Fields

ciphertext_lo: TransferAmountCiphertext

Group encryption of the low 16 bits of the transfer amount

ciphertext_hi: TransferAmountCiphertext

Group encryption of the high 48 bits of the transfer amount

transfer_with_fee_pubkeys: TransferWithFeePubkeysInfo

The public encryption keys associated with the transfer: source, dest, auditor, and withdraw withheld authority

new_source_ciphertext: ElGamalCiphertext

The final spendable ciphertext after the transfer,

fee_ciphertext_lo: EncryptedFee

The transfer fee encryption of the low 16 bits of the transfer fee amount

fee_ciphertext_hi: EncryptedFee

The transfer fee encryption of the hi 32 bits of the transfer fee amount
