  To debug smart contracts in Ethereum using Chrome DevTools, follow these steps: 1. Open the Chrome browser and go to the Ethereum blockchain explorer like Etherscan. 2. Find the transaction hash of the smart contract you want to debug. 3. Open Chrome DevTools by right-clicking on the page and selecting 'Inspect'. 4. In the DevTools window, go to the 'Network' tab and filter the requests by 'XHR'. 5. Look for the request with the transaction hash in the 'Name' column. 6. Click on the request and go to the 'Response' tab to view the contract bytecode. 7. Copy the bytecode and go to the Remix IDE. 8. In Remix, paste the bytecode in the 'Bytecode' section and click on 'Create' to deploy the contract. 9. Once the contract is deployed, go back to Chrome DevTools and refresh the page. 10. In the 'Network' tab, find the request with the transaction hash again. 11. Click on the request and go to the 'Response' tab to view the contract's state and variables. By following these steps, you can effectively debug smart contracts in Ethereum using Chrome DevTools.
