## Receiver Hooks
The staking module allow for the following hooks to be registered with staking events:
``` golang
// event hooks for staking validator object
type StakingHooks interface {
OnValidatorCreated(ctx Context, address ValAddress) // Must be called when a validator is created
OnValidatorModified(ctx Context, address ValAddress) // Must be called when a validator's state changes
OnValidatorRemoved(ctx Context, address ConsAddress, operator ValAddress) // Must be called when a validator is deleted
OnValidatorBonded(ctx Context, address ConsAddress) // called when a validator is bonded
OnValidatorBeginUnbonding(ctx Context, address ConsAddress, operator ValAddress) // called when a validator begins unbonding
OnDelegationCreated(ctx Context, delAddr AccAddress, valAddr ValAddress) // called when a delegation is created
OnDelegationSharesModified(ctx Context, delAddr AccAddress, valAddr ValAddress) // called when a delegation's shares are modified
OnDelegationRemoved(ctx Context, delAddr AccAddress, valAddr ValAddress) // called when a delegation is removed
}
```
