Expand description

Transfer fee extension data for mints.

Fields

transfer_fee_config_authority: OptionalNonZeroPubkey

Optional authority to set the fee

withdraw_withheld_authority: OptionalNonZeroPubkey

Withdraw from mint instructions must be signed by this key

withheld_amount: PodU64

older_transfer_fee: TransferFee

Older transfer fee, used if the current epoch < new_transfer_fee.epoch

newer_transfer_fee: TransferFee

Newer transfer fee, used if the current epoch >= new_transfer_fee.epoch
