Struct pallet_nomination_pools::adapter::DelegateStake
source · pub struct DelegateStake<T: Config, Staking: StakingInterface, Delegation: DelegationInterface>(/* private fields */);Expand description
A staking strategy implementation that supports delegation based staking.
In this approach, first the funds are delegated from delegator to the pool account and later
staked with Staking. The advantage of this approach is that the funds are held in the
user account itself and not in the pool account.
This is the newer staking strategy used by pools. Once switched to this and migrated, ideally
the TransferStake strategy should not be used. Or a separate migration would be required for
it which is not provided by this pallet.
Use migration::unversioned::DelegationStakeMigration to migrate to this strategy.
