Type Definition polkadot_primitives::v2::Remark

pub type Remark = [u8; 32];

The information that goes alongside a transfer_into_parachain operation. Entirely opaque, it will generally be used for identifying the reason for the transfer. Typically it will hold the destination account to which the transfer should be credited. If still more information is needed, then this should be a hash with the pre-image presented via an off-chain mechanism on the parachain.
