Expand description

Methods required in token transfer execution, to be implemented by the host.

Required Methods§

Source

fn escrow_coins_execute( &mut self, from_account: &Self::AccountId, port_id: &PortId, channel_id: &ChannelId, coin: &PrefixedCoin, memo: &Memo, ) -> Result<(), HostError>

Executes the unescrow of the tokens in a user account.

Source

fn mint_coins_execute( &mut self, account: &Self::AccountId, coin: &PrefixedCoin, ) -> Result<(), HostError>

Executes minting of the tokens in a user account.

Source

fn burn_coins_execute( &mut self, account: &Self::AccountId, coin: &PrefixedCoin, memo: &Memo, ) -> Result<(), HostError>

Executes burning of the tokens in a user account.
