Lightspark provides a Funds Recovery Kit which allows customers to receive a file containing recovery transactions. This can be set up through the Accounts page. Once you have set up your Funds Recovery Kit, if Lightspark services were to be seriously disrupted or become permanently unavailable, you could use this Funds Recovery Kit to publish on-chain transactions to Bitcoin L1 and recover your funds - with no interaction from Lightspark.  We do not recommend using the Fund Recovery Kit in the event of a minor or temporary service disruption.  For more details, please see the Fund Recovery Kit page here https://www.lightspark.com/recovery-kit#important-notes.
