Confidential transfer mint configuration

Fields

authority: OptionalNonZeroPubkey

Authority to modify the ConfidentialTransferMint configuration and to approve new accounts (if auto_approve_new_accounts is true)

The legacy Token Multisig account is not supported as the authority

auto_approve_new_accounts: PodBool

Indicate if newly configured accounts must be approved by the authority before they may be used by the user.

• If true, no approval is required and new accounts may be used immediately
• If false, the authority must approve newly configured accounts (see ConfidentialTransferInstruction::ConfigureAccount)

auditor_encryption_pubkey: OptionalNonZeroEncryptionPubkey

Authority to decode any transfer amount in a confidential transafer.

withdraw_withheld_authority_encryption_pubkey: OptionalNonZeroEncryptionPubkey

Authority to withraw withheld fees that are associated with accounts. It must be set to None if the mint is not extended for fees.

Note that the withdraw withheld authority has the ability to decode any withheld fee amount that are associated with accounts. When combined with the fee parameters, the withheld fee amounts can reveal information about transfer amounts.

• If not None, transfers must include ElGamal cyphertext of the transfer fee with this public key. If this is the case, but the base mint is not extended for fees, then any transfer will fail.
• If None, transfer fee is disabled. If this is the case, but the base mint is extended for fees, then any transfer will fail.

withheld_amount: EncryptedWithheldAmount

Withheld transfer fee confidential tokens that have been moved to the mint for withdrawal. This will always be zero if fees are never enabled.
