# How to Dispute

### Tutorial

* First you'll need to monitor the transactions that reporters submit on chain and identify a data report that you'd like to dispute.  You can do that using our [feeds page](https://feed.tellor.io), or the [oracle contract](https://docs.tellor.io/tellor-docs-v2/the-basics/contracts-reference) directly.
* In order to dispute you'll need to collect the queryId and time from the data in the transaction log.

* Next, locate the [correct governance contract](https://docs.tellor.io/tellor-docs-v2/the-basics/contracts-reference) depending on which chain the data resides on.  
* Connect wallet funded with TRB and call the `beginDispute` function and input the `queryId` and `timestamp.`
