Constants

const (

	ModuleName = "bank"

	// StoreKey defines the primary module store key
	StoreKey = ModuleName

Functions

func AddressFromBalancesStore

func AddressFromBalancesStore(key []byte) sdk.AccAddress

AddressFromBalancesStore returns an account address from a balances prefix store. The key must not contain the perfix BalancesPrefix as the prefix store iterator discards the actual prefix.

func DenomMetadataKey

func DenomMetadataKey(denom string) []byte

DenomMetadataKey returns the denomination metadata key.

func Migrate

func Migrate(
	bankGenState v038bank.GenesisState,
	authGenState v039auth.GenesisState,
	supplyGenState v036supply.GenesisState,
) *types.GenesisState

Migrate accepts exported v0.39 x/auth and v0.38 x/bank genesis state and migrates it to v0.40 x/bank genesis state. The migration includes:

- Moving balances from x/auth to x/bank genesis state. - Moving supply from x/supply to x/bank genesis state. - Re-encode in v0.40 GenesisState.

func RegisterInterfaces

func RegisterInterfaces(registry codectypes.InterfaceRegistry)

RegisterInterfaces registers interfaces required for the v0.40 migrations.

Types

type SupplyI

type SupplyI interface {
	proto.Message
}

SupplyI defines an inflationary supply interface for modules that handle token supply. It is copy-pasted from: https://github.com/cosmos/cosmos-sdk/blob/v042.3/x/bank/exported/exported.go where we stripped off the unnecessary methods.

It is used in the migration script, because we save this interface as an Any in the supply state.

Deprecated.
