The History tab on a Name page in ENS Explorer lists everything that has happened to the name onchain. That includes registrations, renewals, transfers, resolver changes, record updates and subname creations. To open it, select History in the sidebar of any Name page.

Each row in the list is one transaction, showing its date, transaction hash, sender and network. Expand a row to see the individual events inside it. Select More to open the Transaction sheet, which shows the full detail plus a panel for each event. Each panel shows the event's name and type (its signature), a Go to docs button for that event's documentation, and a Data section.

Each event's Data section has a toggle with two views of the same event. Decoded shows each parameter in a table: name, type and value. Encoded shows the raw data exactly as it was written to the blockchain. Most people never need it; developers use it to feed the bytes into their own tools.

Use the Date and Event filters or the search box to narrow the list. Expand all opens every row's events at once; select it again to collapse them. Select a transaction hash to open it on Sepolia Etherscan, a public site for viewing Ethereum transactions, for detail such as the gas paid.

When the Encoded view says the data is not available, the transaction receipt is usually still loading. Switch the toggle off and on again. If the message stays on a transaction that has already confirmed, reload the page.

Start with the Decoded view: it shows which event happened and with which values. If a value looks wrong, switch to Encoded and paste the raw data into your own tool. For the transaction as a whole, open it on Etherscan instead.
