Confidential transfer fee extension data for mints

Fields

authority: OptionalNonZeroPubkey

Optional authority to set the withdraw withheld authority ElGamal key

withdraw_withheld_authority_elgamal_pubkey: ElGamalPubkey

If false, the harvest of withheld tokens to mint is rejected.

withheld_amount: EncryptedWithheldAmount

Withheld confidential transfer fee tokens that have been moved to the mint for withdrawal.
