In order to claim your Spark Tokens, you must self custody your XRP (unless on a supported exchange) and sign the MessageKey with an ETH compatible flare address.
An ETH compatible Flare address can be generated by creating an ETH address through MyEtherWallet.
A snapshot will be taken of the XRP ledger at 00:00 GMT on 12th December 2020, however you have 6 months from the snapshot date to setup your XRP MessageKey and you will still be eligible to receive the Spark Tokens once set.

The message key format must be in the form of:
02 + 24 zeros + the ETH compatible address (which should be UPPERCASE with the 0x removed).

If your XRP was on a supported exchange, you don’t need to setup a message key, the exchange will do it for you. Please also note that none of the tools to show your FLR claim will work because they are built only for self custody XRP hodlers.
