Provides an access to mint.

Required methods

fn unbond(&mut self, unbonding_purse: &UnbondingPurse) -> Result<(), Error>

Returns successfully unbonded stake to origin account.

fn mint_transfer_direct(
    &mut self,
    to: Option<AccountHash>,
    source: URef,
    target: URef,
    amount: U512,
    id: Option<u64>
) -> Result<Result<(), Error>, Error>

Allows optimized auction and mint interaction. Intended to be used only by system contracts to manage staked purses.

fn create_purse(&mut self) -> Result<URef, Error>

Creates new purse.

fn get_balance(&mut self, purse: URef) -> Result<Option<U512>, Error>

Gets purse balance.

fn read_base_round_reward(&mut self) -> Result<U512, Error>

Reads the base round reward.

fn mint(&mut self, amount: U512) -> Result<URef, Error>

Mints new token with given initial_balance balance. Returns new purse on success, otherwise an error.

fn reduce_total_supply(&mut self, amount: U512) -> Result<(), Error>

Reduce total supply by amount. Returns unit on success, otherwise an error.
