All XRP (Ripple) owners barring Ripple Labs and certain previous employees of Ripple Labs can claim the Spark token! The snapshot of XRP wallets is supposed to happen on December 12th 2020 (XRP utility fork launching in December).
If you do not want to bother with this process, we do recommend you to send your XRP tokens to an exchange that will support SPARK and they will handle it for you! Send the tokens to the exchange a couple of days before December 12th (start exploring options a week before, more information will be available by then). Once you will get the SPARK tokens on the exchange, you can send your XRP back to the BC Vault.
This is the easiest and most convenient way to not miss out on SPARK!
