​When moving assets from Avalanche® back to Bitcoin, the bridge charges an in-kind transfer fee. The user interface does not allow transfers of less than the fee amount. If a user manually generates and issues such a transaction, the bridge will mark the transfer as invalid and not process it.

To learn more about how the bridge fees are calculated, please visit the following page.
