How to debug smart contracts with your AI

Connect Scrollscan to your AI client to pull real-time blockchain data. Once connected, your agent can read contract code and trace failed transactions on Scroll L2.

Short answer

How can I use AI to debug Scroll L2 smart contracts?

Your AI uses Scrollscan to fetch the exact source code and ABIs needed to understand contract behavior. It then pulls transaction receipts and internal traces to pinpoint exactly where a call failed. You get a clear breakdown of logic errors and state changes.

Where every issue lands.

Debugging outcomes

Your AI categorizes findings based on the data it pulls from the Scroll network.

LOGIC

Code analysis

The AI compares the contract's source code against its ABI to find logical flaws. You get a plain English explanation of how the functions should behave.

FAILURE

Trace errors

By looking at internal transactions, your agent identifies the specific sub-call that reverted. This shows you the exact reason for a failed execution.

STATE

Transaction status

The AI checks the finality and success of any hash. You'll see if a transaction was dropped, reverted, or completed successfully.

HUMAN

Manual review

The AI flags complex edge cases that require your eyes. You decide if the identified logic flaw warrants a code fix or a deployment change.

The workflow

What your AI does when a transaction hash or address arrives.

The AI moves from raw blockchain data to a readable explanation of contract behavior.

  1. Fetch contract data

    Your agent pulls the verified source code and the ABI to understand the contract's interface.

    get_contract_source_codeget_contract_abi

  2. Check transaction status

    The AI verifies if a specific hash succeeded or failed on the Scroll L2.

    get_tx_status

  3. Trace internal calls

    To find the root cause of a revert, the agent looks at the internal transaction list.

    get_internal_tx_list_by_hash

  4. Inspect receipts

    The AI examines the full transaction receipt to see logs and status details.

    proxy_get_transaction_receipt

  • Analyze the logic of this contract: 0x123...abc

  • Why did this transaction fail: 0xabc...123?

  • Get the ABI and source code for contract 0x456...def to explain this function.

  • Look at the internal transactions for hash 0x789...ghi and tell me which call reverted.

FAQ

How the debugging process works

  • 01

    Can the AI fix the smart contract code for me?

    No. The AI can read the code and suggest fixes, but you must manually apply any changes to the blockchain.

  • 02

    Does the AI see private transactions?

    No. The AI can only access data that is publicly available on the Scroll L2 network through the provided tools.

  • 03

    Can I use this with any AI client?

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

  • 04

    Does the AI execute transactions?

    No. This MCP is for reading and inspecting data. It cannot send transactions or interact with the blockchain on your behalf.

  • 05

    What happens if the source code isn't verified?

    If the source code isn't verified on the explorer, the AI won't be able to pull it using the source tool.
