Once you initiate a Transfer, the funds will leave your Ledn BTC or USDC Transaction account and be held until they are accepted by the receiver. If the receiver does not accept the Transfer within 30 days, the Transfer will be canceled and the funds will be returned to your Transaction account.
If you are the receiver, you will not start generating interest on the transferred funds, until you have moved the funds from your Transaction account to your Growth account, if Growth accounts are available.
