Required Associated Types

Required Methods

fn migrate_nominator_to_agent( agent: Agent<Self::AccountId>, reward_account: &Self::AccountId, ) -> DispatchResult

Migrate an existing Nominator to Agent account.

The implementation should ensure the Nominator account funds are moved to an escrow from which Agents can later release funds to its Delegators.

fn migrate_delegation( agent: Agent<Self::AccountId>, delegator: Delegator<Self::AccountId>, value: Self::Balance, ) -> DispatchResult

Migrate value of delegation to delegator from a migrating agent.

When a direct Nominator migrates to Agent, the funds are kept in escrow. This function allows the Agent to release the funds to the delegator.
