Once your contract is deployed, you can verify it using a number of popular services. Doing so will let you users have confidence that your contract does what you claim, and will allow you to interact with it using a similar interface to what you used in Remix.
After deploying your contract, you can verify it using popular explorers like [basescan](https://sepolia.basescan.org). Verifying your contract allows users to trust that it does what you claim and enables you to interact with it using a user-friendly interface similar to Remix.

By the end of this lesson, you will be able to:

- Verify a contract on the Base Sepolia testnet and interact with it in Etherscan
- Verify a contract on the Base Sepolia testnet
- Interact with your verified contract on [sepolia.basescan.org](https://sepolia.basescan.org)

### Verify the Contract
### Verifying Your Contract

Make sure you still have the address of the contract you deployed in the last article copied to the clipboard.
First, ensure you have the address of the contract you deployed in the previous article copied to your clipboard.

You can interact with your deployed contract using Remix, the same as before, but it's also possible to interact with it through Etherscan. Paste your address in the search field to find it.
While you can interact with your deployed contract using Remix, you can also do so through [sepolia.basescan.org](https://sepolia.basescan.org). To find your contract, paste its address into the search field and click search.

### Interact with the Contract
### Interacting with Your Verified Contract

You can now interact with your contract using Etherscan. Click the _Read Contract_ button. Both of your functions will be listed here and can be tested using the web interface.
Now that your contract is verified, you can interact with it using the web interface. Click the _Read Contract_ button to see a list of your contract's functions that can be tested.

You won't have anything under _Write Contract_ because this contract doesn't have any functions that save data to state.
Note that there won't be anything under _Write Contract_ if your contract doesn't have functions that modify its state.

## Conclusion

With your contracts verified, you can interact with them using online tools and your users can be secure that your code does what you claim.
With your contracts verified, you can begin to interact with them using online tools--and your users can be confident that your code does what you claim.
