                            Destination tag is an arbitrary number which serves as a unique
                            identifier of your transaction. Some services may require this to
                            process your transaction. The current firmware version{' '}
                            <strong>does not support</strong> destination tags yet.
                            <br />
                            <br />
                            If the receiver requires a destination tag, do not use Trezor to send
                            XRP. We are working on adding this feature.
