Short answer

How can I use AI to debug smart contract events?

Your AI uses the Wemix Explorer MCP to pull specific event logs and transaction extrinsics directly from the chain. It then analyzes these logs to pinpoint the exact cause of a failure. You'll get a clear explanation of the error state instead of staring at raw hex data.

Where every issue lands.

Debugging outcomes

The AI processes raw data into these specific results.

LOGS

Event extraction

The AI pulls specific event data from a transaction. You get a clean list of what actually happened on-chain.

ERRORS

Failure identification

The AI compares event logs against expected contract behavior. It identifies the specific logic error or revert reason.

TRACE

Transaction history

The AI looks at the full extrinsic to see the state before and after the call. This shows the impact of the failed interaction.

HUMAN

Manual verification

The AI provides the transaction hash and event index. You use these to verify the findings on a block explorer.

The workflow

What your AI does when the data arrives.

The AI moves from raw transaction hashes to a clear diagnosis.

  1. Fetch the transaction

    The AI grabs the full details of the specific interaction you're investigating.

    get_extrinsic

  2. Isolate the events

    The AI scans the transaction to find every event emitted during the execution.

    list_events

  3. Inspect specific logs

    The AI looks at the individual data within a single event to find the error payload.

    get_event

  4. Synthesize the error

    The AI combines the extrinsic data and event logs to explain the failure in plain English.

    get_extrinsicget_event

  • Look at the events for transaction 0x123... and tell me why the transfer failed.

  • List all events for block 456789 to see if the minting function triggered.

  • Check the details of the event at index 2 in transaction 0xabc... to find the revert reason.

  • Analyze the extrinsic 0xdef... and explain the state changes that occurred.

FAQ

How this task behaves.

  • 01

    Can the AI fix the smart contract error?

    No. The AI can only read the data and explain why the error happened. You have to write and deploy the fix yourself.

  • 02

    Can the AI execute new transactions?

    No. This MCP is read-only. It can only fetch existing data from the blockchain.

  • 03

    Does the AI see my private keys?

    No. The AI only accesses public blockchain data through the Wemix Explorer tools.

  • 04

    Can it debug events on other chains?

    No. This specific MCP is built to work with Wemix data.

  • 05

    What if the transaction is very recent?

    The AI can access any data that has been indexed and is available via the Wemix Explorer tools.
