No. Neither Swan nor your custodian can loan, hypothecate, or rehypothecate any Bitcoin. Your Bitcoin is held in your own legal trust account until you decide to withdraw it.
As always, we strongly encourage you to withdraw Bitcoin to your own custody. If you are not familiar with self-custody, please refer to our wallets FAQ and related blog post for more information. In addition, we would be happy to help you via our help form if you would like assistance or have any questions about self-custody.
