Reading Event Logs

Event Logs retrieves the on-chain events emitted by a transaction or contract and decodes them into readable form inside Cognivo Chat.

What It Does

Smart contracts emit events when things happen on-chain, such as transfers, approvals, or swaps. This tool collects those events for a transaction or contract and explains what they represent, rather than showing raw log data.

When to Use It

  • You want to understand what a transaction actually did under the hood
  • You are checking which events a contract emitted
  • You want the decoded details behind a swap, transfer, or approval

What You Need

A transaction hash or a contract address. A transaction hash is a 66-character string starting with 0x; a contract address is 42 characters starting with 0x. Mention the network if it is not Ethereum.

How to Use It

Ask in natural language inside Cognivo Chat, with no commands. For example:

Show me the event logs for transaction 0x... on Ethereum

What events did this contract emit? 0x...

Cognivo detects the request and returns the decoded events automatically.

Supported Networks

  • Ethereum
  • Base
  • BNB Chain

What the Result Shows

A readable breakdown of the events tied to the transaction or contract, decoded so you can see what each one represents. You can follow up by looking up a specific transaction or tracing an address that appears in the events.

Limitations

  • Events that a contract does not emit will not appear. This tool reports what was actually logged on-chain.
  • The transaction or contract must exist on the network you name.
