.

  • 04

    Can I use this with any AI client?

    Yes, as long as the client supports the Model Context Protocol (MCP).

  • 05

    Will the AI tell me why my gas ran out?

    Yes, by checking the transaction receipt and execution status, it can identify gas-related failures.
