func (k Keeper) SlashLockupsForValidatorSlash(ctx sdk.Context, valAddr sdk.ValAddress, infractionHeight int64, slashFactor sdk.Dec)

SlashLockupsForValidatorSlash should be called before the validator at valAddr is slashed. This function is responsible for inspecting every intermediate account to valAddr. For each intermediate account IA, it slashes every constituent delegation behind IA. Furthermore, if the infraction height is sufficiently old, slashes unbondings Note: Based on sdk.staking.Slash function review, slashed tokens are burnt not sent to community pool we ignore that, and send the underliyng tokens to the community pool anyway.

func (Keeper) SuperfluidDelegate

func (k Keeper) SuperfluidDelegate(ctx sdk.Context, sender string, lockID uint64, valAddr string) error

SuperfluidDelegate superfluid delegates mer equivalent amount the given lock holds. The actual delegation is done by using/creating an intermediary account for the (denom, validator) pair and having the intermediary account delegate to the designated validator, not by the sender themselves. A state entry of IntermediaryAccountConnection is stored to store the connection between the lock ID and the intermediary account, as an intermediary account does not serve for delegations from a single delegator. The actual amount of delegation is not equal to the equivalent amount of mer the lock has. That is, the actual amount of delegation is amount * mer equivalent multiplier * (1 - k.RiskFactor(asset)).

func (Keeper) SuperfluidUnbondLock

func (k Keeper) SuperfluidUnbondLock(ctx sdk.Context, underlyingLockId uint64, sender string) error

func (Keeper) SuperfluidUndelegate

func (k Keeper) SuperfluidUndelegate(ctx sdk.Context, sender string, lockID uint64) error

SuperfluidUndelegate starts undelegating superfluid delegated position for the given lock. Undelegation is done instantly and the equivalent amount is sent to the module account where it is burnt instantly. Note that this method does not include unbonding the lock itself.

func (Keeper) SuperfluidUndelegateAndUnbondLock

func (k Keeper) SuperfluidUndelegateAndUnbondLock(ctx sdk.Context, lockID uint64, sender string, amount sdk.Int) (uint64, error)

SuperfluidUndelegateAndUnbondLock unbonds given amount from the underlying lock that has been used for superfluid staking. This method returns the lock id, same lock id if unlock amount is equal to the underlying lock amount. Otherwise it returns the newly created lock id. Note that we can either partially or fully undelegate and unbond lock using this method.

TotalBondedTokens implements govtypes.StakingKeeper
