Explorer Name Service

Since the early days of Mina's first testnets we have always displayed usernames on account pages to help users track their progress in the technical challenges.

Now that mainnet has launched, we are only displaying addresses listed on https://mina.staketab.com/ intended for use for staking providers and notable addresses such as the Foundation or O(1) Labs delegation addresses.

While we did not intend to add individual information, primarily due to privacy concerns, a number of users wish to associate their account with their address. To facilitate this we have a simple name service to display a chosen name on the account page of the account holder.

Add a name to the MinaExplorer account page

To ensure that only the address holder may update the information, a transaction must be broadcast on the Mina blockchain utilizing the memo field to the specified address. To identify this is a name request, the memo must begin with Name: You should send an amount of 0 and only pay the transaction fee. There will be a short delay in the site being updated, but you should be able to view the transaction on the Name Service wallet page.

Memos are limited to 32 characters that include the prefix.

Retrieving names via GraphQL

Obtain all name service transactions:

query memoParser {

    from

    blockHeight

    memo

}

Memos are returned Base58Check encoded. The query excludes where the memo is empty.
