	ConsensusParamsKeeper *consensusparamkeeper.Keeper

	UExecutorKeeper  *uexecutorkeeper.Keeper
	URegistryKeeper  *uregistrykeeper.Keeper
	UValidatorKeeper *uvalidatorkeeper.Keeper
	UTssKeeper       *utsskeeper.Keeper
}

type ModuleManager

type ModuleManager interface {
	RunMigrations(ctx context.Context, cfg module.Configurator, fromVM module.VersionMap) (module.VersionMap, error)
	GetVersionMap() module.VersionMap
}

type Upgrade

type Upgrade struct {
	// Upgrade version name, for the upgrade handler, e.g. `v7`
	UpgradeName string

	// CreateUpgradeHandler defines the function that creates an upgrade handler
	CreateUpgradeHandler func(ModuleManager, module.Configurator, *AppKeepers) upgradetypes.UpgradeHandler
	StoreUpgrades        storetypes.StoreUpgrades
}

Upgrade defines a struct containing necessary fields that a SoftwareUpgradeProposal must have written, in order for the state migration to go smoothly. An upgrade must implement this struct, and then set it in the app.go. The app.go will then define the handler.
