Struct NativeToken

#[repr(C)]
pub struct NativeToken {}

Implementations

impl NativeToken

pub fn initialize( env: &mut Env<'_>, (own_address, own_balance): (&Address, &mut MaybeData<Slot>), max_issuance: &Balance, ) -> Result<Self, ContractError>

Initialize native token on a shard with max issuance allowed by this shard.

Block rewards will be implemented using transfers from native token’s balance.

pub fn balance(target: &MaybeData<Slot>) -> Balance

pub fn transfer( env: &mut Env<'_>, (from_address, from): (&Address, &mut MaybeData<Slot>), to: &mut MaybeData<Slot>, amount: &Balance, ) -> Result<(), ContractError>
