fn deposit_stake( currency_id: Self::CurrencyId, account_id: &AccountId, amount: Self::Balance ) -> DispatchResult

fn withdraw_stake( currency_id: Self::CurrencyId, account_id: &AccountId, amount: Self::Balance ) -> DispatchResult

Withdraw a stake amount for an account_id associated to a currency_id. The account_id must have enough currency staked to perform a withdraw, if not, an Err will be returned.

fn compute_reward( currency_id: Self::CurrencyId, account_id: &AccountId ) -> Result<Self::Balance, DispatchError>

Computes the reward the account_id can receive for a currency_id. This action does not modify the account currency balance.

fn claim_reward( currency_id: Self::CurrencyId, account_id: &AccountId ) -> Result<Self::Balance, DispatchError>

Computes the reward the account_id can receive for a currency_id and claim it. A reward using the native currency will be sent to the account_id.

fn account_stake( currency_id: Self::CurrencyId, account_id: &AccountId ) -> Self::Balance

Retrieve the total staked amount of currency in an account.
