Confidential transfer mint configuration

Fields

authority: Pubkey

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

Note that setting an authority of Pubkey::default() is the idiomatic way to disable future changes to the configuration.

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_pubkey: EncryptionPubkey

• If non-zero, transfers must include ElGamal cypertext with this public key permitting the auditor to decode the transfer amount.
• If all zero, auditing is currently disabled.

withdraw_withheld_authority_pubkey: EncryptionPubkey

• If non-zero, transfers must include ElGamal cypertext 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 all zero, 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.
